a 22-g ping-pong ball (which is a hollow sphere) moves at an initial speed such that, when rolling without slip up a ramp with a vertical height of 81 cm, just barely reaches the top. find the speed and the total kinetic energy the ping-pong ball started with. (hint: if it just barely reaches the top, the final speed is so close to zero you may call it zero with no error.)
Answers
The ping-pong ball started with a speed of 3.23 m/s and a total kinetic energy of 0.37 J. The final speed is zero.
We can use the conservation of energy principle to solve this problem. At the bottom of the ramp, the total energy is all in the form of kinetic energy, which is given by
KE = 0.5mv²
where m is the mass of the ball, and v is its speed. At the top of the ramp, the total energy is all in the form of potential energy, which is given by:
PE = mgh
where h is the vertical height of the ramp and g is the acceleration due to gravity.
Since the ball just barely reaches the top, its final speed can be considered zero, so all of its initial kinetic energy is converted into potential energy at the top of the ramp. Therefore, we can set the initial kinetic energy equal to the final potential energy:
0.5mv² = mgh
where m = 22 g = 0.022 kg, h = 81 cm = 0.81 m, and g = 9.81 m/s^2. Solving for v, we get
v = √(2gh) = √(2 x 9.81 m/s² x 0.81 m) ≈ 3.23 m/s
The total initial kinetic energy is
KE = 0.5mv² = 0.5 x 0.022 kg x (3.23 m/s)² ≈ 0.37 J
Therefore, the ping-pong ball started with a speed of approximately 3.23 m/s and a total kinetic energy of approximately 0.37 J.

you wake up in a spaceship feeling being pushed down to the floor. what could be the possible cause?
Answers
There could be a few possible causes for feeling pushed down to the floor while waking up in a spaceship. One possibility is: that the spaceship is experiencing a sudden acceleration or change in velocity, causing the sensation of increased gravity or g-forces.
Another possibility is that the artificial gravity system on the spaceship is malfunctioning, resulting in an increase in the force of gravity felt by the occupants.
Alternatively, the sensation could be a result of waking up in a low-gravity environment after being used to Earth's higher gravity, which can cause a feeling of heaviness or difficulty moving at first.

When light hits a surface it usually bounces off at a larger angle. True or false? Justify
Answers
Answer:That only applies to highly polished surfaces, eg mirrors.
If you take a high quality laser (ie with low divergence) and aim it at a wall, you can see the spot where the laser beam reaches the wall from anywhere with a direct line-of-sight to the spot where the laser beam reaches the wall. This due to micro imperfections on the surface of the wall. At a microscopic level, the wall surface is very rough and pointing in all directions.
As to why, a beam of light bounces of a highly polished surface, I can only surmise that it is essentially due to kinematics, ie the only force opposing the light beam is normal to the surface, hence there no forces along the reflective surface. Since there are no forces along the reflective surface, the speed component of light along the reflective surface remains unchanged. However, on the plane perpendicular to the reflective surface the, the light photons bounce off at the same speed at which the hit the reflective surface because the mass of the reflective surface is much much much larger than the mass of the photons, which means that the reflective surface won’t move at all. Since conservation of momentum requires that momentum after the collision be the same as the momentum before the collision then the only way for that to happen is if the velocity of the photon perpendicular to the reflective surface is of exactly the same magnitude but in the opposite direction. Vector resolution of the speed component of the reflected beam means that the angle of reflection must be the same as the angle of incidence.

