Answer:
mass of a particular object remains the same where ever it is placed, the mass will remain the same whether the object is on the moon or earth, unlike weight which will change.
Weight is affected by gravity. Therefore it is dependent on gravity or directly proportional to the force of gravity.
weight = mass × gravity
The gravity on earth is much larger than the gravity on the moon. Therefore the weight of an object weighs heavier on earth than on the moon. The object when placed on the moon will have a lower weight.
The difference is that the weight of the object on the moon will be lower than the weight of the object on earth.
The similarity is that the mass of an object will remain the same, regardless if it's placed on the moon or earth.
Hope this helps.
Answer:
The heat needed to warm 25.3 g of copper from 22°C to 39°C is 165.59 Joules.
Explanation:
Where:
Q = heat absorbed or heat lost
c = specific heat of substance
m = Mass of the substance
ΔT = change in temperature of the substance
We have mass of copper = m = 25.3 g
Specific heat of copper = c = 0.385 J/g°C
ΔT = 39°C - 22°C = 17°C
Heat absorbed by the copper :
The heat needed to warm 25.3 g of copper from 22°C to 39°C is 165.59 Joules.
Answer:
A toy car has a 1.5-A current, and its resistance is 2 . How much voltage does the car require?
V
Explanation:
It’s, D. Kinetic Energy.
Explanation: Energy associated with an object’s motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy.
