The greatest gravitational force would occur between the moon and Earth. The correct option is D.
What is Gravitation?The force of gravity, also known as gravitation, affects every material object in the universe. The force of gravity tends to draw any two objects or particles with nonzero mass toward one another. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.
The two forces, which are equal in strength and move in the opposite direction, pair up to interact with various objects. As a result, the pull of Earth on the Moon is equal to and opposes the pull of the Moon on Earth.
Amongst the given options the greatest force is between the moon and the earth.
Hence, the greatest gravitational force would occur between the moon and Earth. The correct option is D.

Mass is a measure of the amount of matter in a substance. Mass can be measured using a triple beam balance. Hence option (A) is correct.
What is mass?In physics, mass is a quantitative measurement of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force. The change caused by an applied force is smaller the more mass a body has. The kilograms serves as the unit of mass in the International System of Units (SI).
The conservation of mass principle states that no matter how an object's component pieces are rearranged, the object's overall mass remains constant. If a body splits into parts, the mass also splits into pieces, therefore the original mass is equal to the sum of the masses of the individual fragments. Alternatively, if two or more particles are combined, the mass of the resulting composite equals the total of the masses of the individual particles. This rule is not always accurate, though.

Calculate the percentage of the Sun's mass that will
be converted to energy in the remainder of its
lifetime.
Percentage of mass converted to energy =
Answer:
Percentage of mass converted to energy = 99.9 %
Explanation:
By far most of the solar system's mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star. Seen from afar (on the scale of distances between stars) the presence of the solar system would not be obvious. We would simply see a normal-looking star. Perhaps we would pick up the presence of Jupiter, which makes up two thirds or so of the solar system outside of the Sun, by mass.

a ball is rolled of the edge of a table with a
horizontal relocity of 10 m/s .What will be the ball's
velocity 0.10s later?
Answer:
Approximately [tex]10\; \rm m \cdot s^{-1}[/tex] at [tex]5.6^\circ[/tex] below the horizon.
Horizontal component of velocity: [tex]10\; \rm m \cdot s^{-1}[/tex].Vertical component of velocity: [tex]0.981\; \rm m\cdot s^{-1}[/tex] (downwards.)(Assumption: air resistance on the ball is negligible; [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex].)
Explanation:
Assume that the air resistance on the ball is negligible. The horizontal component of the velocity of the ball would stay the same at [tex]10\; \rm m \cdot s^{-1}[/tex] until the ball reaches the ground.
On the other hand, the vertical component of the ball would increase (downwards) at a rate of [tex]g = 9.81\; \rm m\cdot s^{-2}[/tex] (where [tex]g[/tex] is the acceleration due to gravity.) In [tex]0.1\; \rm s[/tex], the vertical component of the velocity of this ball would have increased by [tex]9.81\; \rm m \cdot s^{-2} \times 0.10\; \rm s = 0.981\; \rm m \cdot s^{-1}[/tex].
However, right after the ball rolled off the edge of the table, the vertical component of the velocity of this ball was [tex]0\; \rm m\cdot s^{-1}[/tex]. Hence, [tex]0.10\; \rm s[/tex] after the ball rolled off the table, the vertical component of the velocity of this ball would be [tex]0\; \rm m \cdot s^{-1} + 0.981\; \rm m\cdot s^{-1} = 0.981\; \rm m \cdot s^{-1}[/tex].
Calculate the magnitude of the velocity of this ball. Let [tex]v_{x}[/tex] and [tex]v_{y}[/tex] and denote the horizontal and vertical component of the velocity of this ball, respectively. The magnitude of the velocity of this ball would be [tex]\displaystyle \sqrt{{v_x}^{2} + {v_y}^{2}}[/tex].
At [tex]0.10\; \rm s[/tex] after the ball rolled off the table, [tex]v_x = 10\; \rm m \cdot s^{-1}[/tex] while [tex]v_y = 0.981\; \rm m \cdot s^{-1}[/tex]. Calculate the magnitude of the velocity of the ball at this moment:
[tex]\begin{aligned} \| v \| &= \sqrt{{v_x}^{2} + {v_y}^{2}} \\ &= \sqrt{\left(10\; \rm m \cdot s^{-1}\right)^{2} + \left(0.981\; \rm m \cdot s^{-1}\right)^{2}} \\ &\approx 10.0\; \rm m\cdot s^{-1}\end{aligned}[/tex].
Calculate the angle between the horizon and the velocity of the ball (a vector) at that moment. Let [tex]\theta[/tex] denote that angle.
[tex]\displaystyle \tan \theta = \frac{\text{rise}}{\text{run}}[/tex].
For the vector representing the velocity of this ball:
[tex]\displaystyle \tan \theta = \frac{0.981\; \rm m \cdot s^{-1}}{10\; \rm m \cdot s^{-1}} = 0.0981[/tex].
Calculate the size of this angle:
[tex]\theta = \arctan 0.0981 \approx 5.62^\circ[/tex].
Notice that the vertical component of the velocity of this ball at that moment points downwards (towards the ground.) Hence, the corresponding velocity should point below the horizon.

