Answer

4.The objects have the same acceleration

Explanation

Acceleration due to gravity is the acceleration acquired by an object when falling freely.

Under normal conditions, different objects has different accelerations depending on their mass and surface area. This is brought about by the air resistance they experience as they fall.

The case is difference when they the experiment is carried out in a controlled condition. That is in vacuum. I this case the acceleration of the objects is the same.

Question
You are rolling on a skateboard with a constant velocity of 12 m/s. as you are moving you toss a baseball straight up into the air with a vertical speed of 25 m/s.    how long will it take the ball to land back in your hand? how high will the ball go before it falls back what is its peak height?
Solution 1

Your horizontal motion has no effect on the answers.
Your sister is standing on the sidewalk as you skate by.
At the same exact instant that you toss yours, she tosses
another baseball straight up at 25 m/s, and she gets exactly
the same answers as you get.

The acceleration of gravity is 9.8 m/s² down, so each baseball
loses 9.8 m/s of upward speed each second after you toss them.
They can only continue going up for  (25/9.8) = 2.55 seconds.
At that point, each ball has run out of upward gas, stops, turns
around, and starts falling.  It takes the same 2.55 seconds to
return to the same height from which it was tossed.  So each
ball takes (2 x 2.55) = 5.1 seconds to land back in your hands.

The average speed of each ball on the way up is

                (1/2) (speed at the bottom + speed at the top)

             = (1/2) (25 + 0)  =  12.5 m/s ,

and it spends 2.55 seconds rising.

The distance it covers upward is 

                           (average speed) x (time)

                        =      (12.5 m/s)  x  (2.55 sec)

                        =           31.875 meters .

There it is.  The physics and math are bullet-proof, but
the numbers are whacko.

From a skateboard, you tossed a baseball straight up
at  56 miles per hour ... fast enough for it to reach 105 feet,
possibly the height of a 7-story building, before it falls back !

Question
A regular series of pulses will produce a periodic : wave chord beat
Solution 1

Answer:

WAVE

Explanation:

As we know that pulse is a short disturbance which is produced in a given medium

When this short disturbance propagates in the medium continuously then it forms a continuous disturbance.

This is known as waves

So the wave is combination of pulse that travels in a given medium with periodic interval of time.

So here correct answer will be

WAVE

Solution 2
A. wave because as the pulses are sent out the move in a wave.
Question
A standing wave form is 10 m long between the first and sixth nodes. The wavelength is: 0.4 m 0.6 m 1.4 m 4.0 m
Solution 1

Answer:

Wavelength = 4.0 m

Explanation:

As we know that the distance between first and sixth nodes is given as 10 m

so here between first and sixth node the total number of loops are

N = 5

length of one loop is given by

\frac{\lambda}{2} = \frac{10}{5}

so here we have

\lambda = 2 \times \frac{10}{5}

\lambda = 4.0 m

so the wavelength of the standing wave here is of length 4.0 m

Solution 2
6nodes= 2.5wavelenghts
10cm/2.5= 4cm
1wavelenght= 4cm
Question
keeping the mass of the balls equal, decrease the distance between them. what happens to the force arrows?
Solution 1
If you decrease the distance, and the masses stay the same, the equation:
F_g = \frac{Gm_1m_2}{r^2}

Says that the force will get bigger by a factor of the distance your decreased by,
Solution 2

Answer:When the distance between the balls decreases, the size of the arrows increases. This shows that the gravitational pull between the balls also increases.

Question
Granite is uplifted by the movement of tectonic plates. It will most likely become _____. igneous rock sedimentary rock metamorphic rock magma
Solution 1

Answer;

Sedimentary rock

Granite is uplifted by the movement of tectonic plates. It will most likely become a sedimentary rock.

Explanation;

  • Granite is an intrusive igneous rock that is coarse-grained and light-colored, mainly composed of feldspar and quartz. ¬†It forms from the crystallization or the cooling of magma in the Earth's crust.
  • When igneous rocks such as granite undergo weathering and erosion they form sediments that are deposited, then compacted and cemented by the movement of tectonic plates resulting to the formation of sedimentary rocks.
Solution 2

Answer:

Sedimentary rock

Question
When water in clouds undergoes condensation, it can lead to?
Solution 1
It will lead to rain. I know this because as the clouds move over water sources like oceans, lakes, and rivers, the water evaporates and rises. The water then liquefies into little water droplets. As the cloud moves over more water the droplets get scrunched up and get bigger over time and soon they get heavy and gravity pulls the droplets down to earth as rain. The End.

Question
All of the following have been associated with amount of cortisol within the body except __________. A. experiencing problems with weight B. development of female sex characteristics C. experiencing stress D. blood sugar regulation
Solution 1

Answer: B. development of female sex

Development of female sex characteristic is not associated with the amount of cortisol in the body.

Explanation:

Cortisol is a steroid hormone secreted by the adrenal gland. It facilitates stress response, regulates blood sugar level and helps fight infections. High cortisol level leads to Cushing syndrome and low cortisol level leads to Addison disease.

Obesity is a  symptom of Cushing syndrome while weight loss is a symptom of Addison disease. Thus levels of cortisol can affect body weight as well.  When in a stressful situation, our body pumps excess cortisol.

Cortisol level in our body is generally high in the mornings and low in the midnight.

Solution 2

Answer:

B. development of female sex characteristics

Explanation:

Cortisol is known as "Stress Hormone" for the reason that it is secreted in response to the stress. But it is more than just stress hormone and has a lot of other functions too.

It is made in the Adrenal glands. Almost all the body cells have cortisol receptors. This hormone helps in regulating blood pressure, blood sugar levels, metabolism of the body and fight infections. High levels of cortisol will result in "Cushing Syndrome" and low level of cortisol will result in "Addison disease". People with "Cushing Syndrome" gain weight rapidly while people with Addison Disease will lose weight rapidly.

The development of female sex characteristics doesn't depend on cortisol. It depends on the absence of Testosterone. If testosterone is present the fetus will develop into a male else a female.

Question
An electric generator transforms mechanical energy into electrical energy. This process could be done by which of these? A) Using wind to spin a magnet around. B) Connecting a battery to a coil of wire. C) Turning a wheel that contains electrons. D) Spinning a coil of wire near a large magnet.
Solution 1

Answer:

D) Spinning a coil of wire near a large magnet.

Explanation:

From Faraday's law of induction, when a conducting coil of wire is placed in changing magnetic flux, an emf is induced which produces current in the coil.

Induced emf is given by:

e = -\frac{d\phi}{dt}

A generator is based on the same principle.

The mechanical energy of rotating coil is converted to electrical energy when current is induced. Thus, the correct option is D) Spinning a coil of wire near a large magnet.
