True. Frequency scaling refers to increasing the clock speed of a processor to improve its performance.
However, as the frequency increases, the power consumption and heat generated by the processor also increase. This can lead to concerns about power density, which is the amount of power per unit area. To address these concerns, core scaling has become a more popular approach to improving processor performance. This involves adding more processor cores to a chip, rather than simply increasing the frequency of a single core. This allows for better performance while keeping power density under control.

if a 0.15- kg baseball with a radius of 3.7 cm is thrown with a linear speed of 48 m/s and an angular speed of 43 rad/s , how much of its kinetic energy is translational energy? assume the ball is a uniform, solid sphere.
The translational energy of the baseball is 151.88 J and the rotational energy is 0.033 J.
To calculate the translational energy of the baseball, we need to use the formula for kinetic energy:
K_trans = (1/2)mv^2
where m is the mass of the baseball and v is the linear speed. Plugging in the given values, we get:
K_trans = (1/2)(0.15 kg)(45 m/s)^2
K_trans = 151.88 J
To calculate the rotational energy of the baseball, we need to use the formula for rotational kinetic energy:
K_rot = (1/2)Iω^2
where I is the moment of inertia of the baseball and ω is the angular speed. For a uniform, solid sphere, the moment of inertia is given by:
I = (2/5)mr^2
Plugging in the given values, we get:
I = (2/5)(0.15 kg)(0.037 m)^2
I = 4.13 x 10^-5 kg*m^2

(240) What size overcurrent protection device is required for a 45 ampere continuous load? The circuit is in a raceway with 14 current carrying conductors.
For a 45A continuous load in a circuit with 14 current-carrying conductors, a 60A overcurrent protection device is required (NEC guidelines).
To decide the size of the overcurrent security gadget expected for a 45-ampere nonstop burden in a circuit with 14 current-conveying guides, you want to think about two factors: the consistent burden and the quantity of current-conveying guides.
According to NEC rules, for a nonstop burden, the overcurrent security gadget ought to be evaluated no less than 125% of the heap, which for this situation would be:
125% x 45 amps = 56.25 amps
Furthermore, for a circuit with multiple current-conveying guides, the ampacity of the guides should be changed by a derating factor. According to NEC Table 310.15(B)(3)(a), when there are 14 current-conveying guides in a raceway, the derating factor is 70%. Subsequently, the changed ampacity of the guides would be:
45 amps x 0.7 = 31.5 amps
Since the changed ampacity of the guides is not exactly the base required size of the overcurrent assurance gadget (56.25 amps), the base size overcurrent insurance gadget expected for this circuit would be 60 amps.

The head of a golf club moving at 45. 0 m/s strikes a golf ball (mass 46. 0 g) resting on a tee. The effective mass of the clubhead is 220 g. (a) with what speed does the ball leave the tee? (b) with what speed would it leave the tee if you doubled the mass of the clubhead? if you tripled it? what conclusions can you draw about the use of heavy clubs? assume that the collisions are perfectly elastic and that the golfer can bring the heavier clubs up to the same speed at impact. See question 13
Answer:
We can use the conservation of momentum and energy to solve this problem. Since the collision is perfectly elastic, both momentum and kinetic energy are conserved.
Let's first find the initial velocity of the combined club and ball system:
m_clubhead = 220 g = 0.22 kg (effective mass of the clubhead)
m_ball = 46.0 g = 0.046 kg
v_clubhead = 45.0 m/s
The initial momentum of the system is:
p_i = m_clubhead * v_clubhead = 0.22 kg * 45.0 m/s = 9.90 kg·m/s
Since momentum is conserved, the final momentum of the system is also equal to 9.90 kg·m/s:
p_f = m_clubhead * v_clubhead' + m_ball * v_ball'
where v_clubhead' and v_ball' are the velocities of the clubhead and ball after the collision, respectively.
The initial kinetic energy of the system is:
KE_i = 1/2 * m_clubhead * v_clubhead^2 = 0.5 * 0.22 kg * (45.0 m/s)^2 = 222.75 J
Since kinetic energy is conserved, the final kinetic energy of the system is also equal to 222.75 J:
KE_f = 1/2 * m_clubhead * v_clubhead'^2 + 1/2 * m_ball * v_ball'^2
Now we can solve for v_ball':
p_f = m_clubhead * v_clubhead' + m_ball * v_ball'
9.90 kg·m/s = 0.22 kg * v_clubhead' + 0.046 kg * v_ball'
KE_f = 1/2 * m_clubhead * v_clubhead'^2 + 1/2 * m_ball * v_ball'^2
222.75 J = 0.5 * 0.22 kg * v_clubhead'^2 + 0.5 * 0.046 kg * v_ball'^2
We have two equations and two unknowns (v_clubhead' and v_ball'), so we can solve for v_ball':
v_ball' = (p_f - m_clubhead * v_clubhead') / m_ball
Substituting this expression into the energy conservation equation and solving for v_clubhead', we get:
v_clubhead' = sqrt(2/m_clubhead * (m_ball * v_ball'^2 + KE_i - KE_f))
Now we can use this equation to answer the questions:
(a) With the given data, we get:
v_ball' = (9.90 kg·m/s - 0.22 kg * 45.0 m/s) / 0.046 kg = 93.70 m/s
v_clubhead' = sqrt(2/0.22 * (0.046 kg * (93.70 m/s)^2 + 222.75 J - 222.75 J)) = 45.0 m/s
Therefore, the ball leaves the tee with a speed of 93.70 m/s.
(b) If we double the mass of the clubhead, the effective mass becomes 440 g = 0.44 kg, and the initial momentum of the system doubles to 19.80 kg·m/s. Using the same equations as before, we get:
v_ball' = (19.80 kg·m/s - 0.44 kg * 45.0 m/s) / 0.046 kg = 187.41 m

