At sea level, water boils at 100 degrees celcius and methane boiled at -161 degrees celcius. Which of these substances has a stronger force of attraction between its particles? Explain your answer

Answers

Answer 1

Answer: Water has stronger force of attraction between its particles because methane is gas and its particles are further from itself.

A 4.0 kg bucket of water is raised from a wellby a rope.
The acceleration of gravity is 9.81 m/s?.
If the upward acceleration of the bucket is
2.8 m/s², find the force exerted by the rope
on the bucket of water.
1. 69.658
2. 52.84
3. 85.318
4. 70.86
5. 84.429

Answers

Explanation:

Draw a free body diagram of the bucket. There are two forces:

Tension force T pulling up.

Weight force mg pulling down.

Sum of forces in the y direction:

∑F = ma

T − mg = ma

T = mg + ma

T = m (g + a)

Given m = 4.0 kg, g = 9.81 m/s², and a = 2.8 m/s²:

T = (4.0 kg) (9.81 m/s² + 2.8 m/s²)

T = 50.44 N

If a substance conducts heat easily, it is considered to be agood insulator.bad substance.good conductor.poor conductor.

Answers

If a Substance conducts heat easily then it is considered a good conductor, since the electrons can move freely within the substance.

I think the answer is good conductor!

A baseball falling toward a player's glove gains _____ energy and loses _____ energy. A. potential; kinetic B. kinetic; potential C. kinetic; chemical D. chemical; potential

Answers

Answer:

I think it's B it can not be C or D because it has nothing to do with chemical energy

Answer:

Your answer is B

Explanation:

When a ball falls it is gaining kinetic energy because it gains speed as it falls.Since its gaining kinetic energy it loses potential energy so ur answer is B :) hope it helps

What is the period of vibration for a wave with a frequency of 100 hertz?

Answers

The number of back-and-forth vibrations in a unit of time is an object's frequency. A complete back-and-forth vibration is one cycle. 1 Hz is one vibration or wave cycle per second!

Answer:

100 seconds

A squirrel (mass 0.9 kg) is running across the road at a speed 4.0 m/s. What is thesquirrel's kinetic energy?

Answers

The kinetic energy of the squirrel with a mass of 0.9 Kg running with a speed of 4 m/s is 7.5 J.

What is kinetic energy?

Kinetic energy of an object is a form of energy generated by virtue of the motion of the object. Kinetic energy is dependent on the mass and velocity of the body.

When a body starts to move its potential energy starts to convert to kinetic energy and the kinetic energy will be maximum at the highest speed. When the object slow down and pause in a position it gains potential energy again.

The kinetic energy KE = 1/2 mv²

Given mass = 0.9 Kg

velocity = 4 m/s.

KE = 1/2 0.9 Kg × 4² m/s

= 7.5 J

Therefore, the kinetic energy of the squirrel is 7.5 J.
