Answer:
20.4 miles
Explanation:
Terry's normal speed while riding his bike = 
Speed is reduced by
.
So his speed now is 
The time for which the distance needs to be found is 
Distance is given by


So, the distance traveled in 1.7 hours is 20.4 miles.
Strontium has 2 valence electrons since it is in group 2
The angular acceleration of the potter's wheel is 0.067 rad/s².
The given parameters:
- Final angular speed, ωf = 0.4 rev/s
- Time of motion, t = 37.5 s
<h3>What is angular acceleration?</h3>
- Angular acceleration of an object is the rate of change of angular speed of the object.
The angular acceleration of the potter's wheel is calculated as follows;

Thus, the angular acceleration of the potter's wheel is 0.067 rad/s².

The amount of work done during the kick is 200 Joules.
<h3>Formula for Work done </h3>
The formula for work done is Force× Distance
This is represented by fd
The force applied is 1,000 Newton
The displacement exerted by the force during kicking is 0.2meter
From this we can get the work done which is:
W= fd
= 1000N × 0.2m
= 200 Joules.

Okay, haven't done physics in years, let's see if I remember this.
So Coulomb's Law states that

so if we double the charge on

and double the distance to

we plug these into the equation to find
<span>

</span>
So we see the new force is exactly 1/2 of the old force so your answer should be

if I can remember my physics correctly.
