Answer:
The answer is 13 however make sure if they ask for a certain measurement like meter answer it by saying 13 meters.
Explanation:
This basically turns into basic algebra if you know the formula for work. The formula for work is W=F*d
Here are the variables that you know 650J=50N*d so you need d.
All you do is divide 650J by 50N and you get a total of 13 (meters since I don't know what they want you to put it in).
I am not completely sure, but I believe that it depends on the total mass of the Protons and Neutrons

btw this is a joke right cuz there ain’t no picture lol
Answer:
v = 17.15 m/s
Explanation:
given,
angle of ramp = 17.0°
length of ramp(l) = 30 m
height of the ramp =


h = 15 m
using energy of conservation





v = 17.15 m/s
speed of block reaching at the bottom = v = 17.15 m/s
