We are given with a velocity-distance-time kinematic problem given the different times of two runners and is asked for the difference in distances the runner has ran in the track. we use the formula v= d/t where d is the distance of running, t is time and v is the velocity of the runner.
First runner,
v = d/t = 1000 m / (120+28.13s ) = 6.750826976 m/s
Second runner
Using the same velocity we determine d2.
v = d2/t2 = d2 / (120+28.48s) = 6.750826976 m/s ; d2 = 1002.362789
distance of running track is the difference of the two distance achieved by the runners, delta d= d2 - d = 2.362789 m
Changes. :) I think... Whats your question
?
Answer:
The amount of force acting on the spring.
Explanation:
Here, Fspring= kΔx is a equation denoting the amount of force acting on the spring.
where, k = spring constant.
Δx= change in the length of the spring.
so, for every Δx change in spring length, kΔx force acts on the spring.
Answer:
Planning and performing an experiment to answer the question.
Explanation:
V = 3.0 x 10⁸ m/s (This is the same for all types of electromagnetic waves)
f = 88.6 MHz = 8.86 x 10⁷ Hz
λ = ?
V = fλ
λ = V/f = (3 x 10⁸)/(8.86 x 10⁷)
= 3.4 m [Ans]
Hope this helps!
