Answer:
For 6.0 eV
0.5 nm, 1.45*10^6 m/s, 6.17*10^10 m/s, 1.45*10^6 m/s
For 600 eV
1.26*10^-3 nm, 2.66*10^8 m/s, 3.37*10^8 m/s, 2.66*10^8 m/s
Explanation:
See attachment for calculation
The answer is going to be 40
(a) The mechanical advantage of the ramp is determined as 2.5.
(b) The pulley provides additional advantage since it assisted the boy in pulling up the load.
<h3>
What is mechanical advantage?</h3>
The mechanical advantage of an object is the ratio of output force to input force, hence it is called force ratio.
<h3>Mechanical advantage of the ramp</h3>
M.A = Lp/h
where;
- Lp is the length of the inclined plane
- h is height of the inclined plane
M.A = 10/4
M.A = 2.5
