Anyone know how to do this

Physics

The answer to your question is:  Yes.  

To solve each and every one, write the two given numbers in place of their letters in the given equation, and then solve the equation for the letter that's left.

For example, let's do #1 together.  I'll do all the work, and you just watch.

#1 says that s=d/t.  It also tells us that 'd' is 4 and 't' is 2.  So here's a great idea:  Why don't we write '4' where it says 'd', and write '2' where it says 't', and then see what we've got ?

s = 4/2

Wow !  We know that 4/2 is 2 .  So s=2 and that's exactly the answer to the question !

Now it's YOUR turn.  Do the next 25 problems the same way.

Wire sizes are often reported using the AWG (American Wire Gauge) system in which smaller diameter wires are said to be of highe
NISA [10]

Answer:

Explanation:

24 - gauge wire , diameter = .51 mm .

Resistivity of copper ρ = 1.72 x 10⁻⁸ ohm-m

R = ρ l / s

1.72x 10⁻⁸ / [3.14 x( .51/2)² x 10⁻⁶ ]

= 8.42 x 10⁻² ohm

= .084 ohm

B )  Current required through this wire

= 12 / .084 A

= 142.85 A

C )

Let required length be l

resistance = .084 l

2 = 12 / .084 l

l = 12 / (2 x .084)

= 71.42 m

A wave has a velocity of 24 m/s and a period of 3.0 s. Calculate the wavelength of the wave.
Katyanochek1 [597]

Velocity (unit:m/s) of the wave is given with the formula:

v=f∧,

where f is the frequency which tells us how many waves are passing a point per second (unit: Hz) and ∧ is the wavelength, which tells us the length of those waves in metres (unit:m)

f=1/T , where T is the period of the wave.

In our case: f=1/3

∧=v/f=24m/s/1/3=24*3=72m
