Answer:
8.85437 m/s
Explanation:
m = Mass of sphere = 5 kg
h = Vertical height = 4 m
g = Acceleration due to gravity = 9.80 m/s²
Applying conservation of energy we get
The sphere's speed when it reaches the bottom of the ramp is 8.85437 m/s
According to the Law of Universal Gravitation, the gravitational force is directly proportional to the mass, and inversely proportional to the distance. In this problem, let's assume the celestial bodies to be restricted to the planets and the Sun. Since the distance is specified, the other factor would be the mass. Among all the celestial bodies, the Sun is the most massive. So, the Sun would cause the strongest gravitational pull to the satellite.
Answer:
<em>T</em><em>h</em><em>e</em><em>r</em><em>e</em><em> </em><em>are</em><em> </em><em>t</em><em>wo hydrogen </em><em>atom</em><em> </em><em>in</em><em> </em><em>all</em><em> </em><em>the</em><em> </em><em>reactants</em><em>.</em>
- Speed is the rate of change of distance with time while velocity is the rate of change of displacement with time.
- Speed is a scalar quantity while velocity is a vector quantity.
- Speed cannot be negative but velocity can be negative.
