The amount of movement of the particles depends on the amount of _________ acting on them and their relationship to other atoms.

Physics
1 answer:
Liula [17]4 years ago
4 0

Answer: The amount of movement of the particles depends on the amount of <u>force</u> acting on them and their relationship to other atoms.

Explanation:

The inter-atomic force determines the inter-atomic distance which governs the amount of movement of the particles.

For example in solids, the inter-atomic force is stronger and hence, the distance between any atoms is very very small which restricts the movement of the particles. On the other hand, in case of liquids and gases, the inter-atomic forces are not very strong and there is more distance between the atoms which allows free movement of particles.

(forces and motion) explain in 3-2 sentences why acceleration is interesting.
Luden [163]

Answer:

  • Acceleration is a vector and is the rate at which an object changes its velocity. Acceleration is not going fast.
  • If a person is moving fast but not changing speed, he is not accelerating.
  • The person or object has to be going fast sometimes, faster sometimes, or slower sometimes.

An airplane is initially flying horizontally (not gaining or losing altitude), and heading exactly North. Suppose that the earth
yanalaym [24]

Note: The answer choices are :

a) Increased

b) Decreased

c) stayed the same

Answer:

The correct option is Increased

The magnitude of the electric field potential difference between the wingtips increases.

Explanation:

The magnitude of the electric potential difference is the induced emf and is given by the equation:

emf = l (v \times B)

where l = length

v = velocity

B = magnetic field

As the altitude of the airplane increases, the magnetic flux becomes stronger, the speed of the airplane becomes perpendicular to the magnetic field, i.e. v \times B = vB sin90 = vB\\ ,

the induced emf = vlB, and thus increases.

The magnitude of the electric field potential difference between the wingtips increases

A 70 kg hunter, standing on frictionless ice, shoots a 42 g bullet horizontally at a speed of 590 m/s . Part A Part complete Wha
Kisachek [45]

Answer:

The recoil velocity is 0.354 m/s.

Explanation:

Given that,

Mass of hunter = 70 kg

Mass of bullet = 42 g = 0.042 kg

Speed of bullet = 590 m/s

We need to calculate the recoil speed of hunter

Using conservation of momentum

m_{1}u_{1}+m_{2}u_{2}=m_{1}v_{1}+m_{2}v_{2}

Where,m_{1} = mass of hunter

m_{2} = mass of bullet

u = initial velocity

v = recoil velocity

Put the value in the equation

0+0=70\times v_{1}+0.042\times590

v_{1}=-\dfrac{0.042\times590}{70}

v=-0.354\ m/s

Hence, The recoil velocity is 0.354 m/s.

a crate is being lifted into a truck. if it is moved with a 2470n force and 3650 j of work is done , then how far is the crate b
SVEN [57.7K]

Answer:

The crate was being lifted by a height of 1.48 meters.

Explanation:

In an attempt o move a crate;

Force applied = 2470 N

Work done by the force = 3650 J

We know that the work done is defined as the force used to move an object to a distance.

Given the Force used and the work done by that Force, we need to find out the distance the crate was lifted to.

Work done is defined as:

Work = Force*distance covered in the direction of the force

3650 = 2470*distance

distance = 3650/2470

distance = 1.48 meters
