1. The kinetic energy of the truck is 1959940.8 J

2. The kinetic energy of the car is 463037.04 J

The kinetic energy of the 6000 Kg truck can be obtained as follow:

KE = ½mv²

KE = ½ × 6000 × 25.56²

KE = 1959940.8 J

Thus, the kinetic energy is 1959940.8 J

The kinetic energy of the 6000 Kg truck can be obtained as follow:

KE = ½mv²

KE = ½ × 1200 × 27.78²

KE = 463037.04 J

Thus, the kinetic energy is 463037.04 J

Answer:

The maximum depth of the water at the place is 6.0 meters.

Given the tidal range and average depth, it is to be noted that the maximum depth of the water at the place, is 6.0 meters.

The tidal range is the successive difference between tide highs and lows, which is a sinusoidal pattern. On the basis of the above, it is correct to state that the tidal range is twice of the amplitude of the tide level.

That is:

The Amplitude of the tide, A = 2.0/2m = 1m

The maximum depth at the place, therefore, is given as:


D\(_{max}\) = A + D\(_{ave}\)

Hence,

D\(_{max}\) = 1.0 + 5.0 = 6.0

Thus, it is correct to state that the Maximum Depth (D\(_{max}\)) = 6.0 Meters.

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Yes, I noticed that a magnet could be used to move the paper clip without touching it.

It is  similar to the floating plant because both processes involve a force acting on an object without having a direct physical contact.

The force acting on the paper clip is described as the magnetic force,

The claim can be made that magnets could  move an object  without physical contact by using the magnetic force to exert a force on the object.

A magnetic field is described as a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

In this case , the magnetic force arose due to the interaction between the magnetic fields of the magnet and the paper clip.

The magnet has a magnetic field around it, which exerts a force on any nearby magnetic material, such as the paper clip.

Answer:Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

energy = (1/2)*m*(v^2)

Answer:

net force will be 0N and the rope will not accelerate.

Explanation:

to calculate net force, you need to find the difference between the two forces, which would be 5000N - 5000N = 0N

since there is no net force, there is no movement of the rope.

If you have any questions ask me please! :)

The kinetic Energy of the bottle falling from a height of 0.8m for different masses of (0.125,0.250,0.375,0.500)kg is (1,2,3,4) kgm*2/s*2 respectively.

Let's calculate the kinetic energy for different masses having a velocity of 4m/s in each case,

Using Formula:

K.E=\(1/2mv^{2}\)

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.125)(4)^{2}\)

K.E=\(1/2(0.125)(16)\)

K.E=1/2(2)

K.E=1

When the mass of the bottle is 0.250 kg, the Kinetic Energy  is

K.E=\(1/2(0.250)(4)^{2}\)

K.E=1/2(0.125)(16)

K.E=1/2(4)

K.E=2

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.375)(4)^{2}\)

K.E=1/2(0.375)(16)

K.E=1/2(6)

K.E=3

When the mass of the bottle is 0.500 kg, the Kinetic Energy  is

K.E=\(1/2(0.500)(4)^{2}\)

K.E=1/2(0.500)(16)

K.E=1/2(8)

K.E=4

Now we can calculate the change in kinetic energy (ΔKE):

ΔKE = KE(final) - KE(initial)

= 4 kg m*2/s*2 - 1 kg m*2/s*2

= 3 kg m*2/s*2

Hydroelectric energy would be the best alternative energy source for a house in Alaska. While solar energy can be a good source of electricity in many areas, it is not a reliable source of energy in Alaska due to the long periods of darkness during the winter months. On the other hand, hydroelectric energy can be generated continuously as long as there is a water source, such as a river or stream, available to power the turbines. This makes it a more reliable and consistent source of energy in a place like Alaska where the sun is not always shining. Additionally, hydroelectric energy is a clean and renewable energy source, making it a good choice for those who are looking to reduce their carbon footprint.

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.

Please note that this arrangement is based on the internal organization of the circulatory system, with consideration given to the hierarchical structure and function of each component.
