Answer:
8) A hanging 7.5 kg object stretches a spring 1.1 m. What is the spring constant? 1 . 1 66. 82 NIMO 9) A spring has a constant of 875 N/m. What hanging mass will cause this spring to stretch 4.5 m? Iouliply then divide 875 X 4. 2- - (4 04. 7919) 10) A spring with a spring constant of 25 N/m is stretched 65 cm. What was the force used? 11) A 25 N force stretches a spring 280 cm. What was the spring constant? 12) A 75 N force stretches a spring 175 cm. What was the proportionality constant? 8) 66.82 N/m 9) 401.79 kg 10) 16.25 N 11) 8.93 N/m 12) 42.86 N/m
Explanation:
Answer:
If you know the current and voltage across the whole circuit, you can find total resistance using Ohm's Law: R = V / I.
Explanation:
The strong nuclear force is the force that holds nucleons, aka protons and neutrons in the nucleus together, through the boson called the gluon. It also holds quarks together, which constitutes the protons and neutrons.
Answer:
Average speed: approximately 
.
Average velocity: approximately 
(to the north.)
Explanation:
Consider an object that travelled along a certain path. Distance travelled would be equal to the length of the entire path.
In contrast, the magnitude of displacement is equal to distance between where the object started and where it stopped.
In this question, the path George took required him to travel 
in total. Hence, the distance George travelled would be 
. However, since George stopped at a point 
to the north of where he started, his displacement would be only 
to the north.
Divide total distance by total time to find the average speed.
Divide total displacement by total time to find average velocity.
The total time of travel in this question is 
.. Therefore:
.
.
