Answer:
Mass
Explanation:
They have masses ranging from about 5 to several tens of solar masses.
Answer:
0.212V
Explanation:
The induced emf in circular loop is 
N = Number of loops = 15
A = Cross sectional Area = 
= 0.0009
dB = change in magnetic Field = 0-0.5 = -0.5
dt = time taken = 0.1sec
= 0.212V
The answer would be A because I did the math :)
Answer:
100 cc
Explanation:
Heat released in cooling human body by t degree
= mass of the body x specific heat of the body x t
Substituting the data given
Heat released by the body
= 70 x 3480 x 1
= 243600 J
Mass of water to be evaporated
= 243600 / latent heat of vaporization of water
= 243600 / 2420000
= .1 kg
= 100 g
volume of water
= mass / density
= 100 / 1
100 cc
1 / 10 litres.

Explanation:
this graph show the decrease in velocity with time
at time t=0 velocity is 40 m/sec
at time t=12sec velocity is decreases from 40 to 10 m/s
so the acceleration of the object at time=12 sec is
a=v/t
a=Δv/t
Δv=v1-v2=40-10=30 m/s
a=30/12=2.5 m/s^2
