The force of 2812.5 N is being exerted by the chain.
What is force?An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.
Given that:
Mass of the hunk of anorthosite moon rock : m = 500.0 kg.
Acceleration of the hunk: a = 4.0 m/s².
Acceleration due to gravity in moon = 1.625 m/s².
So, required force = 500.0(4.0 +1.625) n = 2812.5 N.
The force of 2812.5 N is being exerted by the chain.

Explain why we draw straight lines to show rays of light?
Answer:
Because light always travels in straight line.
Explanation:
The fact that light travels can be demonstrated by putting an object in its path. If the object is opaque the result is a degree of blackness on the other side of it which is due to the absence of the light. ... As light does appear to travel in straight lines then light is usually modelled as straight lines in drawings.

Explanation:
The correct answer is C because it puts equivalent measurements in the equivalent cup size. Both cups in answer C are the same measurement: 200 mL. The water in both cups is also the same measurement: 100 mL of 70 degrees Celsius. This is important because equivalent measurements for everything mean the experiment will be fair, equal, and accurate. If the measurements were not equal to each other, your experiment would not be as accurate.

Explanation:
An object has an acceleration of 6.0 m/s/s. If the NetForce was tripled and the mass was halved, then the new acceleration would be _____ m/s/s
Hi there!
We know that:
∑F = ma
If you tripled the net force and halved the mass:
3F = 1/2ma
Rearrange for 'a':
3F × 2 = ma
6F = ma
Thus, the new acceleration would be 6 times the original, or 36 m/s².

Identify each of the following statements related to universal gravitation as either true or false. False The gravitational field around a planet is oriented radially outward. True Stars must be at least 2 or 3 times more massive than our sun in order to become a black hole. False Orbiting astronauts are weightless because of the absence of a support force. False The outer planets in our solar system wobble in their orbits because the gravitational effects of the sun are so small. False The earth is falling toward the sun. False As you move farther from the earth, its gravitational force acting on you increases.
The characteristics of the universal gravitation law allow finding the results for which statements are true:
2. Real stars must be at least 2 to 3 times more massive than our sun to become a black hole.
All the others are false.
The universal gravitational law states that the gravitational force is always attractive and is proportional to the masses and inversely proportional to the square of the distance.
[tex]F = - G \frac{Mm}{r^2}[/tex]
Where F is the force, G is the universal gravitational constant, M and m are the masses and r the distance between the bodies.
Let's analyze the expressions:
1. The gravitational field around a planet is oriented radically outward
False. The force is attractive therefore it is directed towards the center of the planet.
2. Real stars must be at least 2 to 3 times more massive than our sun to become a black hole.
True. From observations of super-novae the minimum mass is 3 solar masses.
3. Astronauts in orbit are weightless due to the absence of a supporting force.
False. Astronauts have no weight because the force of gravity binds to change the direction of their velocity.
4. The outer planets of our solar system wobble in their orbits because the gravitational effects of the sun are very small.
False. The attraction of the sun decreases with the square of the distance, but the wobble is due to the attraction of the other large planets in this area.
5. The earth falls towards the sun.
False. The earth has a speed parallel to the orbit around the sun and the acceleration due to the attraction of the sun changes the direction of the orbital velocity, but the earth is not directed at the sun.
6, As you move away from the ground, the gravitational force acting on you increases.
False. The gravitational force is inversely proportional to the distance, therefore it decreases when leaving the earth.
In conclusion with the characteristics of the universal gravitation law we can find which statements are true:
2. Real stars must be at least 2 to 3 times more massive than our sun to become a black hole.
All the others are false.

