State the equations of motion. b) A car travelling with the speed of 90Km/Hr is stopped after 5s when brake applied. Then find it’s. I) Deceleration II) Distance travelled after brake applied

How do you know how many valence electrons an atom has?

The flow of electrons from one atom to another is called

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
