Answer:

Explanation:

We need the power equation for this which is

P = Work/time

We have everything we need to solve this (the mass of the object is extra information):

P = 6860/4

P = 1715W

In an experiment performed in a space station, a force of 60n causes an object to have an acceleration equal to 4m/s s .what is
Troyanec [42]
We Know, F = m*a
Here, F = 60N
a = 4 m/s²

Substitute their values in the equation,
60 = m*4
m = 60/4
m = 15

So, your final answer & the mass of the object would be 15 Kg

Hope this helps!

Which of the following is an illuminated object? a lightbulb a fire the Sun the Moon
Harlamova29_29 [7]
The lightbulb, the fire, and the Sun all create light from some energy source.

The Moon doesn't create light.  The parts of it that the Sun shines on
are visible, the parts of it that the Sun doesn't shine on are not visible. 

Just like a rock on the ground at night, the Moon must be illuminated
by a flashlight in order to be seen.  The Sun is the flashlight.

15) What is the frequency of a pendulum that is moving at 30 m/s with a wavelength of .35 m?
____ [38]

A pendulum is not a wave.

-- A pendulum doesn't have a 'wavelength'.

-- There's no way to define how many of its "waves" pass a point
every second.

--  Whatever you say is the speed of the pendulum, that speed
can only be true at one or two points in the pendulum's swing,
and it's different everywhere else in the swing.

-- The frequency of a pendulum depends only on the length
of the string from which it hangs.


If you take the given information and try to apply wave motion to it:

             Wave speed = (wavelength) x (frequency)

             Frequency  =  (speed) / (wavelength) ,

you would end up with

             Frequency = (30 meter/sec) / (0.35 meter) = 85.7 Hz

Have you ever seen anything that could be described as
a pendulum, swinging or even wiggling back and forth
85 times every second ? ! ?     That's pretty absurd. 

This math is not applicable to the pendulum.
