Answer:
In order to understand all three questions one must have knowledge of rotational and transitional motion.
Explanation:
a.
Both energies could be compared by means of their motion,as Ball it self rolling and also moving linearly therefore it has combination of linear and rotational kinetic energy in the mean while block of ice just have linear kinetic energy therefore Basketball have more kinetic energy
in case of Basket ball
in case of Ice
b.
For momentum it is obvious that for basketball their is angular momentum along with linear momentum.
P = m v in case of linear momentum while
L= I w in case of angular momentum where I have rotational inertia and w is the angular velocity
their is no angular momentum in case of an ice block because it was moving in linear motion.
c.
Due to the additional angular momentum conserved in the case of basketball so it has more energy conserved as compared to ice block therefore frictional effect and ramp sloping does not hurt much motion of basketball as compared to ice blocking.
Accordingly Newton's findings, astronomy and physics have industrialized
hugely over the period. Scientists now recognize that every object in the
world has a force that draws each other and the power of the force hinge on the
mass of the object. Also, Newton's Laws of Motion offer individuals a
better understanding of what is likely concerning movement. This is very helpful,
particularly in mechanics and space travel. Generally, Newton had a
huge and permanent impact on science.
For the given portion of the diagram, the sequence will go as follows:Sedimentary rock ----> Heat and pressure ---->
metamorphic rock --->
melting ----> magma
Therefore, from the given choices, the correct choice would be:d. P represents metamorphic rocks and Q represents melting
Note: For the complete rock cycle, refer to the attached image.
Almost all rocks made of minerals, but different rocks contain different mixtures of minerals. Granite<span>, for example, consists of quartz, </span>feldspar<span>, and mica.

The answer is 1F. The gravitational force between two
objects is equal. The earth pulls on the moon with a force equivalent in
magnitude (but opposite in direction) to the force of the moon's attraction on
the earth. This does not unavoidably mean that the accelerations are similar, for
the reason that of the different masses of the objects, but for this question,
it would be the same amount of force which is F. Based on the formula: F = G
(M1M2)/r^2 (newton's law of universal gravitation)
