Which object has the greatest acceleration?
34
Ow
OZ

Answers

Answer 1
Answer:

Answer:

Y

Explanation:

The answer is y because,

W: (29-11)/6 = 3

X: (34-10)/12 =2

Y: (40-12)/7=4

Z= (28-20)/8=1

4 is greater then all, therefore the answer is Y
Answer 2
Answer:

Answer:

X

Explanation:

v=u+at but t is constant so

a=v-u

for x

a=29-10

a=19

which marks the greater acceleration

A group of students is measuring the change in momentum of an object. Which set of lab equipment would be most useful in measuring the momentum of an object?

Answers

Answer:

Ruler/tape and stopwatch

Weighing balance

Explanation:

Since for momentum, we're concerned with mainly mass and velocity of an object then you will need weighing balance calibrated with the most accurate unit (normally grams or kilograms). The weighing balance will therefore be useful in measuring mass. To obtain velocity, you need to get distance that an object moves and divide it by time taken for the movement. Therefore, a tape or rule will be useful in measuring distance moved in meters while stopwatch will help you get time taken which consequently you use to get velocity.

Is the earth getting heavier

Answers

Yes. Earth gets bigger every year. This cumbersome everyday mass accumulation can be charged toward nearly 100 weights of stars penetrating the Earth’s environment per day. 
Naturally yes, gravity plus the ever-increasing growing population of living organisms (human beings, animals, bugs, and etc.). Hope this helps!

​How are particles in motion and temperature related?​
How does a thermometer work?

​What are temperature scales, list them and give examples?

​Define volume.

Please try to answer them as best as you can. There are five questions, and I hope you will be able to answer them all. I really appreciate your help. Thank you!!!

Answers

1) How are particles in motion and temperature related?

Temperature is the measure of heat. The kinetic energy of particles in motion is determined by the temperature.  The higher the temperature, the higher the kinetic energy of the particles (basically, the hotter it is the faster the particles move).

2) How does a thermometer work?

A thermometer measures the average kinetic energy of the particles around the thermometer.  As seen in 1), the kinetic energy defines the temperature, so measuring the energy of the particles can show you the temperature of the object.

3) What are temperature scales, list them and give examples.

Temperature scales are pretty much systems with which we compare different temperatures.  The three widely used temperature scales today are Fahrenheit, Celsius, and Kelvin. All three are used in different countries and mainly for different purposes. Fahrenheit is used only in the United States and a few other countries around the world, while Celsius is excepted by nearly the entire rest of the world. Kelvin is used primarily in the scientific setting.

4) Define volume.

Volume is pretty much the amount of three-dimensional space an object or substance takes up.  For example, a liter is a unit of measurement of volume.  A two-liter bottle of soda means it contains the amount of soda that fills up 2-liters worth of three-dimensional space.

I hope this helped.
