An 80 N force causes a spring to compress 0.15 m. What is the spring constant? What is the potential energy of the spring?
Anni [7]
Force = -kx
80N=0.15m * -k
K=-80/0.15=533.333. Spring constant
Energy=1/2kx^2
1/2*(-80/0.15)*80^2=Energy

If a blender is plugged into a 168 V outlet that supplies 80.8 A of current, what amount of
VladimirAG [237]

Answer:

Power = 13.5744 kilowatts

Explanation:

Power is the rate at which work is done. ... Great power means a large amount of work or energy developed in a short time. For example, when a powerful car accelerates rapidly, it does a large amount of work and consumes a large amount of fuel in a short time.

Formula for power = work/time

= IVT/T

= IV

Where I is the current

And V is the voltage

The voltage V supply = 168 v

The current A supply = 80.8 A

Power = 80.8*168

Power = 13574.4 watts

Power = 13.5744 kilowatts

What is voltage, and what is its relationship to amperage and power?
ziro4ka [17]

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
