Answer:
1.776 x 10^-19 m
Explanation:
Energy, E = 7 TeV
Let λ be the wavelength.
Energy = h c / λ
Where, h is the Planks,s constant and c be the velocity of light
h = 6.63 x 10-^-34 Js
c = 3 x 10^8 m/s
Convert TeV into J
1 TeV = 1.6 x 10^-7 J
So, E = 7 x 1.6 x 10^-7 = 11.2 x 10^-7 J
11.2 x 10^-7 = (6.63 x 10^-34 x 3 x 10^8) / λ
λ = 1.776 x 10^-19 m
Explanation:
The problem doesn't specify that the units have to be g/mL, so you can calculate the density in kg/L without converting the mass or volume.
Just make sure that either way, you write the units.
Answer:
<h2>
The magnitude of the magnetic is 0.145 T</h2>
Explanation:
Given :
Speed of proton 
Mass of proton
Kg
The force on the proton in magnetic field is given by,

But
(∵ Force is perpendicular to the velocity so
)

When particle enter in magnetic field at the angle of 90° so particle moves in circle
So force is given by,

Where
radius but in our case 0.23 m,
C
By comparing above two equation,


T
Answer:
The diameter is 0.000056 m
Explanation:
Lets explain the relation between the meter and the micrometer
1 Meter is equal to 1000000 (one million) micrometers
1 micrometer = 
The symbol of the meter is m
The symbol of micrometer is μm
A human hair is approximately 56 µm in diameter
We need to express this diameter in meter
To do that we divide this number by 1,000,000 or multiply it by 
→
56 µm = 0.000056 m
→ OR
→
→ 56 µm = 0.000056 m
<em>The diameter is 0.000056 m</em>
Gravitational potential energy = mgh or mass times acceleration due to gravity times the height
Here the mass is 0.25kg, the height is 10m, and gravity is 9.8m/s^2 so...
GPE = (0.25)(10)(9.8)
GPE = 24.5 J
