Answer:

This is Newton’s third law (forces due to friction). There would be 15N being pushed back at Jane.

Explanation:

Newton’s third law states that for every action there is an equal and opposite reaction. So if Jane pushed with a force of 15N, 15N would be pushed back at her. Hope this helps! :)

Explanation:

Lifting a saturated package causes it to expand and cool, resulting in vapour condensation. Condensation will release latent heat, partially counteracting the cooling. As a result, a saturated parcel's adiabatic lapse rate is smaller than an unsaturated parcel's.

Because moist air ascending condenses off its water vapour, the moist adiabatic lapse rate is lower than the dry adiabatic lapse rate (once saturation is attained). The air is considered to be saturated when the dew point temperature and air temperature are identical.

soccer

Explanation:

soccer can inprove your health because you use all parts of your body playing it. You use your legs because you are running and you use your arms for doing throw ins. Soccer is also good for you because you are not playing for too long. Usually one soccer game is only 1 hour.

Answer:

This is to say that the vertical velocity changes by 9.8 m/s each second and the horizontal velocity never changes. This is indeed consistent with the fact that there is a vertical force acting upon a projectile but no horizontal force.

Explanation:

Answer:

ok

Explanation:

solid- molecules are close together and vibrating

liquid - molecules are loser, faster moving and take the shape of its container

gas- fast moving molecules and take whatever shape they want (like a room or the air outside)

Explanation:

Solids: The inter-molecular attraction force is the highest and the inter-molecular distance is the least. Solids have definite shape and volume.

Liquids: The inter-molecular attraction force is less than that of solids and the inter-molecular distance is more than solids. Liquids have definite volume but no definite shape.

Gases: The inter-molecular attraction force is the least and the inter-molecular distance is the highest. Gases have no definite shape or volume.

Velocity:

Velocity is change in displacement with respect to time:

[tex]\frac{\Delta x}{\Delta t}[/tex]

Analysing the units, meters (displacement) and seconds (time) are basic units:

[tex]\frac{m}{s}[/tex]

Therefore the unit of velocity is m/s

Force:

Newton's second law of motion:

[tex]F = ma[/tex]

Kilogram (mass) is a basic unit, and accelerations unit can be found using the equation:

[tex]a=\frac{\Delta v}{\Delta t}[/tex]

Analysing the units:

[tex]\frac{\frac{m}{s}}{s}=\frac{m}{s^2}[/tex]

Therefore, the unit of force is:

[tex]kg\frac{m}{s^2}[/tex]

Pressure:

Pressure is given by the equation:

[tex]P=\frac{F}{S}[/tex] where S is area of effect, F is force

Area for a basic rectangle (geometric shape is arbitrary for dimensional analysis) is found by multiplying two lengths:

[tex][l^2]=m^2[/tex], the unit of area

Dividing the aforementioned unit of force by the unit of area:

[tex]\frac{kg\frac{m}{s^2}}{m^2}=\frac{kg}{ms^2}[/tex], the unit of pressure

Work:

Work is given by the equation:

[tex]W=\vec{F}\cdot \vec{x}[/tex], (dot product may be assumed as normal multiplication for the purposes of unit analysis)

Knowing displacement's (x) unit is m:

[tex][W]=\frac{kgm}{s^2}m=\frac{kgm^2}{s^2}[/tex], the unit of work.

Answer:

60 m

Explanation:  

After 3 seconds of travel at 20 m/s, the projectile is 3·20 = 60 meters horizontally from the cannon.

__

The vertical height after 3 seconds is 0.9 m, so the straight-line distance from cannon to target is √(60^2 +0.9^2) ≈ 60.007 meters.

Answer:

0.28m/s²

Explanation:

Force = mass•acceleration

F = m•a

50 = 176•a Divide both sides by 176:

50/176 = a ≈ 0.28 m/s²

If an object has a balanced force on it, there is a possibility that the object may be in a position i.e. there is no change in speed and direction of the body.

If the forces acting on an object is balanced, it means that the net force acting on the body is zero.

According to Newton's law of motion, an object will continue in a state of motion in a straight line unless acted upon by an external force.

This external force might be a balanced or unbalanced force. Hence if an object has a balanced force on it, there is a possibility that the object may be in a position i.e. there is no change in speed and direction of the body.

5- when temperature increase speed of sound will increase

1. The speed of sound at the lowest temperature in the image is 330.4 m/s.

2. The speed of sound at the highest temperature in the image is 358.0 m/s.

3. The temperature at which the speed of sound is slowest is -1°C.

4. The temperature at which the speed of sound is fastest is 45°C.

5. Yes, temperature affects the speed of sound.

The image shows the relationship between temperature and speed of sound in air. The x-axis of the graph shows the temperature in degrees Celsius, and the y-axis shows the speed of sound in meters per second. The line on the graph shows that the speed of sound increases with temperature. For every 1 degree Celsius increase in temperature, the speed of sound increases by about 0.6 m/s.

The speed of sound in air is also affected by other factors, such as humidity and air pressure. However, temperature is the most important factor affecting the speed of sound.

The speed of sound at the lowest temperature in the image is 330.4 m/s, which is at -1°C.

The speed of sound at the highest temperature in the image is 358.0 m/s, which is at 45°C.

The temperature at which the speed of sound is slowest is -1°C.

The temperature at which the speed of sound is fastest is 45°C.

Yes, temperature affects the speed of sound. The speed of sound increases with temperature. This is because the molecules of a medium vibrate faster at higher temperatures, and this allows sound waves to travel more quickly.

Answer:

The size of the frictional force is 577 N.

Explanation:

Frictional forces are exerted every time you have two surfaces sliding across one another. Friction depends on:

There are two types of friction:

Now let's attack the problem:

First, you have to write the data down:

[tex]\bullet \quad m= 63\,kg\\\\\bullet \quad F= 577\,N\\\\\bullet \quad v= 2.4\,m/s[/tex]

If the boy and the sled moves on constant velocity, Newton's First Law Of Motion states that the net force acting on them must be zero:

[tex]F_{net}=0[/tex]

Applying Newton's Second Law Of Motion, we get:

[tex]F-f_d=0[/tex]

which means that:

[tex]F=f_d[/tex]

In other words, the dynamic frictional force equals the force that moves the boy and sled. So we may write:

[tex]\boxed{f_d=577\,N}[/tex]

Conclusion: the size of the (dynamic) frictional force is 577 N.

Explanation:

Because It is a common technique and lots of athletes practice injured so she will be fine.

By working on the given plan, Angelica can injure herself since she will not feel pain. The correct option is A.

A sprain takes place when your ankle is compelled to move out of its regular place, causing one or more of the ligaments in your ankle to stretch, partially tear, or completely tear.

A sprained ankle can be caused by a fall that causes your ankle to twist. Landing on your foot awkwardly after jumping or pivoting.

You should avoid strenuous exercises, such as running, until the pain and swelling have subsided, but you should keep moving so that the muscles and ankle do not stiffen. Once your ankle is less painful, begin some gentle exercises.

As she is having ankle sprain, and she is planning to take pain killers and start to work out, this can cause her even more problem as she will not feel any pain.

Thus, the correct option is A.

Explanation:

They had demoted Pluto on the basis of the discovery of Eris. They also discovered that Eris had a moon. It was thought to be much bigger than Pluto. That turned out not to be true. So having accepted Eris as a planet, they had to consider carefully what to do about Pluto. It has a gravitational constant of 0.82 m/s^2 which is 8.4% of that of our gravitational pull. and slightly more than Pluto.

Later data showed that these two  objects in space were more like twins and that's what shook up the definition of a planet. You can't demote one and not the other.
