Answer:
4) C.mass
5) C. Potential Energy
Explanation:
4) Kinetic energy (KE) of an object is the energy that it possesses due to its motion. If a mass is in motion ,it has a kinetic energy .
By definition
what matters in Kinetic energy is the mass and the velocity only .
there fore the answer is
C.mass
5) Potential energy is the energy stored in an object, due to the object's position or arrangement.
By definition
in potential energy the height matters.higher the height , higher the energy
therefore the answer is
C.Potential Energy
Answer:
(d) Water has a high specific heat.
Explanation:
At night, when the temperature of earth goes down due to loss of heat , the temperature of water is lost slowly and temperature of land is lost fast because of high specific heat of water . Water loses as well as gains temperature comparatively slowly due to its high specific heat .
During daytime when earth gains heat , the temperature of land rises more rapidly than water so water appears cool even during daytime when land becomes hotter . It is also due to high heat holding capacity of water or due to high specific heat of water .
This is an example of inertia - the body keeps it's energy because there is no force applied to it. When we try to stop it's motion, it resists. A man is not rigidly attached to the bus, so he keeps moving forward, at least until he hits the front window from inside. Answer is D.
The ability of solid rock to flow is called Plasticity.
Plasticity is the deformation of a solid mateial which resulted in non reversible changes of shape in response to applied force.
Another example of plasticity is when you bend metal through a forcer force to create an art or kitchen set
1. they all come from the clouds 2.they are all formed by precipatation. hope this helps enjoyyyyyy!!!!!!!!!!!!!
