<span>Magnets are created due to the uniform motion of "Electrons"
Hope this helps!</span>
I believe the correct answer from the choices listed above is option C. When a baseball is thrown straight upward, <span>its acceleration at its greatest height would be 0 m/s. This is because at max height velocity of the ball is zero which means that acceleration as well is zero. Hope this answers the question. Have a nice day.</span>
Answer:
The size of the hole will increase
Explanation:
Heat is a form of energy that depends to a great extent on the temperature of the system,when a solid is heated there will be increases in it's length,area and volume otherwise known as linear,beta and superficial expansivities respectively.When Annette increased the temperature of the ring she supplied heat to the ring that led to the expansion of the ring,what really happened was that she increased the area expansivities of the ring which is the increase in area per unit area per degree rise in temperature,at such the interior diameter of the ring increase to such an extent that the ball passes through it.
Answer:
The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left.
Explanation:
There are two objects X and Y. Mass of object X is 2M, that is moving with a speed of 
and that of object Y is M that is moving with a speed of 
.
When both of the objects collide, the magnitude of the forces F the objects exert on each other is equal to :
The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left using Newton's third law of motion. Hence, the correct option is (c).
