What kind of changes such as an increase/decrease in temperature or in the amount of water, landscape changes, and changes in sunlight availability, etc. that lead to adaptations?

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?
