the answer you are looking for is the independent variable.
1 volt = 1 joule/coulomb
1 volt-coulomb = (1 joule/coulomb) · (1 coulomb) = 1 joule
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:
The basic building blocks of matter is an atom
The magnetic field at the center of the 2nd loop is half the magnetic field at the center of the 1st loop.
Explanation:
The magnetic field strength at the center of a current-carrying circular loop is
where
is the vacuum permeability
I is the current
R is the radius of the loop
For the first circular loop, we have
The second loop has
(same current)
(twice the radius)
So, the magnetic field at the centre of the second loop is
So, the magnetic field at the center of the 2nd loop is half the magnetic field at the center of the 1st loop.
