Answer: A projectile is any object in which the only force is gravity
Explanation: Equations on how to calculate projectile velocity is stated below:
The initial velocity Vo being a vector quantity, has two componentsVox and Voy
V0x = V0 cos(θ)
V0y = V0 sin(θ)
The acceleration A is a also a vector with two components Axand Ay given
Ax = 0 and Ay = - g = - 9.8 m/s2
Along the x axis the acceleration is equal to 0 and therefore the velocity Vx is constant
Vx = Vocos(θ)
Along the y axis, the acceleration is uniform and equal to - g and the velocity at time t is g
Vy = Vo sin(θ) - g t
Along the x axis the velocity Vx is constant and therefore the component x of the displacement is
x = Vocos(θ) t
Along the y axis, the motion is of uniform acceleration and the y component of the displacement is
y = Vo sin(θ) t - (1/2) g t2
I think it’s speed will increase, if I understood it correctly
Answer:
Explanation:
The refractive index of a medium is given by the following formula:
where,
η = refractive index = 1.5
= angle of incidence = ?
= angle of refraction = 15°
Therefore,
The answer should be all of the above
Answer:
Magnetic dipole moment will be
Explanation:
We have given length of the cylinder , that is h = 5.51 cm = 0.051 m
And diameter of the cylinder d = 0.865 cm
So radius 
So volume of cylinder 
It is given there is uniform magnetization of 
We have to fond the dipole moment
Dipole moment is equal to 
, here M is magnetization and V is volume
So
