Which of the following is most likely to happen when energy is transferred to an object A) the object will stay exactly the same B)The object Will begin to move C)the force on the object will decrease D) the mass of the object will increase
Answer:
B. the object will begin to move
Explanation:
If energy is transferred the object will definitely change so it CANNOT be "A". If you add energy the object will have more force so it CANNOT be "C". The mass of an object can't increase just by giving an object energy so it CANNOT be "D"
When energy is transferred to an object, the object is most likely to move either it gains a kinetic energy or it undergo a thermal vibration if thermal energy is applied.
What is energy transfer?Energy can be transferred from its high energetic area to less . All forms of energy can be transferred like this.For example, heat energy can be transferred through various modes such as conduction, convection, radiation etc.
When an object gain some energy its particles starts to vibrate and move apart. This makes the intermolecular force of attraction between molecules weaker than before and they tend to be more reactive.
The energy transferred to an object does not make any change in mass, or any of its innate properties or does not apply any force. Therefore, option B is correct.

Where mud you be standing if the Sun appears to be directly overhead at noon
Answer:
A
Explanation:
As the earth rotates through one revolution, a person standing on the equator traces out a circular path whose radius is equal to the radius of the earth (6.38×10^6). What is the average speed of this person in meters per second? If we are standing in latitude 43° north what is our average speed?
Answer:
The average speed will be "1038 mph".
Explanation:
Period for one revolution is:
T = 24 hours
= 86,400 sec
x = c = 2πr
The given values is:
r = 6.38×10⁶ m
Now,
⇒ [tex]T=\frac{2 \pi r}{v}[/tex]
Or,
⇒ [tex]v=\frac{2 \pi r}{T}[/tex]
On substituting the values, we get
[tex]=\frac{2 \pi (6.38\times 10^6)}{86,400}[/tex]
[tex]=464 \ min/sec[/tex]
[tex]=(464 \frac{min}{sec}) (\frac{3600 \ sec}{1 \ hour} )(\frac{1 \ mi}{1609 \ m} )[/tex]
[tex]=1038 \ mph[/tex]

A car, initially traveling 24.0ft/s, steadily speeds up to 58.0ft/s in 5.40s. Determine all unknowns and answer the following question.
How far did the car travel during this time?
Answer:
acceleration = 6.29 ft^2/s
distance traveled by car = 405 ft
Explanation:
formula 1 : u = v - (a*t)
where u = initial velocity
v = final velocity
a = acceleration
t = time.
solving for acceleration.
24 = 58 - (a*5.4)
a = (58 - 24)/ 5.4
a = 340/ 54 = 6.29 ft^2/s
formula 2: v = d/t - (a*t/2)
58 = d/5.4 - ((340*54)/20)
d = 405 ft
What is uniform acceleration
Answer:
It means zero acceleration.
Explanation:
When a body moves with constant velocity then it is said to be there is no rate of change of velocity takes place because it is constant. So the acceleration becomes zero or uniform acceleration.
A horse is grazing for food. It trots rightward 15 m to eat a carrot, then walks rightward 20 m, to another carrot, then turns leftwards to walk 4m, to bite an apple. The horse walks a total time of 74 seconds. What is the magnitude of its average velocity?
(** HINT- you may want to draw this out, remember with VELOCITY direction matters-opposite vectors cancel out-with SPEED direction does not matter).
Answer:
0.42sExplanation:
Velocity = Displacement/time
Displacement of the horse is the distance covered in a specified direction
Total distance of the horse towards the right = 15m + 20m = 35m
Total distance of the horse towards the left = 4m
Displacement = Distance towards the right - Distance towards the left
Displacement = 35m-4m
Displacement = 31m
Time taken = 74seconds
substitute the values gotten into the velocity formula
average velocity = 31m/74s
average velocity = 0.42m/s
Hence the magnitude of its average velocity is 0.42s
Cuál es el método que utiliza el factor de la gravedad y la difusión de un líquido sobre un sólido para separar las partes de una mezcla de varios líquidos mezclados entre sí
Answer:
chromatography
Explanation:
Chromatography is one of the powerful technique that is used to separate the mixed components of liquid or the gas mixtures.
In this technique the separation of the mixture by passing the mixture in some solution or some suspension through the medium where the components are made to move at some different rates.
The basic idea in this experiment is that the mixture sample is in mobile phase and it is forced either by pumping or by gravity or by capillary action through the stationary phase to separate the mixture.

A giraffe, standing 6.00 m tall, bites a branch off a tree to chew on the leaves
and lets the branch fall to the ground. How long does it take the branch to hit
the ground?
Answer:
1.11 s.
Explanation:
From the question given above, the following data were obtained:
Height (H) = 6 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =.?
The time taken for the branch to hit the ground can be obtained as follow:
H = ½gt²
6 = ½ × 9.8 × t²
6 = 4.9 × t²
Divide both side by 4.9
t² = 6/4.9
Take the square root of both side
t = √(6/4.9)
t = 1.11 s
Therefore, it will take 1.11 s for the branch to hit the ground.
Which example best represents balanced forces? an elevator stopped on the third floor a basketball shot into a hoop a sled sliding down a snowy hill a tow truck pulling a car out of a ditch
Answer:
an elevator stopping on the third floor
Explanation:
The example that best represent balanced force as regards this question is an elevator stopped on the third floor.
Balanced force can be regarded as resultant force that has a magnitude of zero when acted on an object. When forces that are been subjected on a body are zero then the force is balanced.In the case of the elevator, immediately it stopped at a particular floor, then it will gave a balanced force, because at that point all forces acting on it becomes zeroWhen a car is pushed from a ditch , the force is acting from a side so its not balancedExamples of balanced forces are;
The weight of object as well as normal force acting on it can be regarded as been balanced.When pushing a car at both opposite sides with the same forces.A lizard that hangs in vertical position.Therefore option A is correct, because balanced force exist as the elevator stopped.

Complete the paragraph to describe binary systems. A binary star system is made of (blank) stars, one of which is brighter than the other. Astronomers are able to detect the dimmer star because its gravity causes the bright star to (blank). Astronomers can also spot the dimmer star by observing a phenomenon called a(n) (black) binary.
