The statement “All of the earth's life and weather exists within the stratosphere” is absolutely false. Thus, the correct option for this question is B.
Stratosphere may be defined as the second layer of the atmosphere as you go upward. It is the layer of the earth's atmosphere above the troposphere. Apart from this, it significantly extends to about 50 km above the earth's surface.
According to the context of this question, the correct and absolute answer is the troposphere. It is the first layer that is where we are able to do most of our activities. This is where we can see the formation of clouds, and the production of rain, hail, snow, and other weather phenomenon.
The troposphere is essential as it contains the Earth's weather as well as greenhouse gases to maintain the temperature on Earth. The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
Therefore, the statement “All of the earth's life and weather exists within the stratosphere” is absolutely false. Thus, the correct option for this question is B.

The statement “All of the earth's life and weather exists within the stratosphere” is false. The answer is letter B. The answer is the troposphere. The first layer, troposphere, is where we are able to do most of our activities. This is where we can see the formation of clouds, the production of rain, hail, snow and other weather phenomenon. Also, this layer is where the greatest amount of air pressure because most of the molecules of air are in this area. Like us, air has also mass and the pressure is brought down by the earth’s gravity causing an increase in weight exerted on you as you descend lower into the atmosphere. So, as you enter into the other layers of atmosphere above the troposphere, the air pressure starts to decrease. Below the atmosphere is the hydrosphere. This is where all liquid forms are located. And since the seawater has a greater mass than air, it has the greatest pressure.
Answer:
False
Explanation:
Inattentionla blindness is a condition that happens when you overview or do not notice an object that is not supposed to be in a certain place and that is strange for its context because you are paying attention to something else, this means that if you do a task that needs a great deal of attention you will actually increase the inattentional blindness.
The correct answer is F
Answer:
0.432kg or 432g
Explanation:
Copper block is removed from 310C oven.
Mass of water = 1.10kg
Initial temperature of water (θ1) = 23.0C
Final temperature of water (θ2 ) = 33.0C
Specific heat of copper= 385
Specific heat of water = 4190
Let M (copper) be the mass of copper
The amount of heat lost will be absorbed by water
Q (net) = Q(water) + Q(copper) = 0 …………………(1)
Q = MCθ
For water,
Q(water) = M(water) * C(water) * (θ2-θ1)...........(2)
= 1.1 * 4190 * (33.0 -23.0)
= 1.1 *4190 * 10
= 46090J
For copper,
Q(copper) = M(copper) * C(copper) * (33.0 - 310)...........(3)
from equation 1,
Q(copper) = -Q(water)
M(copper) * C(copper) * (33.0 - 310) = - 46090
M(copper) * 385 * (-277) = -46090
M(copper) * 106645 = -46090
M(copper) = -46090 / -106645
M(copper) = 0.432kg
M(copper) = 432g
The mass of copper =432g
The mass of the copper block is 3.69kg.
To find the mass of the copper block, we can use the equation q1 = q2. The heat gained by the water is given by q1 = mcΔT, where m is the mass of the water, c is the specific heat of water, and ΔT is the change in temperature. The heat lost by the copper block is given by q2 = mcΔT, where m is the mass of the copper block, c is the specific heat of copper, and ΔT is the change in temperature. Since the water reaches a final temperature of 33.0°C, the change in temperature is ΔT = 33.0°C - 23.0°C = 10.0°C.
Using the equation q1 = q2, we have mcΔT = mcΔT. Rearranging the equation to solve for the mass of the copper block, we get m = (m1c1ΔT2) / (c2ΔT1), where m1 is the mass of the water, c1 is the specific heat of water, ΔT2 is the change in temperature of the copper block, c2 is the specific heat of copper, and ΔT1 is the change in temperature of the water. Substituting the given values, we have m = (1.10kg * 4190 J/(kg?K) * 10.0°C) / (385 J/(kg?K) * 10.0°C), which simplifies to m = 3.69kg.

b. iron
c. stony
d. Kuiper
The types of meteorites are iron, stone and iron-stony meteorites. The stony-iron meteorites account for less than 2% of all known meteorites. They comprised of roughly equal amounts of nickel-iron and stone and are divided into two groups: pallasites and mesosiderites. The answers are only B and C

Answer:
A.) 12.5 J
B.) 12.5 J
C.) 7.1 m/s
Explanation:
Given that a 0.5 kg object, initially at rest, is pulled to the right along a frictionless horizontal surface by a constant horizontal force of 25 N for a distance of 0.5m.
a. What is the work done by the force?
Work done = force × distance
Work done = 25 × 0.5
Work done = 12.5 J
b. What is the change in the kinetic energy of the block?
Work done = energy
Change in Kinetic energy = work done
Change in kinetic energy = 12.5 J
c. What is the speed of the block after the force is removed?
Kinetic energy = 1/2mV^2
12.5 = 1/2 × 0.5 × V^2
25 = 0.5V^2
V^2 = 25/0.5
V^2 = 50
V = 7.1 m/s
