When the pole is lifted, it could be able to supply energy to the pole - vaulter much like that of a spring that launches the pole vaulter upwards.

We know that the pole vault is one of the popular sports especially in the Unites States. It is a competition that takes place even at the Olympic level and has a lot of athletes that do compete in the competition.

We know that as the pole unbends, it creates force that launches the pole-vaulter up and over the bar using your knowledge of potential and kinetic energy.

This implies that there are a series of energy conversions that do take place in the pole vault as it is in operation as we can see here. Thus, it is the series of the energy conversions that takes place in the pole vaulting that enables the athlete to be able to launch high in the game as we see.

According to the question the tension in rope 2 is 7.46 N.

Tension is a force that acts along the length of a material, such as a rope or wire. It is a force caused by the stretching or pulling of the material. In physics, tension is related to the force needed to create a change in the length of a material. It is measured in newtons (N). The amount of tension in a material depends on the material’s elasticity and the amount of force applied. Tension is different from compression, which is a force that acts to reduce the length of a material. Tension is also related to the concept of stress, which is the amount of force per unit area of a material.

The tension in rope 2 can be calculated using the equation:

T2 = (m1*g*μ)/(m2+m1)

where m1 is the mass of sled A, m2 is the mass of sled B, g is the acceleration due to gravity (9.81 m/s2), and μ is the coefficient of friction between the sleds and the snow.

Therefore, the tension in rope 2 is calculated as follows:

T2 = (100kg * 9.81 m/s2 * 0.09) / (80kg + 100kg)

T2 = 7.46 N

Therefore, the tension in rope 2 is 7.46 N.

Answer:

Explanation:

Answer:

What are Newton's laws of motion? Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration.

The torque of force A about point O can be calculated using the cross product of the position vector from O to the point of application of force A and the force vector A.

Torque is a measure of the rotational force acting on an object. It depends on the magnitude of the force and the distance from the point of rotation. In this case, to calculate the torque of force A about point O, we need to find the cross product of the position vector from O to the point where force A is applied and the force vector A. The cross product gives a vector that is perpendicular to both the position vector and the force vector, representing the rotational effect. The magnitude of this vector represents the torque, and its direction follows the right-hand rule.

Answer:

Alright, so mass is a property of a physical body. During physical changes, such as acceleration, force, etc, the mass stays the same since we are not affecting its physical shape, just where it is physics wise. So yeah mass is conserved during a physical change.

Explanation:

Hopefully this helped, if not HMU and I will get u a better answer

-have a great day! :)

In a physical change the mass remains the same before and after the process, then it is said as the mass is conserved and mass is only conserved in the isolated system.

A system that is isolated from its environment is one that does not communicate with it. As a result, no matter what changes or chemical reactions take place in that isolated system, the mass will remain constant; even if the final state may differ from the initial state, there can be no more or less mass than there was before the change or reaction.

The understanding that substances do not actually vanish as a result of a reaction, despite what might appear to be the case, but rather change into another material of equal mass, was made possible by the law of conservation of mass, which was essential to the development of chemistry.

dang, you are really trying to get everyone to do your heavy lifting lol.

I'll do coal. and maybe a little more.

Explanation:

Coal What is it?

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.

Coal How we obtain it:

Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Coal Pros:

Coal is plentiful in many places and it is easy to access through mining, so people rely on it to produce energy. Coal is easy to store. Once it is mined it can be safely stored with no hazard of fire or explosion like there is with gas or oil. It is relatively easy and inexpensive to convert coal into energy.

Coal Cons:

Coal is nonrenewable.  Coal contains the most CO2 per BTU, the largest contributor to global warming.  Severe environmental, social, and health, and safety impacts of coal mining.  The devastation of the environment around coal mines is heavy.  High cost of transporting coal to centralized power plants. Coal is really dirty and not good.

Solar What is it?

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.

