Answer:
yes
Explanation:
He used the formula R = VI and obtained an
answer of 2
because water is loosely packed but when it is cold it becomes closely packed in order to form ice and thus the force attraction between them also increase.
Answer:
Explanation:
When the screw is turned by two turns then change in the length of the wire is given as
now we know by the formula of Young's modulus
so we have
Answer:
ΔE> E_minimo
We see that the field difference between these two flowers is greater than the minimum field, so the bee knows if it has been recently visited, so the answer is if it can detect the difference
Explanation:
For this exercise let's use the electric field expression
E = k q / r²
where k is the Coulomb constant that is equal to 9 109 N m² /C², q the charge and r the distance to the point of interest positive test charge, in this case the distance to the bee
let's calculate the field for each charge
Q = 24 pC = 24 10⁻¹² C
E₁ = 9 10⁹ 24 10⁻¹² / 0.20²
E₁ = 5.4 N / C
Q = 32 pC = 32 10⁻¹² C
E₂ = 9 10⁹ 32 10⁻¹² / 0.2²
E₂ = 7.2 N / C
let's find the difference between these two fields
ΔE = E₂ -E₁
ΔE = 7.2 - 5.4
ΔE = 1.8 N / C
the minimum detection field is
E_minimum = 0.77 N / C
ΔE> E_minimo
We see that the field difference between these two flowers is greater than the minimum field, so the bee knows if it has been recently visited, so the answer is if it can detect the difference
Answer:
Meteorites have comparatively huge size than the size of the meteors
The meteorites are originated as the debris from an a comet, asteroid, or meteoroid due to a heavy impact. Whereas, the meteors are the dust formed from an asteroids.
Explanation:
The difference between the meteorites from the meteors is that, the meteorites have comparatively huge size than the size of the meteors. Also, the meteorites are capable enough to survive moving through the earth's atmosphere. while the meteors burns up due to heat produced by the friction while moving in the earth's atmosphere.
The meteorites are originated as the debris from an a comet, asteroid, or meteoroid due to a heavy impact. Whereas, the meteors are the dust formed from an asteroids.
