The small particles that produce a streak of light upon entering earth’s atmosphere are called

Answers

They are called meteors... i just took the test

Explanation:

When a meteoroid enters the earth's atmosphere at high speed, a streak of light called meteor is observed. This light effect is produced by the ionization of air molecules in the upper atmosphere (at altitudes from 76 to 100 km). Most of these are the size of a grain of sand.

at a pressure 44 kpa the gas in a cylinder has a volume of 29 liters assuming temperature remains the same,if the volume of the gas is decreased to 4liters what is the new pressure?kpa

Answers

Assuming the gas is ideal, the ideal gas law can be used. To make things simpler, Boyle's law can also be used because it denotes the inverse relationship between pressure and volume at constant temperature. The solution to be used is as follows

P1V1 = P2V2
(44)(29) = P2(4)
P2 = 319 KPa

A flashlight has a resistance of 2.4 what voltage is applied by the batteries if the current in the circuit is 2.5 a?

Answers

Explanation :

The resistance of the flashlight is 2.4 ohms

The current flowing in the circuit is 2.5 A

The Ohm's law gives the relation between the following quantities i.e.

Current

voltage

and resistance

Mathematically, Ohm's law can be written as :

V =I R

V=2.5\ A* 2.4\ \Omega

V=6\ Volts

The voltage applied by the batteries is 6 volts.

Hence, this is the required solution.

During a laboratory experiment, a student findsthat at 20° Celsius, a 6.0-meter length of copper
wire has a resistance of 1.3 ohms. The crosssectional
area of this wire is
(1) 7.9 × 10^−8 m2 (3) 4.6 × 10^0 m2
(2) 1.1 × 10^−7 m2 (4) 1.3 × 10^7 m2

Answers

The cross-sectional area of the copper wire is which has 1.3 ohm at 20 degree Celsius during laboratory experiment by student is 7.9×10⁻⁸ ohm.

What is the resistance?

Resistance is obstacle for the current flow in the circuit. It is the measure of reverse act to current flow in through a material. It can be given as,

R=\rho(L)/(A)

Here, (ρ) is the specific resistance (l) is the length of the wire and (A) is the cross-sectional area of the wire.

During a laboratory experiment, the student finds that at 20° Celsius, a 6.0-meter length of copper wire has a resistance of 1.3 ohms.

The value of resistivity of copper wire is 1.72×10⁻⁸ ohm-m. Put these values in the above formula as,

R=\rho(L)/(A)\n1.3=1.72*10^(-8)*(6)/(A)\nA=7.9*10^(-8)\rm \; m^2

Thus, the cross-sectional area of the copper wire is which has 1.3 ohm at 20 degree Celsius during laboratory experiment by student is 7.9×10⁻⁸ ohm.

ρ = resistivity of copper at 20 °C = 1.72 x 10⁻⁸ ohm-m

R = resistance of the copper wire = 1.3 ohm

L = length of the copper wire = 6 meter

A = area of cross-section of the copper wire = ?

Resistivity of copper wire is given as

R = ρL/A

inserting the values in the above equation

1.3 = (1.72 x 10⁻⁸) (6)/A

A = 7.9 x 10⁻⁸ m²

Hence the correct choice is

(1) 7.9 x 10⁻⁸ m²

A a0 is the amount of heat needed to raise the temperature of one kilogram of water one degree centigrade.

Answers

The correct answer that would best complete the given statement above would be the term KILOCALORIE. A KILOCALORIE  is the amount of heat needed to raise the temperature of one kilogram of water one degree centigrade. On the other hand, the amount of heat needed to raise the temperature of one gram of water one Centigrade degree is calorie. Hope this answer helps.

I got this correct on Odyssey-ware the answer is Kilocalorie
