In an atom, the mass is concentrated in the nucleus which is at the centre of the atom. The nucleus is composed of neutrons and protons, each with a relative mass of 1. By comparison, the third component ...
To begin with, chemical energy in the fuel is released through combustion and becomes thermal energy. This thermal energy is used to heat water which evaporates and become steam. The rising steam turns tu...
By just a quick look you might be tempted to say 30 m. However the key information is that the breaking force is the same. We can calculate the deceleration of the car when at 10m/s using the equation ...
Here, we must consider our UVAST equations of motion, and our variables.
U=?ms^(-1), V=45ms^(-1) , A=?ms^(-2), S= 300m, T=10s
Our equations of motion are:
A sequence is defined by the recurrence relation un+1 = 1/3 un + 10 with u3 = 6 . Find the value of u4 and the limit of the sequence.
To find ...
