Answer:

E kin = 1/2 • m • v^2

E kin: kinetic energy

m: mass

v: velocity

What current flows through a 2.62 cm diameter rod of pure silicon that is 23.5 cm long, when 1000 v is applied to it? (such a ro
arlik [135]
Resistivity = resistance * Area / Length
resistance = ??
rho = 2.30 * 10^3 ohms meters.
l = 23.5 cm = 0.235 meters.
diameter = 2.62 cm = 0.0262 m
Radius = diameter / 2 = 0.0131 m
Area = pi r^2 where pi = 3.14
Area = 3.14 * 0.0131^2 = 0.000539 m^2

2.30 * 10^3 = R * 0.000539 /0.235
2.30 * 10^3 * 0.235/0.000539 = R
R = 1002783 which is about 1 meg ohm, but I'll use the calculation here.

E = 1000 V
R = 1 002 783 ohms
I = ???

E = I * R
1000 = I * 1002783 We should really round that resistor to 1 megohm or 1 * 10^6 ohms.

I = 1*10^3 / 1 * 10^6
I = 1 * 10^-3 amp = 1 milliamp. Pretty reasonable all things considered.

"how long would it take for a ball dropped from the top of a 400-foot building to hit the ground? round your answer to two decim
Lelechka [254]
Hello

Let's convert first the height from foot to meters:
S=400~ft=121.92~m
This is the space covered by the ball in its accelerated motion, where the acceleration is the gravitational acceleration:
a=g=9.81~m/s^2
The law of motion is given by
S= \frac{1}{2}at^2
Re-arranging, we can get the total time of the motion:
t= \sqrt{ \frac{2S}{a} }=4.99~s

which is the time the ball takes to hit the ground.

A truck and a scooter moving with the same velocity colide. Why does the scooter fly off?
iragen [17]
We know, Momentum is the product of mass and velocity. As velocity is equal, momentum of Truck will be greater as mass of Truck is greater than the scooter. As momentum is greater from truck side, it will transfer the same amount to the scooter, so it flies away

Hope this helps!

Two waves of equal magnitude but opposite phase interfere with one another to cause the waves to disappear. This is caused by:
nexus9112 [7]
<span>Destructive Interference. This gives the effect of making the two waves disappear at the moment they meet. After the 2 waves cancel each other at the monent when they overlap, the waves continue in the same direction and magnitude as they were originally.</span>
