Marina CMI [18]

The principle that describes the force on a charge in a magnetic field was named for Hendrik Lorentz, and the principle is named as Lorentz force.

Hendrik Antoon Lorentz (18 July 1853 – 4 February 1928) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect.

Grain is pouring into a silo to be stored for later use. Due to the friction between pieces of grain as they rub against each ot

jolli1 [7]

Answer:

The electric force between them if the pieces of grain are 2 cm apart is $3.15\times 10^{-11}\textrm{ N}$ .

Explanation:

Given:

Charge on one grain, $Q_{1}=6\times 10^{-10}\textrm{ C}$

Charge on another grain, $Q_{2}=2.3\times 10^{-15}\textrm{ C}$

Separation between them, $d=2\textrm{ cm}=0.02\textrm{ m}$

Electric force acting between two charges $Q_{1}\textrm{ and }Q_{2}$ separated by a distance $d$ is given as:

$F_{elec}=\frac{kQ_{1}Q_{2}}{d^2}$

Where, $k$ is Coulomb's constant equal to $9\times 10^9\textrm{ }Nm^2/C^2$ .

Now, plug in all the values and solve for $F{elec}$ .

$F{elec}=\frac{9\times 10^9\times 6.0\times 10^{-10}\times 2.3\times 10^{-15}}{(0.02)^2}\\\\F_{elec}=3.15\times 10^{-11}\textrm{ N}$

Therefore, the electric force between them if the pieces of grain are 2 cm apart is $3.15\times 10^{-11}\textrm{ N}$ .

Answer:

Question not completed, so I analysed the question first

Tony drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 6 hours. when tony drove home, there was no traffic and the trip only took 4 hours. if his average rate was 22 miles per hour faster on the trip home, how far away does tony live from the mountains?

Explanation:

Let use variables to solve the problems

Let the first trip to be mountain take x hours

Let the trip back home take y hours

Let the speed to while going to the mountain be a miles/hour

Then, while going home it was b miles/hour faster than while going to the mountain.

Then, speed going home is (a+b)miles / hour

The formula for speed is given as

Speed=distance/time

The constant through out the journey is distance, the two journey has the same distance.

Then,

Distance =speed×time

For first journey going to the mountain

Distance = a×x=ax miles

For the second journey going home

Distance =y×(a+b)

Distance Mountain= distance home

ax=y(a+b)

Make a subject of the formula

ax=ya+yb

ax-ya=yb

a(x-y)=yb

a=yb/(x-y)

Therefore, distance from mountain is

Distance=speed ×time

Distance= a×x=ax

Now, applying the questions

So from the questions

x=6hours, y=4hours

Also, b=22miles/hour

Then,

a=yb/(x-y)

a=4×22/(6-4)

a=88/2

a=44miles/hour

Then, the house distance from the mountain is

Distance=ax

Distance =44×6

Distance =264miles
