P=VI
Explanation:
Power is the rate at which energy is changing in a circuit. It is shown by the formulas outlined above from the group of answer choices. Since the current (I), voltage (V), and resistance (R) were mentioned in the question, any of three three formulas could be used to obtain the power drawn by the conductor.
I think the answer is Bell 4 may have either a positive or neg
The answer is 17500 J for 35*10*50 and the answer is 16500 J for 55*10*30. Thus , the first object has more gravitational potential energy
Explanation:
The concentration of salt after t minutes is given by :
A tank contains 9000 L of pure water. Brine that contains 40 g of salt per liter of water is pumped into the tank at a rate of 25 L/min.
We need to find the concentration approach at
So,
Put
Since,
C(t) = 40 g/L
So, at the concentration approaches to 40 g/L. Hence, this is the required solution.
Answer:
1.526 m
Explanation:
The motion sensor sends sound waves in air which travels at a speed of 343 m per second at 20 degree. If d be the distance of the reflecting object
total distance travelled = 2d
Time taken t = 8.9 x 10⁻³ s
velocity v = 2d / t
343 = 2 d / (8.9 x 10⁻³)
d = 1.526 m
