Explanation:
Trees, because of their height, are natural lightning rods. Electricity seeks the path of least resistance, and the moisture inside a tree is a much better conductor than air. This means a tree provides the preferred path for lightning to reach the ground.
Explanation:
a block of iron in denser then the block of wood
as the atoms in iron are more closely bounded as compared to that in the wood
if both are drop in water iron block sink to bottom while float on the level
Answer:
conserving water is important because it keeps water pure and clean while protecting the inviorment
Answer:
the interaction in the protein is greater than the surface with water
\frac{F_i}{F_s} = \frac{\epsilon_s}{ \epsilon_i} \ > 1
Explanation:
The electric force for a charge is
F =
In the exercise indicate that the charge is q and the distance r is maintained, the test charge is another
therefore if we use the index i for the dielectric constant () in the protein
the electric force in water with dielectric constant ()
if we look for the relationship between these forces
therefore the interaction in the protein is greater than the surface with water
Answer:
The magnetic flux through the loop is 0.006284 m².T
Explanation:
Given;
radius of circular loop, r = 0.1 m
magnetic field strength, B = 0.2 T
Magnetic flux through the loop due to the external field is given as;
Φ = BAcosθ
where;
Φ is magnetic flux
B is the magnetic field strength
A is the area of the loop
θ is the angle of inclination of between the plane of the loop and external magnetic field
A = πr² = π(0.1)² = 0.03142 m²
θ = 0, since they are parallel
Φ = BAcosθ
Φ = 0.2 x 0.03142 x cos0
Φ = 0.006284 m².T
