Use the work-energy theorem. The total work W performed on the car as it it slows to a stop is equal to the change in the car's kinetic energy ∆K. So

W = ∆K

W = 0 - 1/2 (1000 kg) (72 km/h)²

W = - (500 kg) (20 m/s)²

W = - 200,000 J = -2 × 10⁵ J

The closest answer would be C, but friction opposes the car's motion so the work would be negative.

Plasma osmolarity increases when you give a severely dehydrated person large amounts of pure water.

The electrolyte–water balance of the body is measured by plasma osmolality. This amount can be determined in a variety of ways, including measurement and computation.

Osmolality and osmolarity are two separate measurements that are used interchangeably in everyday situations.

When you are dehydrated, osmolality rises, and when you have too much fluid in your blood, it drops.

The way your body regulates osmolality is unique. When your body's osmolality rises, your body produces antidiuretic hormone.

Hence,plasma osmolarity increases when you give a severely dehydrated person large amounts of pure water.

Explanation:

It is called villi' in case of human beings.. That's it..

The finger-like outgrowths in the human intestine are called villi, and their main function is to absorb the digested food. Therefore, the option is (c) absorb the digested food.

The villi in the human intestine increase the surface area for absorption, allowing for more efficient uptake of nutrients from the digested food. They contain blood vessels and lymphatic vessels that absorb nutrients such as sugars, amino acids, and fatty acids. The nutrients are then transported to the liver and other parts of the body for use.

The function of villi in humans is to increase the surface area of the small intestine, which allows for more efficient absorption of nutrients from digested food.

Villi are finger-like projections that line the walls of the small intestine, and they are covered in tiny microvilli that further increase the surface area. The villi contain blood vessels and lymphatic vessels that absorb nutrients such as sugars, amino acids, and fatty acids from the digested food.

These nutrients are then transported to the liver and other parts of the body for use. Without villi, the surface area of the small intestine would be much smaller, and the body would not be able to absorb nutrients as efficiently. Hence, option C is correct.

When you are riding in a coaster car that is traveling at a constant speed, you only feel the downward force of gravity. But as the car speeds up or slows down, you feel pressed against your seat or the restraining bar. You feel this force because your inertia is separate from that of the coaster car.

Explanation:

If you touch a conductor through which electricity flows with an insulator, the likelihood of receiving a shock depends on several factors, including the voltage and current of the electrical source, the amount of insulation present, and how well the insulation is able to insulate from the electricity.

Insulators are materials that do not conduct electricity and are commonly used to provide a barrier between humans and electrical conductors to prevent electrical accidents. When an insulator is used to touch a conductor through which electricity flows, the insulator acts as a barrier and prevents the current from flowing through the material and into the body.

However, if the insulation is inadequate or damaged, or the voltage of the electrical source is high enough to overcome the insulating properties of the material, a shock can occur. The shock occurs when the current passes through the body, causing damage to organs, muscles, and nerves.

Therefore, it is important to ensure that proper insulation practices are followed when working with electrical conductors, and to use insulation materials that are sufficient to protect against the voltage and current levels of the electrical source being used. Generally, it is recommended to avoid touching electrical conductors altogether, as the risk of electrical accidents is always present.

No, you will not receive a shock if you touch a conductor through which electricity flows with an insulator. An insulator is a material that does not conduct electricity, meaning it does not allow the flow of electric current.

It has high resistance and acts as a barrier, preventing the transfer of electrons. Therefore, when you touch a conductor with an insulator, the insulator acts as a protective layer that blocks the flow of electric current and prevents it from reaching your body. As a result, you will not experience a shock. However, it is important to note that the effectiveness of the insulator in preventing a shock depends on its quality and condition. If the insulator is damaged or has a low resistance, it may not provide adequate protection, and there is a risk of electric shock. Additionally, it is crucial to follow safety protocols and avoid touching conductors or working with electricity unless you are trained and have the necessary knowledge and equipment to do so safely.

Answer:

Normal, Gravitational, Applied, Friction, and Tension

Explanation:

Because the sled is on the ground, or rather because it is on the earth, it will have a force of gravity, or its weight, pulling it down.

There is a normal force because the sled is not moving into the ground, so there needs to be a force pushing on the sled from the ground. Additionally, Newton's 3rd law states that for every action there is an equal but opposite reaction, if it's in equilibrium or not moving.

There will be an applied force since the child is pulling the sled and is applying a force to do so.

There will be a friction force that is pulling the sled opposite the direction it is moving, since it is on the ground that is presumably not fricitonless.

There will be a tension force pulling on the sled by the rope. However there is also a tension force pulling on the child's hand by the rope, meaning that these are internal forces and essentially balance out, but they are still there.

There is no air resistance force, or very little of it, since the object is not falling.

Answer:

The weight of an object is dependent upon the value of the acceleration of gravity.
