SpongeBob noticed that his favorite pants were not as clean as they used to be. His friend, Sandy, told him that he should try using Clean-O detergent, a new brand of laundry soap she found at Sail-Mart. SpongeBob made sure to wash one pair of pants in plain water and another pair in water with the Clean-O detergent. After washing both pairs of pants three times each, the pants washed in the Clean-O detergent did not appear to be any cleaner than the pants washed in plain water. 1) What was the problem SpongeBob wanted to investigate? 2) What was the problem SpongeBob wanted to investigate? 3) What is the dependent variable? 4) What should be SpongeBob’s conclusion?
Answers
Answer:
1) SpongeBob investigated whether Clean-O detergent is a good laundry soap. 3) the dependent variable is the color of the pants/how clean the pants were. 4) SpongeBob's conclusion should be that Clean-O detergent is not a good detergent.

An artificial biosphere is an enclosed area that contains the elements necessary for human life to exist. Suppose scientists want to develop an artificial biosphere on a new planet. The new planet has an atmosphere that is 96% carbon dioxide with only trace amounts of oxygen. What could humans do to make enough oxygen to survive? Explain your answer.
Answers
Answer: humans would need an A.I. to artificially create more than enough oxygen to survive
Explanation: well if the planet is 96% carbon dioxide and 4% oxygen then in the matter of days they would get really sick from breathing in excess carbon dioxide. so they would need an A.I to somehow make enough oxygen needed for everyone in the planet to survive, and they also wouldn't be able to drink water since there is only 4% of water because water is made of one oxygen atom and 2 hydrogen atoms.
In order to implement photosynthesis on the new planet, humans would need to cultivate plants and microorganisms that are capable of surviving in the extreme conditions of the new planet's atmosphere. These organisms would need to be able to tolerate high levels of carbon dioxide and low levels of oxygen while also being able to thrive in the artificial biosphere's enclosed environment.
The cultivation of plants and microorganisms capable of photosynthesis would require a carefully controlled environment with the appropriate levels of light, temperature, and nutrients. It would also require a system for regulating the levels of carbon dioxide and oxygen in the atmosphere of the artificial biosphere to ensure that the plants and microorganisms have access to the necessary gases for photosynthesis.
Once established, the plants and microorganisms would convert the carbon dioxide in the atmosphere into oxygen, providing a sustainable source of breathable air for the human inhabitants of the artificial biosphere.

You have a board, wood blocks, and a toy car. Your goal is to build a ramp that sends the car as far across the floor as possible. What angle between the board and floor would be best? Explain your answer
Answers
Answer:
The board should be placed at about an 80-88 degrees angle.Explanation:
This will speed the car up and increase its speed as going down the ramp.
Potential and Kinetic Energy
Set up a basic ramp against a chair, on top of some books, or from a table to the floor. Hold the car at the top of the ramp, and release to demonstrate the two main kinds of energy. Potential energy is placed into the car when it's lifted from the floor, and that energy is released as the car rolls down the ramp. Ramps should be made of a solid, smooth and rigid material such as wood or plywood.
Friction
Using the ramp from earlier, you can make a more interesting experiment by placing some things at the bottom. Drop the car from the top of the ramp again, and measure how far it rolls this time. Now, place a sheet of cardstock at the bottom of the ramp, and let the car roll over that. Measure the distance it rolls. Place some sandpaper on top of the card stock, release the car, and measure that distance. Finally, try it with some carpet at the bottom. You've now learned something about friction: the card stock has a lot less friction than the carpet, so the car should be able to roll farther.
Inertia
Place a heavy stack of books a few feet from the end of the ramp, so that the car hits those books when it rolls from the top down. Demonstrate that once or twice, and then take a small ball of clay or putty. Place it on top of the car and pat it down slightly; don't squish it onto the car, but press it just enough so that it won't roll off. Roll the car down the ramp, and when it hits the books, the clay should fly off the front of the car. This happens because of Newton's first law of motion: anything moving is going to want to keep moving (until it crashes into a wall).
Angle
The optimal angle for the board is about 80⁰

Newton's second law of motion is F = ma.
A net force of 60 N north acts on an object with a mass of 30 kg. Use Newton's second law of motion to calculate the amount of acceleration the object will experience. Then explain how the amount of acceleration will change if the net force or the mass of the object increases?
Answers
Answer: The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.
Explanation:
Force is defined as the product of object's mass and acceleration.
Mathematically,
F = ma ......(1)
or,
a = F/m .....(2)
where,
F = Force exerted on an object = 60N
m = mass of an object = 30kg
a = acceleration of the object = ?
Putting values in above equation, we get:
a = 60 kg.m/s^2/30 kg = 2m/s^2
The acceleration of the car is 2m/s^2.
From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.
And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.
Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.
A net force of 60 N north acts on an object with a mass of 30 kg , so according to Newton's second law of motion the acceleration of the object would be 2 m / s²,the amount of acceleration would decrease if the mass of the object increases.
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
F =m × a
As given in the problem, a net force of 60 N north acts on an object with a mass of 30 kg.
60 = 30 × acceleration
acceleration = 60 / 30
= 2 m / s²
Thus, the acceleration of the object would be 2 m / s² , and the acceleration would decrease if the mass of the object increases.
