Answer:
M = 1073 Mev/c2
u = 0.95 C
Explanation:
given data:
m1 =135 Mev/c2
v1 = 0.53 c
m2 = 938 Mev/c2
v2 = 0.98 c
from conservation of momentum principle we have


...............1
Total mass of INITIAL particle M =m1+m2 = 1073 Mev/c2
using equation 1

solving for u we get
u = 0.95 C
C) studying seismic waves
AKA what is studied from earthquakes
Acceleration = speed/ time
a = Δv/Δ t
as Δv = v₂ - v₁ / t
a = 50m /s - 0 m/s / 60m
= 50m/s / 60m
= 0.834s⁻¹
Answer:
3.4 x 10^-4 T
Explanation:
A = 1.5 x 10^-3 m^2
N = 50
R = 180 ohm
q = 9.3 x 106-5 c
Let B be the magnetic field.
Initially the normal of coil is parallel to the magnetic field so the magnetic flux is maximum and then it is rotated by 90 degree, it means the normal of the coil makes an angle 90 degree with the magnetic field so the flux is zero .
Let e be the induced emf and i be the induced current
e = rate of change of magnetic flux
e = dФ / dt
i / R = B x A / t
i x t / ( A x R) = B
B = q / ( A x R)
B = (9.3 x 10^-5) / (1.5 x 10^-3 x 180) = 3.4 x 10^-4 T
Hot body will lose heat from it, and that heat will goes out from it through radiation, so it's temperature will decrease after some time.
In same manner, cold body will take the heat, and it's temperature will increase
Hope this helps!
