Explanation: it gets dimmer becuase less light......

As it is observed the distance between the rest position and the crest of a light wave decreases, and the light becomes dimmer, therefore the correct answer is option B.

It can be understood in terms of the distance between any two similar successive points across any wave for example wavelength can be calculated by measuring the distance between any two successive crests.

C = λν

As given in the , it is observed the distance between the rest position and the crest of a light wave decreases,

The right response is option B since it can be seen that when the distance between the rest position and the crest of a light wave decreases, the light becomes dimmer.

Answer:

The estimated braking force needed to stop the lorry is zero, based on the given information and calculations. However, it's important to note that this result is likely not accurate, as some force is required to stop a moving object. It's possible that additional information or calculations are needed to obtain a more realistic estimate of the braking force.

Explanation:

To estimate the braking force needed to stop the lorry, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).

In this case, the lorry decelerates uniformly, so the acceleration is constant. The initial velocity is assumed to be zero since the lorry comes to a stop. The final velocity is also zero. Therefore, we can use the equation:

Final velocity squared (vf^2) = Initial velocity squared (vi^2) + 2 * acceleration (a) * distance (d)

Since vi = 0 and vf = 0, the equation simplifies to:

0 = 0 + 2 * a * d

Solving for acceleration (a), we have:

2 * a * d = 0

a = 0

Since the acceleration is zero, it means that the braking force needed to stop the lorry is also zero. This is likely not an accurate result as some force is required to stop the lorry. It's possible that additional information or calculations are needed to accurately estimate the braking force.

The braking force required to stop a 6371 kg lorry after spotting a hazard and applying the brakes is what the question is asking for. The lorry decelerates uniformly and comes to a stop 60 meters after the brakes are applied.

The following steps will guide you on how to calculate the braking force:

Step 1: Determine the mass of the lorry which is 6371 kg. This will be denoted as m.

Step 2: Determine the distance travelled by the lorry, which is 60 m.

Step 3: Determine the time taken by the lorry to stop. This can be done by using the formula for uniform deceleration, which is a = (v-u)/t where v is the final velocity, u is the initial velocity and a is the uniform deceleration. Since the lorry comes to a stop, its final velocity is zero and its initial velocity is unknown.

However, we can assume that the lorry was initially travelling at a constant speed before spotting the hazard. Therefore, we can assume that the initial velocity was equal to the average velocity of the lorry before the brakes were applied.

This can be calculated using the formula v = d/t where d is the distance travelled and t is the time taken. The average velocity can therefore be calculated as follows: v = d/t = 60 m/t

Step 4: Rearrange the formula for uniform deceleration, a = (v-u)/t, to find u which is the initial velocity. Since the lorry comes to a stop, we know that v = 0.

Therefore: u = v - at where a is the uniform deceleration and t is the time taken to stop which is also equal to the time taken for the lorry to travel the distance of 60 meters. Substituting for v, we get: u = - at

Step 5: Calculate the acceleration of the lorry using the formula a = (v-u)/t. Since the final velocity is zero, we get: a = -u/t = -(-at)/t = a The acceleration is negative since the lorry is decelerating.

Step 6: Calculate the braking force using the formula F = ma where F is the braking force and m is the mass of the lorry. Therefore: F = ma = (-ma) since a is negative = (-6371 kg) (a) Therefore, the braking force required to stop the lorry is -6371a N where a is the uniform deceleration calculated in Step 5.

Explanation:

Curling is a sport in which players slide stones across a  distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side.  There are two  brigades. Each  platoon is trying to keep the other  platoon's  monuments down from the target by knocking their  monuments out of the way.

Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object."  This relates to the formula F =  ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

Answer: (B) 4 Seconds

Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)

Answer : B. The sjydriver has the fastest speed at 4second.

What is air resistances ?

--Air resistance is a type of friction force.

-- Air resistance, there are not two solid surfaces in contact.

-- Air resistance is the frictional force acting on an object and the air around them.

--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.

Concept Used

-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.

-- A person’s weight force will always stay the same.

-- The weight force of the person will equal their air resistance.

-- This would make the skydiver travel at constant speed.

--To travel at constant speed forces have to be equal to zero.

--This constant speed is called terminal velocity

The work input = Fi × di

To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:

Work Input = Force × Distance × cosθ

Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:

Work Input = Force × Distance

For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:

Work Input = 50 N × 10 m × cos(0°) = 500 Joules

Answer: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows: Heart, Blood Vessels, Arteries, Veins, and Capillaries.

Explanation: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows:

Heart: The heart is a vital organ responsible for pumping oxygenated blood to the body and deoxygenated blood to the lungs. It consists of chambers (atria and ventricles) and valves that regulate blood flow.

Blood Vessels: Blood vessels form a network of tubes that transport blood throughout the body. They can be classified into three types: arteries, veins, and capillaries.

Arteries: Arteries are thick-walled blood vessels that carry oxygenated blood away from the heart to various parts of the body.

Veins: Veins are blood vessels that transport deoxygenated blood from the body back to the heart. They have thinner walls compared to arteries and contain valves to prevent backflow.

Capillaries: Capillaries are tiny, thin-walled blood vessels that connect arteries and veins. They facilitate the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
