Describe how a change in resistance would affect the current in a circuit.

Physics
1 answer:
Tresset [83]3 years ago
3 0

Explanation:

The relation between potential difference, current and resistance flowing in a circuit is given by using Ohm's law. It can be given by :

V = IR

I=\dfrac{V}{R}

Resistance opposes the flow of electric current in the circuit. It means that, if resistance is more, less current will flow through the circuit.

What is the net force of an object with a mass of 90.0 and accelerating at 3.0 m/s
Ksivusya [100]

The net force is 270 N

Explanation:

We can solve this problem by using Newton's second law, which states that the net force on an object is equal to the product between its mass and its acceleration:

F=ma

where

F is the force

m is the mass

a is the acceleration

In this problem, we have

m = 90.0 kg

a=3.0 m/s^2

Substituting, we find the net force on the object:

F=(90.0)(3.0)=270 N

If you separate vector B into its components. How many components will it have? Those components will be called?
Inessa [10]

The vector B will have two components and those components will be called resultant vectors.

<h3>What is a component vector?</h3>

A component vector is a unit vector that represents a given vector in a particular direction.

A vector can be represented in x - direction and y - direction.

  • x - component of the vector = Bcosθ
  • y - component of the vector = Bsinθ

Thus, the vector B will have two components and those components will be called resultant vectors.
