how can you reduce the percentage uncertainty in measurements that you make?​

Answers

Answer:

For example, one method for estimating the length of time it takes something to occur is to time it once using a stopwatch. You can reduce the uncertainty in this estimate by repeating the measurement and taking the average.

There are a lot of way to reduce the uncertainty however with real life sciences like quantum mechanics it will reveal more about the world and life if we have better measuring tools. Being precise is essential to understanding many parts of life.

Why is it easier to cut meat with a sharp knife than with a blunt knife​

Answers

Answer:

because the knife is sharp

Answer:

Pressure is inversely proportional to the area of the surface. While a blunt knife has more area coming in contact than a sharp knife and the pressure exerted by the blunt knife will be less as compared to that of a sharp knife. Therefore it is easier to cut with a sharp knife.

A 130 N horizontal force keeps a 30 kg chair moving at a constant velocity. Find the coefficient of kinetic friction between the chair and the floor.

Answers

The coefficient of kinetic friction between the chair and the floor is 0.44.

Given the following data:

Horizontal force = 130 NMass of chair = 30 kg

We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 [tex]m/s^2[/tex]

To find coefficient of kinetic friction between the chair and the floor:

Mathematically, the coefficient of kinetic friction between two objects is given by the formula;

[tex]u = \frac{F_k}{mg}\\\\u = \frac{130}{30[9.8]}\\\\u = \frac{130}{294}[/tex]

Coefficient of kinetic friction, u = 0.44.

what the kinetic energy quantities in calculation pls help me​

Answers

Answer:

KE = 0.5 * m * v², where: m - mass, v - velocity.

Explanation:

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

2. Both stretching and constricting exercises are important for muscle health.
A.

B.

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 truck brakes from 15 m/s to 2 m/s in 15 seconds. What is its acceleration?

Answers

If we take v=u+at and our given values are:

v=final velocity 20m/s

u=initial velocity 15m/s

a=acceleration

t=time 5sec

we plug those into our equation:

20m/s=15m/s+a(5s)

now we just rearrange to solve for acceleration.

(5m/s)/(5s)=a

a=1m/s^2

Why can’t you compress gas but you cannot compress a liquid

Answers

There is no space between the individual particles, so they cannot pack together. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.
