All we have to do is subtract
sooooo
185 - 150 = 35
so the mass of the liquid is 35g
:)
:P
:D
Answer:
Electrostatic field is a conservative field. That is work done when a charge is moved between two points is independent of path taken. Hence answer is W1
It's revolution, and no, that would be a rotation.
Answer:
v = 70 m/s
Explanation:
Range on the cannon ball is given as
![d = 500.0 m](https://tex.z-dn.net/?f=d%20%3D%20500.0%20m)
here the angle of the projection of the ball is given as 45 degree
now we know that if the velocity of the ball is "v" then its two components will be given as
![v_x = vcos45](https://tex.z-dn.net/?f=v_x%20%3D%20vcos45)
![v_y = vsin45](https://tex.z-dn.net/?f=v_y%20%3D%20vsin45)
so here time of flight of the motion is given as
![T = \frac{2v_y}{g}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B2v_y%7D%7Bg%7D)
![T = \frac{2vsin45}{g}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B2vsin45%7D%7Bg%7D)
also the range is given as
![R = v_x T](https://tex.z-dn.net/?f=R%20%3D%20v_x%20T)
![R = (vcos45)(\frac{2vsin45}{g})](https://tex.z-dn.net/?f=R%20%3D%20%28vcos45%29%28%5Cfrac%7B2vsin45%7D%7Bg%7D%29)
now plug in all data in this equation
![500.0 = \frac{v^2(2sin45cos45)}{g}](https://tex.z-dn.net/?f=500.0%20%3D%20%5Cfrac%7Bv%5E2%282sin45cos45%29%7D%7Bg%7D)
![v = 70 m/s](https://tex.z-dn.net/?f=v%20%3D%2070%20m%2Fs)
