Answer:
Explanation:
Given:
U1 = 1.6 m/s
U2 = -1.1 m/s
M1 = 1850 kg
M2 = 1400 kg
V1 = 0.27 m/s
Using momentum- collision equation,
M1U1 + M2U2 = M1V1 + M2V2
1850 × 1.6 - 1400 × 1.1 = 1850 × 0.27 + 1400 × V2
1420 = 499.5 + 1400V2
V2 = 0.6575 m/s
B.
KE = 1/2 × MV^2
KEa1 + KEa2 = KEb1 + KEb2
Delta KE = KE2 - KE1
KEa1 = 2368 J
KEb1 = 847 J
KEa2 = 67.433 J
KEb2 = 302.6 J
KE1 = KEa1 + KEb1
= 3215 J
KE2 = 370.033 J
Delta KE = -2845 J.
Absorbtion consists of when light strikes on an object and bounces off.
Abs and piper have a great time and
A). The drawing looks like a ladder with 4 rungs.
One rung is a 90-volt battery.
The other 3 rungs are the 3 resistors.
b). The equivalent resistance is the reciprocal of (1/15 + 1/30 + 1/60).
That's the reciprocal of 7/60, or about 8.571... ohms.
c). I = V/R = 90 / 8.571... = 10.5 Amperes.
d). The 60-ohm resistor is connected directly across the battery.
Power = V²/R = (90²) / 60 = 135 watts. Better COOL that baby !
