The machine does work by exerting a force over a distance. The force exerted by the machine is called the output force, Work is defined as the product of force and displacement. The work done on the machine at the effort end is called the work in and the work done by the machine at the load end is called the work out. Hope this helps!

According to Newton's third law of motion, if you push against a wall, the wall will __________.
beks73 [17]
It would be C as the law says "<span>Formally stated, </span>Newton's third law<span> is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object."</span>

The standard wave format for any wave is _________wave. When depicting ______ wave in standard wave format, the direction of mot
Svetlanka [38]

Answer;

  • Transverse wave
  • Longitudinal wave
  • Electromagnetic wave

The standard wave format for any wave is transverse wave. When depicting longitudinal wave in standard wave format, the direction of motion must be rotated by 90 degrees. Only one of two waves is shown at a time when placing electromagnetic wave in standard wave format.

Explanation;

Transverse wave is a wave in which the vibration of particles is perpendicular with the direction of the wave motion. Longitudinal wave on the other hand are waves in which the vibration of particles is parallel to the direction of the wave motion.

Electromagnetic waves are wave which do not require a material medium for transmission, they include, radio waves, microwaves, UV light, etc. Most electromagnetic waves are transverse in nature.

An Elephant is pulled by a group of clowns across a circus. The elephant has a mass of 1000kg and the clowns are pulling with a
ycow [4]

Answer:

Acceleration = 0.2m/s²

Explanation:

Given the following data;

Mass = 1000kg

Force = 200N

To find acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

F = ma

Where;

F represents force.

m represents the mass of an object.

a represents acceleration.

Making acceleration (a) the subject, we have;

Acceleration (a) = \frac{F}{m}

Substituting into the equation;

Acceleration (a) = \frac{200}{1000}

Acceleration = 0.2m/s²
