Total mass of the Sun = 2x10^30kg
<span>So 76% of that = (2x10^30kg)*(0.76) = 1.52x10^30kg ----> total amount of Hydrogen i</span><span>f only 12% of that is used for fusion, then (1.52x10^30kg)*(0.12) = 1.82x10^9kg</span>
Option ( c ) is correct.
Using the formula for power

P= power
i= current= 0.4 A
R= resistance= 30 ohm
so power= (0.4)² (30)
Power=4.8 W
Answer:
10044 N
Explanation:
The acceleration of the cab is calculated using the equation of motion:

<em>v</em> is the final velocity = 0 m/s in this question, since it is brought to rest
<em>u</em> is the initial velocity = 10 m/s
<em>a</em> is the acceleration
<em>s</em> is the distance = 35 m

Since it accelerates downwards, its resultant acceleration is

<em>g</em> is the acceleration of gravity.

The tension in the cable is
