allison has to design a device that converts energy between two different forms. she decides she wants to convert electrical energy into motion and sound. which invention should she model her design after?

Answers

Answer 1

The motor is an excellent invention for Allison to use as a model for her device.

People use both interchangeably, but the difference is that motors run on electricity and engines run on combustion. The engine converts various forms of fuels into mechanical force, while the motor transforms electrical energy into mechanical energy.

They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field. This force creates a torque on a loop of wire present in the magnetic field, which causes the motor to spin and perform useful work.

q2: if a system contains 2 objects, is there a possibility that the momentum of one object is not conserved?

Answers

Yes, there a possibility that the momentum of one object is not conserved.

In a two-body collision, is momentum always conserved?

Newton's third law suggests that momentum is always conserved in collisions between two isolated objects. In collisions, it is believed that the interaction between the colliding items lasts for a brief period of time, making the impulse caused by outside forces insignificant.

For the momentum to be conserved, a system must satisfy two conditions:

Throughout the interaction, the system's mass must remain constant.

The system must be subject to zero net external force.

Momentum does not always change and is not conserved because the collision is automatically conserved when the kinetic energy is. The amount of momentum needed when there is a change in speed during a collision remains constant.

Explain what an acceleration is.

Acceleration is the rate of change in both speed and direction of velocity over time. Anything is said to have been accelerated when it goes faster or slower in a straight line.

Solution:

friction force on the upper block = umg

so writing the equation of motion for the upper block

T - f = ma

or T-2.5506 = 2a

writing the equation of motion for the lower block

mg-T=ma

Two identical objects are moving directly toward one another at the same speed v. What is the total kinetic energy of the system of the two objects?

Answers

The total kinetic energy of the system of the two objects can be achieved by adding of the kinetic energies of first and second body.

How do you find the kinetic energy of two objects?

Kinetic energy is directly proportional to the mass of the thing 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. So the formula for kinetic energy is that it's equal to 1/2 times the mass of the object, times the immensity of its velocity squared, or another way to think about it, its speed squared. In an elastic collision, both the impulse and the kinetic energy of the system are maintained. On the other hand, in an inelastic collision, momentum is sustained but kinetic energy can not be sustained.

So we can conclude that two objects of equal mass moving with equal speeds in opposite directions have a total momentum of zero, but their total kinetic energy is not zero.

What is frictional force?

Frictional force is defined as the force that opposes motion when one body's surface comes into contact with the surface of another. Friction force reduces a machine's mechanical advantage, or the ratio of output to input. An automobile uses about one-quarter of its energy to restrict friction force, but friction in the tyres keeps the car on the road, and friction in the clutch allows us to drive.

Friction is one of the most prevalent phenomena in the physical universe, affecting everything from matchsticks to machines to the molecular structures of every simple and complex object.

Frictional force is the opposing force formed when two surfaces attempt to move in the same direction or in opposite directions. A frictional force's primary function is to generate resistance to the mobility of one surface over another. The frictional force is determined by the texture of the body's surface.

The T.A.R.D.I.S. travels 5026.6 m while slowing down.

What is speed?

Speed is distance travelled by the object per unit time. Due to having no direction and only having magnitude, speed is a scalar quantity With SI unit meter/second

Initial speed of the Doctor; u = 406.36 m/s .

Final speed of the Doctor; v = 1035.99 m/s.

Time taken =  6.97 s.

So, average speed = ( initial speed + final speed)/2

specular reflection obeys the laws of reflection while diffuse reflection does not. question 18 options: true false

Answers

False, In contrast to diffuse reflection, specular reflection violates the laws of reflection. Normal reflections are parallel to the surface of a flat mirror. The law of reflection only applies to flat surfaces. Convex mirrors serve as passenger door mirrors in cars.

The law of reflection states that the angle of incidence & angle of reflection is identical. A smooth finish causes a specular reflection of light. Since incident rays are parallel, reflected rays must also be parallel. Light striking a rough surface causes diffuse reflection.

The two principles governing specular reflection are,

1. At the point of incidence, the incidence angle, the reflected ray, as well as the normal towards the reflecting interface all lie in the very same plane.

2. The angle of incidence and reflection are equal.
