This phenomena is referred to as metal projectile injury/effect. MRI stands for magnetic resonance imaging. As expected, your body is subjected to a magnetic field. This is a technique to look inside your body without cutting it open. Metals should not be placed anywhere near an MRI because it will cause the metals to follow the direction of the magnetic field.
As we know that range of the projectile motion is given by
here we know that range will be same for two different angles
so here we can say the two angle must be complementary angles
so the two angles must be
so it is given that one of the projection angle is 75 degree
so other angle for same range must be 90 - 75 = 15 degree
so other projection angle must be 15 degree
The exact same amount of force will be exerted but in opposite direction
Answer:
12.5 J
Explanation:
Force, F = 25 N
Distance, d = 0.5 m
The direction of force and the displacement is same.
Work is defined as the product of force in the direction of displacement and the displacement.
Work = Force x displacement x CosФ
Where, Ф be the angle between force and the displacement
Here, Ф = 0°
So, W = 25 x 0.5 x Cos0°
W = 12.5 J
