The number of times something happens in one second is its "frequency".
Personal income, sales, and payroll. it’s not education because that itself is payed for by taxes.
Answer:
In a circuit ,<u> VOLTAGE </u>can be said to be the "source" or the "push of electrons". This push then creates what is known as a <u> CURRENT , </u>which is the flow of electric charge through the circuit. This flow can the slowed down or restricted by <u>RESISTOR </u>, and this is also what can be harnessed in order to use electric <u>ENERGY </u>.
Explanation:
Voltage:
It is the 'push' that causes charges to move in a wire or other electrical conductor, also it is a Source input to the electric circuit.
Measured in Volts.
Current:
An electric current is the rate of flow of electric charge from a point or through a region.
Measured in Ampere.
Resistor:
Resistor is used to resist the flow of charge or to resist the current called as Resistance.
Measured in Ohms.
Electric Energy:
Electrical energy is a form of energy resulting from the flow of electric charge.
Measured in Joules.

Answer:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

Answer:
The horizontal component of the force exerted by Marcie is 25 N
Explanation:
Lets explain how to solve the question
Marcie shovels snow after a storm by exerting a force of 32 N on her
shovel at an angle of 50 degrees to the vertical
We need to find the horizontal component of the force exerted by Marci
The force direction is 50° to the vertical means
→ tan(50) = 
, where x is the horizontal component
of the force and y is vertical component
→ tan(50) = 
By comparing between the two expressions of tan(50)
→ The horizontal component is Fx = F sin(50)
→ The vertical component is Fy = F cos(50)
We need the horizontal component
→ F = 32 N
→ The horizontal component = 32 sin(50) = 24.51 N ≅ 25 N
<em></em>
<em>The horizontal component of the force exerted by Marcie is 25 N</em>
