I think it is force of acceleration but I'm not sure.. hope this helps though!
Acceleration = (change in speed) / (time for the change)
Change in speed = (speed after the change) - (speed before the change)
Change in speed = (65 m/s) - (35 m/s) = 30 m/s
Acceleration = (30 m/s) / (5 s)
<em>Acceleration = 6 m/s²</em>
Answer:
54.17volts
Explanation:
Induced emf in a coil placed in a magnetic field can be expressed as E = N¶/t where
N is the number of turns = 150turns
¶ is the magnetic flux = magnetic field strength (B) × area(A)
¶ = BA
B = 0.65T
A = 1.0m²
t is the time =1.8s
Substituting this value in the formula
E = NBA/t
E = 150×0.65×1.0/1.8
E = 54.17Volts
The induced emf in the coil is 54.17Volts
In summary, gravity is the force that creates the pressure to fuse atoms, which makes the stars shine. Eventually the temperature is high enough that the star starts fusing hydrogen into helium. When the outward pressure produced by the heating of the gas by fusion energy balances gravity, a stable star is formed.
