In physics, a scalar is a quantity of a one value to describe the size of a physical property, such as energy or dis...
assign each variable to a value in s = ut + 1/2at2u = 2m/s t=0.2sa=-9.81m/s2so s = (2 x 0.2) + 1/2(-9.81)(0.2)2so s =
The molecules move in random motion. Collisions of molecules with each other and with the walls are elastic (total kinetic energy stays constant). Time in contact is small compared with time between colli...
Firstly we write down all known variables: Initial speed (u)=0 m/s, Acceleration (a)=3 m/s2, Time (t)=5s. Final velocity (v)=?Therefore, the equation chosen to solve the problem would be: v=u+a...
For this problem we need to consider the strong nuclear force (SNF), and the electromagnetic force (EMF). Recall that the SNF attracts very strongly over very small distances (≈10-15m), and the...
