Answer:  With Hydroelectric power water is artificially stored in a high place, so it can be released and flow to a low place and through a generator. With Tidal energy the movement of water is also used to power a generator, but the flow of water is caused by the changing tides.

The correct restart is for there to be another kick off taken in this type of scenario.

This is a method of restarting play in which the ball is put on the center circle and passed by a player.

Kick offs occur at the beginning of any halves or when a goal is scored during the match which is why it's the most appropriate choice.

Explanation:

The torsional spring constant of the torsional oscillator (I = 0.25 kg · m² and T = 0.45 s) has a magnitude of 48.738 newton-meters.

The torsional spring constant indicates the resistance of the spring to an external moment. The torsional spring constant (κ), in newtons per meter, can be found by means of this formula in function of the period (T), in seconds and the moment of inertia (I), in kilograms per square meter:

[tex]\kappa = \frac{4\cdot \pi^{2}\cdot I}{T^{2}}[/tex]     (1)

If we know that I = 0.25 kg · m² and T = 0.45 s, then the torsional spring constant of the spring is:

[tex]\kappa = \frac{4\cdot \pi^{2}\cdot (0.25\,kg\cdot m^{2})}{(0.45\,s)^{2}}[/tex]

κ = 48.739 N · m

Answer:

W = M g = 150 kg * 9.81 m/s^2 = 1470 N

You were only given 3 significant figures in the question.

The weight of the box is 1471.5 N.

In science and engineering, an object's weight is defined as the force of gravity acting on the thing. Weight is sometimes described as a vector quantity in common textbooks, denoting the gravitational force acting on the item.

Given parameters:

Mass of the box, m = 150 kg.

Acceleration due to gravity, g = 9.8 m/s².

Hence, weight of the box is, W = mg = 150 kg × 9.81 m/s² =1471.5 N.

SO, weight of the  box with a mass of 150 kg on Earth is 1471.5 N.

Answer:

Actually, there is  no force (felt by the object) acting on the object.

It is similar to an  object in orbit around the earth (weightlessness)

F = M a    describes the motion of the particle where

M a = M g    where the acceleration of the particle is equal to the force of gravity acting on the particle

From an external view the only force acting on the particle is M g and it produces an acceleration of M g

There is no force felt by the freely falling body. The cause of free fall is gravitational pull. Where Acceleration is equal to the gravitational acceleration. According to Newton's Law of Gravitation , two bodies attract each other due to their masses and separation , since earth is a very big body therefore the lit body falls towards the earth . Thus the graph plotted is a straight line.

What is Newton's law of Gravitation?

"The force acting between two bodies is directly proportional to product of masses and inversely proportional to the square of the separation ."

F= G.{m_{1} . m_{2} }/r^{2}.

Hence the only force by which the object is falling is gravitational pull.

An electric meter reads 2345 kWh and 3456 kWh a month later. At $0.10/kWh, the bill for this energy consumption will be $111.1.

A kiloWatt-hour (kWh) is a unit of energy equal to one kilowatt of power for one hour.

The energy consumption will be equal to the difference between both readings.

E = 3456 kWh - 2345 kWh = 1111 kWh

The cost of electricity is $0.10/kWh.

1111 kWh × $0.10/kWh = $111.1

Answer:

In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit).

This is not something that waves do because they need a medium to travel through, while particles do not.

A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.

So we can conclude that electromagnetic waves like light do not require medium for its propagation.

The resultant wave of the different wave functions is = y1 + y2

The principle of superposition states that two waves moving through the same medium, the resultant value of the wave function is the sum of the different wave functions.

Waves superimpose by adding their disturbances,each disturbance corresponds to a force, and all the forces add.

Therefore, the resultant wave of the different wave functions is the addition of both wave functions which is = y1 + y2.

Explanation:

Australia's skin cancer rate is so high because of the climate and the weather in their area. It is also because since australia is on the bottom of the globe, the continent recieves higher UV radiation.

Thanks for the brainliest!

1.Australia has one of the highest rates of skin cancer in the world. This is due largely to our climate, the fact that many of us have fair skin that isn't really suited to such harsh conditions, our proximity to the equator (high UV levels) and our social attitudes and love for the outdoors.

2.Australia's unusually harsh sunshine results mainly from its location in the Southern Hemisphere. The elliptical orbit of the Earth places the Southern Hemisphere closer to the sun during its summer months than the Northern Hemisphere during its summer.

3.Basically, through migration, our two countries have been populated by many people with fair skin whose ancestors come from much less sunny climates. Lack of protective pigmentation leaves skin cells especially vulnerable to the DNA-damaging rays from the sun.20 Mar 2018
