We know, work done = Force * displacement
Here, w = 12,000 J
f = 300 N
Substitute their values into the expression:
12,000 = 300 * d
d = 12,000 / 300
d = 120/3
d = 40 m
In short, Your Answer would be 40 meters

Answer:
D
Explanation:
Scientists use significant figures to avoid claiming more accuracy in a calculation than they actually know.
Hey, unfortunately it’s impossible for me to draw one for you here, but you should be able to draw it yourself pretty easily!
Answer:
An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Each atom has a center nucleus, where the protons and neutrons are densely packed together. Surrounding the nucleus are a group of orbiting electrons. And here is a picture that may assist your further :

Answer:
C) T
Explanation:
= Mass attached to an ideal spring
= Amplitude of the motion
= Time period of oscillation
= Spring constant of the spring
= Amplitude of the motion
Time period of oscillation of the mass attached to the spring is given as
So we see that the time period does not depend on the amplitude. hence the period of oscillation remains the same.
Answer:
Speed of sound inside metal is ≅ 8200 
Explanation:
Given :
Length of metal bar 
m
From general velocity equation,
Where 
speed of sound in air = 343
For finding time from above equation,
sec
Since pulses are separated by 
sec
So we take time difference,
So speed of sound in metal is,
