Answer:
Gravitational force is also decreases.
Explanation:
Gravitational force is directly proportional to the mass of an object and inversely properly to the distance between their centres. Directly means if one increases the other automatically increases or if one decreases, the other also decreases. There is a direct relationship between mass and gravitational force so if mass of the bodies decrease, the gravitational force is also decreases.
Answer:
97.5 km/h
Explanation:
The time taken by gino = 6 hours
Speed of Gino = 65 km/h
The expression for distance is :-
Distance = Speed x Time
So, The distance covered by Gino = 65 km/h x 6 hrs = 390 km
The same distance is covered by Lorry.
Time taken by Lorry is 2 hrs fewer than Gino = 4 hours
Speed = Distance/Time = 390 km/4 h = 97.5 km/h
<u>97.5 km/h is the average speed of Lorry for the whole journey.</u>
