p = m v . The equation demonstrates that motion is directly related to a direction of motion (m) and rate (v). As a result, an object's momentum increases with increasing mass or velocity. The momentum of a large, swift object is larger than that of a small, slower object.

Here, mt denotes the truck's mass, and vt denotes its speed. Consequently, the truck's momentum is measured at 12 104 kg/m/s or 12 10 4 kg/m/s.. Angular momentum is a scalar quantity that represents the energy of motion in an object. Sometimes people mistake motion for force.

According to conservation of momentum, the product of mass and velocity is constant.

Since the velocity of the second mass is greater than that of the first mass

This is possible if the mass 2 is smaller than mass 1

If a freshener is sprayed into a room, the pressure of the gas will remain the same if the temperature remains constant.

Temperature is a measure of the amount of heat energy in a physical system. It is measured in degrees Fahrenheit (°F), Celsius (°C), Kelvin (K), or Rankine (°R). Temperature is a crucial factor in determining the rate of chemical reactions, the viscosity of liquids, and the state of matter, among other things. It is also used to measure the thermal comfort of humans and animals, and is an important factor.

This is because the number of molecules of the freshener in the room will remain constant, and the total pressure of the gas in the room is a result of the number of molecules present. When the temperature remains the same, there is no change in the average kinetic energy of the molecules, so the pressure of the gas will remain unchanged.

The addition of the freshener does, however, affect the composition of the gas in the room. The freshener will add a new type of molecule to the gas, which will change its overall composition. Depending on the type of freshener, the gas may also become more or less reactive and/or flammable.

A ball that bounces rises to a height of 3/4 its original height. The object will bounce 16 times before coming to rest.

The directional speed of an object in motion, as measured by a specific unit of time and observed from a specific point of reference, is what is referred to as velocity. The direction of a body or object's movement is defined by its velocity. In its basic form, speed is a scalar quantity. In essence, velocity is a vector quantity. It is the speed at which distance changes. It is the displacement change rate. Speed is the absence of direction; velocity is the presence of direction. Since velocity is a vector quantity, we must specify both the magnitude (the speed) and the direction of travel when expressing it.

Here,

Given:

Height=13 feet

First bounce=3/4*13=9.75 feet

Second bounce=3/4*9.75=7.3125 feet

Third bounce=3/4*7.3125=5.484 feet

Fifth bounce=3/4*4.11=3.084 feet

Sixth bounce=3/4*3.084=2.31 feet

Answer: Therefore, the force exerted by the elevator floor under that man's feet is 120 Newtons.

Explanation:

A 60 kg man is going to use an elevator that will transport him upwards with an acceleration of 2 m/s². What is the force exerted by the floor of the elevator under the feet of that man?​

Data:

m = 60 kg

a = 2 m/s²

F = ?

The formula for Newton's second law is:

Where

Since we must calculate the force, it is not necessary to solve the formula. We substitute data and solve, then

F = 60 kg × 2 m/s²

F = 120 Newton

Therefore, the force exerted by the elevator floor under that man's feet is 120 Newtons.

The maximum blood volume that can be safely drawn at one time from a 0.77lb guinea pig is 24.5 ml, rounded to 24.5 ml. This calculation was derived by multiplying the average blood volume of 70 ml/kg by the guinea pig's weight of 0.35 kg.  

When drawing blood from a guinea pig, it is important to keep their safety in mind. The volume of blood that should be removed should be no more than 10-15% of the total body weight. This helps to minimize the risk of shock or other complications. Additionally, the guinea pig should be monitored closely during and after the procedure to ensure their safety and comfort level.

Finally, any blood that is drawn should be disposed of properly, as it could contain bacteria or other pathogens.   In conclusion, it is important to be aware of the maximum blood volume that can be safely drawn from a guinea pig. For a 0.77lb guinea pig, this maximum amount is 24.5 ml. Following these guidelines can help to ensure the health and safety of the animal.

All of the statements are True.

The p-wave shadow zone is larger than the s-wave shadow zone because p-waves can travel through the Earth's core, while s-waves cannot. This means that the region where no p-waves are detected (the shadow zone) is larger than the region where no s-waves are detected.

Seismic waves do follow curved paths through the interior of the Earth. This is because the speed of seismic waves depends on the density and elastic properties of the material they are passing through, which vary at different depths and locations.

P-waves travel more slowly in lower density materials. This is because p-waves are compressional waves that are affected by the density of the material they are passing through. Lower density materials will have less resistance to compression, allowing the waves to travel more slowly.

Liquids do not transmit s-waves. This is because s-waves are transverse waves that require a solid medium to propagate. Liquids do not have the same level of shear strength as solids and therefore s-waves cannot pass through them.

where s is the average speed

          d is the total distance covered

          t is the total time taken

The time taken by the car to up a hill is
