Responses


a Increased oxygen allowed reptiles to thrive.

b Helium and hydrogen gases escaped Earth's gravity.

c Heat energy was retained, and water vapor condensed.

d Ultraviolet light split water vapor into hydrogen and oxygen.

Answers

Answer 1

During the third atmosphere on Earth, the same effect on Earth as it did on Mars. Heat energy was retained while water vapor was condensed.

What was the third atmosphere of Earth-like?

The third atmosphere on the planet was created by volcanic outgassing and comet ice. This atmosphere had no oxygen, but plenty of carbon dioxide, water vapor, nitrogen gas, and methane gas.

When Earth's crust started to cool 2.5 billion years ago, there was less water vapor in the atmosphere, and more water condensed as liquid, resulting in the formation of Earth's third atmosphere.

This atmosphere was produced by volcanic outgassing, and it was the first to survive on Earth. A planet's atmosphere did not form through accretion while the formation of the planet's star.

Instead, its atmosphere forms as a result of internal volcanic activity or the aggregation of material from comet impacts.

Explain how the energy from the sun is transferred to fossil fuel?

Answers

Answer:

Fossil fuels are energy sources that come directly from nature. First, the sun's radiant energy is stored as chemical energy in plants by photosynthesis. When the plants die, they start decaying. After many years, the plants are turned into fossil fuels.

Explanation:

Fossil fuels rely on the Sun's energy because the energy in fossil fuels came from plants and algae as they performed photosynthesis, which requires sunlight.

When sunlight strikes a plant, some of the energy is trapped through photosynthesis and is stored in chemical bonds as the plant grows.

A cheetah can run from 0 to 70 mph in 2.2 seconds. How much distance did the cheetah cover in traveling from 0 to 70 mph?

Answers

The top speed of a cheetah in m/s is 31.29 m/s.

Given data:

The initial speed of a Cheetah is, u = 0 mph.

The final speed of the Cheetah is, v = 70 mph.

The time interval is t = 2.2 seconds.

We are already given with top speed of a Cheetah, and it’s none other than the final speed itself. Now we need to convert the mph value of top speed into m/s value.

We know that,

1 mph = 0.44704 m/s

So, the value of 70 mph in m/s is,

Thus, we can conclude that the top speed of a cheetah in m/s is 31.29 m/s.

How to calculate the pressure of water

pressure of water at a certain depth is calculated using the formula

Pressure, P = height * density * acceleration due to gravity

density of water is given by = 1000 kg/m³

acceleration due to gravity is given by = 9.82 m/s²

the given height, at the bottom of the 54-m-high water tower  = 54 m

Pressure = 1000 kg/m³ *  9.82 m/s² * 54 m

Pressure = 530280 N/m²

You may use string, plastic bags, paper, and any fabrics you have to make a model parachute.

Identify the criteria and constraints. Describe your model and draw a picture of it. Describe how you could test your model and what you would do after the first test.
(pls make don't talk about high school)

Answers

The criteria for a successful parachute system are that it must be able to safely land the camera without breaking any of the eggs. The constraints are that the parachute must be made using only string, plastic bags, paper, and fabrics, and the camera must be modeled using a carton of eggs.

One possible model for the parachute system could be a square parachute made of paper or fabric, with strings attached to the corners of the parachute. The camera (represented by the carton of eggs) would be attached to the center of the parachute.

To test the model, we could drop the parachute and camera from a height of one story (or a similar height) and observe whether the eggs break upon landing. If the eggs do not break, the parachute system is considered successful.

After the first test, we could make changes to the design of the parachute (such as changing the shape or size, or adding more strings) and test it again to see if it performs better. We could continue making and testing different designs until we find a parachute system that meets the criteria and constraints.

The frictional force of an object is the product of the normal force and coefficient of kinetic friction. Here the frictional force acting on the object  is 16.4 N.

What is frictional force?

Frictional force is a kind of force acting on a body to resist it from motion. Thus, the direction of the force will be in negative with the magnitude. Frictional force is the product of coefficient of friction and the normal force.

The normal  force acting on the object of mass 4.2 Kg is N = mg

N = 4.2 Kg × 9.8 m/s² = 41.16 N

Frictional force = ц N

Obviously only one, HHHHH, and our equation gives 5!/[5!0!]=1, using the standard definition that 0! is defined to equal 1 If the coin is equally likely on a single throw to come up heads or tails, any specific sequence like HTHHT or HHHHH is equally likely. However, there is only one way to get HHHHH, while there are 10 ways to get 3 heads and 2 tails, so this is 10 times more probable than getting all heads.
