The main advantage multistage rockets have over conventional rockets is they get lighter by dropping empty sections that held fuel. So, option D is the correct answer.

Multistage rockets have an advantage over conventional rockets since they are outlined to drop off empty segments that held fuel as the rocket gains height. This diminishes the weight of the rocket, making it less demanding to realize elude speed and reach the circle. As each organizes is utilized, it is discarded, diminishing the general weight of the rocket and making it more effective.

Multistage rockets are more flexible and can be utilized for a more extensive extend of missions. They can be custom fitted to meet the particular necessities of a mission by including or evacuating stages, which permits them to carry payloads to diverse heights and speeds. In differentiation, conventional rockets carry all of their fuel and engines with them through the complete mission, making them heavier and less proficient.

48 m/s in terms of km/h is 720.8 km/h. In terms of m/min is 2880 m/min, in terms of km/s is 0.048 km/s and in terms of km/min is 2.88 km/min.

To solve this question, we need to understand some terms. The unit of velocity is measured in m/s. It can be expressed in different units of velocity.

1 km (kilometer) = 1000 meter

1 h (hour) = 3600 seconds

1 minutes = 60 seconds

To convert m/s into km/h,

48 m/s * 3600/1000 =  172.8 km/h

To convert m/s into m/min,

48 m/s * 60 = 2880 m/min

To convert m/s into km/s,

48 m/s ÷ 1000 = 0.048 km/s

To convert m/s into km/minutes,

48 m/s * 60 / 1000 = 2.88 km/min

Therefore, the 48 m/s expressed is 172.8 km/h, 2880 m/min, 0.048 km/s and 2.88 km/min.

48 m/s is equivalent to  172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

To express 48 m/s in different units of velocity:

km/h (kilometers per hour):

To convert m/s to km/h, we can use the conversion factor of 3.6 since 1 m/s is equal to 3.6 km/h.

48 m/s * (3.6 km/h / 1 m/s) = 172.8 km/h

Therefore, 48 m/s is equivalent to 172.8 km/h.

m/min (meters per minute):

To convert m/s to m/min, we can use the conversion factor of 60 since there are 60 seconds in a minute.

48 m/s * (60 m/min / 1 s) = 2880 m/min

Therefore, 48 m/s is equivalent to 2880 m/min.

km/s (kilometers per second):

Since 1 kilometer is equal to 1000 meters, to convert m/s to km/s, we divide the value by 1000.

48 m/s / 1000 = 0.048 km/s

Therefore, 48 m/s is equivalent to 0.048 km/s.

km/minute (kilometers per minute):

To convert m/s to km/minute, we first need to convert m/s to km/s (as calculated in the previous step) and then multiply by 60 to convert seconds to minutes.

0.048 km/s * 60 = 2.88 km/minute

So, 48 m/s is equivalent to 2.88 km/minute.

Hence, 48 m/s is equivalent to approximately 172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

Answer:

It cannot reach us by conduction or convection as there is no medium such as air in most part of the space between the earth and the sun. From the sun the heat comes to us by another process known as radiation. The transfer of heat by radiation does not require any medium.

Answer:

Heat can't be transferred from sun to earth by conduction, because air is a bad conductor of heat. Convection is the transfer of heat in gases & liquids. Convection occurs when a heated fluid moves away from the source of heat and comes in contact with other substances, transferring some of their energy.

The maximum energy of photoelectrons emitted from a metal surface depends on the frequency of the incident light and the work function of the metal.

Therefore, the correct answer is option d: II and III only. The energy of photoelectrons is determined by the photoelectric effect, which states that electrons can be ejected from a metal surface when it absorbs light with a certain frequency or higher. The work function is the minimum energy required to remove an electron from the metal, and it varies for different metals. The frequency of the incident light must be equal to or greater than the threshold frequency for the photoelectric effect to occur. However, the intensity of the incident light does not directly affect the maximum energy of the photoelectrons, but it influences the number of photoelectrons emitted. In summary, the maximum energy of emitted photoelectrons depends on the frequency of the incident light and the work function of the metal.

Radiation frequency and intensity are directly inversely related. The quantity of photo-electrons released by the metal also increases as radiation frequency rises with increasing radiation intensity. When the radiation's wavelengths are all raised by the same amount, The relationship between frequency and wavelength is inverse. As a result, the frequency drops. The quantity of photo-electrons released by the metal reduces as frequency lowers. The gain of kinetic energy reduces as the work function of the metal increases. The quantity of photo-electrons released by the metal reduces as energy lowers.

1. DECOY PRICING

This occurs when customers make a purchase they must often choose between products with different prices and attributes.

This method of pricing is meant to influence the consumer's purchasing decision and maximise the sales of one particular product. The seller will offer at least three products; two of the products will have a similar or equal price. The two products with the similar prices should be the most expensive ones, and one of the two should be less attractive than the other.

2. LOSS LEADER

This is when a product is sold at a low price (often without profit) in order to stimulate other profitable sales or to attract new customers.

