Answer:
Uniform velocity is scalar , while variable velocity is vector
Explanation: Uniform velocity and variable velocity is that a body moving with uniform velocity has zero acceleration, while a body that is moving with variable velocity has some acceleration. Uniform velocity is the vector quantity while non-uniform or variable velocity is a scalar quantity

Answer:
Although the Earth has a lesser mass than the Sun, it is far closer to you, allowing for a stronger pull.
Explanation:
impulse = F × t
The greater the impulse exerted on something, the greater will be the change in momentum.
impulse = change in momentum
Ft = ∆(mv)
About 21c because it also depends on the weather outside
