You should ALWAYS wear lab coats and safety goggles because if anything gets in your eye that will be bad.You should always wear sneakers.If any chemical falls on your open toes then that can hurt you and effect you in a lot of ways.Some labs have this rule,you are not aloud to eat or drink in lab.Hope this helps!

A typical current in a lightning bolt is 103 a. estimate the magnetic field 9 m from the bolt (in t). (enter the magnitude.)

kifflom [539]

The magnetic field is

$2.288 \times 10 {}^{ - 6} T$

what is magnetic field?

Magnetic field is defined as the relationship between the permittivity of free space,the magnitude of electric current,and distance.

Here is the formula,

$B = \frac{µ0l }{2π R}$

here,

B= magnitude of the magnetic field

l= magnitude of electric current

R=distance

µ0=permittivity of free space

Now,using above formula we can calculate the magnetic field

$B = \frac{µ0l }{2π R}$

$\frac{4\pi \times 10 {}^{ - 7}. \frac{m}{a} \times 103 }{2\pi \times (9m)}$

$= 2.288 \times 10 {}^{ - 6} T$

Thus,the magnetic field is

$= 2.288 \times 10 {}^{ - 6} T$

The time between a lightning flash and the following thunderclap may be used to estimate, in kilometers, how far away a storm is

Kruka [31]

Given Information:

Elapsed time = t = 6 seconds

Required Information:

Distance = d = ?

Answer:

Distance = d = 2.058 km

Explanation:

We know that the speed of sound in the air is given by

v = 343 m/s

The relation between distance, speed and time is given by

distance = speed*time

substituting the given values yields,

distance = 343*6

distance = 2058 m

There are 1000 meters in 1 km so

d = 2058/1000

d = 2.058 km

Therefore, the storm is about 2.058 km away when elapse time between the lightning and the thunderclap is 6 seconds.
