For a constant-velocity object, the average and instantaneous are the same. So the answer is no. It's like taking a running average of a string of numbers that are all the same number. The average is always the sum of the numbers divided by how many have accumulated, which will always equate to the repeated number.
Answer:
rotates faster
Explanation:
A huge rotating cloud of particles in space gravitate together to form an increasingly dense ball As it shrinks in size, the cloud rotates faster. Because Angular momentum is conserved, so when it shrinks the moment of inertia decreases, then angular speed must increase. So it rotates fast.
1.igneous rocks are formed when magma or lava cools and hardens
2. the cooling rate of the rock
Answer:
D.
Explanation:
To solve the exercise it is necessary to apply the concepts related to the Magnetic Field described by Faraday.
The magnetic field is given by the equation:
Where,
Permeability constant
d = diameter
I = Current
For the given problem we have a change in the diameter, twice that of the initial experiment, therefore we define that:
The ratio of change between the two is given by:
Therefore the correct answer is D.
