Answer:
1.308104*10^-8 N (1.31*10^-8 N when rounded)
Explanation:
The mathematical formula for gravitational force is F = G Mm /r^2 where G is the gravitational constant which is measured 6.674 *10^ − 11 N (m/kg) ^2.
Since both objects, M and m, have masses of 70kg and the distance r is 5 meters, then we can plug these values into the formula:
F=GMm/r^2
F=(6.674*10^-11)(70)(70)/(5^2)
F=(6.674*10^-11)(4900)/25
F=(3.27026*10^-7)/25
F=1.308104*10^-8
So the gravitational force of attraction between the two objects is 1.308104*10^-8 N.

How does the value and direction of the restoring force change as the spring constant or displacement is changed?
Answers
Answer:
The effect of gravity is only to shift the equilibrium point, so at equilibrium (at rest), a vertical spring will be extended as compared with the same spring in a horizontal position. But this does not affect the period.
As the spring constant or displacement is changed, the value and direction of the restoring force change, and they are always toward the equilibrium position of the spring when it is stretched.
What is the significance of the restoring force?When an object is relaxed or stretched, it is responsible for returning it to its original equilibrium position, such as a spring when stretched, and the force is directly proportional to the displacement and acts in the opposite direction of the displacement, the restoring force is responsible for the oscillations and waves, and its properties.
Hence, as the spring constant or displacement is changed, the value and direction of the restoring force change, and they are always toward the equilibrium position of the spring when it is stretched.

A. Nuclear fusion requires very high pressures and temperatures.
B. Nuclear fusion occurs spontaneously on Earth.
C. Nuclear fusion is used in power plants to produce electricity.
D. Nuclear fusion is used to power aircraft carriers.
Answers
Answer:
A. Nuclear fusion requires very high pressures and temperatures.
Explanation:
Nuclear fusion requires very high pressures and temperatures is one way that nuclear fusion differs from nuclear fission. Hence option A is correct.
What is nuclear fusion and fission ?Nuclear fission and fusion processes are the two basic types of nuclear reactions. Nuclear fusion is a process in which two or more light nuclei collide to generate a heavier nucleus. Nuclear fusion occurs in elements with a low atomic number, such as hydrogen. Nuclear fusion is the inverse process of nuclear fission, in which heavy atoms disperse and generate lighter elements. Nuclear fusion and fission both yield enormous amounts of energy.
A nuclear process in which atomic nuclei of low atomic number fuse to generate a heavier nucleus, releasing energy.
Because of nuclear fusion, every star in the cosmos, including the sun, is alive. They generate massive amounts of heat as a result of this activity.
Fission is a nuclear process that occurs when a heavy nucleus breaks spontaneously or when it collides with another particle, releasing energy. Nuclear fission occurs when the nucleus of an atom breaks into lighter nuclei as a result of a nuclear reaction. This decay can occur naturally as a result of radioactive decay, or it can be replicated in a laboratory by attaining the requisite circumstances (bombarding with neutrinos). The resultant pieces have a lower total mass than the original. In the preceding process, the missing mass is turned into nuclear energy.
Hence option A is correct. it requires high pressure and high temperature and it occurs in sun.

An astronaut has a mass of 70kg.
The force of gravity on the Moon is approximately 1.5N/kg.
Calculate the weight of the astronaut when they are on the Moon.
Weight = .............................................................. N
Answers
Answer:
Weight = 105 Newton
Explanation:
Given the following data;
Mass = 70kg
Force of gravity = 1.5N/kg
To find the weight;
Weight = mass * force of gravity
Substituting into the equation, we have;
Weight = 70 * 1.5
Weight = 105 Newton
Therefore, the weight of the astronaut when they are on the Moon is 105 Newton.

i would use the grapefruit and throw it into the water 1 by 1 one leaving sometime in between to see the sharks reaction to it. If they get attracted to it i would throw 1 in then use the bucket to push foward as fast as i can with all of my strength so i can get an equal and opposite reaction from the water to push me foward, i would keep this up for as long as i can. The size of the bucket and the amount of grapefruit were never specified so i would use this for my benefit to say its enough to get to shore

5. A student is investigating the relationship between pressure,
temperature, and entropy. A student manages to obtain a sample of ice,
water, and water vapor that all coexist at the same temperature called
the triple point. Which will have the greatest entropy at the triple point?
Answers
Answer:
The water vapor will have the greatest entropy at the triple point
Explanation:
At the triple point of water, which has the properties of 0.0075°C temperature and 6.11657 mbar pressure, solid ice, liquid water and water vapor exist together in a location
According to Professor Stephen Lower on LibreTexts website entropy is a measure the extent to which thermal energy is shared and spread in a system
The change in entropy, ΔS = ΔH/T
The heat change in [tex]\Delta H_{melting}[/tex] = 6.01 kJ/mol
The heat change in vaporization, [tex]\Delta H_{vaporization}[/tex] = 45.05 kJ/mol
The heat change in sublimation, [tex]\Delta H_{sublimation}[/tex] = 51.06 kJ/mol
Therefore, the entropy of the water vapor [tex]S_{water \ vapor}}[/tex] > The entropy of liquid water, [tex]S_{Liquid \ water}[/tex] > The entropy of the solid ice, [tex]S_{Solid \, ice}[/tex]
The portion with the highest entropy at the triple point is the water vapor
The water vapor will have the greatest entropy at the triple point
The graph show a distance travelled by four cars (A, B, C& D) over a period of time . Which car travelled at a greatest speed? *
Answers
Answer:
Car A traveled with the greatest speed.
Explanation:
We know that the steepness of the slope of the line on the distance-time graph represents speed.
Important Tip:
If the slope of the line is more vertical — steep — the speed will be fast.If the slope of the line is more horizontal — flatter — the speed will be slow.For example, at t = 5 seconds, the A car has covered more than 80 meters while all the other cars have covered less than 80 meters during the same period.
IIn fact, during the entire journey, it is clear that from the graph that the slope of the line of A car is more vertical — steep — than the slopes of cars B, C, and D.
Therefore, car A traveled with the greatest speed.

A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m. How much work is done to move the lift this height?
Answers
300N + 950N = 1250N
1250N x 12m = 15000J
Answer = 15000J of work is done.
The total work done to move the lift to this height if, A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m, is 15000 Joules.
What is work done?When an object is moved over a distance by an external force, at least a portion of that force must be applied in the direction of the displacement. This is known as work in physics.
Given:
A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m,
Calculate the total force as shown below,
Total force = Lift weight + man weight
Total force = 300 + 950
Total force = 1250 N
Calculate the work done as shown below,
The work done = Total force × displacement by total force
The work done = 1250 × 12
The work done = 15000 Joules
Thus, the total work done is 15000 joules.
