Answer:
2
Explanation:
mars has a shorter year because when it revolves around the sun, it takes less time than, saturn who is millions of miles away from mars, longer. Also, mars is closer to the sun than saturn
Because if you have a large population, there is a need for more food and water, but if you don't have enough food and water to support a large population, that limits it from happening
Answer: 0.374 m/s
Explanation: The motion of a loaded spring is assumed to be of a constant acceleration, hence newton's laws of motion is applicable.
Recall from the second law of motion that
F - Fr = ma
Where F = applied force = elastic force = kx
Fr = frictional force =?
u = coefficient of kinetic friction = 0.39
m = mass of block = 2.60kg
g = acceleration due to gravity = 9.8 m/s²
k = elastic constant = 810 N/m
x = 0.0310m
Fr = umg
Fr = 0.39 × 2.60 × 9.8
Fr = 9.94.
F = kx = 810 × 0.0310m = 25.11 N
By substituting the parameters, we have that
25.11 - 9.94 = 2.60 (a)
15.17 = 2.60a
a = 15.17/ 2.60 = 5.84 m/s².
Speed of block (v) =?
Distance covered (s) = 0.0120m
Initial velocity (u) = 0
Recall that
v² = u² + 2as
v² = 2as
v² = 2 × 5.84 × 0.0120m
v² = 0.1400
v = √0.1400
v = 0.374 m/s
<span>The difference between compression and tension is that a compressing force causes an object to shorten in the direction of the force, while a tension force causes an object to lengthen in the direction of the force. Regardless of the strength of the material, compression and tension forces always cause some amount of deformation. </span>
