Answer:
2.4 m/s". 1
Explanation:
A jet with mass m = 8 x 10* kg jet accelerates down the runway for takeoff at 2.4 m/s". 1
(a) The voltage that is produced in the secondary circuit is 1,800 V.
(b) The current that flows in the secondary circuit is 1 A.
<h3>Voltage in the secondary coil</h3>
Np/Ns = Vp/Vs
where;
- Np is number of turns in primary coil
- Ns is number of turns in secondary coil
- Vp is voltage in primary coil
- Vs is voltage in secondary coil
100/1500 = 120/Vs
Vs = (120 x 1500)/100
Vs = 1,800 V
<h3>Current in the secondary coil</h3>
Is/Ip = Vp/Vs
where;
- Is is secondary current
- Ip is primary current
Is = (IpVp)/Vs
Is = (15 x 120)/1800
Is = 1 A
Thus, the voltage that is produced in the secondary circuit is 1,800 V.

By bring their legs close to their bodies, they are decreasing the length of the pendulum which help them move more quickly.
A pendulum is nothing but a body suspended from a fixed point so that it can swing back and forth under the influence of gravity.
Here in this case Gibbons are bringing their legs close to their bodies and reducing the length of the pendulum. Since as the length of the pendulum increases the speed of the movement will be reduced. By bringing their legs close to their bodies they are reducing the length and in turn their speed increase and they move quickly.

Quasar is famous for being an intergalactic object which is billions of years away from the earth yet can still be seen, unlike the other star body, unlike giant galaxies.
Hence, the fact that quasars can be detected from distances where even the biggest and most luminous galaxies cannot be seen means that "they must be intrinsically far more luminous than the brightest galaxies."
This condition, including other related evidence gotten in recent years concerning our galaxy, has shown that quasars are probably the central nuclei of very distant, very active galaxies.
The surprising thing was that quasars and active galaxies have a lot of mass in the center of the very small volume of the space.
Therefore, the surprising thing about quasars was that due to this mass and energy they are 100 times more luminous than Milky Way which means they have high recession velocity and a very large amount of red-shifting.
