A kangaroo hops 60 m to the east in 5 seconds.
The kangaroo stops at a lake for a drink
of water, then starts hopping again to
the south. Every second, the kangaroo's
velocity increases 2.5 m/s. What is the
kangaroo's acceleration after 5 seconds?
Answer:
The kangaroo's acceleration after 5 seconds is 2.5 m/s^2
Explanation:
We can solve this problem using the formula for acceleration:
a = (v_f - v_i) / t
where a is acceleration, v_f is final velocity, v_i is initial velocity, and t is time.
First, we need to find the initial velocity in the southward direction. We know that the kangaroo is initially moving eastward, so its initial velocity in the southward direction is zero.
Next, we need to find the final velocity in the southward direction after 5 seconds. We can use the formula for the velocity of an object undergoing constant acceleration:
v_f = v_i + a*t
where v_i is initial velocity, a is acceleration, and t is time.
The kangaroo starts with an initial southward velocity of zero, and its velocity increases by 2.5 m/s each second for 5 seconds, so its final southward velocity is:
v_f = 0 + 2.5 * 5 = 12.5 m/s
Now we can use the formula for acceleration to find the kangaroo's acceleration after 5 seconds:
a = (v_f - v_i) / t = (12.5 - 0) / 5 = 2.5 m/s^2
Therefore, the kangaroo's acceleration after 5 seconds is 2.5 m/s^2.
solid zinc oxide is added to hydrochloric acid to form zinc chloride in water. how many moles of zinc chloride will be produced when 112 grams of zinc oxide is used?
Number of moles of zinc chloride will be produced when 112 grams of zinc oxide used is 1.375 mol
The balanced chemical equation for the reaction between solid zinc oxide and hydrochloric acid is:
ZnO (s) + 2HCl (aq) → ZnCl2 (aq) + H2O (l)
From the balanced equation, we can see that 1 mole of ZnO reacts with 2 moles of HCl to produce 1 mole of ZnCl2 and 1 mole of H2O.
To determine the number of moles of ZnCl2 produced from 112 grams of ZnO, we need to first convert the mass of ZnO to moles using its molar mass. The molar mass of ZnO is 81.39 g/mol (65.38 g/mol for Zn and 16.00 g/mol for O), so:
moles of ZnO = mass of ZnO / molar mass of ZnO
moles of ZnO = 112 g / 81.39 g/mol
moles of ZnO = 1.375 mol

under which conditions do you expect a sample of gas to behave most ideally?A) high temperature and low pressure.B) low temperature and high pressure.C) high temperature and high pressure.D) low temperature and low pressure.
Under option A) high temperature and low pressure, the sample of gases are expected to behave like an ideal gas.
The definition of an ideal gas is a gas whose molecular volume and intermolecular forces are so small that it does not affect the behavior of the gas.
A real gas is one that disobeys the gas laws under any conventional pressure and temperature conditions. As the gas grows large and voluminous, it departs from its optimal behaviour.
At higher temperatures and lower pressures, a gas typically behaves more like an ideal gas because the potential energy from intermolecular forces is less significant compared to the kinetic energy of the particles and the size of the molecules is less significant compared to the void space between them. Hence, option A is the answer.

what is the evidence for the statement that white light is a composite of all the colors of the spectrum?
The Prism Experiment by Sir Isaac Newton is evidence that white light has all colors of the spectrum.
These experimental observations provide strong evidence for the statement that white light is a composite of all the colors of the spectrum.
One of the earliest pieces of evidence was provided by the famous scientist Sir Isaac Newton, who demonstrated that white light could be separated into its component colors using a prism. When a beam of white light is passed through a prism, the light is refracted at different angles, depending on the wavelength of the light. This causes the different colors to separate into a continuous spectrum, from red to violet.Another piece of evidence comes from the observation that when different colors of light are combined, they can produce white light. For example, when red, green, and blue light are mixed together, they produce white light. This is the basis for how color displays on televisions, computer screens, and other electronic devices work.Furthermore, it has been demonstrated that each color in the spectrum corresponds to a unique wavelength of light. This is supported by the fact that light can be analyzed using a spectrometer, which separates the different colors of light based on their wavelengths.Learn more about white light here:

Linear momentum is used to refer to a body moving on a straight path whereas angular momentum is used for a body moving on a circular path.
why does slow increase of force break top string but fast incrase of force break lower string
When a slow increase of force is applied to the lower string, the tension in the top string gradually increases due to the weight of the object it is supporting. As the tension in the top string increases, it eventually reaches a point where it can no longer handle the strain and breaks.
However, when a fast increase of force is applied, the tension in the lower string increases sharply and quickly. This sudden increase in tension is too much for the lower string to handle, causing it to snap before the top string can reach its breaking point. The top string is not subjected to the same rapid increase in tension, so it does not experience the same sudden force and is therefore able to withstand the strain for a longer period of time.

