Final velocity=2m/s
kinetic energy lost = 96J
Explanation:
This question is an example for total inelastic collision.
For this type of collision, the equation is,
Step1: Finding the velocity
m1v1+m2v2 =(m1+m2) vf
4*8+12*0 = (4+12)v
32 = 16v
= 2m/s
Step 2:Finding the kinetic energy
Kinetic Energy before collision=
Kinetic Energy before collision= 128J
Kinetic Energy after collison= 32J
Step 3: Finding the kinetic energy lost
Kinetic Energy lost = Kinetic Energy after collision – Kinetic Energy before collision
Kinetic energy lost=128 -32
Kinetic energy lost=96J
Answer:
The mass of the 500 series bullet train is 181.4 tonnes.
Explanation:
The momentum is given by:
Where:
m: is the mass =?
v: is the velocity = 261.8 km/h
p: is the momentum = 13194098.64 kg*m/s
By solving the above equation for "m" we have:
Therefore, the mass of the 500 series bullet train is 181.4 tonnes.
I hope it helps you!
<span>Beam Light wavelength = 506 nanometer
Frequency of light = F
The color of light = L
To fine the electromagnetic field:
=> S = wavelength x Frequency
Frequency = (3 x 10^8) / (5.06 x 10^ -7)
F = 5.96 x 10^14 Hz
According to the visible light spectrum, wavelength from 495 to 570 is equals
to the color of green. Since the given wavelength is 506, thus, the color of
light is green.
F = 5.96 x 10^14 Hz
L = green</span>
A compass will always point north when placed on a flat surface.
What is the variable?
~<em>the</em><em> </em><em>price</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>variable</em><em>.</em>
What happens to demand?
~It'll go down. Since the price of snow blowers will increase then the quantity demanded will go down.
Hope this helps- have a good day bro cya)
