Forces on an object that do not change the motion of the object
Answers
Answer:
No
Explanation:The three main forces that stop moving objects are friction, gravity and wind resistance. Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.

Answers
EXPLANATION 2.The energy would then have to be stored and released as needed, similar to how renewable energies like wind and solar power are done. This requires additional planning and expense, but it is achievable. Capacitors have been used to achieve this storing on a lesser scale. On a bigger scale – in power plants, for example – massive rechargeable batteries are used to liquefy air or liquid
Answer:
Yes
Explanation:
The lightning current can travel even farther through water, metal fences, power lines or plumbing. Lightning current may enter a building and transfer through wires or plumbing and damage everything in its path.

Why is Christchurch, New Zealand’s air temperature cooler than usual during El Nino years?
Answers
Answer:
During normal years energy transfers from the ocean to the air. However, during El Nino years, the current is not as warm, so less energy will transfer from the current to the air, making Christchurch cooler than usual. During El Niño years, the normal prevailing winds are disrupted.

Why does the coil keep spinning?
Which way is electricity flowing?
Answers
Answer:
The coil keeps spinning because of the interaction between the magnetic field generated by the flow of electricity in the coil and the magnetic field of the permanent magnet surrounding it. This interaction creates a force that causes the coil to rotate continuously.
As for the direction of the electricity flow, it depends on the design of the coil and the direction of the magnetic field. If the coil is connected to a direct current (DC) source, the electricity will flow in a single direction. If the coil is connected to an alternating current (AC) source, the direction of the electricity flow will change periodically, typically many times per second.
In general, the direction of the electricity flow can be determined using Faraday's law of electromagnetic induction, which states that a changing magnetic field will induce an electromotive force (EMF) in a conductor, which will cause electricity to flow in the conductor. The direction of the induced EMF and the resulting electricity flow will depend on the direction of the changing magnetic field and the direction of the coil.
Explanation:
Answer:
The inertia of the rotating coil carries it through half of a turn, past the insulating paint. When the electric current starts to flow again, the twisting force is in the same direction as it was before. The coil continues to rotate in the same direction.
The permanent magnets exert forces on the electrical currents flowing through the loop of wire.
Light with a wavelength of 5.0 · 10-7 m strikes a surface that requires 2.0 ev to eject an electron. Calculate the energy, in joules, of one incident photon at this frequency.
_____ joules
4.0 x 10 -19
9.9 x 10 -32
1.1 x 10 -48
4.0 x 10 -49
Answers
Answer:
They are: -14 joules.
And the other answer is: 9.9 x 10-32.
Explanation:
Since to convert to joules it is necessary to add 4 with 9 decimal places to the first number and to the second number 25 decimal places are added.
--- Since 5.0 plus 4 and 9 decimals is: 9.9
--- As 10 - 7 plus 25 decimals: 10 - 32
--- And 9.9 in joules is 8.0 x 10 - 32 = - 22 and 8.0 x -22 is - 14. So they are - 14 joules.
--- And the other answer is: 9.9 x 10- 32

For this assignment, you will research how to design and build a solar cooker. Search reliable online sites
for “solar cookers.” After getting the materials you need from your teacher, you will present your initial
design as a drawing or illustration. You will then build your device and test its efficiency by warming up a
hot dog until it reaches an internal temperature of 165°F, recording how long it took you to reach this
temperature. Based on your tests, you will make recommendations on how to improve the design of your
solar cooker, and then present your final design and the logic that supports it in a lab report. Your lab
report should include a title, a list of materials that you used to build your solar cooker, a drawing of your
initial design, observations from your experimental tests, recommendations for a final design based on
what you know about radiation, a drawing of your final design, and the results of the efficiency test. To

Why can even a small injury to the cornea have a effect on vision
Answers
Answer:
It also plays a key role in vision. As light enters your eye, it gets refracted, or bent, by the cornea's curved edge. This helps determine how well your eye can focus on objects close-up and far away. If your cornea is damaged by disease, infection, or an injury, the resulting scars can affect your vision.

You will need a magnifying glass and a small piece of scrap paper for this demonstration.
a. Go outside on a sunny day and put the piece of paper on a patch of asphalt, concrete, or a large flat rock. Make sure there is no other combustible material or debris in the vicinity.
b. Hold the magnifying glass so it is close to the paper, with rays of sunlight shining through it. Move the magnifying glass side to side and close or away from the paper until the most concentrated ray of light is shining on the paper. This is the focal point for that magnifying glass.
c. Measure the distance between the focal point and magnifying glass. This is the focal length for that magnifying glass. (Be careful; if you hold the magnifying glass in that place for long enough, the paper will catch fire. Do not ever do this on your skin or clothing, as it can cause serious burns.)
