Answer: false
Explanation: the longer the period, the less thef= frequency
Radiated away as electromagnetic radiation.
Answer:
W = 6642 J
Explanation:
Given that,
Mass of a crate, m = 67 kg
Force with which the crate is pulled, F = 738 N
It is moved 9 m across a frictionless floor
We need to find the work done in moving the crate. Let the work done is W. It is given by :
W = F d
W = 738 N × 9 m
= 6642 J
So, the work done is 6642 J.
Answer:
Answere is (D)
Explanation:
Given m1, v and m2
Total circular momentum is conserved: total circular momentum before putty coin collision is equal to total circular momentum after collision.
Let the final circular velocity of the system be V. Initial circular velocity of the putty is zero.
m1v + m2× 0 = (m1 + m2) V
V = m1v/(m1 + m2).
Answer:
Explanation:
R1= (1/6 + 1/6)rised to -1 = 3 ohm
R total = R1 + 6 = 3+ 6 = 9 ohm
