Answer:
nothing, mass is not affected by gravitational force
Explanation:
Weight is the gravitational force a planet exerts on a mass on the surface.
It is the product of the mass of an object with the gravitational acceleration that the planet produces.
The weight is the gravitational force
where,
m = Mass of the object
g = Acceleration due to gravity = 9.81 m/s²
Mass is the property that matter has which opposes the force being applied to it. It is intrinsic to the object itself and does not change according to the gravitational force. But, the weight changes.
Answer:
A)
Explanation:
- In a series circuit, if we assume that each bulb has a resistance R, the equivalent resistance, is the sum of all the resistances, in this case, 3*R.
- The power dissipated in this resistance, can be expressed as follows:
- In the parallel circuit, the equivalent resistance, is equal to 1/3*R.
- The power dissipated in this resistance, can be expressed as follows:
- In order to take the ratio of both powers, we can divide both sides of (1) and (2) , as follows:
- The ratio of power dissipation in the parallel circuit to that in the series circuit is 9 times.
