The focal length of the lens is 39.3 mm. The result is obtained by using the thin lens equation.

The Thin Lens Equation is the equation used on a thin positive or negative lens.

[tex]\frac{1}{f} = \frac{1}{d_{1} } + \frac{1}{d_{2} }[/tex]

Where

We have a camera with the film 36.9 mm away from the lens and the object distance is 59.2 cm. Determine the focal length!

Let's convert the object distance's unit!

59.2 cm = 592 mm

The distance of the film from the lens is the image distance. So, the focal length is

[tex]\frac{1}{f} = \frac{1}{d_{1} } + \frac{1}{d_{2} }[/tex]

[tex]\frac{1}{f} = \frac{1}{592 } + \frac{1}{36.9 }[/tex]

[tex]\frac{1}{f} = \frac{(592-36.9)}{21844.8 }[/tex]

[tex]\frac{1}{f} = \frac{555.1}{21844.8 }[/tex]

[tex]f = \frac{21844.8}{555.1}[/tex]

29.33 ft/sec is speed  in feet per second.

20 miles= 105600 ft

1 hour= 3600 second

speed= distance/time

speed=105600/3600

speed=29.33 ft/sec

It is possible to express how much an object's location shifts over time or how much it shifts per unit of time using a scalar variable called speed. It is frequently abbreviated to "s." The distance traveled by an object divided by the duration of the period gives the average speed of the object over the period.

The speed-related metric is time divided by distance. While the meter per second (m/s) is the SI unit of speed, the kilometer per hour (kph) is the most widely used unit in daily life (kph).

The flow rate of the faucet is 127.23 cm²/s and diameter below the faucet is 1.88 cm.

For calculating the flow rate, we will use the formula -

Q = Ar

A = πr², were Q is flow rate, A is area and r is radius.

Also, radius = diameter/2

Radius = 1.8/2

Radius = 0.9 cm

Speed = 50 cm/s

Q = πr²v

Q = 3.14×0.9²×50

Q = 127.23 cm²/s

The diameter of stream will be calculated by the formula -

[tex] v_{f}[/tex]² - [tex] v_{i}[/tex]² = 2gy, where [tex] v_{f}[/tex] is final velocity, [tex] v_{f}[/tex] is initial velocity, g is acceleration due to gravity and y is diameter of stream.

[tex] v_{f}[/tex] = ✓50² - 2×9.8×20

[tex] v_{f}[/tex] = ✓2500 - 392

[tex] v_{f}[/tex] = ✓2108

[tex] v_{f}[/tex] = 45.9 cm/s

r = ✓Q/πv

r = ✓127.23/3.14 × 45.9

r = ✓127.23/144.2

r = ✓0.88

r = 0.93 cm

d = 2r

d = 2×0.93

d = 1.88 cm

Thus, flow rate is 127.23 cm²/s and diameter is 1.88 cm.

The total revenue, on the other hand, rises as a result of the higher price and constant quantity demanded for an inelastic good when the price is raised and the demand remains the same.

Inelastic demand is when consumer preferences do not change as much as changes in the price of a good. When the price increases by 20% while the decrease in demand is only 1%, the demand is said to be inelastic. Elastic items are usually required when appropriate substitutes are not available. The items with the most prevalent inelastic demand are utilities, prescription drugs, and tobacco products. Businesses that sell these items may be more tolerant of price changes because demand for them never ceases, regardless of price changes. The amount of a good that is purchased has no effect on price changes when the price elasticity of demand for that good is completely inelastic; rather, higher prices will always lead to higher overall income. whenever the cost of a thing or service changes, the demand for such items remains mostly stable.

Radio waves from the pace are gathered and reflected toward the focal point where the receiver receives them, and waves are transmitted to the recording device the same radio source is being watched by two radio telescopes. On the ground, there is a known separation between the telescopes. As a result, the radio waves from the source will reach each telescope at a little different time. The waves appear slightly differently, with one arriving a little bit later than the other. The difference is a shift in the wave's phase over time.

Due to their phase shift, the two offset waves will not precisely overlap when combined, leading to interference fringes. The angles of their observations shift as the Earth rotates and the telescopes tilt to continue monitoring their source setting.

Similar to how shadows are longer when the Sun is lower, this tracking movement of the telescopes alters the distances that radio light travels from the source to each telescope. This results in various phase delays for the waves as they approach each telescope. The more variables we see, the longer we observe.

The correct answer is Electron Chain Transport.

The process human cells use to generate ATP is called cellular respiration.

In cellular respiration there is a phase of electron transport chain and it produces majority of ATP.

The two ATP-producing processes can be viewed as glycolysis (the anaerobic part) followed by aerobic respiration (the oxygen-requiring part).

Aerobic reaction can be defined as biological and chemical processes that occurs in the presence of oxygen.

Hence, an aerobic reaction requires oxygen before it can take place or occur and it produces adenosine triphosphate (ATP) as one of its end product.

In aerobic respiration, there are two main processes:

It is the electron chain transport, that produces maximum ATPs. This is a stage in cellular respiration.

In mitochondria, between the matrix and inner mitochondrial space, an electron gradient is produced by the function of ETS. This ETS gets electron from NADH and FADH₂. This proton motive force is utilized for ADP and ATP and this production is called oxidative phosphorylation. This is called phosphorylation and along with phosphorylation it also has oxidation. The proton gradient helps in the generation of large amount of ATP molecules through chemiosmosis.

Therefore, this is all about the transfer of energy. This the principle on which microwave works. The transfer of heat energy from one object to the other increases the kinetic energy of the particle of the other object. But no object mean no heat energy transfer and the plate isn't heated.
