Answer:
here there is also an electric attraction force
Explanation:
In the insulating bodies the charges are not mobile, so when one of the body is charged periodically or gained some electrical charges.
When the body is neutral the net number of electric charges is zero. When the loaded body touches it, it repels the charges of the same sign whereby the induced load is of a different sign and the two adhered sheets are attracted.
With this explanation it is equivalent to that of the ball and the wall, so here there is also an electric attraction force
Answer:
Explanation:
Factors which affects and impacts our environment may include water, sunlight, buildings and so many other. The factors which can touched are called the physical factors. The physical factirs include buildings, humans and so on. Other factirs which aren't physical inckide the the effects posed to the environment t by biological and chemical factirs which may include, the impacts in sunlight and Rainfall, the pH and so on.
Answer:
0.50 A
Explanation:
We can find the current from this through Ohm's Law:
V = IR
Now, in it's original form, we're only looking for Voltage. However, we can switch this formula around to find each part of it:
I = V / R <em>(current)</em>
R = V / I <em>(resistance)</em>
In this case, we'll use the formula for current:
V = 120 V
R = 240 Ω
I = ?
I = 120 / 240
<u><em>I = 0.5 A</em></u>
Kinetic energy= 1/2 m v^2
so... 1/2(1350)(12^2)
kinetic energy = 97200Joules
