Answer:
Red = 126 - 57 = 69 in positive direction
Blue = Red + 12 = 81 mph
Answer:
Net charge contained in the cubeq= 3.536×10^-6C
Explanation:
Formular for total flux in a cube is given as:
Total flux= E300Acos(180) + E200Acos(0)
Where A is crossectional area
Total flux= A(E200-E300)
Total flux= q/Eo
q= Eo×total flux
q=(8.84×10^-12)×(100)^2×(100-60)
q= 3.536×10^-6C
Answer: 1.9394m/s
Explanation: m1 (mass of 3 billiard ball) = 0.16kg
U1(initial velocity of the 3 billiard ball) = 4.0m/s
M2 (mass of the cue ball) = 0.17kg
U1 (initial velocity of the cue ball) = 0m/s
Final velocities of both the cue ball and 3 billiard ball after collision = ?
According to the principle of conservation of linear momentum, total momenta before collision = total momenta after collision:
M1U1 + M2U2 = (M1+M2)V
0.16*4.0 + 0.17* 0 = (0.16 + 0.17)V
0.64 + 0 = 0.33V
V = 0.64/0.33 = 1.9394m/s
