Formula for gravitational force shows it is inversely proportional to the distance between two masses squared this is similar to the electrostatic force thay changes according to the separation squared.
The difference is that gravity is proportional to the product of the two masses. Electro static force is proportional to the product of the two charges.
Answer:
4 m/s
Explanation:
Momentum is defined as:
where
m is the mass of the object
v is its velocity
For the object in this problem, we know:
p = 200 kg m/s is the momentum
m = 50 kg is the mass
Solving for the velocity, we find:
Answer:
option C
Explanation:
The correct answer is option C
When the ray of light pass from higher refractive index to lower refractive index then the light bend away from the normal.
when the refracted ray is parallel to the boundary of the medium, θ₂ = 90°
and the incident angle θ₁
so, the angle θc is known as the critical angle.
At critical angle the refracted ray becomes parallel to boundary surface.
Answer:
1.2ms⁻²
Explanation:
F = ma
12 = 10*a
12/10 = a
6/5 ms⁻² = a or 1.2 ms⁻² = a
