Runner 2 sees Runner 1 passing him with a velocity of 17 m/s west.
Answer:
J = 8.4 kg*m/s
Explanation:
The magnitude of the impulse, J, on the ball can be calculated using the following equation:
(1)
<u>Where:</u>
F: is the force = 12000 N
t: is the time = 0.70x10⁻³ s
So, by entering the values above into equation (1) we can find the impulse on the ball:
Therefore, the impulse on the ball is 8.4 kg*m/s.
I hope it helps you!
Radio waves: they are present in radios and also walkie-talkies
Answer is: 3.33 Amperes (A)
Given:
Device 1: 12 ohms
Device 2: 4 ohms
Voltage Total: 40 V (Volts)
Solution: 40 V = V1 = V2
Voltage = IR
I1 = V1 / R1
I1 = (40 V) / (12 Ohms) = 3.334 A (Amperes)
I1 = 3.33 A
