Answer is A mark me brainliest
The line that indicates areas where the pressure is the same on a weather map is called isobar.
The term isobars refer to the lines that connect the points with same atmospheric pressure on a weather map. The distribution of the isobars is affected by many factors, such as the magnitude and the direction of the wind.
Answer:
(b) Centripetal force acts along the radius of circular path
Explanation:
Centripetal force is a force experienced by a body moving in a circular path. It is expressed mathematically ad F = mv²/r
m is the mass of the body
v is the velocity
r is the radius of the circular path
When a body moves in a circular path, work dome is zero because Centripetal force acts along the radius of circular path and the force is at right angle with the motion of body.
So.......
here,
Mass (m) = 20g
Change in Temperature (ΔT) = 29C-10C
= 19C
Specific Heat Capacity = 0.1 cal/ g C
now, plug the info. into the formula,
specific heat capacity = quantity of heat / (mass * change in temperature)
0.1 = quantity of heat / (20 * 19)
0.1 = quantiy of heat / 380
0.1 * 380 = quantity of heat
38 = quantity of heat
so the granite rock boulder absorbed 38 calories of heat energy from the sun
