A combination of longitudinal and transverse waves is called a "surface wave."

Surface waves are a type of wave that travel along the boundary or surface between two different materials or mediums, such as between air and water or between two layers of rock. These waves are characterized by a complex motion that combines both longitudinal and transverse components, resulting in a wave that moves both up and down and side to side.

Surface waves are often the most destructive type of wave in seismic activity, such as earthquakes, as they can cause the ground to move in a circular or elliptical motion. They are also important in the study of fluid dynamics, such as ocean waves and the behavior of fluids in pipes and channels.

Examples of surface waves include Rayleigh waves and Love waves, which are named after the scientists who first studied them. Rayleigh waves are primarily responsible for the shaking that occurs during earthquakes, while Love waves are responsible for the horizontal movement of the ground.

c. The glass will fall out of the bucket if the normal force between the glass and bucket equals zero. The speed with which she spin the bucket to prevent this from happening is 3.83 m/s.

d. The string will break if the tension on it is more than 100 N. The range of speeds can prevent the string from breaking is 3.83< Vtop<4.99 m/s

When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.

Given, Angela has a bucket of mass 2 kg tied to a string. She places a drinking glass of mass 0.5 kg in the bucket. She spins the bucket in a vertical circle of radius 1.5 m. She must swing the bucket to keep the glass from falling out.

a. The free body diagram of the bucket and glass is attached below.

b. Bucket will undergo centrifugal force

Fb = mVtop² /R

From the equilibrium of forces, we have

For bucket,

T +mb xg - N = mb x Vtop² /R..............(1)

For glass,

mg x g + N = mg x Vtop² /R..............(2)

Thus, this is the net force equation on the glass.

c. On adding both the equations. we have

T + (mb + mg) xg = (mb + mg) Vtop² /R

Substituting the values, T = 0 and from the question, we get

0 + (2+0.5) 9.81 = (2+0.5)(Vtop²/0.5)

Vtop = 3.83 m/s

Thus, the speed of spin to prevent glass from falling out is 3.83 m/s

d. The string will break if the tension on it is more than 100 N

100 + (2+0.5) 9.81 = (2+0.5)(Vtop²/0.5)

Vtop = 4.99 m/s

Thus, the range of velocity is 3.83< Vtop<4.99 m/s

The change in the electrical energy of a proton would be 2.40 x 10^-16 J.

The change in electrical potential energy of a charged particle in a uniform electric field is given by the equation:

ΔPE = qEd

where q is the charge of the particle, E is the magnitude of the electric field, and d is the distance moved by the particle in the direction of the electric field.

In this case, the proton has a charge of q = 1.60 x 10^-19 C and moves a distance of d = 5 m - 2 m = 3 m in the direction of the electric field. The magnitude of the electric field is E = 5.0 x 10^2 N/C.

Substituting these values into the equation, we get:

ΔPE = (1.60 x 10^-19 C)(5.0 x 10^2 N/C)(3 m)

ΔPE = 2.40 x 10^-16 J

Therefore, the change in electrical energy of the proton as it moves from x = 5 m to x = 2 m is 2.40 x 10^-16 J.

The phase at which tidal variation would be the least during the entire day is called the "neap tide." Neap tides occur during the first quarter and third quarter moon phases. During these phases, the gravitational forces of the moon and the sun are at right angles to each other, resulting in the least tidal variation.

Seven days after a spring tide, the sun and moon are at right angles to each other. When this happens, the bulge of the ocean caused by the sun partially cancels out the bulge of the ocean caused by the moon. This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average. Neap tides occur during the first and third quarter moon, when the moon appears "half full."

So, the phase at which tidal variation would be the least during the entire day is called the "neap tide."

8.25749 x 10¹⁷ protons and 5.26 x 10¹⁴ electrons; the charge on this object is 0.4791  coulombs

To determine the charge on an object given the number of protons and electrons, we need to consider the elementary charge of a single proton and electron and their respective quantities.

The elementary charge, denoted as "e," is the fundamental unit of electric charge and is approximately equal to 1.602 x 10⁻¹⁹ coulombs.

Given that the number of protons is 8.25749 x 10¹⁷ and the number of electrons is 5.26 x 10¹⁴, we can calculate the total charge on the object.

