Which of the following best describes how a filter can be used to sort materials?
1. Filters allow objects that are less than a specific size to pass through, which lets you sort a mixture. This assumes that the sizes of each component are different and do not overlap.
2. Filters catch large objects, so filters can be used to sort out large components of mixtures.
3. Filters never help you sort mixtures because different components can all be the same or similar sizes.
4. Filters allow objects of a certain size to pass through, so if you know the size or size range of a certain component in a mixture, you can pass the entire mixture through a filter and sort out the component in that size range.

Imagine that you are a leaf on a plant, and you realize that you are running low on supplies to do your job. You decide to text the roots to set up a delivery. Write a text message conversation between the leaf and the roots that discusses and arranges this delivery.
Answers
Answer:
Leaf: Hey Roots, this is Leaf. I'm running low on supplies here. Can you send some over?
Roots: Hey Leaf, of course. What kind of supplies do you need?
Leaf: I need more water and nutrients. Can you send some my way?
Roots: Sure thing, we'll get on it right away. How much do you need?
Leaf: Just enough to keep me going for a few more days. Can you also send some sunlight my way?
Roots: Sorry, we can't help with that one. But we'll make sure to send enough water and nutrients to help you out.
Leaf: Thanks, Roots. You're the best. Let me know when the delivery is on its way.
Roots: Will do, Leaf. Hang in there. Delivery should be there soon.
Roots: Hi Leaf! Of course, we're here to help. Sorry to hear you're running low. We'll get right on it. How much water and which specific nutrients do you need?
Hope it helps! :)
Leaf: Thanks, Roots! I'll need a good soak of water, and I could use some extra nitrogen and potassium for optimal photosynthesis. Can you also throw in some magnesium?
Roots: Noted, Leaf. Water, nitrogen, potassium, and magnesium coming right up! We'll absorb them from the soil and deliver them through the xylem. Just hang in there!
Leaf: Awesome, Roots! Your support is much appreciated. Let's make sure this delivery boosts my chlorophyll production so I can keep producing energy for the whole plant.
Roots: Absolutely, Leaf! We're here to keep the whole plant thriving. Your health is our priority. We'll work together to ensure you have everything you need for top-notch photosynthesis.
Leaf: Thanks for being the best roots a leaf could ask for! Can't wait to feel rejuvenated and get back to making food for the plant.
Roots: You're welcome, Leaf! We're all part of the same team. Stay patient, the delivery will be on its way soon. We'll keep you updated.
Leaf: Will do, Roots! Looking forward to the delivery. Keep up the great work down there!
Roots: Thanks, Leaf! We'll keep the nutrients flowing. Take care up there and keep shining!
Leaf: You too, Roots! Catch you later!
Roots: Until next time, Leaf! Stay green and healthy!
7. What are convection currents in the mantle caused by?
A. The core heats up magma and increases its density, so it rises.
B. The core heats up magma and decreases its density, so it rises.
C. The core cools down magma and increases its density, so it rises.
D. The core cools down magma and decreases its density, so it rises
Answers
Answer: b
Explanation:
Heat from the core and the mantle itself causes convection currents in the mantle. It’s getting hotter. When something gets hotter, it is less dense.

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.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

Answers
Answer:
Equator and Arctic because equator is too hot and arctic is too cold. In equator the rays of the sun fall directly all over the year and this is why the [people living there experience a harsh hot weather and high temperatures. On the other hand people living in the Arctic region experience extreme cold because very little sunlight reaches there. Temperatures are freezing cold all over the year.
plz mark me as brainliest.
Answer:
The arctic does not suffer any seasons as it is furthest from the equator and therefore is covered in ice snow and rarely sees sunlight. Therefore the arctic does not have summer autumn or spring. The arctic is so cold that not many trees can survive and the ones that do are usually chopped down to build houses for the people who live there. The arctic is home to one of the worlds largest seed banks that is there in case of a really bad emergency where the farmers crops in another country are not growing.
