Newton's 1st law of motion states that <span>an object at rest stays at rest and an object in uniform motion along a straight line stays in motion unless acted upon by an unbalanced force.
This law talks about the tendency of an object to resist any change in its state of rest or uniform motion, this is called Inertia. Thus Newton's 1st law of motion is also called the Law of Inertia</span>
Answer:
Explanation:
Because the total energy available to the ball doesn't change whatsoever during its entire trip from the window to the ground,
TE = KE + PE which says that the total energy available to a system is equal to the kinetic energy of the system plus the potential energy, and that this value will not ever change (because energy cannot be created or destroyed. Sound familiar?) If the ball is being held still before it is dropped from some height off the ground, it is here that the total energy can be determined, and that total energy at this point is all potential, since the ball is not moving while someone is holding it and getting ready to drop it. The SECOND it starts to fall, the potential energy begins to be converted to kinetic. As the potential energy is losing value, the kinetic is gaining it at the same rate (again, energy doesn't just disappear; it has to go somewhere. Here, it goes from potential to kinetic a little at a time). When the ball finally hits the ground, or an INSTANT BEFORE it hits the ground, the potential energy is 0 because the height of something on the ground has a height of 0. At this instant, right before the ball hits the ground, is where the KE is the greatest. All the energy at that point has been converted from potential to kinetic.
Long story short, choice B is the one you want.
Both cats transfer energy to their surrounding environment because of radiation type of movement.
<h3>How both cats transfer energy to their surroundings when they are outside on a cold day?</h3>
A cat X and cat Y transfer energy to their surroundings due to radiation because the heat energy that is present inside them is emitted in the form of radiation.
So we can conclude that both cats transfer energy to their surrounding environment because of radiation type of movement.

The answer is - both magnetic poles</span>
<span>In the earth's southern magnetic pole, auroras are known as aurora austalis or southern lights while in the northern magnetic pole they are known as aurora borealis or northern lights.</span>
<span>They are caused by charged particles borne in solar winds that are escaping from the sun. As they approach the earth, the winds distort the earth's magnetic field which allows some particles to enter the earth's atmosphere, where they excite the gases and make them glow with spectacular display of colors.</span>
