Answer:due to the kinetic energy stored in spring

Explanation:

this happen because when spring ia stretched it store kinetic energy and it has the ability to move back and forward so this happen

Due to stored kinetic energy in the spring, the mass oscillated like a pendulum.

It is given that a  mass is attached to two springs that are stretched. When Louise pushes the mass to either side and then lets it go, it oscillates back and forth resembling a pendulum.

This movement is observed because the mass if the block placed is shared between the two springs. This let the two springs to store the energy in them. This could also be given as potential energy.

When the mass is moved in the either side, the potential energy in the springs are turned into kinetic energy leading to movement of the mass. Since, the mass is help up with two springs, oscillatory movement or to and fro motion of the spring is observed.

As I'm Not % Sure I Can Say C & D don't seem Right, Leaving A & B Having Me to Think the Answer is A (Hope I'm Right Good-Luck)

Explanation:

Answer:  Mountains block the winds that bring rain clouds.

Explanation: By acting as obstacles to the flow of air masses, mountains contribute significantly to the dryness of deserts. Orographic lifting is a process that occurs when moist air is forced to ascend as it approaches a mountain range. The moisture in the air condenses and forms clouds as the air cools as it climbs. As a result, on the windward side of the mountains, the air loses a lot of its moisture as precipitation. The air has already lost a significant amount of moisture by the time it reaches the leeward side of the mountains, creating a rain shadow effect. On the leeward side of the mountains, this impact results in a dryer area that is often a desert. Consequently, the existence of mountains influences

C. Work
Joule is an SI unit (International System of Units) of Energy.

Work

Joule is the SI unit of work (J). The unit bears the name of James Prescott Joule.

The work accomplished by a force of one newton causing a displacement of one meter is known as a joule. Work is sometimes measured in newton meters (N-m).

Force applied over a distance is what we refer to as work. Examples of work include lifting a captive helium balloon and pushing something against gravity while operating a car up a hill. The mechanical manifestation of energy is work.

Work can be either positive or negative because the applied force can be either negative or positive.

The formula of work is

                       Work = Force x Distance

Explanation:

Oxygen is not a good conductor, it is brittle, and has no luster.

Answer:

Keep in mind this changes from microscope to microscope.

Explanation:

On most classroom microscopes, there will be two knobs on either side of the scope.  These will increase or decrease the height of the "stage", which is how you "focus" the microscope.  The larger knob will move the stage the most, and thus, is called the coarse focus.  The smaller knob is called the fine focus, and, you guessed it, will move the stage the least.  There are usually three "objective lenses".  Each will have a different magnification and will be listed on the lens itself.  It rotates around the "revolving nosepiece".  MAKE SURE THAT THE SLIDE IS LOWERED BEFORE ROTATING THE LENSES!!!!  If you don't you WILL break the slide and you WILL get death looks from the teacher.

On the stage, there are two clips.  They move NOT up and down, but they spin.  what you want to do is to move the slide into the clips.  They will not break if you do not bend them more than what the slide will bend them to.

The technique for focusing the microscope is really easy once you do it a few times.  After making sure that the microscope is plugged in and the light on and the slide and lens in the lowest position/magnification (!) move the coarse focus knob so that the object in the slide is just visible.  Once you do that, from there use the fine focus knob to make the object most visible.

These instructions vary slightly from model to model of microscope, but the picture below is very accurate and everything I warned you about is for all microscopes.

The piece of evidence changed thinking about the channel on Mars because it shows that the rock was formed next to flowing water as such rock formations exist on Earth and were formed by flowing water.

The geologic process that could have created the channel on Mars is water moving. We can infer from the image that water running across the terrain on Mars created channels similar to those on Earth.

We can claim that the flowing of water creates the channels on Mars because when the water runs for a long period from the same region, it takes the sediments and creates channels.

Answer: The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

Explanation:

Force is defined as the product of object's mass and acceleration.

Mathematically,

F = ma     ......(1)

or,

a = F/m      .....(2)

where,

F = Force exerted on an object = 60N

m = mass of an object = 30kg

a = acceleration of the object = ?

Putting values in above equation, we get:

a = 60 kg.m/s^2/30 kg = 2m/s^2

The acceleration of the car is 2m/s^2.

From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.

And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.

Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

A net force of 60 N north acts on an object with a mass of 30 kg , so according to Newton's second law of motion the acceleration of the object would be 2 m / s²,the amount of acceleration would decrease if the mass of the object increases.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

F =m × a

As given in the problem, a net force of 60 N north acts on an object with a mass of 30 kg.

60 = 30 × acceleration

acceleration = 60 / 30

                     = 2 m / s²

Thus, the acceleration of the object would be 2 m / s² , and the acceleration would decrease if the mass of the object increases.

Answer:

Fnew = k (-3Q *(-Q)) / (2d)²

Fnew = k * 3Q² /4d²

Explanation:

This is Coulomb's law

F = k (q₁*q₂)/r²

F - electric force

k - Coulomb constant

q₁, q₂ - charges

r - distance of charges

Starting situation :   q₁ = -Q, q₂= -Q , r =2d

F = k (-Q*(-Q)) / (2d)²

F = k *Q² /4d²

NEW FORCE :  q₁ = -3Q, q₂= -Q, r =2d

Fnew = k (-3Q *(-Q)) / (2d)²

Therefore, the mass of Betelgeuse is about 17.634 kg/ 9.5 times the mass of Vega.

Vega is a main-sequence star located in the constellation Lyra. Betelgeuse is a red supergiant star located in the constellation Orion. The mass of Betelgeuse is observed to be about 20 times the mass of the Sun, while the mass of Vega is estimated to be about 2.1 times the mass of the Sun. Therefore, the mass of Betelgeuse is theoretically estimated to be around 9.5 times the mass of Vega.

Experimentally,

The mass of Betelgeuse is 2.188 x10^31 kg

The mass of Vega is 4.246 x 10^30 kg

For the first four, we encounter common examples in everyday life, all to do with water:

Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.

Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.

Condensation - gas to liquid, e.g. water vapor (gas) to liquid -  water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation  in the atmosphere.

Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer

While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life.  Carbon dioxide however is a more common example.

Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.
