I think the correct answer form the choices listed above is option C. <span>The transfer of energy from objects with higher temperatures to objects with lower temperatures is defined as gradient transfer. If there are difference in temperature from one point and another point, then a gradient is present and heat transfer will surely happen.</span>

Explanation:
Answer:
Total speed of the insect as seen by a person standing on the side of the road is 22 m/s
Explanation:
There i a composition of velocities, since the air inside the bus is moving at the same speed as the bus, and the insect flying relative to it.
So for an observer on the side of the road, the insect is flying at a speed of :
20 m/s + 2 m/s = 22 m/s
Answer:
The elevator's velocity after 6 seconds is 3.189m/s
Explanation:
Using Newton's 2nd law:Fnet = ma
Mg - N = ma
Where m = mass
N = normal force
a = acceleration
g = acceleration due to gravity
Substituting the given values and finding acceleration
(95kg)(9.8m/s^2) - 830N = 95kg x a
a = (931 -830) / 95
a = 101/95
a = 1.063m/s^2
After 3 seconds, the weight 0f the person is equal to the actual weight of the person, thus the elevator will be moving at a constant velocity.
Using kinematic equation:
V = u + at
Where V = final velocity
U = initial velocity = 0
a = acceleration
t = time
V = 0 + 1.063 × 3
V = 3.189m/s
This velocity does not change . The elevator travels the test of the time at the same velocity. Therefore,the velocity at 6 seconds = 3.189m/s
