Which biome contains mostly coniferous trees and receives 35 to 100 cm of rain per year?

Answers

The question is incomplete as it does not have the options which are:

deciduous forest

taiga (boreal forest)

temperate rainforest

tropical rainforest

Answer:

Taiga (boreal forest)

Explanation:

A Biome refers to the habitat which is occupied by flora and fauna living in similar conditions.  These biomes are distinguished based on many features like precipitation, temperature and many other physical factors.

In the given question, the biome which receives an annual rainfall of 35 to 100 cm annually and is mostly covered by the coniferous trees is known as "Taiga biome" which is also known as Boreal forest.

The Taiga biome is one of the largest terrestrial biomes which is present in Eurasia and North America. The biome is characterised by the conifers trees and therefore is also known as the Coniferous trees.

Thus, Taiga (boreal forest) is the correct answer.

What is the critical angle for glass when the refractive index is 1.45

Answers

Answer:43.6°

Explanation:

Refractive index=n=1.45

Critical angle=c

n=1/sinc

1.45=1/sinc

Cross multiply

1.45sinc=1

Divide both sides by 1.45

(1.45sinc)/1.45=1/1.45

sinc=0.6897

c=sin(inverse)(0.6897)

c=43.6°

Critical angle is 43.6°

Answers

Answer:

 R (120) = 940Ω

Explanation:

The variation in resistance with temperature is linear in metals

           ΔR (T) = R₀ α ΔT

where α is the coefficient of variation of resistance with temperature, in this case α = -0,0005 / ºC

let's calculate

            ΔR = 1000 (-0,0005) (120-0)

            ΔR = -60 Ω

            ΔR = R (120) + R (0) = -60

            R (120) = -60 + R (0)

            R (120) = -60 + 1000

            R (120) = 940Ω

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas

v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1)

where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E

Answers

The first and second velocities of the car, with four washers attached to the pulley, are both 0.125 m/s.

We must apply the following calculations to determine the car's first and second velocities with the four washers attached to the pulley:

v1 = 0.25 m / t1

v2 = 0.25 m / (t2 - t1)

Here, t1 denotes the typical time needed for the car to go 0.25 metres, and t2 is the typical time needed to travel 0.50 metres.Let's say that t1 and t2 are the typical times, each lasting two seconds on average.The first formula allows us to determine v1:

v1 = 0.25 m / 2 s = 0.125 m/s

Using the second formula, we can calculate v2:

v2 = 0.25 m / (4 s - 2 s) = 0.125 m/s

Table E can be used to record these values as the velocities at the relevant distances.

Object A has a mass of 10 kg and is moving at a velocity of 2.0
m/s. So Object A's momentum is - kg. m/s.​

Answers

Answer:20kgm/s

Explanation:

Mass=10kg

Velocity=2m/s

Momentum=mass x velocity

Momentum=10 x 2

Momentum=20

Momentum=20kgm/s

The object with mass m when moving with the velocity, its momentum can be calculated. The momentum of the object A is 20 kg.m/s.

What is momentum?

Momentum is the product of mass and velocity of a moving object.

If the momentum is p, the mass of the object is 10 kg and the velocity is 2.0 m/s, then the momentum will be

p = 10 × 2.0

p = 20 kg.m/s

Thus, the momentum of the object A is 20 kg.m/s

Refer to the model below. A science student is camping with her family for one month at Stone Mountain Park. In a journal she records a model of the moon phases she observes. If she began recording the moon phases at position X, which sequence of Moon phase models could be seen by her during the 4-week period?

Answers

Answer:

New Moon - Crescent Moom ---- Full Moon ---- Waning Quarter

Explanation:

The Moon revolves around the Earth in a 28 day period, which is approximately one Earth month, therefore S the student has been recording the movement of the Moon for 4 Earth weeks this is a period of complete revolution of the Moon .

Consequently you must register the following phases

New Moon - Crescent Moom ---- Full Moon ---- Waning Quarter

in the period where it begins, it must go through the cycle in an orderly way to the right.

You have a large flashlight that takes 4 D-cell batteries, each with a voltage of 1.5 volts. If the current in the flashlight is 2.0 amps, what is the
resistance?
A 12 ohms
B 0.75 ohms
C 3.0 ohms
D.0.5 ohms
E. 6.0 ohms

Answers

Answer:

The answer is "C. 3.0 ohms". 

Explanation:

Ohm's law states the following:,

V = IR

where:

Voltage (V) = 1.5 volts × 4 batteries = 6.0 volts

Current (I) = 2.0 amps

Resistance (R) = ? ohms

To solve for Resistance (R) the equation must be rearranged this way:

 R = V / I

Then, the variables must be replaced with the known values:

 R = 6.0 volts / 2.0 amp

R = 3.0 ohms

The answer is  C. 3.0 ohms.
