Answer:
Vo (vertical) = Vo sin 30 = 30 m/s / 2 = 15 m/s
Vo (horizontal) = Vo cos 30 = .866 30 m/s = 26 m/s
Answer:
A
Explanation:if the things have the same charge they will repel makeing the ball move away form its positively charged guy = that the coil gun works.
Answer:
=−2.451 330 152 1*10^27J
Explanation:
The electric potential=the Voltage * Charge:
E = VQ
V = 1.53x10^8 V (positive, because the cloud has a higher potential)
Q = -1.60217657 x10^19 C (the charge of an electron)
E = (1.53x10^8 V )* (-1.60217657 x10^19 C)
E=−2.451 330 152 1*10^27J
The negative sign indicates that the potential energy is decreased by the movement of the electron.
Answer:
The position of the earth and moon.
Explanation:
The position of the earth and moon are the two main factors.
Hope this helps, have great day/night!
Answer:
Explanation:
We will use the equation F - f = ma, which is just a fancy way of stating Newton's 2nd Law. For us:
F = 5.20 to the right (+)
f = 3.29 to the left (-)
m = 1.05 kg. Therefore,
5.20 - 3.29 = 1.05a and
1.91 = 1.05a so
a = 1.82 m/s/s to the right
