Answer:
<h2>
474Watts</h2>
Explanation:
Formula for calculating the average power P = IV. It is measured in watts
Given parameters
Root mean square current Irms = 3.95A
Root mean square voltage Vrms = 1.20×10²V
Required
Toaster's average power P
Using the formula above, P = Irms*Vrms
Substituting the given parameters;
P = 3.95 * 1.20×10²
P = 3.95 * 120
P = 474 Watts
Therefore the toaster's average power is 474Watts
What are the devices I don’t see any on there
Answer:
The value is
Explanation:
From the question we are told that
The mass of the external weight is
The height through which the mass drops is
The number of revolution made is
The diameter of the free moving piston is
The distance moved by the free moving piston is
The atmospheric pressure is
Generally the workdone by the external weight is mathematically represented as
=
=
Generally the workdone by the free moving piston is mathematically represented as
Here A is the cross-sectional area with value
So
=>
So
The net workdone is mathematically evaluated as
The negative sign shows that it is acting in opposite direction to
So
Answer:
Explanation:
Given,
Magnetic field
Radius
The angle between the area vector and magnetic field is 0 degree, because the direction of area vector is always perpendicular to the plane.
-- The potential energy of a 12-lb bowling ball up on the shelf
doesn't have anything to do with the temperature of the ball or
the shelf.
-- The potential energy of a jar full of gas does depend on the
temperature of the gas. The warmer it is, the greater its pressure
is, and the more work it can do if you let it out through a little hole
in the jar. If it gets hot enough, it'll have enough potential energy
to blow the jar to smithereens.
