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 bike would have more acceleration
Explanation:
Accourding to newtons first law a force is equal to its mass multiplied by its acceleration (f=ma) therefore an object with a higher mass compared to an object with a lower mass would experience less acceleration.
Eg.
F=50N
Motorbike M=200kg
F=ma
50=200 x a
50/200=a
0.25m/s/s =a
Bike M=35kg
F=ma
50=35 x a
50/35= a
1.43m/s/s=a
Answer: 20.2 m/s
Explanation:
From the question above, we have the following data;
M1 = 800kg
M2 = 1200kg
V1 = 13m/s
V2 = 25m/s
U (common velocity) =?
M1V1 + M2V2 = (M1 + M2). U
(800*13) + (1200*25) = (800+1200) * U
10400 + 30000 = 2000u
40400 = 2000u
U = 40400 / 2000
U = 20.2 m/s
The answer to the question is gonna be A
