156 is the answer. so 156.25 is almost the same thing, you just round. It's not hard. Thank you!!!
Power is defined as
P = I*V
where I is the current and V is the voltage
Ohm's law gives us the relation betwen Voltage and current in a resistive component
V = I*R , Then
P = V² / R
We solve for R,
R = (110 V)²/ 75W = 161.33 ohms
Answer:
Explanation:
To plot the given forces of 0.8 N and 0.9 N. It is convenient to take
0.1 N as 1 unit in Graph
For example, 1 unit in the graph is 1 cm
then take 0.1 N equivalent to 1 cm
The coefficient of static friction between the puck and the surface.
In fact, that coefficient describes exactly how "hard" it is to cause the puck to start moving, if it starts from an idle condition.
