The principle that explains why boats can float is called "Archimedes' Principle." This principle states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object. In the case of boats, the shape and design allow them to displace enough water to create a buoyant force that counteracts their weight, enabling them to float.

The name of the principle that explains why boats can float is "Archimedes' principle." This principle states that any object, including boats, will float in a fluid if the weight of the displaced fluid is equal to the weight of the object. This means that when a boat is placed in water, it displaces an amount of water equal to its weight, which creates an upward force called buoyancy that helps it stay afloat.

The maximum kinetic energy of the photoelectrons that could be emitted is 0.80 eV.

To determine the maximum kinetic energy of the photoelectrons emitted, we can use the photoelectric effect equation:
KE_max = h * (c / λ) - W
where KE_max is the maximum kinetic energy of the photoelectrons, h is Planck's constant (6.63 × 10^-34 Js), c is the speed of light (3.00 × 10^8 m/s), λ is the wavelength of the light (458.00 nm), and W is the work function (1.92 eV).
First, convert the wavelength from nm to meters: λ = 458.00 nm × 10^-9 m/nm = 4.58 × 10^-7 m.
Next, calculate the energy of the incident photons: E_photon = h * (c / λ) = 6.63 × 10^-34 Js × (3.00 × 10^8 m/s) / (4.58 × 10^-7 m) = 4.35 × 10^-19 J.
Convert the work function to Joules: W = 1.92 eV × (1.60 × 10^-19 J/eV) = 3.07 × 10^-19 J.
Now, find the maximum kinetic energy: KE_max = 4.35 × 10^-19 J - 3.07 × 10^-19 J = 1.28 × 10^-19 J.
Finally, convert the kinetic energy to eV: KE_max = 1.28 × 10^-19 J × (1 eV / 1.60 × 10^-19 J) = 0.80 eV.

The maximum kinetic energy of the photoelectrons emitted from the metallic plate is 0.79 eV when light with a wavelength of 458.00 nm strikes its surface.

To determine the maximum kinetic energy of photoelectrons emitted from a metallic plate, we can use the equation:

E = hf - Φ

where E is the maximum kinetic energy of the photoelectrons, h is Planck's constant (\(6.626 \times 10^{-34\) J∙s), f is the frequency of the incident light, and Φ is the work function of the metal.

First, we need to calculate the frequency of the light using the equation:

c = λf

where c is the speed of light (\(3.0 \times 10^8\) m/s) and λ is the wavelength of the incident light. Rearranging the equation, we find:

f = c / λ

Plugging in the values, we have:

f = (\(3.0 \times 10^8\) m/s) / (\(458.00 \times 10^{-9\) m) = \(6.55 \times 10^{14\) Hz

Now, we can calculate the energy of a single photon using the equation:

E_photon = hf

Plugging in the value of f, we get:

\(E_{\text{photon}} = (6.626 \times 10^{-34} \ \text{J} \cdot \text{s}) \times (6.55 \times 10^{14} \ \text{Hz}) = 4.34 \times 10^{-19} \ \text{J}\)

To convert this energy to electron volts (eV), we divide by the electron charge (\(1.6 \times 10^{-19}\), giving:

\(E_{\text{photon}} = \frac{4.34 \times 10^{-19} \ \text{J}}{1.6 \times 10^{-19} \ \text{C}} = 2.71 \ \text{eV}\)

Finally, we can determine the maximum kinetic energy of the photoelectrons using the equation mentioned earlier:

E = E_photon - Φ

Plugging in the values, we have:

E = (2.71 eV) - (1.92 eV) = 0.79 eV

Answer:

what exactly are the following?

To calculate the amount of potential energy initially stored in the spring, we need to consider the conservation of mechanical energy.

The mechanical energy of the block-spring system is conserved when no external forces other than gravity and friction are acting on it. At point A, the mechanical energy is stored entirely as potential energy in the compressed spring. The potential energy stored in the spring can be calculated using the formula: Potential Energy (PE) = (1/2)kx^2

where k is the spring constant and x is the displacement of the spring from its equilibrium position.

