A constant velocity implies the two forces must be equal and opposite.
Friction acts horizontal to the ground, therefore we must find the force applied to the sled rope that acts horizontal to the ground.
Do this by resolving:
Force = 80cos53
The force opposing this is equal, and so also = 80cos53 = 48 N (2 sig. fig.)
Answer: B. 16
Explanation:
The given table:
x y
2.5 6.25
9.4 88.36
15.6 243.63
19.5 380.25
25.8 665.64
Here, we observed that value of y is the square value of x.
i.e.
[For example 2.5²=6.25, 9.4²=88.36, 15.6²=243.63]
Put x=4, we get

Hence, the approximate value of y for x = 4 is 16.
So, the correct option is B. 16 .
Answer:
Minerals must be solid, have an orderly atomic structure, have a recognized chemical composition, be naturally occurring and <u>inorganic in origin</u>.
Explanation:
Using the formula,

Here, d is distance, v is the velocity and t is time.
Given,
and
.
Substituting these values in above formula, we get

Thus, the distance traveled by the car is 200 miles