Photosynthesis is a process in which green plants manufacture there own food in the presence of sunlight through the equation below
6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂
From the equation above, it can be seen that aside from the food (C₆H₁₂O₆) produced by green plants during photosynthesis, science has assisted us in knowing that these green plants take-up the carbon dioxide (CO₂) that is exhaled by humans and release the oxygen (O₂) that is inhaled by humans thereby purifying the air of the surrounding they are found. This concept has made man understand the importance of planting in residential areas.
Depletion of the Ozone layer; the ozone layer is a layer in the earth stratosphere which shields the earth from direct sunlight/rays. Over the years, the burning of hydrocarbon on earth has caused the depletion of this layer thereby exposing the earth to more direct sunlight from the sun. Science has had an impact in the thinking of man in this regard by making us more conscious of the risk of burning these hydrocarbons which has led to the collective efforts by governments across the world to minimize the burning of these substances.
Rain; rain are droplets of water that fall from the atmosphere. Rain formation occurs when water (in the form of ocean, river and/or seas) are evaporated into the atmosphere as a result of heat from the sun. These evaporated water molecule rises and cools down to form and form a cloud It is then returned to earth in the form of rain. This explanation changes the mythical understanding of rain in different culture

What is the force that counteracts the thrust force for flight?
The force which counteracts the thrust force for the flight is known as the drag force, as it opposes the flow.
What is drag force?Drag is a force that opposes an object's relative motion to a fluid environment in the field of fluid dynamics. It may be among two liquid film (or surfaces) or in between a liquid and a flat wall. The drag force is influenced by velocity, as opposed to other resistive forces like dry contact, which are essentially independent of it.
When a flow is moving at low or high speed, the drag force is equal to the speed for low pressure and to the square of the velocity for high-speed flow. Although viscous friction is what ultimately causes drag, turbulent drag is unaffected by viscosity.
A force in physics is an input that has the power to change an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe forces.

If F = 4.0 N and m = 2.0 kg, what is the magnitude a of the acceleration for the block shown below? The surface is frictionless. *
The magnitude of the acceleration of the block is 3.5 [tex]\bold{m/s^2.}[/tex]
The correct option is (C) 3.5 [tex]\bold{m/s^2.}[/tex]
What do you mean by acceleration?Acceleration is the rate of change of velocity with time.
By Newton’s Second law
This law establishes the relationship between the net applied force on an object with the resultant acceleration. For a constant magnitude of force, the more is the mass of the object, the lesser will be its acceleration.
Given,
The mass of the block is 2.0 kg.
The force in the horizontal direction on the block is [tex]\bold{4.0 N + 4.0 N \cos 40{}^\circ.}[/tex]
a is the acceleration in the horizontal direction.
The acceleration for the block can be determined using Newton’s Second law,
[tex]\begin{aligned} \Sigma F&=ma \\ F+F\cos 40{}^\circ &=ma \\ a&=\frac{F\left( 1+\cos 40{}^\circ \right)}{m} \\ &=\frac{4.0\text{ N}\left( 1.766 \right)}{2.0\text{ kg}} \\ &=3.5\text{ m/}{{\text{s}}^{2}} \end{aligned}[/tex]

A satellite is orbiting Earth at a speed of approximately 4,000 m/s. Which of these distances is most likely the orbital radius of the satellite’s motion?
The radius of the satellite's motion is 2.49 × 10⁷ m
Since the centripetal force, F = mv²/r equals the gravitational force, F' = GMm/r² on the satellite,
F = F'
mv²/r = GMm/r²
v² = GM/r
Making r subject of the formula, we have
r = GM/v² where r = radius of satellite's motion, G = universal gravitational constant = 6.67 × 10⁻¹¹ Nm²/kg², M = mass of earth = 5.972 × 10²⁴ kg and v = speed of satellite = 4,000 m/s.
Substituting the values of the variables into the equation, we have
r = GM/v²
r = 6.67 × 10⁻¹¹ Nm²/kg² × 5.972 × 10²⁴ kg/(4,000 m/s)²
r = 39.83324 × 10¹³ Nm²/kg ÷ 16 × 10⁶ m²/s²
r = 2.4895775 × 10⁷ m
r ≅ 2.49 × 10⁷ m
So, the radius of the satellite's motion is 2.49 × 10⁷ m.
