Answer:
I may be a little late, but it's A i got it right on the exam
Explanation:
Answer:
180 N
Explanation:
Use Newton's second law, F = ma.
m = 4.5 kg; a = 40 m/s/s
F = (4.5)(40) = 180 N
calculate the power per hour of a radiator, knowing that it is connected to a common 110 v contact. and requires 20 Amp.
Answer:
2.2kWh
Explanation:
Given parameters:
Potential difference = 110v
Current = 20A
Unknown:
Power = ?
Solution:
To solve this problem, we use the expression below:
Power = IV
Power = 110 x 20 = 2200W
This is therefore 2.2kW
Power per hour = 2.2kWh