A man drops a cup from cretain height which breaks in to pieces what's energy changes are involved?
There are various energy changes that occur when a guy drops a cup from a specific height. The cup's elevation above the ground gives it potential energy.
This potential energy is transformed into kinetic energy, the energy of motion, as it descends. The kinetic energy is transmitted to the cup as it falls to the ground, breaking it into pieces. This process involves the conversion of kinetic energy into thermal energy from the collision and friction of the shattered pieces with the ground as well as potential energy of the broken pieces. When a cup breaks, energy is released in the form of sound waves, which are then transmitted from the cup to the surrounding air.

The law of conservation of energy is then written as the totals mechanical energy of a system, including any nonconservative forces, is conserved only if the work done by nonconservative forces is equal to the change in mechanical energy.
The law of conservation of energy states that the total energy in a system is constant, meaning that energy cannot be created or destroyed, only transferred or converted from one form to another.
However, in the presence of nonconservative forces like friction, the total mechanical energy of the system will change over time.
In such cases, the law of conservation of energy is modified to state that the total energy of the system, including both kinetic and potential energy, is conserved, but the sum of the kinetic and potential energy may decrease due to energy lost as heat or work done against nonconservative forces.

The boxes are identical and they have the same mass. Also, since both boxes are moving at a constant speed, their acceleration is zero. Therefore, the force that Alice is applying to the box is also 55 N.
To find the magnitude of the force that Alice is applying to the box, we need to use the equation: force = mass x acceleration
Since both boxes are identical, they have the same mass. Also, since both boxes are moving at a constant speed, their acceleration is zero. Therefore, the force that Alice is applying to the box is also 55 N.
To find the magnitude of the force Alice is applying, we should first understand that the force applied is proportional to the velocity when the boxes are moving at a constant speed. Since Alice's box moves at 2.2 m/s and Bob's box moves at 1.1 m/s, Alice's box is moving twice as fast as Bob's box.
To maintain this constant speed, the force applied must also be doubled. Since Bob is applying a force of 55 N, Alice must apply a force of 2 times 55 N, which is equal to 110 N. Therefore, the magnitude of the force Alice is applying to the box is 110 N.

Compression is to crest as rarefaction is to _________.
A. Peak
B. Trough
C. Amplitude
D. Wavelength
Compression is to crest as rarefaction is to Trough.
Hence, the correct option is B.
Because
In a longitudinal wave, compression refers to the region where the particles are closer together, while rarefaction refers to the region where the particles are farther apart.
The crest and trough, on the other hand, are terms used in transverse waves to describe the highest and lowest points of the wave, respectively. Therefore, in this analogy, rarefaction is equivalent to the trough.
Hence, the correct option is B.

Given a parallel runtime of 20s on eight cores and a serial runtime of 80s, what is the runtime in seconds on 16 cores assuming the same efficiency (do not include any units in the answer)?
If we assume the same efficiency, then we can use Amdahl's Law to calculate the new runtime on 16 cores.
Amdahl's Law states that the speedup of a parallel program is limited by the portion of the program that must be executed sequentially. In this case, the portion that must be executed sequentially is (80-20)/80 = 0.75 or 75%. This means that only 25% of the program can be parallelized. Therefore, the speedup we can expect from doubling the number of cores is limited to 1/((1-0.25) + 0.25/8) = 1.85.
Using this speedup, we can calculate the new runtime on 16 cores as 20/1.85 = 10.81 seconds.

950-kg satellite orbits the earth at a constant altitude of 90-km. (b) what is the change in the system's kinetic energy?
The change in the system's kinetic energy of the 950-kg satellite orbiting the earth at a constant altitude of 90 km is zero.
This is because the satellite is orbiting at a constant altitude, meaning its distance from the Earth's center is constant, and therefore, its potential energy remains constant. When the altitude is constant, there is no change in the system's kinetic energy, as the satellite maintains the same speed and distance from the Earth. Therefore, the change in kinetic energy is 0. Since the total energy of a satellite in orbit is constant, any change in potential energy is compensated by an equal and opposite change in kinetic energy. Therefore, since the potential energy is constant, the kinetic energy must also be constant.

The current supplied to the phone is 93.75 milliamperes (mA) or 0.09375 Amperes (A).
Part (a) Expression for the average current, I, supplied to the phone:
We can use the formula for electrical power:
Power = current x voltage
The energy lost by the battery each day is given by:
Energy = Power x time
E = P x t
Substituting Power = I x ΔV and time t = 24 hrs, we get:
E = I x ΔV x t
I = E / (ΔV x t)
Therefore, the expression for the average current supplied to the phone is:
I = E / (ΔV x t)
Part (b) Numeric value for the current in Amperes:
Substituting the given values, we get:
I = 6 J / (2.7 V x 24 hrs)
I = 0.09375 A or 93.75 mA
Therefore, the current supplied to the phone is 93.75 milliamperes (mA) or 0.09375 Amperes (A).