Solar How we obtain it:

Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

Solar Pros:

It's clean energy. Solar power is pollution-free and causes no greenhouse gases to be emitted after installation.  It has reduced dependence on foreign oil and fossil fuels.  It is renewable clean power that is available every day of the year, even cloudy days produce some power.  It gives a return on investment unlike paying for utility bills.

Solar Cons:

Solar doesn't work at night. Solar panels are not attractive. You can't install a home solar system yourself. My roof isn't right for solar. Solar hurts the environment. Not all solar panels are high quality.

The minimum distance 'd' between the cars to avoid a collision is either 45 feet if Car B stops instantly or 645 feet if Car B takes 10 seconds to come to a stop after the driver applies the brakes.

To determine the minimum distance 'd' between the cars to avoid a collision, we need to consider the time it takes for both cars to come to a stop after the driver of Car B applies the brakes.

1. Car B:

  - Initial velocity: 60 ft/s

  - Deceleration: -12 ft/s² (negative because it's decelerating)

  - Time to come to a stop: Unknown, denoted as 'tB'

2. Car A:

  - Initial velocity: 60 ft/s

  - Deceleration: -15 ft/s^2 (negative because it's decelerating)

  - Reaction time: 0.75 s

  - Time to come to a stop: 'tB' + Reaction time

Since both cars come to a stop, we can equate their respective distances traveled to zero using the kinematic equation:

Distance = Initial velocity × Time + 0.5 × Acceleration × Time²

For Car B:

0 = 60 ft/s × tB + 0.5 × (-12 ft/s²) × tB²

Simplifying this equation will give us the time 'tB' for Car B to come to a stop.

For Car A:

0 = 60 ft/s × (tB + 0.75 s) + 0.5 × (-15 ft/s²) × (tB + 0.75 s)²

Simplifying this equation will give us the total time for Car A to come to a stop.

To find the minimum distance 'd' between the cars, we need to determine the value of 'd' when both cars come to a stop simultaneously. This occurs when the total time for Car A to stop is equal to 'tB'. Substitute this value into the equation:

d = 60 ft/s × (tB + 0.75 s)

0 = 60tB - 6tB²

This is a quadratic equation in terms of 'tB'. Rearranging the equation:

6tB² - 60tB = 0

Factor out a common term of 6tB:

6tB(tB - 10) = 0

This equation will be satisfied when either 6tB = 0 or tB - 10 = 0:

1) 6tB = 0

  tB = 0

2) tB - 10 = 0

  tB = 10

We have two possible solutions for 'tB': tB = 0 and tB = 10.

Now let's substitute these values into the equation for 'd' to find the minimum distance:

For tB = 0:

d = 60 ft/s × (0 + 0.75 s) = 45 ft

For tB = 10:

d = 60 ft/s × (10 + 0.75 s) = 645 ft

Therefore, the minimum distance 'd' between the cars to avoid a collision is 45 feet when Car B stops instantly, or 645 feet when Car B takes 10 seconds to stop.

Explanation:

In the Newton's ring experiment, the diameter of the 4th dark ring is 0.30 cm and the diameter of the 10th dark ring is 0.62 cm. We can use this information to find the diameter of the 15th dark ring and calculate the wavelength of the light.

a) To find the diameter of the 15th dark ring, we can use the formula for the diameter of the nth dark ring:

d_n = sqrt(n * λ * R)

where d_n is the diameter of the nth dark ring, n is the order of the ring, λ is the wavelength of the light, and R is the radius of curvature of the lens.

Since we want to find the diameter of the 15th dark ring, we can substitute n = 15 into the formula and solve for d_15:

d_15 = sqrt(15 * λ * R)

b) To calculate the wavelength of the light, we can use the formula:

λ = (\(d_10^2 - d_4^2\)) / (\(10^2 - 4^2\))

where d_10 is the diameter of the 10th dark ring and d_4 is the diameter of the 4th dark ring.

Substituting the given values, we have:

λ = (\(0.62^2 - 0.30^2\)) / (\(10^2 - 4^2\))

Simplifying this expression will give us the value of the wavelength of the light used in the experiment.
