Answer:
Angle of reflection of light is 34 degree
Explanation:
As per law of reflection of light we know that
angle of incidence of light = angle of reflection of light
So here we know that
angle of incidence on the surface of oil is given as

so we know that

so here we can say that reflection angle of light will be same as angle of incidence

The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.
To solve for p, plug in 750 kg for mass and 30 m/s for velocity. • is a multiplication symbol
p = mv
p = 750kg • 30m/s
p = 22500 kg•m/s
An isotope is an atom with a different number of neutrons than another atom of the same element. Since atoms of the same element all have the same number of protons, choice B(6pro &6neu vs. 6pro&7neu) is an example of isotopes
The force that pulls the wagon is the horizontal component of the actual force, which is 290*cos(32) = 246N
