When released from rest: Potential energy = 100 J and Kinetic Energy would equal?

Physics
1 answer:
olga55 [171]3 years ago
5 0

Answer:

0J

Explanation:

The kinetic energy would be zero. An object just released from rest will have no kinetic energy but the potential energy will be maximum.

Kinetic energy is the energy due to the motion of a body

Potential energy is the energy due to the position of a body.

  • The kinetic energy at the start will therefore be zero
  • All the energy is stored as potential energy.

Therefore, the kinetic energy is zero

There are 120 degrees in a straight angle. true false
mixas84 [53]
That would be false.
Straight angle= 180 degrees
Obtuse angle= Above 90, and lower than 180
Acute angle= Below 90
Hope this helps! (:

The block in the diagram below is AT REST. However, the tension in the cable is not the only thing holding the block back. Stati
Vedmedyk [2.9K]

Answer:

The  tension in the rope is 229.37 N.

Explanation:

Given:

Mass of the block is, m=33.2\ kg

Coefficient of static friction is, \mu = 0.214

Angle of inclination is, \theta = 31.5°

Draw a free body diagram of the block.

From the free body diagram, consider the forces in the vertical direction perpendicular to inclined plane.

Forces acting are mg\cos \theta and normal N. Now, there is no motion in the direction perpendicular to the inclined plane. So,

N=mg\cos \theta\\N=(33.2)(9.8)\cos (31.5)\\N=277.415\ N

Consider the direction along the inclined plane.

The forces acting along the plane are mg\sin \theta and frictional force, f, down the plane and tension, T, up the plane.

Now, as the block is at rest, so net force along the plane is also zero.

T=mg\sin \theta+f\\T=mg\sin \theta +\mu N\\T= (33.2)(9.8)(\sin (31.5)+(0.214\times 277.415)\\T= 170+59.37\\T=229.37\ N

Therefore, the  tension in the rope is 229.37 N.

Which of these would have the highest temperature?<br><br> A. ice<br> B. water<br> C. water vapor
fiasKO [112]

Answer:

Water vapor

Explanation:

because water vapor is gas and gas particles move faster than solid particles (which stick together) and water particles ( with a somewhat normal movement) and the faster the particle, the hotter the substance is. With that being said C is the correct answer.
