Answer:
The speed of galaxy relative to the earth is
Explanation:
Given :
Observed frequency
Actual frequency
For finding the speed of galaxy relative to the earth.
From the doppler effect of light,
Where , relative speed
Therefore, the speed of galaxy relative to the earth is
Answer:
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.
Explanation:
Answer:
a) 43.20V
b) 2.71W/s
c) 40.25s
d) 7.77Nm
Explanation:
(a) The emf of a rotating coil with N turns is given by:
N: turns
B: magnitude of the magnetic field
A: area
w: angular velocity
the emf max is given by:
(b) the maximum rate of change of the magnetic flux is given by:
(c)
(d) The torque is given by:
I hope this is what you are looking for
P1 = 270 kPa
V1 = 1 L
P2 = 540 kPa
V2 = ?
Use Boyle's Law:
P1V1 = P2V2
V2 = P1 V1 / P2
V2 = 270 x 1 / 540
V2 = 0.5 L
The left hemisphere of the brain controls the right side of the body.
Yes this is true statement because left brain will control the right side of the body.
so correct option will be
TRUE
