Power = Work Done / Time taken

         Where Work Done is Joules, and Time is in Seconds, Power is in Watts

            = 2400 J / 6 seconds

            = 400 Watts

The power output is 400 Watts.

Nellie pulls on a 10kg wagon with a constant horizontal force of 30N. If there are no other horizontal forces, what is the wagon
s2008m [1.1K]

Answer:

The acceleration of the wagon is 3 m/s².

To calculate the acceleration of the wagon, we use the formula below.

Formula:

F = ma............. Equation 1

Where:

F = horizontal Force

m = mass of the wagon

a = acceleration of the wagon.

make a the subject of the equation

a = F/m.............. Equation 2

From the question,

Given:

F = 30 N

m = 10 kg

Substitute these values into equation 2

a = 30/10

a = 3 m/s²

Hence, the acceleration of the wagon is 3 m/s².

A car can go from 0.0 m/s to 100m/s in 6 seconds. What is the acceleration
Mama L [17]

Answer:

100-0 / 6 = 16.66 m/s

Explanation:

acceleration = vf-vi / time

vf= 100m/s

vi= 0 m/s

t= 6s

Select the appropriate units for each property of a wave.
IceJOKER [234]

Intensity: Decibels

Amplitude: Meters

Frequency: Hertz

<u>Explanation:</u>

The Wave is not visible to eyes and they can easily propagate through vacuum. the average power travelling at a given period of time in a space is the intensity. Decibels is the measure of intensity. it is measured in the decibel scale. The wave's strength and the intensity gives the amplitude of wave. It is measured using meters.

The wave's amplitude and the energy has a direct proportionality.  The number occurrence of wave cycles per second refers to the frequency of wave. it is measured in hertz. it is also measured as the number of cycles that occurs per second.

An object will only change its motion if a force is directly applied to it. is this a true statement?
skelet666 [1.2K]
True
<span> An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.this is newtons first law</span>

A space probe is orbiting a planet on a circular orbit of radius R and a speed v. The acceleration of the probe is a. Suppose ro
Mamont248 [21]

Answer:

acceleration in the new orbit is 8 time of acceleration of planet in old orbit

a_{new} = 8a.

Explanation:

given data:

radius of orbit = R

Speed pf planet = v

new radius = 0.5R

new speed = 2v

we know that acce;ration is given as

a = \frac{v^{2}}{R},

a_{new} =\frac{(2v)^{2}}{0.5R},

           = \frac{4v^{2}}{0.5R}

          = \frac{8 v^{2}}{R}

a_{new} = 8a.

acceleration in the new orbit is 8 time of acceleration of planet in old orbit