The weight of the object on the surface of earth would be 5kg. The weight of the object on the surface of moon would be 5/6= 0.83 as the weight of any object on earth is six times than that on moon.
A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The block weighs 1587 g. From this information, calculate the density of lead.
Answer:
11.3 g/cm^3
Explanation:
density = mass/volume
volume of rectangular prism = length * width * height
volume = (4.50 cm)(5.20 cm)(6.00 cm) = 140.4 cm^3
mass = 1587 g
density = (1587 g)/(140.4 cm^3)
density = 11.3 g/cm^3

I'll do coal. and maybe a little more.
Explanation:
Coal What is it?
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.
Coal How we obtain it:
Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
Coal Pros:
Coal is plentiful in many places and it is easy to access through mining, so people rely on it to produce energy. Coal is easy to store. Once it is mined it can be safely stored with no hazard of fire or explosion like there is with gas or oil. It is relatively easy and inexpensive to convert coal into energy.
Coal Cons:
Coal is nonrenewable. Coal contains the most CO2 per BTU, the largest contributor to global warming. Severe environmental, social, and health, and safety impacts of coal mining. The devastation of the environment around coal mines is heavy. High cost of transporting coal to centralized power plants. Coal is really dirty and not good.

Solar What is it?
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.
Solar How we obtain it:
Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.
Solar Pros:
It's clean energy. Solar power is pollution-free and causes no greenhouse gases to be emitted after installation. It has reduced dependence on foreign oil and fossil fuels. It is renewable clean power that is available every day of the year, even cloudy days produce some power. It gives a return on investment unlike paying for utility bills.
Solar Cons:
Solar doesn't work at night. Solar panels are not attractive. You can't install a home solar system yourself. My roof isn't right for solar. Solar hurts the environment. Not all solar panels are high quality.

How does an atom stay intact without collapsing
Answer:
The electron cloud has a very small mass, but it makes up most of the space of the atom. The electrons have a negative charge, and the protons have a positive charge. Due to the charges in the atom, that is how the atom stays together, by attraction of the electric charges present in the atom.

Help ASAP Electroscope problem
Assume you have a gold leaf electroscope
whose leaves are positively charged. If you bring an electrically neutral rod close to it the leaves: A-diverge more B-diverge less C-their divergence doesn't change D-none of the above
Answer:
An excess of positive (or negative) charge causes the leaves to diverge
Bringing a neutral rod in the vicinity of the electroscope will cause some of the positive charge to leave the leaves (making the electrically neutral rod negative at the tip) causing the leaves to converge.
What resultant force would accelerate an 810kg mass at 6.7 m/s squared?
Answer:
you need to multiply them and then you have your answer eg = 810 × 6.7 = 5427kg
Resultant force would accelerate an 810 kg mass at 6.7 m/s² 5427 N
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in the question,
Acceleration (a) = 6.7 m/s²
Mass (m) = 810 kg
Force (F) = ?
We know
F = M * a
F = 810 * 6.7
F = 5427 N
Resultant force would accelerate an 810 kg mass at 6.7 m/s² 5427 N

1 watt is the same as the transfer of ____
joules per second. What number completes the sentence?
Answer:
1 watt is the same as the transfer of 1 joules per second.
1 watt is the same as the transfer of energy at a rate of 1 joule per second.
A watt is a unit of power, representing the amount of energy transferred or converted per unit of time. Specifically, 1 watt is equivalent to 1 joule of energy being transferred every second. It is a common metric used to measure the rate of energy flow or work done in various systems. For example, a 100-watt light bulb converts electrical energy into light and heat at a rate of 100 joules per second. Understanding power in terms of watts helps us quantify and compare the efficiency and performance of different devices and processes.
