Answer:
Allison is probably looking at the asteroid.
Explanation:
- Asteroids are the giant gas balls of inner solar system that are present in the space.
- Asteroids orbits around the sun in very irregular ans strange path unlike the other planets.
- This is also the reason why it's called as the minor planets.
- It could have been comet but if it had been a comets he must have seen the tail but asteroids do not have any tail like structure.
Answer:
Explanation:
This is case of interference in thin films
for constructive interference in thin film the condition is
2μ t = (2n+1)λ/2 ; μ is refractive index of oil , t is thickness of oil , λ is wave length of light .
2 x 1.28 x t = λ/2 , if n = 0
2 x 1.28 x t = 605 /2
t = 118.16 nm .
the minimum non-zero thickness of the oil film required = 118.16 nm.
Wind or gravitational pull. A wave is made by friction between wind and the water’s surface. Waves can also be made by the sun and moon’s gravitational pull on the earth.
To solve this problem it is necessary to apply the concepts related to the Force since Newton's second law, as well as the concept of Electromagnetic Force. The relationship of the two equations will allow us to find the magnetic field through the geometric relations of density and volume.

Where,
B = Magnetic Field
I = Current
L = Length
<em>Note:
is a direct adaptation of the vector relation
</em>
From Newton's second law we know that the relation of Strength and weight is determined as

Where,
m = Mass
g = Gravitational Acceleration
For there to be balance the two forces must be equal therefore

Our values are given as,
Diameter 
Radius 
Magnetic Field 
From the relationship of density another way of expressing mass would be

At the same time the volume ratio for a cylinder (the shape of the wire) would be

Replacing this two expression at our first equation we have that:



Re-arrange to find I


We have for definition that the Density of copper is
, gravity acceleration is
and the values of magnetic field (B) and the radius were previously given, then:


The current is too high to be transported which would make the case not feasible.
