Answer:
2.5 A
Explanation:
Ohms law is a physical law relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current. Mathematically, the law states that V = IR, where V is the voltage difference, I is the current in amperes, and R is the resistance in ohms. It is can easily be deduced from the foregoing that the voltage is directly proportional to current and the resistance is the constant of proportionality.
From ohm's law;
R= 6Ω
V= 15V
I= ???
V=IR
I= V/R
I= 15 V/6Ω
I= 2.5 A
Think of a car, when we have to add oil. If we didn't then the friction would cause so much heat that the engine would break and fall apart.
Give me some answer choices and i will be happy to help
Answer:
104 N
Explanation:
Calculate the spring stiffness:
F = kx
32.5 N = k (0.500 cm)
k = 65 N/cm
Find the force for the new length:
F = kx
F = (65 N/cm) (1.60 cm)
F = 104 N
