A car accelerated to 10m/2 after being rear-ended by a truck. The car and it occupant have a ma of 1300kg. How much force did the truck place on the Uber car?

Answer:

18.75 °C

Explanation:

Q = mcΔT

ΔT = Q / (mc)

convert g → kg

200 g = 0.20 kg

ΔT = (1500 J) / (0.20 kg)(400 J/kg·°C) = 18.75 °C

Taking into account the definition of calorimetry,  the increase in temperature is 18.75°C.

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

In this way, between heat and temperature there is a direct proportional relationship, where the constant of proportionality depends on the substance that constitutes the body and its mass.

The equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where:

In this case:

Replacing in the definition of calorimetry:

1500 J= 400  J/(kg °C)× 0.200 g× ΔT

Solving:

1500 J÷ [400  J/(kg °C)× 0.200 g]= ΔT

18.75 °C= ΔT

In summary, the temperature variation is 18.75°C.

One way organisms with similar niches reduce competition when they are found in the same ecosystem is by resource partitioning.

One example of resource partitioning is when two species of birds foraging together feed on different resources; one eats insects on tree trunks while the other eats insects in the outer branches.

Resource partitioning, which helps prevent rivalry in an ecological niche, is the division of scarce resources among species.

Two similar species employ mostly non-overlapping resources as a result of this type of evolution, and as a result, they occupy different niches. Because there is less direct rivalry between the species as a result of this resource partitioning, the species can coexist.

The total travelled distance is • Speed, time and distance is one of the most common and important topics in the Mathematics or Quant section.

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

For instance, 50 km/hr west denotes the velocity of a car whereas 50 km/hr (31 mph) denotes the speed at which it is moving down a route.

The average speed of an object is determined by dividing the distance traveled by the amount of time it takes the object to reach the distance.

When two different molecules travel in opposite directions through the same carrier or transport protein—one into the cell and the other out of the cell—the protein is said to be an antiport.

Proteins called symports allow two molecules to go across membranes in the same direction (also called symporters, synports, or symporters). The movement of two molecules across the bilayer in opposite directions is accomplished by an antiport protein. Ions can move more easily when proteins called ionophores are present. To move molecules like glucose, transport proteins employ a passive strategy. Transport proteins, however, actively allow sodium and potassium ions to cross the neuronal membrane in spite of the concentration gradient.

The force exerted on the woman by the seat belt is equal to 50 kg x 20 m/s2 = 1000 N.

Force is a push or pull that acts upon an object, causing it to accelerate or change direction. It is an influence that can cause an object to change its motion, direction, shape, or even energy. Force can be generated through direct physical contact, or it can be generated from a distance, such as when a magnet pulls on a piece of metal. Forces are measured in newtons, and the SI unit for force is the Newton (N).

The force exerted on the woman by the seat belt is equal to her mass times the acceleration experienced by the car. The acceleration of the car is equal to the change in velocity (10 m/s) divided by the time it took for the car to stop (0.50 s), which is equal to 20 m/s2. Therefore, the force exerted on the woman by the seat belt is equal to 50 kg x 20 m/s2 = 1000 N.

No, mass and acceleration are two different physical quantities that do not have any direct relationship.

Mass is a scalar quantity that measures the amount of matter in an object, and it is independent of its location or motion. It is the total amount of matter in an object, and it doesn't change when the object is accelerated or decelerated.

Acceleration, on the other hand, is a measure of how much the velocity of an object is changing over time. It can be defined as the rate of change of velocity. The acceleration of an object can change if the object is accelerating or decelerating, but it doesn't change the mass of the object.

So, mass does not depend on acceleration and acceleration does not depend on mass. They are independent physical quantities that are used to describe different aspects of an object. For example, the mass of an object determines its inertia, while acceleration determines how fast an object is changing its velocity.

The load of the pickup truck spills due to an unbalanced force acting on it caused by the collision from the car.

Newton's first law states that an object at rest will remain at rest unless acted upon by an unbalanced force. In this scenario, the load of the pickup truck is at rest in the back of the truck, but when the car rear-ends the pickup truck, it applies an unbalanced force on the load, causing it to spill out of the truck.

Newton's second law states that the force applied on an object is equal to the mass of the object multiplied by its acceleration. In this scenario, the car applies a force on the load of the pickup truck, which is equal to the mass of the load multiplied by the acceleration of the car at the time of the collision. The force causes the load to spill out of the truck.

Newton's third law states that for every action, there is an equal and opposite reaction. In this scenario, when the car rear-ends the pickup truck, the car experiences an equal and opposite force, which is the reaction to the force it applies to the load of the pickup truck.

In summary, the load of the pickup truck spills due to an unbalanced force acting on it caused by the collision from the car. The force applied on the load of the pickup truck is equal to the mass of the load multiplied by the acceleration of the car at the time of the collision.

Torque is maximum in an induction motor when rotor resistance is equal to the rotor reactance.

Let us mathematically represent the equation of Torque of a three-phase induction motor:

where Ns: Synchronous speed

V: Voltage of supply

R2: Rotor resistance

X2: Rotor reactance

From above formula, it can be concluded that induction motor torque varies with Slip and rotor resistance.

To get maximum torque, we apply the condition:

sm = Rm/Xm = 1

Therefore, Rm = Xm

where Rm: Motor Resistance/Phase

Xm: Motor Reactance/Phase

To calculate T1 and T2, we need to know the force acting on the object and the angle at which it is acting. From the information given, we know that a 100 N force is acting at an angle of 30 degrees above the horizontal.

First, we can use trigonometry to calculate T1, the force acting in the vertical (upwards) direction. We can use the sine function to calculate T1, as sine represents the ratio of the opposite side to the hypotenuse of a right triangle.

T1 = F * sin(theta)

T1 = 100 N * sin(30)

T1 = 50 N

Then we can use the cosine function to calculate T2, the force acting in the horizontal (horizontal) direction.

T2 = F * cos(theta)

T2 = 100 N * cos(30)

T2 = 86.6 N

So T1 = 50 N and T2 = 86.6 N are the force T1 and T2 acting on the object at an angle of 30 degrees above the horizontal.

It is important to note that T1 and T2 are the components of the force F, and the sum of T1 and T2 is the magnitude of the force F.

Because velocity is a vector and mass is a scalar quantity, momentum is a vector quantity. Momentum is defined as mass multiplied by velocity. The definition of momentum is "mass moving."

In order to calculate the force required to lift an object weighing 220 newtons to a height of 4 meters with a lever having an effort arm of 10 meters and a load arm of 2 meters, we must first determine the amount of work done.

Since 400 joules of work was done, we can use the formula Work = Force x Distance to calculate the force required.

In this case, the distance is 4 meters, so the equation becomes

400 = Force x 4.

By dividing 400 by 4 we can determine that the force required is 100 newtons.
