If an object has kinetic energy, then it also must have
a. impulse.
b. force.
c. momentum.
d. acceleration.
e. none of the above

c. momentum.

Explanation:

Kinetic energy is the energy acquired due to the motion of an objects. Kinetic energy is a scalar quantity.  It simply means it does not concern itself with direction . The formula for kinetic energy is as follow

kinetic energy = 1/2 × m × v²

where m = mass of the object

           v = velocity of the object

Momentum is said to be the amount of mass in motion. In simple expression, it is the product of the mass of a body and the velocity. Momentum is a vector quantity as it has both magnitude and direction . The formula of momentum can be represented as

momentum = m × v  

where m = mass

           v = velocity

Both kinetic energy and momentum measure a quantity that is kinematic (in motion) . so if an object has kinetic energy since it is in motion it must have momentum

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
