Explain the energy needed for a liquid to evaporate into gas

Answers

As the molecules at the surface of a liquid absorb heat, they begin to move around more quickly. This gives them the energy to break the bonds that connect them to other water molecules. When the molecules are moving fast enough, they are able to "escape." They leave the surface of the liquid as gas molecules

Suppose that the net external force (push minus friction) exerted on a lawnmower is 51 N. parallel to the ground. The mass of the mower is 24 kg. What is its acceleration?

Answers

Answer:

2.125 m/s^2

Explanation:

Use Newton's second law: Force equals mass times acceleration, F = ma. You know the force (51 N) and you know the mass of the mower (24 kg). Remembering that a Newton is the same as kg-m/s2, solve for acceleration:

F = ma

51 kg-m/s2 = 24 kg * a

2.125 m/s2 =a

If a net external force of 51N is extorted on a 24kg lawnmower parallel to the ground, the acceleration of the mower will be 2.125 m/s².

Given the data in the question;

Net External Force; [tex]F = 51N[/tex]

Mass of the Mower; [tex]m = 24kg[/tex]

Acceleration; [tex]a = ?[/tex]

To determine the acceleration of the mower, we make use of the equation from the Newton's Second Law of Motion:

[tex]F = m\ * \ a[/tex]

Where F is the force exerted, m is the mass and a is the acceleration.

But then, we know that; ( A newton is the same thing as  [tex]1 kg.m/s^2[/tex] )

Hence, Our Net External Force; [tex]F = 51kg.m/s^2[/tex]

We substitute our values into the equation to find acceleration "a"

[tex]51kg.m/s^2 = 24kg\ *\ a\\\\a = \frac{51kg.m/s^2}{24kg} \\\\a = 2.125 m/s^2[/tex]

Therefore, If a net external force of 51N is extorted on a 24kg lawnmower parallel to the ground, the acceleration of the mower will be 2.125 m/s².

Answers

Answer:

The answer is option A

Explanation:

In order to find the distance covered we use the formula

distance = velocity × time

From the question

velocity = 1.85 km/hr

time = 0.6 hours

We have

distance = 1.85 × 0.6

We have the final answer as

1.11 km

A hockey stick strikes a hockey puck of mass 0.17 kg. If the force exterted on the hockey puck is 35.0 N and there is a force of friction of 2.7 N opposing the motion. what is the acceleration of the hockey puck?

Choices:
0.0054 m/s^2
0.005 m/s^2
200 m/s^2
190 m/s^2

Answers

Answer:

[tex]a=190\ m/s^2[/tex]

Explanation:

Mass of a hockey puck, m = 0.17 kg

Force exerted by the hockey puck, F' = 35 N

The force of friction, f = 2.7 N

We need to find the acceleration of the hockey puck.

Net force, F=F'-f

F=35-2.7

F=32.3 N

Now, using second law of motion,

F = ma

a is the acceleration of the hockey puck

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{32.3}{0.17}\\\\a=190\ m/s^2[/tex]

So, the acceleration of the hockey puck is [tex]190\ m/s^2[/tex].

The magnitude of acceleration of the hockey puck is 190 m/s² .

Given data:

The mass of hockey puck is, m = 0.17 kg.

the magnitude of external force on the puck is, F = 35.0 N.

The magnitude of force of friction is, f = 2.7 N.

We need to find the net force acting on the puck first. For that consider the applied force in the x-direction. Then net force is,

F' = F - f

Solving as,

F' = 35.0 - 2.7

F' = 32.3 N

Now, use the Newton's Second law to obtain the magnitude of acceleration (a) as,

F' = ma

Solving as,

32.3 = 0.17 (a)

a = 32.3/0.17

a = 190 m/s²

Thus, we can conclude that the magnitude of acceleration of the hockey puck is 190 m/s² .

Which statement about mass and inertia is not true?
A. Both mass and inertia play a role in Newton's first law.

B.Mass is a quantitative measurement of inertia.

C. The tendency of an object to remain at rest results from a property called inertia.

D.Newton's first law is sometimes called the relative inertia law.""​

Answers

Answer:

D. Newton's first law is sometimes called the relative inertia law.

Explanation:

Newton's first law of motion states that an object at rest will stay at rest and that in motion will stay in motion with same speed and in the same direction unless an unbalanced force acts on it. It is also called the law inertia. Mass and inertia play a role in this law because mass is a quantity that mainly depends on inertia in that a body with more inertial will exhibit more mass.
