Answer:
Explanation:
velocity of projection, vo = 381 m/s
angle of projection, θ = 73.5°
The formula for the range is
R = 8067.4 m
Range in shorten by 34.1 %
So, the new range is
R' = 8067.4 - 34.1 x 8067.4/100
R' = 5316.4 m
Answer:
"The bowling ball on Earth will have a greater potential energy relative to the surface because the Earth has a much greater mass, and therefore a much stronger gravitational acceleration."
Explanation:
Potential energy acts as a result of the object placed over the Earth's surface, The object has the ability to fall because of the gravitational force. Gravitational potential energy is based on the weight of the object and also the height above the ground surface. But the elastic potential energy acts due to the shape of the object. Potential energy is related with the restoring of the forces which is the spring or the force of the gravity.
It depends on how much you can drink.
Answer:
Explanation:
F = Magnetic force = 0.018 N
B = Magnetic field = 0.03 T
L = Length of wire = 35 cm
= Angle between current and magnetic field = 
Magnetic force is given by
The magnitude of the current is .
Let current be I, charge be Q and time be t.
Here we are provided with,
I = 0.72A
t = 4s / 60s / 180s / 7s / 0.5s
We know,
I = Q/t
Case I
---------
When, t = 4s
0.72 = Q/4
Q = 0.72 * 4 = 2.88C
Case II
----------
When, t = 60s
0.72 = Q/60
Q = 0.72 * 60 = 43.2C
Case III
-----------
When, t = 180s
0.72 = Q/180
Q = 0.72 * 180 = 129.6C
Case IV
-----------
When, t = 7s
0.72 = Q/7
Q = 0.72 * 7 = 5.04C
Case V
----------
When, t = 0.5s
0.72 = Q/0.5
Q = 0.72 * 0.5 = 0.36C
