Describe Kinetic Energy.​

Answer:

B; a path through a town with uprooted trees

Explanation:

took the quiz and got it right on edge2020!

The effect of tornadoes on the environment is a path through a town with uprooted trees. This, option B is correct.

It is the typical weather event that contains strong winds and leaves a path of destruction up to 50 miles long. It is also defined as the violently rotating column of air that touches the ground and is usually attached to a thunderstorm.

It is developed from a severe thunderstorm in warm, moist, and unstable air and extended up to 300 miles. The thunderstorms also generate heavy damage and devastate the environment in seconds and cause more fatalities.

A swirling, funnel-shaped, whirling wind is called a tornado and it is accompanied by hurricanes and storms. Strong tornadoes last for twenty minutes and the winds are between 200 mph to 300mph. The United States and Canada are mostly tornado-affecting countries.

The effect of tornadoes is a path through a town with uprooted trees and hence, the ideal solution is option B.

2) Some energy was transformed to other forms. (This question)

3) 3.24 J

4) 45 J

5) 1020 J

Explanation:

100%

Answer:

d = 120 [m]

Explanation:

In order to solve this problem, we must use the theorem of work and energy conservation. Where the energy in the final state (when the skater stops) is equal to the sum of the mechanical energy in the initial state plus the work done on the skater in the initial state.

The mechanical energy is equal to the sum of the potential energy plus the kinetic energy.  As the track is horizontal there is no unevenness, in this way, there is no potential energy.

E₁ + W₁₋₂ = E₂

where:

E₁  = mechanical energy in the initial state [J] (units of Joules)

W₁₋₂ = work done between the states 1 and 2 [J]

E₂  = mechanical energy in the final state = 0

E₁ = Ek = kinetic energy [J]

E₁ = 0.5*m*v²

where:

m = mass = 60 [kg]

v = initial velocity = 12 [m/s]

Now, the work done is given by the product of the friction force by the distance. In this case, the work is negative because the friction force is acting in opposite direction to the movement of the skater.

W₁₋₂ = -f*d

where:

f = friction force = 36 [N]

d = distance [m]

Now we have:

0.5*m*v² - (f*d) = 0

0.5*60*(12)² - (36*d) = 0

4320 = 36*d

d = 120 [m]

Answer:

80cm per second

Explanation:

Answer:

255 metres

Explanation:

The answer to the question is actually quite simple. Since the car goes for 3.4 seconds, and it goes 75 metres every second, the answer is just 3.4 multiplied by 75 Metres.

Answer:

You would have to find the friction force of the rubber block which would be found with the equation of Normal force (mass*gravity) times cooeficient of friction which would give 8.82 N for the amount of friction and because you need more force than 8.82 N (assuming gravity is 9.8)

We need to find the frictional force of the rubber block. This is the normal force (mass × gravity) multiplied by the coefficient of friction, which gives us a friction quantity of 8.82N. This is because it requires a force greater than 8.82N (Gravity is 9.8)

The mass of the ball is 5 kg and it is lifted 10 meters above the ground, its potential energy is 490 Joules.

What is Potential Energy?

Potential energy is the energy that an object possesses due to its position or condition. It is the energy that an object has stored within itself, ready to be converted into other forms of energy.

To calculate the potential energy of an object, we need to know its mass, the acceleration due to gravity, and its height above a reference point. The formula for potential energy is:

Potential Energy = Mass x Gravity x Height

where:

Mass is the mass of the object, in kilograms (kg)

Gravity is the acceleration due to gravity, which is approximately 9.8 m/s^2 on Earth

Height is the height of the object above a reference point, in meters (m)

If the mass of the ball is 5 kg, we can calculate its potential energy if we know its height above a reference point. For example, if the ball is lifted 10 meters above the ground, we can calculate its potential energy as:

Potential Energy = 5 kg x 9.8 m/s^2 x 10 m

Potential Energy = 490 Joules

Sir isaac Newton made a connection between the mass of an object and the distance between them.

According to Newton's law of universal gravitation, every object in the universe attracts each other with a force directly proportional to the product of the masses of the object and inversely proportional to the distance between the two objects.

[tex]F = \frac{Gm_1m_2}{R^2}[/tex]

where;

Centripetal acceleration  = ?

Solution:

The centripetal acceleration is the change in velocity of a body along a circular path with time.

It is mathematically expressed as;

         a = [tex]\frac{v^{2} }{r}[/tex]  

v is the velocity

r  = radius of path

           v  = [tex]\frac{2\pi r}{t}[/tex]  

  t is the time;

   Insert the parameters and solve for the velocity;

          v  = [tex]\frac{2 x \pi x 160}{36}[/tex]   = 27.9m/s

Now,

         acceleration  = [tex]\frac{27.9^{2} }{160}[/tex]    = 4.88m/s²

The magnitude of the centripetal acceleration of the car is [tex]4.87 \;\rm m/s^{2}[/tex].

Given data:

The combined mass of race car and its driver is, m = 600 kg.

The radius of the circular track is, r = 160 m.

The time taken to cover one lap is, t = 36 s.

The velocity of the car while covering one complete lap of circular track is given as,

[tex]v = \dfrac{2 \pi r}{t}\\\\v = \dfrac{2 \pi \times 160}{36}\\\\v = 27.92 \;\rm m/s[/tex]

And the expression for the magnitude of centripetal acceleration is given as,

[tex]a=\dfrac{v^{2}}{r}\\\\a=\dfrac{27.92^{2}}{160}\\\\a=4.87 \;\rm m/s^{2}[/tex]

Thus, we can conclude that the magnitude of the centripetal acceleration of the car is [tex]4.87 \;\rm m/s^{2}[/tex].
