Fc=mv2/r formula of centripetal force will be applied here with radius mass and velocity described in the above question
<h2>
Answer: False</h2>
Explanation:
Acceleration is defined as the variation of Velocity in time :
A body also has acceleration when it changes its direction. However, the rate or variation of position with time <u>is not</u> acceleration, is the definition of velocity.
Therefore the sentence is false.
Answer:
24.71 mm
Explanation:
Distance is proportional to focal length, so
d∝f
which means
Magnification of first lens
and
Similarly, magnification of second lens
and
From the above equations we get
and
which means,
and
So, we get
∴ Focal length should this camera's lens is 24.71 mm
Answer:
given,
mass of the block = m₁
mass of the another block = 3 m₁
initial Amplitude, A = 6 cm
final amplitude = 6 cm
total mechanical energy = 12 J
total energy of the block spring
A is the amplitude and k is spring constant
initial energy is equal to 12 J
from the above expression we can say that
Energy of the given system depends up on the magnitude of spring constant and the amplitude.
so, energy of both the system will be same.
we know,
It increases efficiency. Hope this helps!!!
