determine the velocity of a cart traveling at 135cm in 5.5s.

Answers

velocity = distance/time

distance = 135cm
time = 5.5 s

velocity = 135 cm/5.5 s
velocity = 24.546 cm/s

Answer: 0.245 m/s

Explanation:

So velocity = d/t or distance over time in this case m/s or meters per second. But BE CAREFUL you must remember to convert cm to m always so 135 cm= 1.35m and 1.35m/5.5s= 0.245m/s

You take a gas at 3 atm and increase the temperature from 120 K to 240 K. What is the final pressure?
A
6 atm
B
Not enough information
C
3 atm
D
1.5 atm

Answers

Answer:

A. 6atm

Explanation:

Using pressure law equation:

P1/T1 = P2/T2

Where;

P1 = initial pressure (atm)

T1 = initial temperature (K)

P2 = final pressure (atm)

T2 = final temperature (K)

According to this question;

P1 = 3 atm

P2 = ?

T1 = 120K

T2 = 240K

Using P1/T1 = P2/T2

3/120 = P2/240

Cross multiply

240 × 3 = P2 × 120

720 = 120P2

P2 = 720/120

P2 = 6atm

Gas in a balloon occupies 3.3 liters. What volume will it occupy if the pressure is changed from 100 kPa to 90.0 kPa, if the temperature is held constant?

Answers

Answer:

3.7 L

Explanation:

Initial volume (V₁) = 3.3 L

Initial pressure (P₁) = 100 KPa

Final pressure (P₂) = 90 KPa

Final volume (V₂) =?

The final volume of the gas can be obtained by using the Boyle's law equation as follow:

P₁V₁ = P₂V₂

100 × 3.3 = 90 × V₂

330 = 90 × V₂

Divide both side by 90

V₂ = 330 / 90

V₂ = 3.7 L

Thus, the final volume of the gas is 3.7 L

Answers

Answer:

we find the mass for each element in one mole by multiplying the number of atoms in one molecule with the atomic mass

mC=8Ac=8*12=96g

mH=10AH=10*1=10g

mN=4AN=4*14=56g

mO=2AO=2*16=32g

by adding the masses together we find the molar mass of the molecule

M=mC+nH+mN+mO=96+10+56+32=194g/mole

we apply the rule of threes to find the percentage of each element

194g..96gC..10gH...56gN....32gO

100g....a...........b...........c.............d

a=(100*96)/194=49.48%C

b=(100*10)/194=5.19%H

c=(100*56)/194=28.85%N

What are resistors? please help​

Answers

Answer:Resistor Basics

Resistors are electronic components which have a specific, never-changing electrical resistance. The resistor's resistance limits the flow of electrons through a circuit.

They are passive components, meaning they only consume power (and can't generate it). Resistors are usually added to circuits where they complement active components like op-amps, microcontrollers, and other integrated circuits. Commonly resistors are used to limit current, divide voltages, and pull-up I/O lines.

Resistor units

The electrical resistance of a resistor is measured in ohms. The symbol for an ohm is the greek capital-omega: Ω. The (somewhat roundabout) definition of 1Ω is the resistance between two points where 1 volt (1V) of applied potential energy will push 1 ampere (1A) of current.

As SI units go, larger or smaller values of ohms can be matched with a prefix like kilo-, mega-, or giga-, to make large values easier to read. It's very common to see resistors in the kilohm (kΩ) and megaohm (MΩ) range (much less common to see miliohm (mΩ) resistors). For example, a 4,700Ω resistor is equivalent to a 4.7kΩ resistor, and a 5,600,000Ω resistor can be written as 5,600kΩ or (more commonly as) 5.6MΩ.

Schematic symbol

All resistors have two terminals, one connection on each end of the resistor. When modeled on a schematic, a resistor will show up as one of these two symbols:

Resistor schematic symbols

Two common resistor schematic symbols. R1 is an American-style 1kΩ resistor, and R2 is an international-style 47kΩ resistor.

The terminals of the resistor are each of the lines extending from the squiggle (or rectangle). Those are what connect to the rest of the circuit.

The resistor circuit symbols are usually enhanced with both a resistance value and a name. The value, displayed in ohms, is obviously critical for both evaluating and actually constructing the circuit. The name of the resistor is usually an R preceding a number. Each resistor in a circuit should have a unique name/number. For example, here's a few resistors in action on a 555 timer circuit:

Answer: resistor is

Explanation:

A resistor controls the flow of the electrical current within a circuit. Resistors are made from materials like copper or carbon, which make it difficult for the electrical charges to flow through a circuit. The most common type of resistor is a carbon resistor, which is a general purpose resistor, best suited for lower-powered circuits.
