Answer:The balloon's negative charges are attracted to the positive charges in the can, and so the can rolls toward the balloon.

Explanation:

According to the answer The average angular acceleration 1.3 rad/s^2.

Angular acceleration is the rate of change of angular velocity over time. It is a vector quantity, which means that it has both a magnitude and direction. Angular acceleration is usually measured in units of radians per second squared (rad/s2). The magnitude of angular acceleration indicates how quickly the angular velocity is changing, and its direction indicates the direction of the angular velocity change.

The average angular acceleration of the figure skater during this time interval can be calculated using the equation a = (Δω)/(Δt). Here, Δω is the change in angular speed during the interval and Δt is the length of the interval.

Therefore, the average angular acceleration = (7.7 rad/s - 3.2 rad/s) / 4.6 s = 1.3 rad/s^2.

Changes in volume and density cause a gas in the atmosphere to rise as it is heated, and as a gas rises, its temperature decreases.

As a gas is heated, the molecules that make up the gas gain energy and begin to move faster. As the molecules move faster, they collide with each other more frequently and with greater force, causing the gas to expand and its volume to increase.

As the gas expands, its density decreases, and its buoyancy increases, making it less dense than the surrounding air. When a gas is less dense than the surrounding air, it tends to rise, which is known as convection.

Therefore, As a gas rises, it experiences a decrease in temperature, this is due to the decrease in atmospheric pressure. When a gas rises, the pressure on it decreases, which causes the gas to cool down.

When trying to balance a tennis ball on the edge of a ruler, the ball can only balance when the balance point of the ball is determined.

The balance point of an object such as a tennis ball is the point where the object balances.

Even though an object's weight exerts downward pressure on each of its constituent parts, it is typically thought of as exerting a single force through the object's center of gravity or balance point.

The object's geometric center serves as its balancing point if its weight is spread evenly throughout it.

The equation that describes the vertical position y of the box as a function of the horizontal position x of the box is y = 1/2 x^2 + 0.5xt.

A crane and box are both initially at rest. At time t=0s, the crane begins to drive forward at a constant speed of 0. 5ms, while also lifting the box with an upward acceleration of 1ms2.

This equation agrees with the sketch in part (b) because it shows that the vertical position of the box increases as the horizontal position increases, as shown in the sketch. This equation also shows that the vertical position of the box increases with time at a rate of 1 m/s^2, which is the value used for the upward acceleration of the box.

The configuration with the resistors connected in series results in a higher total resistance.

A series circuit configuration is one in which the electrical components are connected end-to-end, so that the current must flow through each component before reaching the next one. This means that the current is the same through all components, and the total resistance of the circuit is equal to the sum of the individual resistances. In contrast, a parallel circuit configuration is one in which the electrical components are connected side-by-side, so that the current can flow through multiple components at the same time. This means that the voltage across all components is the same, and the total resistance of the circuit is lower than the smallest individual resistance.

Thus, wave speed is the distance covered per second as opposed to wave frequency, which is the number of cycles that occur each second.

Waves transfer energy, to sum up. The amount of energy they carry is inversely proportional to their frequency and amplitude. Both frequency and amplitude climb with increasing energy, correspondingly.

Wave frequency is the quantity of waves passing a particular place in a predetermined period of time. The hertz (Hz), which measures wave frequency in SI units, is one hertz, or one wave crossing a fixed point in one second.

  (Speed of sound at 0 degrees C is 331.3 m/s   ....I do not know where they got the incorrect value of 345 m/s at 0 °C)

2.5 s   *   340.866 m/s =  852 m away from fireworks

Answer:

  85.2 N

Explanation:

You want to know your weight if the Earth were 3 times as massive and had 5 times the present radius. Your weight is 710 N.

Your weight is proportional to the mass of the Earth and the square of the radius between your mass and the center of the Earth. The revised dimensions of the earth would multiply your weight by ...

  W = k(M/r²) = 710 N

  W' = k((3M)/(5r)²) = k(M/r²)(3/25) = (710 N)(3/25) = 82.5 N

Your weight would be 82.5 N.

The center of the mass of the block-system is moving with a velocity of 1.3 meters per second in the same direction as B.

In this case, we are provided with:

The mass of block A (M1) = 4 kg

The speed of block A (V1) = 2.0 meters per second

The mass of block B (M2) = 8 kg

The speed of block B (V2) = 3.0 meters per second

Consider that block A is moving in a positive direction while block B moving the opposite way.

To find the velocity of the center of the mass of the two block system, we can use this following formula:

[tex]V = \frac{M1V1 + M2V2}{M1+M2}[/tex]

To find the answer, simply plug in all of the information that you already have into the equation:

[tex]V = \frac{(4 kg) (2m/s) + (8kg) (-3m/s)}{4 kg + 8 kg}[/tex]

V = -1.3 m/s

Because the sign is negative, we may deduce that the center of mass of the two-block system is traveling in the same direction as B at a speed of 1.3 m/s.

Yes, mutations in the SARS-Cov2 may make the virus more deadly to humans because they are selected to make the virus superior in an adaptive way in order to form the next generations of viruses.

The evolutionary meaning of genetic mutations in viruses and organisms is based on the fact that mutation per se is not adaptive (or beneficial), deleterious or neutral, but it depends on the enviroment in which they are and how it affects the differential reproduction of the virus.

Therefore, with this data, we can see that the evolutionary meaning of genetic mutations in viruses and organisms is the fact that after emergence may be selected to enhance the adaptive features of a virus and thus also make it more deadly to humans in the case of viruses.

Complete (correct) question:

When SARS-CoV-2 replicates, mistakes can be made in some copies of its genome, giving rise to mutations. Mutations happen randomly and are a source of genetic variations, or differences, among viruses.

To find the average speed of the girl for the entire trip, we need to calculate the total distance covered and the total time taken.

Distance covered during running = speed x time = 5 m/s x 2 s = 10 m

Distance covered during walking = speed x time = 4 m/s x 3 s = 12 m

Distance covered during biking = speed x time = 10 m/s x 5 s = 50 m

Total distance covered = 10 m + 12 m + 50 m = 72 m

Total time taken = 2 s + 3 s + 5 s = 10 s

Average speed = Total distance covered / Total time taken

= 72 m / 10 s

= 7.2 m/s

The wavelength of the radio wave is 5.5 × 10³ m. If the frequency of the wave is 5.5 × 10⁴ hertz and the speed of the wave is 3.0 × 10⁸ m/sec.

The speed(v) of a wave is the product of wavelength(λ) and the frequency(η). We can understand this relation by the definition of the speed, which is the distance travelled by the object in unit time. The unit of distance is meter, also the unit of the wavelength is meter. On the other hand the unit of frequency is sec⁻¹. So,

Speed of a wave(v) = wavelength(λ) × Frequency(η)

Wavelength(λ) = speed of the wave(v)/Frequency(η)

Wavelength(λ) = (3.0 × 10⁸)/(5.5 × 10⁴)
