Answer:
a)H=84.87 m
b)R=565.27 m
Explanation:
Given that
Speed of ball on earth
U=41.2 m/s
θ=31°
We know that
Maximum height in projectile motion given as


h=22.94 m
Range in projectile motion given as


r=152.77 m
Given that on distance planet ball moves 3.7 times far more as on earth.
So on the distance planet
The maximum height ,H=3.7 h
H= 3.7 x 22.94
H=84.87 m
The range on distance planet
R=3.7 r
R=3.7 x 152.77 m
R=565.27 m
Answer:
Linear momentum= Mass*Velocity
P=mv
P=60*10
P=600Kg m/s

The strength of the magnetic field is equal to 20 Tesla.
<h3>
Explanation:</h3>
Given:
Induced potential difference = V = 12 V
Length of wire = L = 0.20 m
Speed of the moving wire = V = 3.0 m/s
Magnetic field strength = B = ?
A conductor, placed in a uniform magnetic field; when moved at a constant speed with respect to the field, leads to a changing magnetic flux, generating an electromotive force (EMF). Using, Faraday's law of magnetic induction, a moving conductor's induced EMF in terms of the magnetic field strength is given by :
......................(1)
where
E = Induced potential difference (EMF)
L = Length of the conductor
V = Speed of the conductor moved with respect to the magnetic field
B = Strength of uniform magnetic field
Rewriting equation (1) for B, we get

The strength of magnetic field is equal to 20 Tesla.
