Answer: current = 10.25A

Explanation:

Toward = 240w

Alarm clock = 30w

Tanning bed = 720w

4 60 watts bulb = 60 * 4 = 240w

Total power = 240 + 30 + 720 + 240 = 1230w

Voltage = 120v

Recall that Power = current * voltage

1230 = current * 120

current = 1230/120 = 10.25A

PLS HELP!!! A 1200-kg whale swims horizontally to the right at a speed of 6.0 m/s. It suddenly collides directly with a stationa
Fittoniya [83]

Answer:

7200 kg.m/s

Explanation:

According the law of conservation of linear momentum, the sum of momentum before and after collision are equal.

Using this principle, the sum of initial momentum will be given as p=mv where p is momentum, m is mass and v is velocity

Initial momentum

Mass of whale*initial velocity of whale + mass of seal*initial seal velocity

Since the seal is initially stationary, its velocity is zero. By substitution and taking right direction as positive

Initial momentum will be

1200*6+(280*0)=7200 kg.m/s

Since both initial and final momentum should be equal, hence the final momentum will also be 7200 kg.m/s
