Identify each unit as belonging to SI units or US Customary units.

Physics
1 answer:
torisob [31]3 years ago
6 0

Answer:

<em>SI Units</em>

              Meter

              Kilogram

              Kelvin

<em>US Customary Units and English Units</em>

              Gallon

              Mile

              Pound

              Degrees Fahrenheit

Explanation:

The SI units or International System of Units are the widely used metrics of measuring a physical quantity. It has specific abbreviations.

The US customary units is a measurement system where it is widely used in the united states. This system of unit also has abbreviations.

There are also conversion scales that are used to convert a unit from one metric system to the other.

For example, the conversion of mile to SI unit is given by the formula

                             1 mile = 1609.4 meters

Similarly,                

                             1 pound = 0.453592 Kg

Capacitances of 10uF and 20uF are connected in parallel,
jarptica [38.1K]

Answer:

The equivalent capacitance will be 15\mu F  

Explanation:

We have given two capacitance C_=10\mu F\ and\ C_2=20\mu F

They are connected in parallel

So equivalent capacitance C=C_1+C_2=10+20=30\mu F

This equivalent capacitance is now connected in series with 30\mu F

In series combination of capacitors the equivalent capacitance is given by \frac{1}{C}=\frac{1}{30}+\frac{1}{30}

C=\frac{30}{2}=15\mu F

So the equivalent capacitance will be 15\mu F

An electron is traveling at 0. 85c. what is its mass? (the rest mass is 9. 11 × 10-31 kg. )
egoroff_w [7]

The mass of the electron is 1.72\times 10^{-30} Kg.

<h3>How can we calculate the mass of the electron?</h3>

To calculate the mass of the electron we are using the formula,

m=\frac{m_{0} }{\sqrt{1-\frac{v^{2} }{c^{2} } } }

Here we are given,

m_0=The rest mass of an electron =  9. 11 \times 10^{-31} kg.

v= The velocity of electron =  0. 85c.

c= The velocity of light = c.  (c=3\times 10^8 m/s)

We have to found the mass of an electron = m Kg.

Now we substitute the known values, we found that,

m=\frac{9. 11 \times 10^{-31} }{\sqrt{1-\frac{(0.85c)^{2} }{c^{2} } } }

Or,m=\frac{9. 11 \times 10^{-31} }{\sqrt{1-(\frac{0.85c}{c})^2 } }

Or,m=\frac{9. 11 \times 10^{-31} }{\sqrt{1-({0.85})^2 } }

Or, m=1.72\times 10^{-30} Kg.

From the above calculation we can conclude that, The mass of the electron is 1.72\times 10^{-30} Kg.

the period of a mechanical wave is 12 seconds what is the frequency of the wave 12 waves/seconds 4.0 waves/seconds 0.083 waves/s
Mandarinka [93]

Use your units ! 
"Period" is time . . . 12 seconds.
"Frequency" how often . . . " ___ PER time".  Time is in the denominator.

"12 seconds per wave" means 

                                    1 wave / 12 seconds

                             =      (  1 / 12 )  (wave/second)

                             =            0.08333... wave per second

                             =            1/12  Hz.
