Explanation:
The force of gravity is the physical force exerted by the mass of a planet on the objects that are within its gravitational field. In other words, this law establishes that bodies, by simply having mass, experience a force of attraction to other bodies with mass.
The force of gravity depends on the mass of each object. The force with which two objects are attracted is proportional to their mass and decreases rapidly with distance:
where G is the universal gravitation constant, whose value is
G=6.673*10⁻¹¹
This expression indicates that the gravitational force that a point mass M exerts on another point mass m that is at a distance r from the previous one is directly proportional to the product of the masses and inversely proportional to the square of the distances that separates them.
Given the above, it is possible to say that two reasons why we feel the Earth's gravity more strongly than the moon's gravity are:
- Being the mass of a person the same, the mass of the Earth is greater than the mass of the Moon
- The distance r between the Earth and us is much closer than the distance r between the Moon and us (remember that the Earth exerts its force of gravity from the center)
This causes the force exerted by the Earth on us to be much greater.
1). The Earth has about 80 times as much mass as the Moon has.
2). The Earth is closer to many of us than the Moon is.

Predator is an organism or group of organisms which kills and consumes other organisms in an ecosystem.Prey is an organism or group of organism which is killed by other organism in order to obtain them as food. Predation and prey interaction is necessary to make balance in surplus increase in population of prey.
An example including two different species might can compete over the same prey is a tiger and lion species competing for a same prey zebra. This shows a predator and prey relationship.

The friction arrow in an FBD for a moving object point is in opposite way to motion. Because friction always works in the opposite direction of the motion of the object.
Answer: Option D
Explanation:
When two object come into contact, the contact force come into play. Now, one component of the contact force i.e. the normal forces act perpendicularly at the direction of motion. Whereas, the frictional forces always acts parallel at the direction of the force acting on the object but in the opposite way.
For example, if we slide a book on the table to the right hand side, the exact equal and opposite frictional force will induce in the opposite direction, tempting to reduce the motion.

The answer would be B. Earth is an electromagnet.
The Earth is a giant electromagnet. It's electromagnetic field is generated from the currents of electricity coming from molten metal flowing in the outer core of our Earth. The heat from the inner core causes convection and that is how electric current flows within Earth.

Answer:
The correct answer is D.
Explanation:
It is important to use the correct number of significant numbers when reporting the results of an experiment because they indicate the accuracy of the measurements. Significant numbers in measurement are those that provide fundamental information about uncertainty or accuracy of measurement.
Have a nice day!
Answer:
D
Explanation:
Scientists use significant figures to avoid claiming more accuracy in a calculation than they actually know.
