The force that is acted on the box causes the box to move and i this case isabela is able to move the box.
Answer:
Explanation:
Let the magnitude of magnetic field be B .
flux passing through the coil's = area of coil x field x no of turns
Φ = 3.13 x 10⁻⁴ x B x 135 = 422.55 x 10⁻⁴ B .
emf induced = dΦ / dt , Φ is magnetic flux.
current i = dΦ /dt x 1/R
charge through the coil = ∫ i dt
= ∫ dΦ /dt x 1/R dt
= 1 / R ∫ dΦ
= Φ / R
Total resistance R = 61.1 + 44.4 = 105.5 ohm .
3.44 x 10⁻⁵ = 422.55 x 10⁻⁴ B / 105.5
B = 3.44 x 10⁻⁵ x 105.5 / 422.55 x 10⁻⁴
= .86 x 10⁻¹
= .086 T .
Answer: approximately 0.0556atoms of 14C
Explanation:
Since 1000atoms of 14C was presently found in the atom that was created 18000years ago. The number of atoms of 14C that will be in that object when it was made will be 1000/18000 which is 0.0556atoms of 14C.
Note that the number of atoms present in it 18000years ago will be a way smaller than present atoms of 14C in it
The answer is Activation Energy …………….
To oscillate is to move or swing back and forth at a regular speed.
An oscillating telephone pole is similar to an oscillating tuning fork because they are both swinging back and forth, but the tuning forth is most likely oscillating at a much higher speed.
