The amount of energy needed to increase the temperature of a substance by

is given by:

where
m is the mass of the substance
Cs is the specific heat capacity of the substance

is the increase in temperature
In our problem, m=50.0 g,

(specific heat capacity of water) and

, therefore the amount of energy needed is
Answer:
The momentum will quadruple
Explanation:
Original momentum
momen = mv
now increase both
momen = 2m * 2v = <u>4</u> mv <====== the momentum has quadrupled
Answer:
The ball will be overtake superman after travelled distance 248.5 m.
Explanation:
Given that,
Speed of superman = 35 m/s
Height = 330 m
Mass of ball = 10 kg
Let the height at which they are at same position be S.
For superman,
We need to calculate the time
Using equation of motion
...(I)
For ball,

From equation (I) and (II)




Put the value into the formula


We need to calculate the distance travelled
Using formula of distance

Put the value into the formula


Hence, The ball will be overtake superman after travelled distance 248.5 m.
Answer:
they're divided in two ways extensive/intensive or physical/chemical
intensive properties do not depend on the amount of matter this includes (boiling point and color)
extensive properties depend on the amount of matter that is being measured (mass, and volume)