The main is that it will help the business to expand their market share as a whole. It's common practice when first entering a market as it introduces new customers to a service or product in the hope of building a customer base and securing future

3.ODD PRICING

This is a method of psychological pricing a product. Prices ending in 9, 95, 97, 99 are sometimes called “charm prices” and in this type of pricing, the seller fixes a price where the last digits are odd numbers. This is intended to give the buyer no room for manœuvering or for bargaining as the price appears to be less - a product priced at £9.99 will seems much cheaper than one priced at £10.00

4. PRICE DISCRIMINATION

The purpose of price discrimination is to capture the market's consumer surplus and generate the most revenue possible for a product. Identical goods or services are sold at different prices from the same provider to different segments of the market. Industries that commonly use price discrimination include the travel industry, pharmaceuticals and textbook publishers.

5. PRODUCT BUNDLE PRICING

Using this method, sellers will combine several products in the same package. It also serves to move old stock. Blu-ray and videogames are often sold using the bundle approach once they reach the end of their product life cycle. This technique is used at auctions where one attractive item may be included in a lot with a box of less interesting things. Buyers must bid for the entire lot. It’s a good way of moving slow selling products, and in a way is another form of promotional pricing.

Uranus is distinguished from all other planets because it has an extreme tilt of almost 98 degrees on its axis.

This means that the planet essentially orbits on its side and experiences extreme seasonal variations that are not present on any other planet in the solar system.

Uranus is the seventh planet from the Sun and is classified as an ice giant, meaning that it is primarily composed of water, ammonia, and methane ice rather than rock and metal like the terrestrial planets.

Its atmosphere is mostly composed of hydrogen and helium, with traces of methane that give the planet its distinctive blue-green color.

The factor that distinguishes Uranus from all other planets is its extreme axial tilt.

While most planets in the solar system have an axial tilt that is roughly in line with the plane of their orbit, Uranus is tilted at almost 98 degrees.

This means that the planet essentially orbits on its side, and its north and south poles are located where the equator would be on other planets.

As a result, Uranus experiences extreme seasonal variations as different parts of the planet are exposed to the Sun's rays over the course of its 84-year orbit.

Answer: B

Explanation: it is perpendicular to a surface

Answer:

it is perpendicular to a surface

Explanation:

Answer:

The total distance between A and B is 30 km

Explanation:

The given information are;

The time duration of the acceleration of the train from station A = 3 minutes = 0.05 hours

The speed attained by the train after the acceleration = 144 km/h

The time duration the train maintains the speed = 10 minutes = 0.1\(\bar 6\) hours

The time duration in which the train decelerates to station B = 2 minutes = 0.0\(\bar 3\) hours

The equation of motion required are;

The initial acceleration, a = (144 - 0)/0.05 = 2,880 km/h²

The distance covered, s = u·t + 1/2·a·t²

Where;

u The initial velocity = 0

∴ s₁ = 0 × 0.05 + 1/2 × 2880 × 0.05² = 3.6 km

s₁ = 3.6 km

The distance, s₂ the train covers at the constant speed 144 km/h for 10 minutes (1/6 hours) is given as follows;

s₂ = Velocity Time = 144 × 1/6 = 24 km

s₂ = 24 km

The deceleration, a₂ that brings the train to a stop in 2 minutes (1/30 hours) is given as follows;

a₂ = (0 - 144)/(1/30) = -4320 km/h²

The distance covered, s₃ by the train as it decelerates to rest from the initial constant speed is given as follows;

s₃ = u·t + 1/2·a·t²

Where;

u = The initial velocity =144 km/h

We have;

s₃ = 144×1/30 - 1/2 × 4320 × (1/30)² = 2.4

s₃ = 2.4 km

The total distance between A and B, s = s₁ + s₂ + s₃ = 3.6 + 24 + 2.4 = 30 km

The total distance between A and B = 30 km.

Explanation:

Force = mass x acceleration

F= ma (formula)

15N = o.5kg x a

Divide both sides by o.5

a = 30 (greater acceleration)

15N = 4.5kg x a

Divide both sides by 4.5

a= 3.33 (great acceleration)

15N = 0.05kg x a

Divide both sides by 0.05

a = 300 (greatest acceleration)

The magnetic field at 10.76 m below the high voltage power line is approximately 41,835,820 µT when the line carries 450 MW at a voltage of 300,000 V. Rounded to the nearest integer, the magnetic field is 41,836 µT.

To calculate the magnetic field at a distance below a high voltage power line, we use the formula \(B=\frac{u0IH}{2\pi r}\)

Current, I = 450 MW = 450 × 10^6 W

Height, H = 0 m (since the power line is at ground level)

Distance below the power line, r = 10.76 m

Using the formula for the magnetic field, we substitute the given values:

\( B = \frac{{(4\pi \times 10^{-7} \, \text{{T}} \cdot \text{{m/A}}) \cdot (450 \times 10^6 \, \text{{W}}) \cdot (0 \, \text{{m}})}}{{2\pi \cdot 10.76 \, \text{{m}}}} \)

Simplifying the expression:

\( B = \frac{{450 \times 10^6 \, \text{{W}}}}{{10.76 \, \text{{m}}}} \)

Calculating the value:

\( B \approx 41,835,820 \, \text{{T}} \)

Rounding the magnetic field to the nearest integer:

\( B \approx 41,836 \, \mu\text{{T}} \)

Therefore, the magnetic field at 10.76 m below the high voltage power line is approximately 41,836 µT (rounded to the nearest integer).
