a) To find the speed of the signal in water, we can use the equation:

Speed = Wavelength x Frequency

Where Wavelength is given as 1.5 mm and Frequency is given as 1 x 10^6 Hz.

Speed = 1.5 x 10^-3 m x 10^6 Hz = 1.5 x 10^3 m/s

So the speed of the signal in water is 1.5 x 10^3 m/s

b) To find the period in water, we can use the equation:

Period = 1 / Frequency

Where Frequency is given as 1 x 10^6 Hz

Period = 1 / (1 x 10^6) s = 1 x 10^-6 s = 1 microsecond

So the period of the signal in water is 1 microsecond

c) The speed of sound in air is approximately 343 m/s. Since the frequency of the signal remains constant and the speed of sound in air is different than the speed of sound in water, the wavelength of the signal will also be different. However, since the period is inversely proportional to the frequency and is independent of the medium, the period of the signal in air will be the same as in water, which is 1 microsecond.

It is the property of a rotating body determined by the product of the rotating object's moment of inertia and angular velocity. It is a vector quantity, which means that the direction is taken into account in addition to the magnitude. It is expressed in SI base units: Kg.m2.s-1

Angular momentum is the rotational equivalent of linear momentum in physics. It is an important physical quantity because it is a conserved quantity—in a closed system, the total angular momentum remains constant. Both the direction and magnitude of angular momentum are conserved. The property of any rotating object given by moment of inertia times angular velocity is defined as angular momentum. It is the property of a rotating body determined by the product of the rotating object's moment of inertia and angular velocity. An object's angular momentum is the product of its rotational inertia and angular velocity. The angular velocity of an object is the rate at which it turns.

A automobile with a mass of 1000 kg and a speed of 30 m/s has kinetic energy equal 450,000 J.

If an object's mass increases, so will its kinetic energy. The object's speed is given by v. The aforementioned connection demonstrates that an object's kinetic energy is directly proportional to the sum of its mass and velocity.

Possible explanation: Because kinetic energy and speed are closely correlated, an object's kinetic energy increases as its speed increases. The nonlinear (square) proportional relationship (KE v2) between kinetic energy and speed 1. As an object's speed doubles, its kinetic energy grows four times. 2. As the object's speed is halved, the kinetic energy falls by a factor of four.

The light source and aperture are most important in determining the resolution of the microscope, as the resolution of the microscope is determined by the cone of light entering the lens, the refractive index, and the wavelength of the light.

The most important factor in determining the resolution of a microscope is the numerical aperture (NA) of the objective lens. The higher the NA, the higher the resolution. However, other factors also play a role. The numerical aperture of the condenser that forms the beam of light that illuminates the object on the slide should match the numerical aperture of the objective lens (or at least not be much smaller). Another factor is the refractive index of the medium between the objective lens and the slide. For low magnification lenses (low NA) this medium is usually air. Air has a refractive index of 1.0 (for the wavelengths of light used in microscopy).

The distance the springs need to bring the car to a stop can be calculated using the equation for the potential energy of an object at a height, which is:

PE = mgh

where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s^2), and h is the height.

In this case, the car has a mass of 1,836 kg and is at a height of 88.6 meters. So the potential energy of the car at the top of the roller coaster is:

PE = 1,836 kg * 9.8 m/s^2 * 88.6 m = 1.5*10^5 J

Next, we need to find the work done by the spring. Work can be calculated using the equation

W = 1/2 * kx^2

where k is the spring constant (100,000 N/m) and x is the compression distance of the spring.

Since the work done by the spring is equal to the potential energy of the car, we can set the two equations equal to each other and solve for x (the compression distance of the spring):

1/2 * kx^2 = 1.510^5 J

x = sqrt(2 * 1.510^5 J / 100,000 N/m)

x = sqrt(30000/100000)

x = 0.173 m

Therefore, the spring needs a distance of 0.173 m to bring the car to a stop.

Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an external force.

In simple terms, it says that an object will remain in its current state of motion unless acted upon by a net force.

This means that if an object is moving in a straight line at a constant speed, it will continue to move in that way unless something changes its motion.

Similarly, if an object is at rest, it will stay at rest unless something applies a force to it. This law is fundamental in understanding the principles of motion and forms the basis for many other laws of physics.

The full-load current of a 25-horsepower, 480-volt, 3-phase, squirrel-cage induction motor is 12.7 A.

To calculate the full-load current of a 25 horsepower, 480-volt, 3-phase, squirrel-cage induction motor, you can use the formula:

Full-load current (I) = (Horsepower * 746) / (Voltage * 1.73 * Power factor)

where 1.73 is the square root of 3, which accounts for the 3-phase power and Power Factor is assumed to be 0.8

Plugging in the given values, we get:

I = (25 * 746) / (480 * 1.73 * 0.8)

I = 25746/(4801.73*0.8)

I = 25746/(4803.07)

I = 25*746/1478.4

I = 25*0.508

I = 12.7 A

Therefore, the full-load current of a 25-horsepower, 480-volt, 3-phase, squirrel-cage induction motor is 12.7 A.

The kinetic energy for an 10 kg object at a 5 m/s speed is 125.

Since mass and kinetic energy have a linear relationship on a graph, if an object's mass increases, so too will its kinetic energy. The object's speed is v. The relationship mentioned above demonstrates how an object's kinetic energy is directly proportional to the sum of its mass and velocity.

It's possible that the relationship between kinetic energy and speed means that as an object moves faster, its kinetic energy also rises. Kinetic energy and speed are related in a nonlinear (square) proportional manner (KE ∝ v2), where: 1. As an object's speed doubles, its kinetic energy grows fourfold. 2. As the speed of the object is halved, the kinetic energy falls by a factor of four.
