Answer:
Diathermy and atmospheric pressure
Explanation:
When the energy from the Sun comes to the Earth, it hits first the atmosphere, but the air contained is almost unaffected by it because the molecules are not tight enough to absorb its incoming energy.
Later on, the sunlight reaches the soil, thus absorbing part of the energy and reflecting the rest. Because of this reflection, the air near to the ground begins to heat through convection and as it gains height the air pressure (thus the air molecules begin to separate more from each other) decreases and the energy transfer to them is more difficult. As a result, as you gain height, the air temperature decreases at a rate of 6.8 ºC every 1,000 meters.
Answer: c. displacement
Explanation:
Let's begin by stating clear that motion is the change of position of a body at a certain time. So, during this motion, the body will have a trajectory and a displacement.
In the specific case of the displacement, it is defined as the distance in a straight line between the initial and final position (is a vector magnitude).
Therefore:
Displacement s the the change in position relative to an initial location.
There are different forces acting on an object like nuclear force , gravitational force...plus external forces like friction and other..
net sum of all these is resultnat
Given that,
Deacelectration = -15 m/s²
Negative sign shows the declaration
Slowly speed = 25 m/s
Acceleration = 35 m/s²
Speed = 170 m/s
We need to calculate the time
Using equation of motion
Where, v = final velocity
u = initial velocity
a = acceleration
t = time
Put the value into the formula
We need to calculate the distance from the original runway
Using equation of motion
Hence, The distance from the original runway is 48.2 m.
