semiconductors ... silicon, germanium etc ...
1. <span>FX = 0 since the bottom charges are symmetrical about the y axis and the top charge is aligned with the y-axis
3. </span><span>FY > 0 since the bottom charges do not equate the top charge. The bottom charges have horizontal components which is less than q and adding them all, will not result to 3q.</span>
Answer:
two glass marbles bounce off of each other
in an elastic colission (or perfectly elastic) the 2 objects that collide usually bounce off of each other
kinetic energy before = kinetic energy after
Hello!
Here we can use PE=mgh
So with your givens we have
Mass=17kg
PE= 350J
g=9.80m/s^2
So we have
350J = 17kg * 9.80m/s^2 * h
Now we just solve for our height! So we have
350J/(17kg*9.80m/s^2) = 2.10m is the height of the shelf. So rounded to nearest whole number, the shelf is 2meters high.
Hope this help. Any questions please just ask. Thank you so much!
You can’t ask a question life this and say “(2 points)”first of all the app pickshow many points it is two that’s just disrespectful
