Its average speed, pretending that it traveled at a constant speed, is
v = s / t
= 600 m
5 x 60 s
= 2 m/s
but to be a velocity it needs a direction as well as a speed.
( Sorry. Can’t find a division line to put between the 600 m and the 5 x 60 s )
Answer:
The moon Phobos orbits Mars (m = 6.42 x 1023 kg) at a distance of 9.38 x 106 m.
When a current is established in a closed conducting loop , we use ammeter. Due to this resultant potential developed detected by voltmeter.
- When current flows through loop , it gets conducted.
- Due to this Electric field is generated . This happens due to induced magnetic field.
- The free electrons were at rest until current is there , still ammeter detects some deflection.
- This deflection is due to zero current.
- Due to magnetic field , current in coil changes.
- Mathematically,
- The presence of conducting loop is not necessary for having electric field.
i=0.63 io

Answer:
V = 3.97 m/s
Explanation:
Mass of a man, M = 85 kg
Mass of a bullet, m = 8 g = 0.008 kg
Speed of bullet, v = 410 m/s
We need to find the speed of a man in order to have the same kinetic energy as that of the bullet. Let the kinetic energy of the bullet is k. So,
Since, k = K (K is the kinetic energy of the man and Let V is the speed)
So, the speed of the man is 3.97 m/s.
