Answer:

The various kinds of forces that exist in the items below are:

Spring = Spring Force

Magnet = Magnetic Force

Electric Scale = Electric Force

Newton Metre = Spring Force

Explanation:

Spring Force:

When you fix an object unto or upon a spring, the resulting compression or stretching exerted by that object on the spring is called the Spring Force. Conversely, the object is acted upon by the force that brings back the object to its state of equilibrium of rest.

Magnetic Force:

The motion between electrically charged particles always results in magnetic force. This is the primary force that is active in electric motors and normal magnets.

Electric Force

In order to create an electric force, you'd need to charge two particles and bring them in proximity to one another. Usually, they'll either repel or attract one another. This attraction or repulsion is known as an electric force.

A pail in a water well is hoisted by means of a frictionless winch, which consists of a spool and a hand crank. When Jill turns

Katena32 [7]

Answer:

166 W

Explanation:

Power is the rate at which work is done.

$\text{Power} = \dfrac{\text{Work done}}{\text{time}}$

The work done by Jill is the product of the weight of the pail and the height it moves.

The weight is the product of the mass and acceleration of gravity, g. Taking g as 9.81 m/s², the weight is

W = (6.90 kg)(9.81 m/s²) = 67.689 N

Work done = (67.689 N)(27.0 m) = 1827.603 J

Power = (1827.603 J) ÷ (11.0 s) = 166 W

When an object like a tree is illuminated by the sun, and you are looking toward the tree, light rays leave the object _________

Dima020 [189]

Objects absorb and reflect light differently depending on their physical characteristics, such as their shape or composition. Thanks to the reflection we can see the objects. Reflection can be defined as the change of direction of a wave, which, when in contact with the separation surface between two changing means, returns to the point where it originated. When the light illuminates the object, such as the tree, the rays of light will disperse in all directions allowing observation.

The correct answer is A. From every point on the surface of the tree, and in every direction

Physicist Max Planck showed how objects like stars give off different colors based on their temperature. What color are the hott

jenyasd209 [6]

Answer:

the brightest found are Blue - White with

Explanation:

The energy emission of objects increases with their temperature, specifically Wien described the process in an expression

$\lambda_{maximum}$ T = 2,898 10⁻³

With this expression we can find the temperature of the stars by the color they emit.

Specifically the Sun has a color of 550 nm which corresponds to 5400K

bright stars have a BLUE color corresponding to 7500K

the brightest found are Blue - White with a temperature of 20000K
