You and your friends are driving down the road. Your car breaks down. You have to use a 1,210 N force to push the car 201 m to t
Katyanochek1 [597]

Answer:

2.43\cdot 10^5 J

Explanation:

Since the force applied is parallel to the displacement of the car, the work done on the car is simply given by:

W=Fd

where

F = 1210 N is the force applied on the car

d = 201 m is the displacement of the car

Substituting numbers into the equation, we find:

W=(1210 N)(201 m)=2.43\cdot 10^5 J

Where is energy being applied to the system?
Aleksandr-060686 [28]
Well i cant answer the first question due to absence of diagram
For the second queation, the energy affects the Frequency of wave, the higher the ebrgy the higher the frequency. Since frequency =1/Period,energy can also be said to alter the period. Since wave speed = Frequency *Wavelength, the speed is also increase due to increase in the frequency.
its amplitude increases too by the way.

If the mass of the cement is 15 000 kg, calculate the density of this cement sample in kgm-3
MrRa [10]

Explanation:

Hi there!

Mass of the container (m) = 15000 kg

Also from the figure;

Volume of the container (V) = l*b*h

{ From figure length = 2m , breadth = 1.1m, height = 2.5m}

So,

V = (2*1.1*2.5) m³

= 5.5m³

Then;

Density (d) = m/v

= 15000/5.5

= 2727.27 kgm³

Therefore, the density is 2727.27 kgm³.

Hope it helps!
