Let <em>v</em> denote the initial speed of the ball. The ball's position at time <em>t</em> is given by the vector
where <em>g</em> is the acceleration due to gravity with magnitude 9.80 m/s^2.
The ball reaches the goal 13 m away at time <em>t</em> such that
at which point it attains a height of 2.44 m, so that
Newton's law of Universal Gravitation tells that Force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
As there is mass for every object, and they are separated by certain distance (from 1 cm to more than hundreds of light years), they exerts Gravitational force on each other
Hope this helps!
False because nucleus just consists proton which is positively charged and neutron which is neutral. It does not contain electron , so nucleus only can be positive charge
Geothermal energy is not always found in an area that is easily accessible. <em>(C)</em>
