The amount of gravitational pull an object experiences is its mass
<h3>
What is Weight ?</h3>
Weight can be define as gravitational pull an object. It is a product of mass and acceleration due to gravity. That is, W = mg. It is measured in Newton (N)
The amount of gravitational pull an object experiences is its mass and not density because the weight of an object depend on its mass and acceleration due to gravity.
W = mg
where
- g = acceleration due to gravity
Therefore, the amount of gravitational pull an object experiences is its mass

Answer:
The 60 Ohm bulb would be brighter than the 20 Ohm bulb.
Explanation:
Hi there!
Ohm's Law: 
where V is voltage, I is current and R is resistance
Power equation: 
The greater the power of a bulb, the brighter it is.
The bulbs are connected in series, meaning the the current travelling through each will be the same. Plug Ohm's law into the power equation so we just have I and R:
Because the current stays the same, the bulb with greater resistance will have greater power, hence being brighter. Therefore, the 60 Ohm bulb would be brighter than the 20 Ohm bulb.
I hope this helps!
Sum of works done is zero as both W_you and W_gravity is equal and opposite.
Explanation:
Mechanical work done by you will be positive as the force applied and displacement covered, both will be in same direction.
⇒Work done, W = F. D = Fd cosΘ
so, here, Θ= 0° = w_you = Fd
↑F mech
Book ↑displacement
↓F gravity
⇒Work done by gravity is negative
[AS Θ = 180 ]
sum of works done is zero as both W_you and W_gravity is equal and opposite.
