<span>When still rolling your bike had kinetic energy, or energy in the form of motion. The forces resisting this motion--a mixture of many factors including air resistance, tire friction, friction in the hubs of the wheels, etc...--eventually decrease the kinetic energy of the bike to zero as it reaches a complete stop.</span>

What is the electric potential difference of 5cm from a point charge of -2.0µc

vodka [1.7K]

Answer:

V = 360 kV

Explanation:

Given that,

Charge, q = -2µC

We need to find the electric potential difference of 5cm from a point charge.

We know that the formula for the electric potential is given by :

$V=\dfrac{kq}{r}\\\\V=\dfrac{9\times 10^9\times 2\times 10^{-6}}{0.05}\\\\V=360000\ V$

$V=360\ kV$

So, the electric potential difference is 360 kV.

2.4 What is the radiation error of a temperature measurement?<br>I

Airida [17]

Answer:

diameter of the wire = 0.05 in =0.05 /12 =4.167 *10 ^-3 ft

area of cross section of the wire = A = 22/7 * ( d /2 ) ^2 =0.786 * ( 4.167 *10 ^-3 ) ^2 =1.365 *10 ^-5 ft2

E =...
