Explanation:
the weight of an object is its force exerted by gravity.
on earth we take gravitational acceleration to be 9.8 m/s^2
so the weight of an object on earth is given by F = mg
hence,
F = 90 × 9.8
F = 882 Newtons (weight on earth)
gravitational acceleration on the moon is equal to 9.8/6. so, we can just use the same formula to find the weight on the moon.
F = 90 × 9.8/6
F = 147 Newtons (weight on the moon)

Answer:
Explanation:
Circuit breaker is an automatic electrical switch which cuts the power when there is surge in current.
Advantages of Circuit breaker
- They are more reliable i.e. they are not replaced frequently
- Efficient and easy to safeguard electrical appliance
Disadvantage of Circuit breaker
- They are less sensitive than fuses i.e. fuses are much faster than circuit breaker.
The answer is D
Neon has 20.0026 element more then the other
Adhesive.
Adhesive is the force of attraction between molecules of different kind. Liquid flows upward the wick because the adhesive force between the wick and the liquid is higher than cohesive forces in the liquid.
When the adhesive force between the wick and the liquid is high we have capillarity taking place. This cause the liquid to move up the wick.
