What is the system's potential energy when its kinetic energy is equal to 34e?

1 answer:

8 0

Otal energy= PEmax on the spring = KEmax of the oject
Total Energy= KE+PE at v or x not maximum. 

Using the second line 
E= 3/4 E + PE 
PE = 1/4 E 

PEmax =E = 1/2 kA^2 
PE=E/4 = (1/2)kA^2 / 4= kA^2/8

Three charges 1.5*10-6, 3*10-6, -3*10-6 are placed at three vertices of an equilateral triangle of side 30cm. Find the net force

gulaghasi [49]

Answer:

F = 0N

Explanation:

The force between two charges is given by

$F=k\frac{q_1q_2}{r^2}$

where r is the distance between the charges and K is the Coulomb's constant

(k=8-89*10^9Nm^2/C^2)

The force in the first charge is only the sum of the forces due to the other charges. Hence we have

$F_T=F_1+F_2=k\frac{q_2q_1}{r^2}+k\frac{q_3q_1}{r^2}$

$F_T=(8.89*10^9\frac{Nm^2}{C^2})\frac{(3*10^{-6}C)(1.5*10^{-6}C)}{(0.3m)^2}+(8.89*10^9\frac{Nm^2}{C^2})\frac{(-3*10^{-6}C)(1.5*10^{-6}C)}{(0.3m)^2}\\\\F_T=0.445N-0.445N=0N$

Ft=0N

Hope this helps!!

Which cars have the same magnitude of momentum? Check all that apply. car 1 car 2 car 3 car 4 car 5

wariber [46]

Answer:

Car 1 and Car 2 have the same momentum!

Explanation:

Using the formula of momentum (P=m*v), we get for each car:

Car 1: 5kg*2.2m/s = 11kg*m/s

Car 2: 5.5kg*2m/s = 11kg*m/s

Car 3: 6kg*1.35m/s = 8.1kg*m/s

Car 4: 6.5kg*1.9m/s = 12.35kg*m/s

Car 5: 7kg*1.25m/s = 8.75kg*m/s
