Answer:
in this case the weight of the vehicle does not change , consequently the friction force should not change
Explanation:
The friction force is a macroscopic manifestation of the interactions of the molecules between the two surfaces, this force in the case of solid is expressed by the relation
fr = μ N
W-N= 0
N = W
as in this case the weight of the vehicle does not change nor does the Normal one, consequently the friction force should not change
Answer:
The Soccer ball would travel the furthest then the bowling ball
Explanation:
The Soccer ball would travel the furthest then the bowling ball because heavier objects require more force. This example can be compared with us pushing a huge rock vs us pushing a small rock, of you thing about it the small rock moves easily then the huge rock and this is due to their difference in their mass.
Answer:
Heat transport from Sun to Earth is accomplished primarily by electromagnetic radiation.
Explanation:
We define radiation as the transfer of energy by particles or waves (as in this case) in a material medium or empty space.
The Sun is a star that emits radiation in the electromagnetic spectrum. Approximately 49% of it is in the near infrared part, 43% in the visible part (light), 7% in the UV part and the 1% left is a mixture of radio and gamma waves and X-rays.
Of the Sun's energy that reaches Earth around 30% is reflected by the atmosphere and the Earth, around 20% is absorbed by clouds and approximately 50% is absorbed by land and sea.
Hi there!
For projectile motion, the horizontal and vertical components are SEPARATE.
We can use the kinematic equation to solve:
dₓ = vₓt
We can rearrange to solve for vₓ:
dₓ/t = vₓ
0.31/0.22 = vₓ
vₓ = 1.4 m/s ⇒ A
