If the mass of an object is 100 and Net force is 400, what would be the Acceleration?
And explain.

Answers

Answer:

[tex]4m/s^{2}[/tex]

Explanation:

I'm assuming the units for force and mass are Newtons and kilograms, respectively.

Rearranging Newton's first law (F=m*a) to solve for acceleration:

F=m*a

[tex]a=\frac{F}{m}=\frac{400 N}{100 kg}=4m/s^{2}[/tex]

The acceleration is 4 meters per second squared and was found by rearranging Newton's first law in order to solve for acceleration.

Answers

Answer:

B Both are directly related to movement.

Endocrine system and muscular system are directly related to movement while both stretching and constricting exercises are important for muscle health. So, the correct options for 1 and 2 are B and A respectively.

What is Endocrine system?

The endocrine system is defined as the communication system made up of feedback loops that send hormones released by an organism's internal glands into the circulatory system, controlling distant target organs. The neurological control center for all endocrine systems in vertebrates is the hypothalamus. The endocrine glands lack ducts that would transport their output to the surface. These are known as glands without ducts.

Growth and development, metabolism, and reproduction are just a few of the essential processes in the body that are regulated by the hormones the endocrine system secretes. Movement has a close relationship with the endocrine and muscle systems.

Therefore, the correct options for 1 and 2 are B and A respectively.

A force unit is defined as the product of a mass unit and a unit of

acceleration.


time.


velocity.

displacement.

Answers

Answer:

A force unit is defined as the product of a mass unit and a unit of acceleration.

Answer:

Force can be defined as a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object.

Explanation:

Force = M (Mass) * A (Acceleration)

The SI unit of Mass = KG

S.I. unit of acceleration is m/sec/sec = m/sec2

Hence, Unit of force is Kg m/Sec2

Since force is used so often, S. I. gives this unit a special name:

1 Newton = 1 kg m/sec2

a body has a weight of 2.8 Newtons what is the Mass of the body in grams​

Answers

Answer:

285.7 g

Explanation:

Weight = mass x gravity

mass has units of kilograms

gravity is 9.8 m/s²

newton units are kg m / s²

So:

2.8 kg m/s² = mass x 9.8 m/s²

Divide both sides by 9.8

2.8 kg m/s²

----------------  =  mass in kg  = 0.2857kg

9.8 m/s²

Convert kilograms to grams by multiplying by 1000

0.2857kg        1000 g

--------------  X  ---------------  = 285.7g

       1                  1 kg

what is the central idea for stacking rocks vertically to test the effects of forces

Answers

Answer:

You can see how forces can stack on one another by comparing the normal force of the bottom most rock to the normal force of the upper most rock.

Explanation:

Say you have 3 rocks all with mass m=3kg

These 3 rocks will all have the gravitational force of -29.4N (multiply 3kg by -9.8m/s^2)

If none of the rocks are stacked, then they all have the same normal force as well (29.4N)

However, stack them, and see how their normal forces change.

m1 will continue to have a normal force of 29.4N

m2 will now have a normal force of 58.8

m3 will now have a normal force of 88.2

Though they all retain the same gravitational force, their normal force changes depending on the forces acting down on them.

Mass 1 have no forces acting downwards other than gravity.

Mass 2 has the force of mass 1 and gravity acting down on it.

Mass 3 has the force of mass 1, mass 2, and gravity acting down on it.

B.
Object B will require less force to be set in motion and will travel faster.
C.
Object A will require more force to be set in motion but will travel faster than object B.
D.
Object B will require more force to be set in motion but will travel faster than object A.

2. For athletes, a focus on body mechanics improves the effectiveness of their efforts.
A.
True

B.
False

Answers

The answers are 1. According to Newton's second law, object A, being heavier, requires more force to be set in motion and will travel faster than object B. The correct answer is options C. and 2. Focusing on body mechanics is important for athletes as it improves their effectiveness, and technique, and reduces the risk of injury is a true statement.

1. According to Newton’s second law of physics, if there are two objects of equal size but object A is heavier than object B, then the statement that is true is option C: Object A will require more force to be set in motion but will travel faster than object B. Newton's second law of motion states that acceleration is directly proportional to the force applied and inversely proportional to the object's mass. Since both objects are of equal size but object A is heavier, it will require more force to be set in motion. However, once in motion, it will have more inertia and travel faster than object B.2. The statement "For athletes, a focus on body mechanics improves the effectiveness of their efforts" is True. Body mechanics refers to the way in which the body moves and maintains balance while performing a physical task. Athletes need to have proper body mechanics to achieve maximum efficiency and reduce the risk of injury. By focusing on their body mechanics, athletes can improve their technique, reduce unnecessary movements, and improve their overall performance. Good body mechanics can also help to prevent injury and reduce wear and tear on the body. Therefore, a focus on body mechanics is essential for athletes to maximize their performance while minimizing their risk of injury. In summary, Newton's second law states that a heavier object requires more force to be set in motion, while a focus on body mechanics can improve the effectiveness of athletes' efforts.
