Answer:

Explanation:
given,
F = 14.1 i + 0 j + 5.1 k
displacement = 6 m
Assuming block is moving in x- direction
we know,
dW = F dx


![W = F[x]_0^6](https://tex.z-dn.net/?f=W%20%3D%20F%5Bx%5D_0%5E6)


hence, work done by the force is equal to 
Answer:71 dB
Explanation:
Given
sound Level 
distance 
From sound Intensity





we know Intensity 




Sound level corresponding to 



Answer:
0.958 m
Explanation:
So the total mass of the system is
M = 1.93 + 2.95 + 2.41 + 3.99 = 11.28 kg
let y be the distance from the center of mass to the origin. With the reference to the origin then we have the following equation



So the center of mass is 0.958 m from the origin
Answer:
Answer C
Explanation:
The closer two masses are, the greater the gravity force between them.
This is shown in the formula
Fg = GMm/R²
Smaller distance R means greater force Fg
Answer:
Chemical you bodily functions while you are jumping
Sound you feet hitting the ground and the jump rope smacking the ground
Mechanical is you jumping up and down and the jump rope spinning a constant direction