If x increases at a rate of 2cm per second when it passes through the value x = 3cm. for what reason must vary y, when y = 1 cm for the 2xy function 2 - 3x 2y, remain constant?
Answers
The value of 2-3x²y constant as x changes with time. This means that, if x increases, the value of y must decrease so as to keep 2-3x²y constant. Therefore, 2-3x²y must remain constant as x varies with time when y=1 cm.
x increases at a rate of 2cm per second when it passes through the value x = 3cm.The function given is 2-3x²y and y=1cm. We need to find the reason why 2-3x²y must remain constant when y=1cm.
Let us start with given information. When x=3cm, it increases at a rate of 2 cm/sec. Hence the differential of x with respect to time, t is given by dx/dt = 2
Given y=1 cm and 2-3x²y= k (k is a constant) Differentiating with respect to time t, we get 0 = d/dt (2-3x²y) = -6x dx/dt y + 3x² dy /dt
Solving the above expression for dy/dt, we get:
dy/dt = 2x/3ySince y=1 cm, dy/dt = 2x/3 cm/sec
Since dy/dt is proportional to x, the value of y will vary with x in order to keep the value of 2-3x²y constant, as x changes with time. option B)
We have been given a function 2-3x²y and we need to find why it must remain constant when y=1 cm and x increases at a rate of 2cm per second when it passes through the value x = 3cm. We have differentiated the function with respect to time t and obtained the value of dy/dt.
We have observed that dy/dt is proportional to x. Hence the value of y will vary with x, in order to keep the value of 2-3x²y constant as x changes with time. This means that, if x increases, the value of y must decrease so as to keep 2-3x²y constant. Therefore, 2-3x²y must remain constant as x varies with time when y=1 cm.

The change in gravitational potential energy of a 45 kg weight that is moved from 2 m to 18 m on Earth and Moon are 7.056kJ and 1.152kJ respectively.
What is Gravitational Potential energy?
Gravitational potential energy is defined as the energy possessed by or acquired by an object due to a change in its position when it is present in a gravitational field. This can be said that gravitational potential energy is the energy which is related to the gravitational force or gravitation.
Gravitational potential energy is expressed as
U=m g h
Where, U = gravitational potential energy
m = mass
g = gravitational field
h = height
For above given example,
The change in gravitational potential energy for Earth
mass= 45kg
Difference in height \((H_2-H_1)\)= 18-2= 16m
g= \(9.8m/s^2\)
U= 45*16*9.8 = 7056J or 7.056kJ
The change in gravitational potential energy for Moon
mass= 45kg
Difference in height \((H_2-H_1)\)= 18-2= 16m
g= \(1.6m/s^2\)
U= 45*16* 1.6= 1152J or 1.152kJ
Thus, the change in gravitational potential energy of a 45 kg weight that is moved from 2 m to 18 m on Earth and Moon are 7.056kJ and 1.152kJ respectively.

The voltage difference across a charged, parallel plate capacitor with plate separation 2.0 cm is 16 V. If the voltage at the positive plate is +32 V, what is the voltage inside the capacitor 0.50 cm from the positive plate? You may assume the electric field inside the capacitor is uniform. O +24 V O +28 V O +36 V O +32 V
Answers
The voltage inside the capacitor, 0.50 cm from the positive plate, is +28 V.
In a parallel plate capacitor, the electric field between the plates is uniform and directed from the positive plate to the negative plate. The electric field intensity (E) is given by E = V/d, where V is the voltage difference between the plates and d is the separation between the plates.
In this case, the voltage difference across the capacitor is given as 16 V and the plate separation is 2.0 cm (or 0.02 m). Therefore, the electric field intensity is E = 16 V / 0.02 m = 800 V/m.
Since the electric field is uniform, the voltage decreases linearly as we move away from the positive plate. Thus, at a distance of 0.50 cm (or 0.005 m) from the positive plate, the voltage would be (32 V) - (800 V/m × 0.005 m) = 32 V - 4 V = 28 V.
Therefore, the voltage inside the capacitor, 0.50 cm from the positive plate, is +28 V.

Nitrogen is heated to 500 k in a vessel of constant volume. if it enters the vessel at 50 atm and 330 k, what pressure would it exert at the working temperature if it behaved as a perfect gas?
Answers
By ideal gas approximation, the final pressure is 75.76 atm.
We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation
P . V = n . R . T
where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.
From the question above, we know that
P1 = 50 atm
T1 = 330 K
T2 = 500 K
When the initial and final volume is the same, we can use the ratio of pressure and temperature as
P1 / P2 = T1 / T2
50 / P2 = 330 / 500
P2 = 50 x 500 / 330
