What is the motion of the object?
aleksley [76]

Answer:

<em>Thus, the object is accelerating to the left</em>

Explanation:

<u>The Net Force</u>

The net force is the result of adding all the forces as vectors acting on a body.

\vec F=\vec F_1+\vec F_2+...+\vec F_n

Each vector can be expressed in its rectangular components Fx and Fy, and the sum is the sum of the rectangular components separately.

Second Newton's law gives the relation between the net force and the acceleration of the body:

\vec F = m.\vec a

We can see the acceleration is a vector with the same direction as the net force.

The diagram shows two vertical forces and two horizontal forces.

The vertical forces are acting in opposite directions and with the same magnitude, thus they cancel out, leaving zero net force in the y-axis.

The horizontal forces are opposite and with different magnitudes. Since the force acting to the left (F3) has a greater magnitude than the force acting to the right (F4), there is a net force directed to the left with a magnitude of 60 N - 20 N = 40 N

Thus, the object is accelerating to the left

Which of the following are not examples of circular motion? Check all that<br> apply
CaHeK987 [17]

B.riding on a ferris wheel

E.a satellite orbiting the Earth

Explanation:

A person riding on a ferris wheel and a satellite orbiting the earth both depicts circular motion.

Circular motion is the motion of a body about a fixed axis or center.

  • The motion path of the body forms a circle around the center.
  • In circular motion, the travel path is along a circle.
  • An orbiting satellite traces out its orbit round the earth.
  • At certain times, it passes through that point over and over again.
  • This is similar to that of a ferris wheel

Other options gives other types of motion.

A refrigerator has a mass of 88 kg. What is the weight of the refrigerator?
Sonja [21]

Answer:

Explanation:

Hi there!

From the question;

Mass (m)= 88kg

Acceleration due to gravity (g)= 9.8m/s²

Then;

Weight (W) = m*g

                  = 88*9.8

                  = 862.4 N

Therefore, the weight of refrigerator is 862 N.

Answer: <u>Option A.</u>

Hope it helps!
