Key idea is equating gravitational force between planet and star (right hand side) with the centripetal force necessary to maintain the orbit (left hand side):(mv2)/r = (GMm)/r2
Within the central swell of the galaxy, we can see that the orbital velocity increases almost linearly with distance, which corresponds with the formula for orbital velocity (namely that v=sqrt(GM/r)), as...
Speed and Velocity are both measures of distance travelled in a given time and are therefore calculated using Speed=Distance/Time.Speed is a scalar quantity which means that it is quantified by a magnitud...
Divide pressure by temperature to get the constant = 1150. Making sure all values are in the correct units.Then multiply by 300K to get the increased pressure. 3.45 x 10^5 Pa
The Rutherford experiment allowed us to experimentally disprove older models of the atom, forming the basis of the evidence for the nuclear model of the atom. The atom at the time was bel...
