If there was no friction, a ball rolling on a perfectly horizontal floor would never stop unless it struck something. It would keep on going and going and going even though gravity is still acting on it. Why won’t gravity stop the rolling ball?

If force is 150N and area 25cm squared what is the pressure

Answers

Explanation:

Force = 150N

Area = 25cm = 25/10000m²

Pressure = F/A = 150/(25/10000) = 1500000/25 = 60000Pa.

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

Stellar Spectra Classification The patterns of lines detected in stellar spectra are used by astronomers to classify stars into spectral classes. These spectral classes are a measure of a star's surface temperature since the temperature of a star dictates which absorption lines are present in its spectrum.

1. If there are two objects of equal size but object A is heavier than object B, which statement is TRUE according to Newton’s second law of physics?
A.
Object A will require less force to be set in motion and will travel faster.
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.

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 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
