Answer:
Your pinball machine was built using two kinds of simple machines: a lever and an inclined plane. The lever shot the marble to the top of the box with lots of force. The inclined planes made the marble wind its way down to the bottom.
Answer:
B. its consist of waves of varying lengtu
One plate goes under another in the subduction zone. So for
the given question, the correct option is option “A”. Subduction rates are not
very high. They can be only a few centimeters per year and that is the reason
people do not feel the effect. The plates between which the shifting occurs can
either be oceanic crust or the continental crust. Mountain formations are
necessarily associated with subduction movements of plates. In such cases the
movements are huge and can result in earth quakes as well.
Answer:
I = 20 A
Explanation:
The question says that, "A load of 6,000 C is conducted through a cross section in 5 minutes. Determining-if a current is not correct, we will find the value of?"
We have,
Charge, q = 6,000 C
Time, t = 5 minutes = 300 s
We need to find the current. We know that, the charge flowing per unit time is equal to current. So,

So, the current flowing through the circuit is 20 A.
The electrostatic force between two charged objects is given by

where
k is the Coulomb's constant
q1 is the charge of the first object
q2 is the charge of the second object
r is the separation between the two objects
In our problem:



So if we plug these numbers into the equation, we can find the electrostatic force between the two objects:
