He should choose the room that’s 15 F.
-5 C = 23 F
Meaning that 15 F is below -5 C and 25 F is not.
Answer:
2070 m
Explanation:
Find the time to fall from d= 762.5 m to the ground :
d = 1/2 a t^2 shows t = 12.5 s
Horizontal distance = 166 m/s * 15.5 s = 2069.7 m =~2070 m
The elbow is considered to be a lever, which is a simple machine. Other levers apart from the elbow are jaw, ankle, knee, etc.
This means that it is false that the <span>elbow is an example of a compound machine found in the human body.</span>
Using kinematic equation s=ut + 1/2 at^2(u = initial velocity=0, s=120m, t= 6.32s), 120 = 0(t) + 1/2 a(6.32)^2. a = 120x2/(6.32)^2 = 6m/s^2.
Answer:
85 N
Explanation:
Given that crate mass = 20kg
Distance = 6m
Time = 3 seconds
Coefficient of kinetic friction = 0.3
We begin by calculating for acceleration
Which was gotten as 1.33 m/s sq
