For a constant voltage, how is the resistance related to the current?

Physics

Aleksandr-060686 [28]1 year ago
8 0

Answer:

Resistance is inversely proportional to current, so when the resistance doubles, the current is cut in half. Resistance is directly proportional to current, so when the resistance doubles, the current is cut in half.

Rest and motion are relatives terms justify the statement​
Anna007 [38]

Answer:

rest and motion are the relative terms because they depend on the observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body

Calculate the kinetic energy of a 5.0kg object moving at 4.0 m/s
Nana76 [90]

Answer:

The answer is

<h2>40 J</h2>

Explanation:

The kinetic energy of an object given it's mass and velocity can be found by using the formula

KE =  \frac{1}{2} m {v}^{2}

where

m is the mass

v is the velocity

From the question

m = 5 kg

v = 4 m/s

The kinetic energy is

KE =  \frac{1}{2}  \times 5 \times  {4}^{2}  \\  =  \frac{1}{2}  \times 5 \times 16 \\  = 5 \times 8

We have the final answer as

<h3>40 J</h3>

Hope this helps you

How is the motion of an object affected when a force acts on it?
Arada [10]

Newton's first law of motion is sometimes called the law of inertia. When the forces acting on an object are balanced, the object is either at rest or moving with a constant velocity. Unbalanced forces can cause an object to accelerate or decelerate. Unbalanced forces can also cause an object to change direction.

Hope that helps!

The voltage supplied to a circuit is 17 V and the current running through is 10 A. What is the power generated?
Lelu [443]

Answer:

170 W

Explanation:

Applying

P = VI.................... Equation 1

Where P = Power generated in watt, V = Voltage supplied to the circuit, I = Current running through the circuit.

From the question,

Given: V = 17 V, I = 10 A

Substitute these values into equation 1

P = (17×10)

P = 170 Watt.

Hence the power generated is 170 W.

The right option is A. 170 W
