<h2>
a) Acceleration due to gravity on the surface of the Moon is 1.64 m/s²</h2><h2>
b) Acceleration due to gravity on the surface of the Mars is 3.75 m/s²</h2>
Explanation:
a) Acceleration due to gravity
G = 6.67 × 10⁻¹¹ m² kg⁻¹ s⁻²
Mass of moon, M = 7.35 × 10²² kg
Radius of moon, r = 1.73 × 10⁶ m
Substituting
Acceleration due to gravity on the surface of the Moon is 1.64 m/s²
b) Acceleration due to gravity
G = 6.67 × 10⁻¹¹ m² kg⁻¹ s⁻²
Mass of Mars, M = 6.418 × 10²³ kg
Radius of Mars, r = 3.38 × 10⁶ m
Substituting
Acceleration due to gravity on the surface of the Mars is 3.75 m/s²
Answer:
1) A time-varying magnetic field will produce an electric field.
4) A time-varying electric field will produce a magnetic field.
Explanation:
1) A time-varying magnetic field will produce an electric field.
TRUE
time varying magnetic field will produce electric field which is given as
2) Time-varying electric and magnetic fields can propagate through space only if there is no matter in their path.
FALSE
Time varying electric field and magnetic field will induce each other and it can travel through any medium as well as it can travel without any medium also
3) Electric and magnetic fields can be treated independently only if they vary in time.
FALSE
electric field can be due to stationary charge and magnetic field due to current carrying elements so it is not compulsory to have time varying
4) A time-varying electric field will produce a magnetic field.
TRUE
Time varying electric field will produce magnetic field given as
Answer:
<h2>42.5 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 50 × 0.85
We have the final answer as
<h3>42.5 N</h3>
