How do you label Time= energy • power

Physics
1 answer:
Lana71 [14]3 years ago
5 0

First of all, that equation is not correct, which may be the reason
that you're having trouble assigning units to the quantities.

Power is defined as [energy / time],  so  [Energy] = [ power x time ],
and
         [Time] = [ energy / power ].

Unit-wise, these equations are correct just as they appear here,
with no proportionality constants or conversion factors, when ...

[ Power ] = watts
[ Energy ] = joules
[ Time ] = seconds .

The sound intensity at a distance 2.00 m from a sound source is 5.00 Find the total sound energy emitted by the source in each s
notka56 [123]

Answer:

     P = 251, 3 W

Explanation:

The intensity is defined as the power emitted per unit area

           I = P / A

Since sound is distributed in all directions spherical shape, the area of ​​a sphere is

           A = 4π r²

let's clear the power and replace

         P = I A

         P = I (4π r²)

let's calculate

         P = 5.00 (4π 2²)

         P = 251, 3 W

What makes an electric charge?
scZoUnD [109]

Answer:

Most electric charge is carried by the electrons and protons within an atom. Conversely, two protons repel each other, as do two electrons. Advertisement. Protons and electrons create electric fields, which exert a force called the Coulomb force, which radiates outward in all directions.

Onur drops a basketball from a height of 10m on Mars, where the acceleration due to gravity has a magnitude of 3.7m/s2.​ We want
lbvjy [14]

Explanation:

It is given that, Onur drops a basketball from a height of 10 m on Mars, where the acceleration due to gravity has a magnitude of 3.7 m/s².

The second equation of kinematics gives the relationship between the height reached and time taken by it.

Here, the ball is droped under the action of gravity. The value of acceleration due to gravity on Mars is positive.

We want to know how many seconds the basketball is in the air before it hits the ground. So, the formula is :

\Delta x=v_ot+\dfrac{1}{2}at^2

t is time taken by the ball to hit the ground

v_o is initial speed of the ball

So, the correct option is (A).

A rubber ball that sits motionless near the edge of a tall bookshelf has no kinetic energy. However, it does have mechanical
klio [65]

It is possible because the rubber ball has mechanical energy which is equal to potential energy.

<h3>What is mechanical energy?</h3>

Mechanical energy of an object is the total energy possessed by the object, including the potential energy and the kinetic energy.

M.A = K.E + P.E

<h3>What is kinetic energy?</h3>

Kinetic energy is the energy possessed by an object due to its motion.

<h3>What is potential energy?</h3>

Potential energy is the energy possessed by an object due to its position.

When kinetic energy (K.E) = 0

M.A = P.E

Thus, it is possible because the rubber ball has mechanical energy which is equal to potential energy.
