Answer:

a. Net force = 40 Newton.

b. Acceleration = 8m/s²

Explanation:

Given the following data;

Force on postive x-axis = 90N

Force on negative x-axis = 50N

Mass = 5kg

a. To find the net force;

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

The net force is equal to the difference between the two forces applied because they are acting in opposite directions.

Net force = 90 - 50

Net force = 40N

b. To find the acceleration;

Acceleration = net force/mass

Acceleration = 40/5

Acceleration = 8m/s²

As you read this in your chair, how fast are you moving relative to the chair? relative to the sun?
Oliga [24]
To answer this question, you need to know the definition of Relative Motion:
 The motion is relative when it depends on a reference point or referencial system. If you know the reference point, you can determine the velocity of an object.
 If you are sitting on your chair, you are not moving relative to it (Your speed is 0 km/s); but as you know, our planet moves around the Sun (Traslation Movement) with a speed of 30.0 km/s. Therefore, you are moving 30.0 km/s relative to the sun.

2) What must be connected for an electrical current to flow in a simple current?
hjlf

2) What must be connected for an electrical current to flow in a simple current?

<em>d.moving magnets,conductors, load to do work </em>

here moving magnets will work as generator and conductors is used as connectors.

5)What is the purpose of a load in a circuit?

<em>c.provide resistance to keep the voltage strong </em>

Load will provide the resistance to the circuit and help to build the voltage across it

6) What cause an electric current from a generator

<em>d.Magnets and conducting wires move near each other </em>

here when magnets move near wires then it will induce the electric current and behaves like generators

7) What do all generators have in common

<em>b.they transform mechanical into electrical energy </em>

They have magnets and rotating coils which will convert magnetic energy to electrical energy

8) How can we measure electrical current

<em>b.the pressure force is voltage;the # of electrons moving is amperes </em>

this voltage and number of electrons will help to calculate current

Suppose a ceiling fan has a mass of 7.5 kg and is 9.7 m above the ground. What is the gravitational potential energy of the ceil
EleoNora [17]

The gravitational potential energy (G.P.E) of the ceiling fan is 712.95 Joules.

<u>Given the following data:</u>

  • Mass of ceiling fan = 7.5 kg
  • Height = 0.7 m

<u>Scientific data:</u>

  • Acceleration due to gravity = 9.8 m/s^2

To calculate the gravitational potential energy (G.P.E) of the ceiling fan:

<h3>What is gravitational potential energy?</h3>

Gravitational potential energy (G.P.E) can be defined as the energy that is possessed by an object or body due to its position (height) above planet Earth.

Mathematically, gravitational potential energy (G.P.E) is given by this formula;

GPE = mgh

<u>Where:</u>

  • G.P.E is the gravitational potential energy.
  • m is the mass of an object.
  • g is the acceleration due to gravity.
  • h is the height of an object.

Substituting the given parameters into the formula, we have;

GPE = 7.5 \times 9.8 \times 9.7

GPE = 712.95 Joules.
