Give an example in which a small force exerts a large torque. give another example in which a large force exerts a small torque.
goldenfox [79]
<span>Since the torque involves the product of force times lever arm, a small force can exert a greater torque than a larger force if the small force has a large enough lever arm.

With a large force exerts a small torque is a gate, hinged in its vertical line (axis). When pushed from a point near to the hinge, a very large amount is needed to open the gate.

A rock is lifted by a machine to a height of 10m. If it has a mass of 22 kilograms
zmey [24]

Answer:

2156J

Explanation:

Given parameters:

Height of lift  = 10m

Mass  = 22kg

Unknown:

Work done by the machine  = ?

Solution:

Work done is the force applied to move a body through a certain distance.

So;

        Work done  = Force x distance

Here;

       Work done  = mass x acceleration due to gravity x height

      Work done  = 22 x 9.8 x 10  = 2156J

Match the scenario to the type of potential energy represented.
Phantasy [73]

Explanation:

A battery sits in an iPod before the iPod is turned on      Chemical

A man at a carnival lifts a hammer high over his head

before swinging it down onto a pad.                                 Gravitational

A positively charged particle is slowly moved away

from a strong, negatively charged plate                               Electric

The string of a bow and arrow is pulled tight.                      Elastic

Energy is defined as the ability to do work. There are two main forms of energy which are:

  • Potential energy
  • Kinetic energy

Chemical energy energy is a form of potential energy produced through chemical reactions. A car battery is an electrochemical that converts chemical energy into electrical energy for use in the iPod. The battery is made up of electrodes through which electron flows in one direction and current is generated by the potential difference set up

Gravitational energy is a form of potential energy that tends to pull all bodies to the center of the earth. It is an attractive force.

Electrical energy is a form of energy produced through the flow of electric current in a body. As the positive charge moves away from the strong negative plate, an electric current is produced.

Elastic energy is a potential energy stored in elastic bodies that can be stretched and are not plastic.

An airplane is seller rates down a runway at 3.10 M/S squared 441.5 seconds from rest until finally left off the ground ,what is
sineoko [7]

Answer:

302129m

Explanation:

Using s= ut + 1/2at²

But u= 0

So

S= 1/2(3.1)(441.5)²

=302129m

Lana wanted to do an investigation to see what kind of birdseed the birds in her neighborhood like best. She purchased three of
Misha Larkins [42]

Answer:

The level of seed in each feeder

Explanation:

The independent variable is the variable which is the suspected cause of an observation, it is the variable that produce the effect observed in the dependent variable. The dependent variable is the variable that is measured

The independent variable is normally the x-value while the dependent variable is the y-value

In the question, Lana wants to find out the kind of birdseed that the neighborhood birds like (to eat) the most by feeding them different types of birdseed and measuring the level of the birdseed in the feeders at regular intervals

the independent variable is the bird seed types which Lana gives to the birds, to determine the type of bird seeds the birds like

The dependent variable is the level of the seed in the feeder which depends on the type of seeds the birds like.