To find the spring constant, we need to know the force constant of the spring (k) or the spring's compression distance (x). Unfortunately, this information is not provided in the given question. If you have any additional information about the spring constant or the compression distance, please provide it so that I can assist you further.

In series combination less rate of joule hating should be observed as compared to when connected in parallel combination .

Joule heating, also known as resistive, resistance, or Ohmic heating, is the process by which the passage of an electric current through a conductor produces heat.

Joule's first law states that the power of heating generated by an electrical conductor equals the product of its resistance and the square of the current:

When two or more resistors are connected end to end consecutively, they are said to be connected in series combination. The combined resistance of any number of resistances connected in series is equal to the sum of the individual resistances.

When two or more resistances are connected between the same two points, they are said to be connected in parallel combination. The reciprocal of the combined resistance of a number of resistances connected in parallel is equal to the sum of the reciprocals of all the individual resistances.

Rate of joule heating can be calculated by the formula

Power = \(V^{2}\) / R

V = voltage

R = resistance

When both are connected in series than their equivalent resistance will be more as compared to when they are connected in parallel.

Power is inversely related to resistance , if voltage is constant

Answer:

202.8m

Explanation:

Given that A pirate fires his cannon parallel to the water but 3.5 m above the water. The cannonball leaves the cannon with a velocity of 120 m/s. He misses his target and the cannonball splashes into the briny deep.

First calculate the total time travelled by using the second equation of motion

h = Ut + 1/2gt^2

Let assume that u = 0

And h = 3.5

Substitute all the parameters into the formula

3.5 = 1/2 × 9.8 × t^2

3.5 = 4.9t^2

t^2 = 3.5/4.9

t^2 = 0.7

t = 0.845s

To know how far the cannonball travel, let's use the equation

S = UT + 1/2at^2

But acceleration a = 0

T = 2t

T = 1.69s

S = 120 × 1.69

S = 202.834 m

Therefore, the distance travelled by the cannon ball is approximately 202.8m.

The clown should look 1 m from the floor to see his feet in the full-length mirror.

The height of the clown is 2 m, and the mirror is a full-length mirror, which means it covers the entire height of the clown from the floor to the ceiling. Therefore, the clown's reflection in the mirror will also be 2 m tall.  

To see his feet in the mirror, the clown needs to look at the same distance from the floor as the distance between his feet and the floor. Since the clown's height is 2 m and his feet are at the bottom, 1 m away from the floor, he needs to look at a distance of 1 m from the floor to see his feet in the mirror. Therefore, the correct answer is "O 1 m from the floor."

A:  Screws are a simple machine that make doing work easier.

Work = W = Fd

F = W/d

So by increasing distance (d), you decrease the amount Force needed to do the work.

By applying a small rotational force (circular direction) on the screw, the axial force is amplified.  It takes less force to turn a screw around than to drive a nail straight into the wall.

B:  To make the job even easier, choose a screw with a "finer" thread.  The smaller the pitch (the distance between the screw's threads), the greater the mechanical advantage (the ratio of output to input force).  

Part A: The screw makes the student's work easier by providing a force that is directed downwards into the wall, allowing the student to secure the picture frame in place with a relatively small distance of travel.

Force is a physical quantity that is defined as the product of mass and acceleration. It is a vector quantity, meaning it has both magnitude and direction. Force is one of the fundamental concepts of physics and is responsible for the motion of objects. It is also responsible for the interaction between objects, such as the force of gravity that keeps the planets in orbit around the sun. Force can be applied to objects in order to cause them to move, accelerate, decelerate, or change direction. Force can also be used to do work, such as lifting a weight or pushing a car. Force is an important concept in physics and is used to explain many phenomena in the natural world.

Part B: A change to the screw design that would make the student's work even easier would be to use a self-tapping screw, which has a sharp point that allows it to cut its own thread into the wall, eliminating the need to pre-drill a hole.
