Answer:
you divide distance traveled by the time it takes to travel that distance. average speed. If your speed changes from 10 km/h to 6 km/h, you have a(n) ... 400 km. Suppose that the average speed your dog can run is 3 m/s. ... she drives her scooter 7 kilometres north. She stops for lunch and then drives 5 kilometres south.
i rlly dunno lma.o
Explanation:
<h2>QUESTION:- Which formula below correctly states Coulomb's Law?</h2>
<h2>OPTIONS:- </h2>
<h2>ANSWER:- </h2>
F is directly proportional to the product of the charges
F is inversely proportional to the square of the distance between them
from above 2 equation:-
we get:-
To remove proportionality sign we use constant for this case we r using constant k
So your answer is :-
OPTION A.
Answer:
The coefficient of static friction between the coin and the turntable is 0.51
Explanation:
at the time of the slip:
centripetal force = frictional force
mv^2/r = x*m*980
v^2/r = 980x
x = v^2/980r
= [(120)^2]/[980*29]
= 0.51
Therefore, The coefficient of static friction between the coin and the turntable is 0.51
Answer: friction
Explanation:
Because when you rub to objects together it creates static electricity
80% from burning fossil fuels
