Answer:
D. 100 J
Explanation:
Given
Mass (m) = 2 kg
Height (h) = 5 m
Acceleration due to gravity (g) = 10 m/s²
Now
Work done(W)
= m * g * h
= 2 * 10 * 5
= 100 Joule
Hope it will help :)❤
10m/s - 3m/s = 7m/s
The resultant velocity is 7m/s
Answer:
The radius of the sphere is 4.05 m
Explanation:
Given;
potential at surface, 
= 450 V
potential at radial distance, 
= 150
radial distance, l = 8.1 m
Apply Coulomb's law of electrostatic force;
Therefore, the radius of the sphere is 4.05 m
Answer:
the distance between Kerala and Karnataka is 425 km.
Explanation:
Given;
speed of the train, u = 85 km/h
time taken for the train to travel from Kerala to Karnataka, t = 5 hours
The distance between Kerala and Karnataka is calculated as;
Distance = speed x time
Distance = 85 km/h x 5 h
Distance = 425 km
Therefore, the distance between Kerala and Karnataka is 425 km.
