Answer:

Average speed = 53.33 km/h

Explanation:

Below is the calculation for the average speed:

Given the average speed of for first 40 km = 80km/h

Time taken to cover the first 40 km = Total Distance / average speed

Time taken to cover the first 40 km = 40 / 80 = 0.5 hours

Given the average speed of for next 40 km = 40km/h

Time taken to cover the next 40 km = Total Distance / average speed

Time taken to cover the next 40 km = 40 / 40 = 1 hours

Now the average speed of the tuck to cover total distance:

Average speed = Total distance / Total time

Average speed = (40 + 40) / (0.5 + 1)

Average speed = 53.33 km/h

If I move 3 m east and 4 m north, then my displacement would be 5m.

In geometry and mechanics, displacement is defined as a vector whose length is the shortest distance from initial to the final position of a point P undergoing the motion.

If an object moves relative to the reference frame—for example, if professor moves to the right relative to whiteboard or passenger moves toward the rear of airplane—then object's position changes. And this change in position is known as displacement.

Given AB= 3m east and BC= 4m north

AC= √ 3² + 4²= 25

So, AC, displacement = 5m

A joint is not a wave-like undulation of rock layers in response to stress. False statement.

Instead, a joint is a type of fracture in rocks where there has been no significant displacement. The wave-like undulation you are referring to is called a fold, which occurs when rock layers are compressed and deformed under stress

A joint is a type of fracture or break in rock that occurs when there is no movement between the two sides of the fracture. Joints are formed in response to stresses such as tectonic activity or changes in temperature and pressure and are a common feature in many types of rocks.

While joints can sometimes give the appearance of a wave-like undulation in rock layers, this is not the same as a true wave-like undulation such as a fold or a fault. Folds are undulations in rock layers that result from compressive stresses that cause the layers to bend and deform, while faults are fractures in the rock where the movement has occurred along one side of the fracture relative to the other.

The dishwasher would need to transfer 480 kJ of energy for 400 seconds, or 6 minutes and 40 seconds.

Power is determined by the product of force, velocity, and distance traveled (in the force's direction). For those looking to enter the teaching profession in the state of Uttar Pradesh, this is a fantastic opportunity. Voltage and current together produce electrical power P=VXI.

time = energy / power

480 kJ = 480,000 J

time = energy / power

time = 480,000 J / 1200 W

time = 400 seconds

Hence, for the dishwasher to transfer 480 kJ of energy, it would take 400 seconds, or 6 minutes, 40 seconds.

A substance or thing that creates a magnetic field is called a magnet. The most noteworthy characteristic of a magnet—a force that pulls on other ferromagnetic elements, such as iron, steel, nickel, cobalt, etc.—as well as the ability to attract or repel other magnets—is caused by this invisible magnetic field. An object made of a substance that has been magnetized and produces its own persistent magnetic field is referred to as a permanent magnet. A common example is a refrigerator magnet used to keep notes on the door of the refrigerator.

6 feet deep is a fathom .

What is fathom ?

A fathom is a unit of length that is used primarily to measure the depth of water in nautical and maritime applications. It is equivalent to 6 feet (1.83 meters) and is used to describe the depth of water in terms of the distance from the surface of the water to the ocean floor.

The word "fathom" comes from the Old English word "fæðm," which means "the outstretched arms." The term was used to describe the length of a human outstretched arms, which was approximately 6 feet.

In nautical and maritime applications, fathoms are used to measure the depth of water in harbors, shipping lanes, and other areas where ships and boats operate. This information is important for navigation, as it helps sailors and mariners to avoid shallow waters and potential hazards.

Answer:

To calculate the average acceleration of the particle, we use the formula a = (vf - vi)/t, where vf is the final velocity, vi is the initial velocity, and t is the time interval. In this case, a = (18.0 m/s - 29.0 m/s)/11.5 s = -2.3 m/s2. Therefore, the average acceleration of the particle is -2.3 m/s2.

Interstellar dust scatters and absorbs light from stars, causing them to appear redder and dimmer than they would without dust.

Interstellar dust is made up of tiny particles, ranging from a few molecules to a few micrometers in size, that are found throughout the interstellar medium. When light from a star passes through the dust, it can be scattered in many different directions or absorbed by the dust particles.

This causes the starlight to appear dimmer and redder than it would be without dust. The reddening occurs because dust scatters blue light more efficiently than red light, causing blue light to be preferentially absorbed.

The overall effect of interstellar dust is known as extinction, which can make it difficult for astronomers to observe and study distant stars and galaxies.

The pressure exerted on an object under 0.76 meters of mercury is 101,292.8 Pascals

Pressure is defined as force exerted per unit area.

P = F/A

Where:

F = force

A = area

In this case the force is the gravitational force or weight.

w = mg

where m = mass of the substance

Since mass is equal to density times volume:

m = ρ . V

Hence,

P = mgh/A = ρgh

Where:

ρ = density of the substance.

The parameters in the problem are:

ρ = density of mercury = 13,600 kg/m³

The number of structural subunits present in a nucleoside and a nucleotide are, respectively, two and three. The correct option is c).

A nucleoside consists of two main structural subunits: a nitrogenous base and a sugar molecule. The nitrogenous base can be adenine (A), guanine (G), cytosine (C), or thymine (T) in DNA (or uracil (U) in RNA). The sugar molecule in a nucleoside is typically ribose in RNA or deoxyribose in DNA. So, a nucleoside is composed of a nitrogenous base and a sugar molecule, making it a combination of two structural subunits.

On the other hand, a nucleotide consists of three main structural subunits: a nitrogenous base, a sugar molecule, and a phosphate group. The phosphate group is attached to the sugar molecule, forming a sugar-phosphate backbone. Therefore, a nucleotide is composed of a nitrogenous base, a sugar molecule, and a phosphate group, making it a combination of three structural subunits.

In summary, a nucleoside has two structural subunits (a nitrogenous base and a sugar molecule), while a nucleotide has three structural subunits (a nitrogenous base, a sugar molecule, and a phosphate group). Thus, the correct answer is option c) two and three.
