- (spring constant) (new length of spring - original length of spring) = Force applied to spring.
that is
-kx=F
Did you only have how far the cart traveled? No mass or acceleration or speed or time taken?
I agree the best choice is A............
The resistance (R) of the circuit is 707.1 ohms and the inductance (L) is 0.032 H.
<h3>Resistance of the circuit</h3>
For the phase constant of 45⁰, impedance is equal to the resistance of the circuit.

<h3>Resonant frequency</h3>

<h3>At driven frequency</h3>

<em>solve 1 and 2 together</em>

She can use the information of redshift of a celestial body is to find the age and distance of the object.
<h3>What is red shift?</h3>
'Red shift' is a critical idea for astronomers. The frequency of the light is increased, so the light is observed as moving towards the red side of the range.
Tabitha knows the redshift value of a particular celestial object. She uses this information to observe the consequence of the redshift.
Thus, the red shift value is used to determine the age and distance of the object.
