How high a hill can a car coast up (engine disengaged) if work done by friction is negligible and its initial speed is 128 km/h
In general, the higher the initial speed of the car and the lower the slope, the farther the car will be able to coast up, but it is impossible to give a definitive answer without variables such as the slope and mass of the car.
If the work done by friction is negligible and the car is coasting with the engine disengaged, then the only force acting on the car will be gravity. This means that the car will slow down as it goes up the hill due to the force of gravity acting against its motion. The height of the hill that the car can coast up will depend on the slope of the hill and the mass of the car, as well as the initial speed of the car and the coefficient of rolling resistance. However, it is difficult to give a precise answer without knowing the specific values of these variables.

A low-mass main-sequence star's climb up the red giant branch is halted by:
the end of hydrogen shell burning.
the beginning of helium fusion in the core.
electron-degeneracy pressure in the core.
instabilities in the star's expanding outer layers.
The ascent of a low-mass main-sequence star to the red giant branch is stopped by the beginning of helium fusion in the core.
The star starts to compress and heat up, just like when a red giant forms. In the shell, helium starts to fuse with carbon. In a shell around the helium, hydrogen fuses. The star expands once again and turns redder as a result of the burning in the shell. The aforementioned image contrasts the various evolutionary routes that low-mass stars, such as the Sun, and high-mass stars take following the red giant phase. After the helium has fused into carbon in low-mass stars (left side), the core again collapses. The star's outer layers are ejected as the core disintegrates.

At the instant that the ball rebounds, a small blob of clay of mass m is released from rest from the original height H, directly above the ball, as shown above on the right. The clay blob, which is descending, eventually collides with the ball, which is ascending. Assume that g = 10 meters/second^2, that air resistance is negligible, and that the collision process takes negligible time. Determine the speed of the ball immediately before it hits the ground. Determine the time after the release of the clay blob at which the collision takes place. Determine the height above the ground at which the collision takes place. Determine the speeds of the ball and the clay blob immediately before the collision. If the ball and the clay blob stick together on impact, what is the magnitude and direction of their velocity immediately after the collision?
i. The speed of the ball immediately before it hits the ground is 10 m/s
ii. The time after the release of the clay blob is 1 s

iv. The speeds of the ball and the clay blob immediately before the collision are 10 m/s and 20 m/s respectively
v. The magnitude and direction of their velocity is (910 + m20)/(9+m) with upward directions.
How do we determine the values of the speeds, height and magnitude?The speed of the ball immediately before it hits the ground can be determined using the equation:
v^2 = u^2 + 2as
where v is the final velocity, u is the initial velocity (0 m/s), a is the acceleration due to gravity (10 m/s^2), and s is the distance fallen (5.0 meters).
Substituting these values in gives:
v^2 = 0 + 2(10)(5) = 100
v = sqrt(100) = 10 m/s
The time after the release of the clay blob at which the collision takes place can be determined using the equation:
s = ut + (1/2)at^2
where s is the distance fallen (5.0 meters), u is the initial velocity (0 m/s), a is the acceleration due to gravity (10 m/s^2), and t is the time.
Substituting these values in gives:
5 = 0 + (1/2)(10)t^2
t = sqrt(5/5) = 1 s
The height above the ground at which the collision takes place is the same as the initial height, H = 5.0 meters.
The speeds of the ball and the clay blob immediately before the collision can be determined using the equations:
v = u + at
where v is the final velocity, u is the initial velocity (0 m/s), a is the acceleration due to gravity (10 m/s^2), and t is the time.
For the ball, t = 1 s and v = 10 m/s
For the clay blob, t = 2 s and v = 20 m/s
Since the collision is perfectly elastic, the total momentum before the collision is equal to the total momentum after the collision, and the kinetic energy before the collision is equal to the kinetic energy after the collision.
The magnitude and direction of their velocity immediately after the collision is the same as their center of mass velocity,
vcm = (m1v1+m2v2)/(m1+m2) = (910 + m20)/(9+m) and it is directed upwards.
Therefore, the correct answers are as given above.

What is concave mirror also called?
A concave mirror is also known as converging mirror because it converges the incident rays parallel to the principal axis to the focus of the mirror after reflection. Concave mirrors reflect light inward to one focal point
What is a Concave mirror ?A concave mirror has an inward-curving reflective surface that faces away from the light source. Light is reflected inward by concave mirrors to a single focus point. Unlike convex mirrors, a concave mirror's created image exhibits a variety of picture types based on the object's distance from the mirror.

What happens to the energy in a Newton's cradle demonstration? Please respond in 1-2 complete
sentences using your best grammar.
Answer:
In Newton's Cradle Demonstration, converts the potential energy of one ball into kinetic energy, which is passed down the line of other balls and results of swinging the last ball upward.
Explanation:
The balls in the middle do not swing, they do move, however, because they absorb some of the kinetic energy from the left swinging ball.
The right side exterior ball moves out but not with 100% of the kinetic energy, it receives less than 100% due to interference. However, energy is transferred from the outside left swigging ball to the opposite right end ball which then swings away.
The balls that are touching in the middle cannot conduct 100% of the kinetic energy. Then additionally, gravity affects the right side swinging ball so that the kinetic it does receive through transference is affected by gravity resistance and air resistance. Thus, it swings out with less energy momentum than the left side swinging ball had coming down.
