Answer:
Yes the statement is correct
Explanation:
The de-broglie relation is mathematically represented as
where
p is momentum of the system
From the relation we can see that the wavelength is inversely proportional to the momentum of the particle.
Answer:
0.0979 N/c
Explanation:
Electric field, E is given as a product of resistivity and current density
E=jP where P is resistivity and j is current density
But the current density is given as
where I is current and A is area and
Substituting this into the first equation then
Given diameter of 0.259 cm= 0.00259 m and the radius will be half of it which is 0.001295 m
Answer:
Both Vitamin D and folate level are affected by UV radiation from sunlight.
Explanation:
Answer:
i₃ > i₁ > i₂
Explanation:
For this exercise we use the resistance ratio
R = ρ
where ρ is the resistivity of the wire, in this case it is the same for all three cases, l the length and A the area of the wire.
We have three cases
a) length l = L
area A = A
b) length l = 2L
area A = A
c) length l = L
area A = 2A
we calculate the resistance for each case
a) R₁ = ρ L / A
b) R₂ = ρ 2L / A
R₂ = 2 ρ L / A
R₂ = 2 R₁
c) R₃ = ρ L / 2A
R₃ = ½ ρ L / A
R₃ = 0.5 R₁
therefore when the connect of the circuit is carried out we can use ohm's law
V = i R
i = V / R
whereby
a) i₁ = V / R₁
b) i₂ = V / 2R₁
i₂ = ½ i₁
i₂ = 0.5 i₁
c) i₃ = V / 0.5 R₁
i₃ = 2 I₁
the order from highest to lowest in the current is
i₃ > i₁ > i₂
Answer:
The force is inversely proportional to the square of radial distance and the mass of the lemon is compensated.
Explanation:
- It is true that our body is composed mostly of water (precisely 75% of the body mass) which is influenced by the gravitational forces. This gravitational force in the water bodies cause tides.
We know that mathematically gravitational force is given as:
where:
R = radial distance between the masses
we observe that:
The force is inversely proportional to the square of radial distance.
- And the radial distance between the moon and a human on the earth is much greater than the distance between a lemon of low mass on the head of a human.
