Answer:
1. troposphere
2. troposphere (still)
3. The most abundant gas in the atmosphere is nitrogen, with oxygen second. Argon, an inert gas, is the third most abundant gas in the atmosphere.
4.The stratosphere is where you'll find the very important ozone layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection.
5. It contains the ozone, which protects Earth from the sun's radiation. Why aren't there many meteors in the troposphere? They burn up before they reach the troposphere.
Explanation:
1.The troposphere is the atmospheric layer closest to the planet and contains the largest percentage (around 80%) of the mass of the total atmosphere. Temperature and water vapor content in the troposphere decrease rapidly with altitude.
2.The layer closest to Earth's surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface. The troposphere is thickest at the equator, and much thinner at the North and South Poles.

magnets' persistent magnetic fields.Things that create their own persistent magnetic fields are known as permanent magnets.They have a north and a south pole and are built of magnetized ferromagnetic elements, such as iron and nickel.
More than one solution to the question "what causes a magnetic field?"
may be true.Charged particles that are in motion produce all magnetic fields.Due to the continually moving electrons inside, even the magnet on your refrigerator is magnetic. A magnetic field is produced along the axis of a wire loop by a current flowing through it.Curling the fingers of the right hand in the direction of the current through the loop and pointing the thumb in the direction of the magnetic field will reveal the direction of the field inside the loop. The magnetic field strength of an electromagnet or solenoid, depends on the number (N) of coil turns, the strength of current flowing through the coil in amperes, and its length L. This gives us: H = (NI)/L where NI represents the ampere-turns value.Items made of iron, cobalt, nickel, and steel are drawn to magnets.Paperclips are magnetic because they are often constructed of galvanized steel wire. Any of the following techniques can create a magnetic field:I Any type of magnet, including round, horseshoe, and bar magnets, may be employed.(ii) A current-carrying wire generates a field all around it.(iii) A current-carrying loop or solenoid Electric charges in motion are what generate magnetism.The smallest building blocks of matter are called atoms.There are electrons in every atom, which are charged particles.The electrons that make up an atom's nucleus, or core, spin like tops. Ampere noted that whenever an electrical charge is moving, a magnetic field is created.Similar to how an electrical current flowing through a wire creates a magnetic field, the spinning and circling of an atom's nucleus accomplishes the same.The magnetic field's orientation is determined by the spin and orbit directions. There are only two ways to create a powerful magnetic field.In the first, a solenoid is used, whereas in the second, a solenoid with an iron core is used. Magnetic materials found in nature are connected to magnetic fields.Instead of static charges, a magnetic field can be produced by moving charges.F = QVB, where Q is the charge and V is the charge's velocity perpendicular to the field B, describes the force acting on moving charges in a magnetic field.To learn more about magnetic field refer

difference in potential between these two points?
Answers
Answer: 5V
Explanation: because 2 goes into 10, five times. Also I know it’s correct cuz I got it right in my quiz
The difference in potential between these two points is 5 V.
Electric potential between the two points
The electric potential between two points is the work done in taking a unit postive charge from one point to another.
The difference in potential between these two points is calculated as follows;
W = qV
V = W/q
V = 10/2
V = 5 V
Thus, the difference in potential between these two points is 5 V.

2) (b) the length of the wire being tested
Explanation:
1) An ammeter is connected in series with the circuit branch in which you want to measure current. "Conventional current" enters the positive terminal of the ammeter. (You can think of it as a voltmeter across a small resistor. The polarity of the voltage matches the polarity of the current.)
A voltmeter is connected in parallel with the circuit element of interest. Here, you want to measure the voltage across the wire, so the voltmeter is placed in parallel with the wire. The positive terminal of the voltmeter is connected to the end of the circuit element that has the higher (more positive) potential.

2) The wording of the problem tells you which variable is independent:
"A varies with B" means the independent variable is B
Here, the independent variable is the length of the wire.

If the specific heat of iron = 0.46J C, how much heat is needed to warm 50 g of iron from 20C to 100C
Answers
Answer:
1840 J
Explanation:
From the question given above, the following data were obtained:
Specific heat capacity (C) = 0.46 J/gºC
Mass (M) = 50 g
Initial temperature (T₁) = 20 °C
Final temperature (T₂) = 100 °C
Heat (Q) required =?
Next, we shall determine the change in the temperature. This can be obtained as follow:
Initial temperature (T₁) = 20 °C
Final temperature (T₂) = 100 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 100 – 20
ΔT = 80 °C
Finally, we shall determine the heat required. This can be obtained as follow:
Specific heat capacity (C) = 0.46 J/gºC
Mass (M) = 50 g
Change in temperature (ΔT) = 80 °C
Heat (Q) required =?
Q = MCΔT
Q = 50 × 0.46 × 80
Q = 1840 J
Thus, 1840 J of heat energy is required.

If a chemical reaction has a AH value of -125 kJ, it would be considered what?
Answers
Answer:
Exothermic Reaction
Explanation:
ENDOTHERMIC REACTION: A chemical reaction is considered endothermic if the energy is absorbed during the reaction. In other words, if the energy is required by the reactants to proceed with the reaction, then the reaction is endothermic.
The value of enthalpy change ΔH is positive in such reactions showing intake of energy.
EXOTHERMIC REACTION: A chemical reaction is considered exothermic if the energy is released during the reaction. In other words, if the energy is produced as a product of the reaction, then the reaction is exothermic.
The value of enthalpy change ΔH is negative in such reactions showing the release of energy.
Since, the value of ΔH = -125 KJ, is negative for the given reaction.
Therefore, it would be considered as Exothermic Reaction.

A truck skids for a distance of 25m with the road pushing on its tires with force of 1500N as its brakes are applied. What is the change in kinetic energy for the truck?
Answers
Answer:
37500 J
Explanation:
Law of conservation of energy: Its states that energy can neither be created nor destroyed but it can be transformed from one form to another.
Applying the law of conservation of energy.
The change in kinetic energy for the truck = Net work done by the truck skids
ΔK.E = F×d.................... Equation 1
Where ΔK.E = Change in kinetic energy, F = Force, d = distant.
Given: F = 1500 N, d = 25 m
Substitute these values into equation 1
ΔK.E = 1500×25
ΔK.E = 37500 J

A 1,100 kg car is going at 22 m/s. Force is needed to stop it in 20
seconds is 1210 N.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Using equation of motion,
v = u + at
0 = 22 + a.20
a = 1.1 m/sec²
force = mass.acceleration
force = 1100.(1.1)
force = 1210 N.
