Answer:
m = 4.65 kg
Explanation:
As we know that the mass of the water that evaporated out is given as
so the energy released in form of vapor is given as
now the heat required by remaining water to bring it from 15 degree to 100 degree
total heat required for above conversion
now by heat energy balance
heat given by granite = heat absorbed by water
You will have 2 bar magnets.
Set up a unit conversion problem, arrange units to convert minutes to seconds, then cancel all time units.
8.3 minutes x (60 seconds/1 minute) x ( 3.00x10^8 meters/1 second) = 149,400,000,000 meters
Since the time is the term with the fewest number of significant figures (2), your answer should only be expressed with two sig figs as well.
1.5x10^11 m
A)
Atmospheric pressure is 101325 Pa.
Pressure = Force / Area
Area of table = 1.5 x 2.2
= 3.3 m²
Force = 101325 x 3.3
= 334 kN
B)
According to Newton's third law, every action has an equal and opposite reaction. Thus, the upward force is equal to the force acting downward on the table and is being balanced. The force is 334 kN in the upward direction.
