Answer:

B. The medium increases in temperature while remaining in the same phase

Explanation:

Good luck on all your tests and Exams!

The sound wave will increase when the medium increases in temperature while remaining in the same phase.

Sound waves are composed of compressions and rare factions. Sound is a mechanical wave hence it moves by the vibration of air particles.

As such, the sound wave will increase when the medium increases in temperature while remaining in the same phase.

ADVANTAGES OF TISSUE CULTURE

There are several advantages to using the tissue culture process. We already mentioned its effectiveness in helping developing countries to increase food production, but what are some other advantages that may be relevant to you?

The new plantlets can be grown in a short amount of time.

Only a small amount of initial plant tissue is required.

The new plantlets and plants are more likely to be free of viruses and diseases.

The process is not dependant on the seasons and can be done throughout the year.

You need only a relatively small space to perform the process (ten times the plants in one-tenth of the space).

On a larger scale, the tissue culture process helps to supply the consumer market with new subspecies and variety.

People looking to cultivate challenging plants such as specific breeds of orchid find more success with the tissue culture process than traditional soil.

DISADVANTAGES OF TISSUE CULTURE

Tissue Culture can require more labor and cost more money.

There is a chance that the propagated plants will be less resilient to diseases due to the type of environment they are grown in.

It is imperative that, before being cultured, the material is screened; failure to pick up any abnormalities could lead to the new plants being infected.

While the success rate is high if the correct procedures are followed, success with the tissue culture is not a guarantee. There is still a chance that the process triggers a secondary metabolic chemical reaction, and the new explants or cells' growth gets stunted, or even die off.

Answer:

ln physics, Rest is the state at which an object is stationary or not moving with respect to its surroundings, and is said to be at rest. An example would be a book lying on a table.

Answer:

When an object does not change it's position with respect to time it is said to be at rest.

Explanation:

Example- A person sitting on a chair or a book lying on a table.

Please note there is no such thing as absolute rest.

Take the example of a person A sitting in a moving bus. If the observer is in the bus then to him person A is at rest. However if the observer is is outside the bus then person A is in motion as the bus is moving.

Please mark me as brainliest.

Answer:

Critical angle

Explanation:

The angle of incidence when the refracted angle is 90°; we have the critical angle at this point. At this point, the refracted ray lies between the boundary between the two medium, this is the angle just before total internal reflection occurs, as the refracted angle exceeds 90°, all rays are reflected. Hence, we can conclude that it is the largest angle at which reflection can still occur.

The one on the left

Explanation:

Answer:

Explanation:

This one-dimensional equation is just a fancy way of saying d = rt. Filling in:

d = 12.0(20) so

d = 240 m

Speed = Distance/Time

Now,

35 = 120/t

35/120 = 1/t

120/35 = t

3.42 hours = t

Answer:

3000 kg*m/s

6000 kg*m/s

Explanation:

p = m*v

p = 150kg*20m/s

p = 3000 kg*m/s

p = 150kg*40m/s

p = 6000 kg*m/s

Answer:

As an object moves faster, its mass increases. ... Because masses approach infinity with increasing speed, it is impossible to accelerate a material object to (or past) the speed of light. To do so would require an infinite force.

Answer:

(C) 700 N

Explanation:

The given parameters are;

The mass of the mountain climber, m = 100 kg

The angle formed by the rope with the horizontal, θ = 45°

The gravitational field strength, g = 10 N/kg

The weight of the man, W = m × g

∴ W = 100 kg × 10 N/kg = 1,000 N

At equilibrium, we have;

The downward force, the weight of the man, W = The upward force, the vertical component of the tension on the two halves of the rope

We have;

W = T × sin(θ) + T × sin(θ)

∴ 1,000 N = 2 × T × sin(45°)

Therefore, we have;

T = 1,000 N/(2 × sin(45°)) = 707.106781 Newtons

Therefore, the tension in the rope is closest to (approximately) 700 N.

Answer:

The amount saved in a year is $ 278.6.

Explanation:

current, I = 0.275 A

Voltage, V = 120 V

cost = $ 0.20 per kWh

The energy spent in 1 year is given by

E = V I t

E = 120 x 0.275 x 365 x 24 x 3600

E = 1.04 x 10^9 J

1 kWh = 3.6 x 10^6 J

So,

E = 288.9 kWh

So, the cost is

C = $ 0.2 x 288.9 = $ 57.78

So, the amount saved = $ 336.384 - $ 57.78 = $ 278.6

water cycle show the continuous movement of water with in the earth and atmosphere

Explanation:

Hope this helps :)

The water cycle is the process through which water evaporates from the earth's surface, rises into the atmosphere, cools and condenses into rain or snow in clouds, and then falls back to the surface as precipitation. Water that falls on land gathers in rivers and lakes, soil, and porous rock strata, and much of it goes back into the seas to evaporate. Water flows in and out of the system.

Answer:

Current = 3 Amperes

Explanation:

Given the following data;

Quantity of charge = 6 C

Time = 2 seconds

To find how many amps are moving through this wire;

Mathematically, the quantity of charge passing through a conductor is given by the formula;

Quantity of charge = current * time

Substituting into the formula, we have;

6 = current * 2

Current = 6/2

Current = 3 Amperes

Answer:

Gamma rays

Explanation:

gamma rays have the highest energy and the shortest wavelength

Average speed = total distance/time

That's 2.62 m/s .

You don't want average displacement. You want average velocity.

That's (displacement)/(time).

That's zero, because displacement = 0.
