Answer:
the relative speed should be 40mph
Explanation:
Force is (mass × acceleration) measured in Newton
Pressure is the 'force' per unit area measured in Newton/m^2 (pascal)
Convection is the movement<span> of groups of molecules within </span>fluids<span> such as gases and liquids, including molten rock (rheid).</span>
Answer: Volcanoes and ridges are landforms that are created by the movement of tectonic plates.
Explanation:
Answer:
False
Explanation:
The steel ball and the wooden ball do not have the same force acting on them because their masses are different. But, they have the same acceleration which is the acceleration due to gravity g = 9.8 m/s².
Using the equation of motion under freefall, s = ut +1/2gt². Since u = 0,
s = 1/2gt² ⇒ t = √(2s/g)
Since. s = height is the same for both objects, they land at the same time neglecting air resistance.
