Answer:
i wish i knew your answer.
Explanation:
Perspective is the evaluation or analysis of something, the way we think.
perception is a way of interpreting and understanding something.
Answer:
56.6 m/s
Explanation:
The velocity of an object accelerating at constant acceleration is given by the following SUVAT equation
where
u is the initial velocity
a is the acceleration
t is the time
For the object in the problem,
u = 0 since it starts from rest
is the acceleration
Substituting t = 12.3 s, we find the velocity at that time:
Answer:
<em>The volume is increased in a ratio of 64/27</em>
Explanation:
<u>The Volume of a Sphere
</u>
The volume of a sphere of radius r is given by:
If the radius was changed to r', the new volume would be:
Dividing the latter equation by the first one:
Simplifying:
Or, equivalently:
Since r':r = 4:3, thus:
The volume is increased in a ratio of 64/27
Answer:
0.0027 V
0.000625 V
EMF doubles
Explanation:
= Initial magnetic field = 0.2 T
= Final magnetic field = 1.4 T
t = Time taken = 1.6 s
A = Area
N = Number of turns
Induced emf is given by
Emf is 0.0027 V
= Initial area =
= Final area =
B = 0.5 T
Induced emf is given by
The new emf in the loop will be 0.000625 V (magnitude)
If the number of turns is doubled then the emf doubles as
