Answer: As you already know people have cloned dolly sheep but what about people? will we be able to clone ourselves one day?. Good question, actually scientist believe it may be possible years from now, though it wouldn't be right if we didn't research. It is hard to clone animals let alone people which is probably one of the reason's some human's oppose it so much. Think of it this way though if we cloned ourselves or someone clones us after we die it'll be like we never left. It will bring less heart-ship to people knowing can always have that person. it will also make life more evolved in evolution and theory.

Question 5 options:
Cold Front
Stationary Front
Warm Front
Occluded Front
1.
When a cold air mass and a warm air mass meet but are at a standstill, the boundary is called
2.
If warm or more humid air presses forward and colder or drier air draws back, the boundary is called
3.
If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called
4.
Sometimes a warm air mass can get caught between two cold fronts, which can force the warm air up into a wedge shape.
Answer:
Cold Front 3 // Stationary Front 1 // Warm Front 2 // Occluded Front 4
Explanation:
It's simple. Warm front means the warm air is pressing forward, which is why it's a warm front. Stationary Front, meaning they're at a standstill, also makes sense because stationary means not moving. Then since your last option is Occluded Front, since the others already have an answer, you have no choice but to match 4 with it. I took the quiz and got the answer right. :D

In the lab, You have a highly reactive metal like sodium. It is so reactive that water sets it off. How would you store it?
Answer:
Sodium is stored under paraffin oil
Explanation:
Group 1 metals are known to be very highly reactive. The chemical reactivity of the members of the group decreases down the group.
Sodium reacts violently with water and upon exposure to the atmosphere. As a result of this, it must be stored under paraffin oil.
Which statement about the Law of Conservation of Mass is NOT true? A. Although the molecular makeup of molecules may change, the atoms are not lost. B. Matter is neither created nor destroyed during a chemical change. C. Chemical reactions create new atoms, which will increase the mass of the substance.
Answer:
C. Chemical reactions create new atoms, which will increase the mass of the substance.
Explanation:
It is not true that according to the Law of conservation of mass that mass of the substance will increase during chemical reactions.
During a chemical reaction, new atoms are not being created. The atoms of the reactant simply recombines to given a different product or compound. The atoms are still the same only the compound or product form differs.
According to the law of conservation of mass "in a chemical change, matter is neither created nor destroyed but bonds are broken and atoms combine".
By virtue of this, chemical reactions conserves mass so that the mass we start with is the same we end with since no new matter is destroyed nor created.

A spring with a spring constant of 400 n / M has a mass hung on it so it stretches 8 cm. calculate how much mass the spring is supporting.
Answer:
3.3kg
Explanation:
Given parameters:
Spring constant = 400N/m
Extension = 8cm = 0.08m
Unknown:
Amount of mass the spring is supporting = ?
Solution:
To solve this problem:
F = kE
F is the force
k is the spring constant
E is the extension
So;
F = 400 x 0.08 = 32N
Mass;
Force = mass x acceleration due to gravity
32 = mass x 9.8
Mass = 3.3kg
The mass the spring is supporting is 3.27 Kg.
We'll begin by calculating the force acting on the spring.
Spring constant (K) = 400 N/mExtension (e) = 8cm = 8 / 100 = 0.08 mForce (F) =?F = Ke
F = 400 × 0.08
F = 32 N
Finally, we shall determine the mass. This can be obtained as follow:
Force (F) = 32 NAcceleration due to gravity (g) = 9.8 m/s²Mass (m) =?m = F / g
m = 32 / 9.8
m = 3.27 Kg
Therefore, the mass the spring is supporting is 3.27 Kg

A train moves from rest to a speed of 25 m/s in 30.0 seconds. What is the acceleration?
Answer:
[tex]a = 0.83\ m/s^2[/tex]
Explanation:
Uniform Acceleration
When an object changes its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
[tex]v_f=v_o+a.t[/tex]
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
It's known a train moves from rest (vo=0) to a speed of vf=25 m/s in t=30 seconds. It's required to calculate the acceleration.
Solving for a:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
Substituting:
[tex]\displaystyle a=\frac{25-0}{30}[/tex]
[tex]\boxed{a = 0.83\ m/s^2}[/tex]

PLS HELP! A boy drops a ball from an observation tower. The ball hits the ground in 3.0 s. What is the ball's velocity at the time of impact?
Answer:
v = u + at
v = 0 + 9.8 × 3
v = 29.4 m/sec
Answer: 29.4 m/s
Explanation:
We find the answer by using this equation:
v2 = v1 + a * t
Let's figure out what our variables are.
v2 = ?
We don't know the final velocity, so this variable is blank
v1 = 0
In a free fall, the velocity is 0
a = 9.8 m/s
Acceleration in a free-fall is 9.8 m/s
t = 3
It took 3 seconds for the ball to hit the ground
Now we plug our values.
v2 = v1 + a * t
v2 = 0 + 9.8 * 3
v2 = 0 + 29.4
v2 = 29.4
Hope this helps! :)

A crane lifts a 3,000 kg beam of concrete from the ground to a height of 50m. What work is being done on the concrete?
Answer:
The work done on the concrete is 1,470,000 J
Explanation:
Given;
mass lifted by the crane, m = 3,000 kg
height through which the mass was lifted, h = 50 m
The work done on the concrete is equal to the gravitational potential energy of the concrete due to the height it was raised.
E = W = mgh
W = mgh
W = 3000 x 9.8 x 50
W = 1,470,000 J
Therefore, the work done on the concrete is 1,470,000 J

If a small planet were located 8.0 times as far from the sun as the Earth is, how many years would the planet take to orbit the sun?
Answer:
the time period is 22.63 years
Explanation:
The computation of the number of years taken is as follows:
According to the Keplers law
[tex]T^2 \propto R^3[/tex]
Here T denotes the time period
And, R denotes the average distance among the sun and planet
Now let us assume for earth
R_1 & T_1 be 1 year
So, for Planet
[tex]R_2 = 8R_1 , T_2 = ?[/tex]
Now applied Keplers law
[tex](\frac{T_2}{T_1})^2 \propto (\frac{R_2}{R_1})^3\\\\(T_2)^2 = (\frac{8R_1}{R_1})^3 \times 1^2\\\\(T_2)^2 = 512\\\\T_2 = 22.674[/tex]
So, the time period is 22.63 years

Why do clouds and precipitation contain freshwater even though much of the water vapor comes from oceans and seas?
The atmosphere filters out the salt as precipitation is created
Most of the water doesn't come from the ocean, it comes from fresh water sources
Precipitation does contain 72% salt water
When water evaporates from the ocean, the salt is too dense to evaporate
Answer:
★ Most of the water doesn't come from the ocean, it comes from fresh water sources
Explanation:
Hope you have a great day :)
Most of the water doesn't come from the ocean, it comes from fresh water sources.
When water vapor in the sky condenses into droplets and hits the ground, rain is created. Although saltwater does turn into water vapor during the evaporation process, freshwater makes up the droplets that form in clouds. This is so that only the salt is left behind after the process of evaporation separates the freshwater from the saltwater.
The water vapor rises and cools, forming droplets that are virtually totally composed of freshwater when they condense.
The droplets that are heavy enough to defeat evaporation and fall as rain are the ones that make it to the earth.
Precipitation is the natural method of removing salt from water and creating fresh water.