Charge on protons = (Number of protons) * (Charge of a proton)

= (8.25749 x 10¹⁷) * (1.602 x 10⁻¹⁹ C)

Charge on electrons = (Number of electrons) * (Charge of an electron)

= (5.26 x 10¹⁴) * (-1.602 x 10⁻¹⁹ C) (Note: electrons have a negative charge)

Total charge = Charge on protons + Charge on electrons

Performing the calculations, we have:

Charge on protons = (8.25749 x 10¹⁷) * (1.602 x 10⁻¹⁹ C) ≈ 1.3227 C

Charge on electrons = (5.26 x 10¹⁴) * (-1.602 x 10⁻¹⁹ C) ≈ -0.8436 C

Total charge = 1.3227 C + (-0.8436 C) ≈ 0.4791 C

Therefore, the charge on this object is approximately 0.4791 coulombs.

The intensity of a sound wave is directly proportional to the square of its amplitude. This means that if the amplitude of a sound wave is quadrupled (increased by a factor of 4), the intensity of the wave will increase by a factor of 16 (4 squared).

This increase in intensity can be perceived as a much louder sound, as the energy carried by the wave has increased significantly.

It is important to note that while the amplitude and intensity of a sound wave are related, they are not the same thing.

Amplitude refers to the magnitude of the displacement of the wave from its equilibrium position, while intensity refers to the amount of energy that is transmitted through the wave per unit area per unit time.

The elastic potential energy of an elastic material (e.g a spring, a wire), is the energy stored when the material is stretched or compressed. It is given by

U = \(\frac{1}{2}kx^2\)               --------------------(i)

Where;

U = potential energy stored

k = spring constant of the material

x = elongation (extension or compression of the material).

From the first statement;

when elongation (x) is 4cm, energy stored (U) is E

Substitute these values into equation (i) as follows;

E = \(\frac{1}{2}k(4)^2\)

E = 8k

Make k subject of the formula    

k = \(\frac{E}{8}\)   [measured in J/cm]

From the second statement;

It is stretched by 4cm.

This means that total elongation will be 4cm + 4cm = 8cm.

The potential energy stored will be found by substituting the value of x = 8cm and k = \(\frac{E}{8}\) into equation (i) as follows;

U = \(\frac{1}{2}\frac{E}{8} (8)^2\)  

U = \(\frac{1}{2}{8E}\)

U = \({4E}\)

Therefore, the potential energy stored will now be 4 times the original one.

Rectilinear motion is a type of motion in which an object moves along a straight line. An example of rectilinear motion is the hot water that falls into a coffee cup from a coffee vending machine.

Suppose that the coffee vending machine drops hot water into a cup at a constant rate of 5 mL/s. If the cup is initially empty and can hold up to 250 mL of hot water, how long will it take for the cup to be filled?
To solve this problem, we can use the equation: distance = speed x time. In this case, the distance is the volume of water that falls into the cup, the speed is the constant rate of 5 mL/s, and the time is what we are trying to find. So, we can set up the equation:
250 mL = 5 mL/s x time
Simplifying, we get:
time = 250 mL / 5 mL/s = 50 s

Therefore, it will take 50 seconds for the coffee cup to be filled with hot water. This is an example of rectilinear motion because the hot water falls straight down into the cup, without any changes in direction.

Given that,

A basketball is dropped from top of the rim.

It takes 1.3s to fall.

We need to find the displacement of the basketball. Let the displacement is d. Using second equation of kinematics,

\(d=ut+\dfrac{1}{2}at^2\)

Where

u is the initial velocity, u = 0

\(d=\dfrac{1}{2}\times 10\times 1.3^2\\\\d=8.45\ m\)

So, the displacement of the basketball is 8.45 m.

The intensity of a linearly polarized electromagnetic wave is directly proportional to the square of its electric field amplitude.

The electric field of a linearly polarized electromagnetic wave can be represented by a sine or cosine function, where the amplitude of the wave represents the maximum value of the electric field.

The intensity of the wave is proportional to the average power per unit area that is carried by the wave.

Mathematically, the intensity (I) of an electromagnetic wave is given by the formula:

I = (1/2)εcE0^2

where ε is the electric constant (approximately equal to 8.85 x 10^-12 F/m), c is the speed of light in a vacuum (approximately equal to 3.00 x 10^8 m/s), and E0 is the amplitude of the electric field.

From this formula, it is clear that the intensity of the wave is proportional to the square of the electric field amplitude.

Therefore, if the electric field amplitude of a linearly polarized electromagnetic wave is increased by a factor of 2, the intensity of the wave will increase by a factor of 4 (i.e., 2 squared).

Similarly, if the electric field amplitude is decreased by a factor of 2, the intensity of the wave will decrease by a factor of 4.
