Answer:
Angle - 120 degrees, 2.093 radians and 0.33 revolution
Explanation:
Minute hand is on the 12 and the hour hand is on the 4.
The angle formed between 4 and 12 is
[tex]\frac{4}{12} * 360 = 120[/tex] degrees
The angle formed between 4 and 12 in radian is
[tex]\frac{\pi }{180} * 120 = 2.093[/tex] radians
The angle formed between 4 and 12 in revolution is
[tex]\frac{2.093 }{2 \pi } \\= \frac{2.093 }{2* 3.14} \\= 0.33[/tex] revolution

You might have heard the phrase ‘hot air rises'. Name the process of transferring energy using moving gas or liquid.
Answer: Convection
Explantion: Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection

How is the Physics definition of momentum different from the ""colloquial"" use of momentum
Answer:
Explanation:
You know, I never really thought about this very much. I've always just thought of it as M * V. But when you look at a dictionary definition, it says it is the motion of a body.
That means that speed can be a momentum. Speed is independent of direction. So the colloquial definition does not take into account a change in direction as being very relevant.
The answer then is direction. When physics uses v, it is also counting direction.
What is friction ridge skin?
The table provided shows data collected during an experiment .
Which of the following claims is supported by the data?
A. Gravitational force are proportional to the masses of the two objects.
B. Gravitational forces are strongest between objects with identical masses.
C. Gravitational forces are weakest when one object is more massive than the other.
Answer:
Explanation: the table shows during an experiment
Gravitational forces are strongest between objects with identical masses, claims are supported by the data. Option B is correct.
What is Newton's law of gravitation?Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.
Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.
When mass increases and distance reduces, gravity rises. Gravity also lowers when the distance between two points grows and the mass decreases.
From the table, it is observed that gravitational forces are strongest between objects with identical masses, claims are supported by the data.
Hence, option B is correct.

If a total of 1250 offspring were obtained from your cross, determine the number of offspring that you would expect to obtain that represent a single crossover event between pr and vg if interference does not occur.
Answer:
106 single crossover events
Explanation:
Total number of offspring = 1250
Determine the number of offspring that would be expected
( Rf between the genes vg and Pr ) * ( Total number of progeny )
= 0.125 * 1250 ≈ 156 ( value for single and double crossovers )
next :
( value of the Rf of double crossovers ) * ( Total number of progeny )
= (0.322 * 0.125) = 0.04025 * 1250 = 50
Hence the number of offspring expected to obtain/represent a single crossover event between pr and vg
= 156 - 50 = 106

Answer:
gravitational force
Explanation:
an object with mass attractive another object with mass
ANSWER:
GRAVITATIONAL FORCE
EXPLANATION :

Why do eclipses not happen every lunar cycle? (If someone could explain this in a paragraph? it doesn’t have to be very descriptive or detailed)
Answer:
Exploratorium Senior Scientist Paul Doherty explains why not—the orbit of the moon is tilted relative to the orbit of the Earth around the sun, so the moon often passes below or above Earth. At those times, it does not cross the line between the sun and the Earth, and therefore does not create a solar eclipse.
Explanation:
Hope it helps
Answer:
It's true that the moon goes around Earth every month, but it doesn't always get in Earth's shadow. The moon's path around Earth is tilted compared to Earth's orbit around the sun. The moon can be behind Earth but still get hit by light from the sun. ... This is why we don't get a lunar eclipse every month.

A ball has 17 J of kinetic energy and its mechanical is 25 J
If the ball has a mass of 3.2 KG what is it’s height above ground?
Answer:
0.255m
Explanation:
The total mechanical energy of the ball is given 25 J. The potential energy of the ball is 8 J. Then, the height of the ball above the ground is 0.25 m.
What is kinetic energy ?Kinetic energy of an object is the energy generated by virtue of its motion whereas potential energy is generated by virtue of its position at a height from the ground.
The sum of kinetic and potential energy of the object is called its mechanical energy.
given Ke of the ball = 17 J
mechanical energy = 25 J
then potential energy = 25 J - 17 J = 8 J.
We have the relation between potential energy, mass and height h as :
p = mgh .
given the mass m = 3.2 kg
g = 9.8 m/s²
then, h = p / (mg)
h = 8 J / (3.2 kg× 9.8 m/s² )
= 0.25 m.
Therefore, the height of the ball above the ground is 0.25 m.
