To calculate Work we need Force and Distance or Total Change in Energy and Heat.
To calculate Power we need Current and Voltage or Voltage and Resistance.
Answer:
W= 638.1 J
Explanation:
As we know that
Work done is the area of the force and displacement diagram.
W=∫F.dx
W=Work
F=force
dx=Elemental displacement
From the diagram ,area A
A= 60 x 7.09 + 1/2 x 60 x 7.09
A= 638.1 J
So the work W
W= 638.1 J
Convergent boundaries move towards each other. They can be classified as continental-continental, or oceanic-continental.
Oceanic-Continental: Heavier oceanic plate slides under a continental plate in a process called subduction.
Continental-Continental: Tectonic plates push up against each other and often fold upwards, creating mountain ranges.
C. Planet A orbits its star faster than Planet B.
Explanation:
since Planet A is closer to the star due to its gravitational force, it will orbit its star faster than planet B
hope this helps :)
One reason is that when you have been out in the cold, your hands feet and exposed features of your face will take time to recover as the blood circulation improves and supplied warm blood to capillaries. So the relatively warm room you enter will not immediately feel warm until the blood has regained its normal circulation. Other factors are that windows are cooled from the outside and condensation forms on the inside because of moisture in the air. For this condensation to evaporate requires heat, which will be extracted from the room and the air near the windows will be cooled. The cold air will descend and form a draught at floor level and this will tend to make the room cooler.
