Block A, with a mass of 6.0 kg, is sliding across a frictionless track at 65 m/s when it collides with Block B ( 9.0 kg) which i

s initially at rest . The two masses stick together and travel around a vertical loop with an unknown radius. They just barely make it around the vertical loop with an unknown radius.
a) Calculate the centrifugal force acting on the masses at the top of the loop
b) Calculate the velocity of the blocks just after the collision
c) Calculate the radius of the loop so that the blocks just barely make it
d) Calculate the normal force acting on the blocks when they reach the bottom after traveling through the loop

Two infinite plane sheets with uniform surface charge densities are placed parallel to each other with separation d. in the regi
kupik [55]

Answer:Uniform between the plates

Explanation:

Electric Field due to infinite sheet with uniform charge is given by

E=\dfrac{\sigma }{\epsilon _0}

Where \sigma=charge density

\epsilon _0=Space Permittivity

From the formula we can see that Electric field is independent of distance of the particle, so it is uniform between the plates .

Scrat [10]

Buhrs atomic model differed from ruthofords because it explained that electrons exist in specified energy levels surrounding the nucleus. This means that, Ruthoford believed that electrons can't do very much. However, Buhrs' model showed that electrons are much more powerful than anyone else believes they can be.

If an automobile had a 100%-efficient engine, transferring all of the fuel's energy to work, would the engine be warm to your to
svetlana [45]

Answer:

The engine would be warm to touch, and the exhaust gases would be at ambient temperature. The engine would not vibrate nor make any noise. None of the fuel entering the engine would go unused.

Explanation:

In this ideal engine, none of these events would happen due to the nature of the efficiency.

We can define efficiency as the ratio between the used energy and the potential generable energy in the fuel.

n=W, total/(E, available).

However, in real engines the energy generated in the combustion of the fuel transforms into heat (which heates the exhost gases, and the engine therefore transfering some of this heat to the environment). Also, there are some mechanical energy loss due to vibrations and sound, which are also energy that comes from the fuel combustion.
