Answer:
W = V Q energy = work / charge * charge
Q = I t charge = current * time
V = W / (I * t)
V = 3 * 10E8 J / (1.5 * 10E4 amps * 2 * 10E-4 sec)
V = 10^8 volts
Explanation:
The final velocity of the bale have vertical and horizontal components. So, we have:
According to conservation of energy:
Since the plane is flying due east, we have . Replacing in (1):
Now, we calculate the momentum of the bale:
From pythagoras theorem we know that:
Answer:
4050 gallons
Explanation:
In first half and hour both pumps are working property . There for it give, 45
gallons per minute . Half and hour is equal to 30 minutes.After one pump was broken only one pump is working 30 minutes .
For 1st 30 minutes ,( 2 pumps are working )
Gallons = 45 * 30 *2 = 2700 gallons
2nd 30 minutes ( 1 pump is working )
Gallons = 45*30*1 = 1350 gallons
Total gallons = 2700+1350
= 4050 gallons
Answer:
The speed is 20.70 mph.
Explanation:
Given that,
Speed = 6.7 m/s = 15 mph
In 10.4 m/s,
If 100 m record in 10.82 sec
We need to calculate the speed
Using formula of speed
Put the value into the formula
Hence, The speed is 20.70 mph.
