Explanation:

Amperage is the unit of electric current. It describes the strength of the electric current in a circuit.

The voltage is the driving force of the current in a circuit

Power is a function of voltage and current in the circuit.

Current is designate as I

Voltage as V

Power as P

I = $\frac{V}{R}$

Where R is the resistance to flow of electricity

P = I x V = $\frac{V^{2} }{R}$

The unit of power is watts and voltage is volts

Two objects of equal mass are a fixed distance apart. If the mass of each object could be tripled, the gravitational force betwe

antiseptic1488 [7]

gravitational force between two objects is given as

F = G m₁ m₂/r²

where m₁ = mass of first object , m₂ = mass of second object , r = distance between the two objects .

Initial case :

m₁ = m₂ = m

gravitational force between the objects is given as

F = G m²/r²

Final Case :

m₁ = m₂ = 3 m

new gravitational force between the objects is given as

F' = G (3m)²/r²

F' = 9 G m²/r²

F' = 9 F

hence the gravitational force between the two objects becomes 9 times.

How was the water level by rock affected by wave?<br> -Tsunami-

krok68 [10]

The answer is:

The water level by rock affected by wave as:

if the direction of the wave is going to the rock naturally by the effect of the tide which comes in, the water level will rise and increase if the wave is escaping or receding the water level will decrease and will be lower.

when the tsunami is a tidal wave which is a series of waves in a water body caused by the displacement of a large volume of water.

Kipish [7]

Answer:

Velocity

Explanation:

"The principle is that the slope of the line on a position-time graph is equal to the velocity of the object. If the object is moving with a velocity of +4 m/s, then the slope of the line will be +4 m/s."
