The output winding has 1/20 as many turns as the input winding has.
So the output voltage is 1/20 of the input voltage.
That's how transformers work.
Complicated, huh !
(1/20) of 240 volts = <em>12 volts</em>
False. Bases are substances that dissociate(break down) to give off hydroxide ions in aqueous solutions. The hydroxide ions are what makes them basic.
Normal force. Normal force is always present when there is contact between two items. Normal force is counteracting the gravitational force.
Explaining the incorrect answers:
-It’s not frictional force because friction only occurs when something is moving and also making contact. While there is contact in this scenario, the apple is not moving.
-There is no applied force; that would be something like a push.
-There is a gravitational force on the table, but it doesn’t keep the apple’s push in check. They are both pointed downwards, to the earth.
Hope this helps!
Answer:
C. L
Explanation:
Given that
Displacement of the object is given as
x = A sin(2 n f t)
We know that
Quantity Dimensions
Length/Amplitude L
Distance /Displacement L
Time T
Velocity LT⁻¹
Acceleration LT⁻²
Area L²
Mass M
Frequency T⁻¹
Given that x is the displacement that is why the dimensions of the displacement will be L.
Now by balancing the dimensions both sides ,the dimensions of the A will be L.
C. L