Five balls move through the air as shown in the figure . All five have the same size and shape. Air resistance is not negligible.rank in order, from largest to smallest, the magnitudes of the accelerations aa to ae . some may be equal.
The ranking of accelerations is Ball B > Ball A = Ball E > Ball C > Ball D.
The forces acting on each ball, such as gravity and air resistance, determine its acceleration.
Each ball faces resistance from the air, which is dependent on the ball's speed, the air's density, as well as its size, and form.
We can use the following observations to rank the accelerations of the balls:
All balls have the same size and shape, so they experience the same air resistance at the same speed.
Balls A and B have the same mass, but Ball B has twice the weight of Ball A.
Balls C and D have the same weight, but Ball D has twice the mass of Ball C.
Ball E has the same mass as Ball A, but it is moving upward with a speed of 20 m/s.
From these observations, we can make the following ranking:
a>B=C>D>e
Ball B experiences the largest acceleration because it has the largest force (due to its weight) relative to its mass. Balls A, C, and E have the same weight, but Ball A has the smallest mass and Ball E is moving upward, so they experience larger accelerations than Ball C. Ball D has the same weight as Ball C, but twice the mass, so it experiences a smaller acceleration due to the larger air resistance force acting on it.

Linear momentum is a physical quantity that describes the motion of an object in a straight line. It is the product of an object's mass and its velocity, and it has both magnitude and direction. The direction of the linear momentum is the same as the direction of the object's velocity. In other words, linear momentum is a vector quantity.
Angular momentum, on the other hand, is a physical quantity that describes the rotational motion of an object. It is the product of an object's moment of inertia and its angular velocity, and it also has both magnitude and direction. The direction of the angular momentum is perpendicular to the plane of rotation, and it is defined by the right-hand rule. In other words, angular momentum is also a vector quantity.
In summary, the main difference between linear momentum and angular momentum is the type of motion that they describe. Linear momentum describes the motion of an object in a straight line, while angular momentum describes the rotational motion of an object.

I use a bucket on the end of a rope to raise/lower objects into/from my treehouse. Rather than risk throwing it, I put my Mom's phone in the bottom of the bucket and lower it down. The phone has a mass of 0.18kg . Just after I start to lower the bucket and phone, the acceleration of these objects is 1.1m/s2 in the downwards direction.
What is the magnitude of the normal force exerted by the bottom of the bucket on the phone?
The magnitude of the normal force exerted by the bottom of the bucket on the phone is approximately 1.9404 N.
The normal force exerted by the bottom of the bucket on the phone is equal in magnitude but opposite in direction to the weight of the phone. We can find the weight of the phone using the formula:
weight = mass x gravitational acceleration
where the mass of the phone is 0.18 kg and the gravitational acceleration is approximately 9.8 m/s^2.
weight = 0.18 kg x 9.8 m/s^2
weight = 1.764 N
Since the bucket and phone are accelerating downward with an acceleration of 1.1 m/s^2, the net force acting on them must be:
net force = mass x acceleration
where the mass is the combined mass of the bucket and phone. We can calculate the net force as follows:
net force = (mass of bucket + mass of phone) x acceleration
net force = (m + 0.18 kg) x 1.1 m/s^2
We don't know the mass of the bucket, but we can assume it is much greater than the mass of the phone, so we can neglect the 0.18 kg term. Then we get:
net force ≈ m x 1.1 m/s^2
The normal force exerted by the bottom of the bucket on the phone is equal in magnitude but opposite in direction to the net force acting on the phone. Therefore, we can say:
normal force = net force = m x 1.1 m/s^2
Substituting the weight of the phone for m, we get:
