Radiation is said to be process where heat is transferred between two objects in the form of electromagnetic waves . In radiation two object dont need to be in direct physical contact for the heat transfer to happen .
How is density different from weight and mass?
Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.

How would you connect these items to make a circuit in order to power a light bulb? step by step explanation
-a light bulb
-2 batteries
-aluminum foil
-paper clips
-electric tape
Answer:
How would you connect these items to make a circuit in order to power a light bulb? step by step explanation
Making a Circuit:
1. Connect one end of each wire to the screws on the base of the light bulb holder. (If you’re using foil, ask an adult to help you unscrew each screw enough to fit a foil strip under it.)
2. Connect the free end of one wire to the negative (“-“) end of one battery. Does anything happen?
3. Attach the free end of the other wire to the positive (“+”) end of the battery. Now what happens?
Adding Power :
1. Disconnect the battery from your circuit. Stand one battery so that the “+” end is pointing up, then set the other battery next to it so that the flat “-” the end is pointing up. Tape around the middle of the batteries to hold them together.
2. Set a paperclip across the batteries so that it connects the “+” end of one to the “-” end of the other. Tape the paperclip in place with a narrow piece of tape (do not tape over the metal battery ends).
3. Turn the batteries over and tape one end of a paper clip onto each of the batteries. Now you can connect one wire to each paper clip. (The bottom of the battery pack should only have one paper clip – do not connect a wire to it.)
4. Connect the free ends of the wires to the light bulb.
(Note: Instead of steps 1-3, you can use two batteries in battery holders and connect them together with one wire.)

What is one way that potential energy might be involved in rescue team missions?
Answer: The rescue workers can get energy to the batteries in their equipment during rescue missions by using a generator to convert the kinetic energy to potential energy. Potential energy is then stored in the battery.
Explanation:
From a quizlet i found online.
Answer:by using a generator to convert the kinetic energy to potential energy. Potential energy is then stored in the battery
What is an ellipse please help)
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
Maybe they might use that math thing for Science.
What physical property of mercury makes it best suited for use in a thermometer
Answer:
High coefficient of expansion
Explanation:
It is only mercury that is in liquid form at room temperature. It works on the principle of thermal expansion, it expands when heated and contracts when cooled. The very minute change can be notable by the use of mercury in the thermometer. So this property of the thermometer makes it suitable for measuring temperatures.
Why is it necessary to ensure that unreacted chlorine gas is passed into a fume cupboard when reacting with alumnium?
please helpppppppp.will give 12 points
Answer:
Heat
Explanation:
When energy transfers, due to the difference in temperatures, the energy that is passed on from a surface to another surface is heat. Therefore, we get heat transfer. Heat transfers happen in 3 ways radiation, convection, and conduction.

List the five physical phase changes of matter and give one example for each.
Answer:Melting.
Freezing.
Evaporation.
Condensation.
Sublimation.
Explanation:
Answer: Examples for the five transformations previously given.
For the first four, we encounter common examples in everyday life, all to do with water:
Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.
Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.
Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.
Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer
While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.
Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.

Which of the following solute(s) would form an electrolytic solution in water? CH4, KI, fecl3
Answer:
kl
Explanation:
According to the concept of solubility and electrolysis , KI would form an electrolytic solution in water.
What is solubility?Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
If you are leading a team to clean an oil spill in rough waters, which of the following methods would be most effective to clean the oil?
Install booms made from, or with, sorbent materials around the oil spill.
Install hard booms around the oil spill.
Coat the surface of the water with a sorbent material.
Wait until the water calms down and then install booms to contain the spill.
Answer:Install booms made from, or with, sorbent materials around the oil spill.
Explanation:Dispersants and booms and skimmers are the most frequently used methods to clean up ocean oil spills. All methods have advantages and disadvantages. The effectiveness depends on the situation – the amount and type of oil, the ocean currents and tides and the weather.

Answer:
-- I can't be too sure, but... --
Relative dating
Explanation:
Determination of the absolute age of rocks and minerals using certain radioactive isotopes.
Relative Age: The age of a rock layer compared to other layers. It can be determined by looking at the position of the rock layers.
Relative Dating: Rocks and structures are placed in order from the age of older to younger.
These two seem to be from the same section and they connect as well, so I believe "Relative Dating" is your answer but I could be wrong nevertheless I hope this helps you!
