Answer:
The magnetic flux through surface is
Wb
Explanation:
Given :
Magnitude of magnetic field
T
Radius of circle
m
Angle between field and surface normal
25°
From the formula of flux,


Where
angle between magnetic field line and surface normal,
area of circular surface.



Magnetic flux is given by,

Wb
Therefore, the magnetic flux through surface is
Wb
Explanation:
Osteopetrosis is a condition in which bones become weak and brittle. It causes the body to constantly absorb and replace bone tissue. With osteoporosis, new bone creation doesn't keep up with old bone removal.
While some don't experience symptoms, common symptoms can include bone fracture and a decrease in height.
Most treatments include supplements and diet modifications.
Answer:
Frequency, 
Explanation:
Given that,
The wavelength of the x-rays, 
We need to find the frequency of an x-ray. All electromagnetic wave travel with a speed of light. It is given by the formula as :

f is the frequency

So, the frequency of an x-ray is
. Hence, this is the required solution.
<u>Answer</u>
46,200 J
The energy of given out when a substance is losing heat is given by:
H = mcΔθ
Where m is the mass of the substance,
c is the specific heat capacity of the substance and
Δθ is the temperature change.
H = 0.50 × 22 4200
= 46,200 Joules.
We know that speed equals distance between time. Therefore to find the distance we have that d = V * t. Substituting the values d = (72 Km / h) * (1h / 3600s) * (4.0 s) = 0.08Km.Therefore during this inattentive period traveled a distance of 0.08Km
