Answer:
= -8πx
Explanation:
If you need calculate
You can use the Ampere's Law
= μ
Where : Current passing through the window
μ : Free space’s magnetic permeability
μ = 4πx
Then
= (3-5)4πx
= -8πx
Answer:
α = 3070rev/s^2
θ = 5541.66 revolutions
Explanation:
Given;
Operating angular speed w = 350000 rpm
time t = 1.9s
Angular acceleration = change in angular speed/time
Angular acceleration=350000rpm×1/60 min/sec ÷ 1.9s
Angular acceleration α = 3070rev/s^2
Number of revolutions θ = 1/2 × α × t^2
Since initial angular speed is zero
Substituting the values;
θ = 1/2 × 3070 × 1.9^2
θ = 5541.66 revolutions
Tiffany has been waiting for weeks to see one particular meteor shower that peaks around august 12. Tiffany is waiting to see Perseid Meteor Shower.
A very bright supermoon known as a "Sturgeon Moon" may make it difficult for photographers to capture this year's climax of the Perseid Meteor Shower tonight (August 12). The Perseid meteor shower, which peaks overnight on August 12 and 13, is one of the most powerful annual meteor showers and occurs between July 14 and September 1. Unfortunately, that falls on the night of this month's full moon, which became fully illuminated yesterday night (Aug. 11). The meteor shower is named after the constellation, the northern constellation Perseus.

When car is at rest the steaks makes makes vertical lines
which means the rain is falling in vertically downward direction
Now when car is moving with some speed v
Now the steaks makes and an angle 45 degree
So here we can say that relative velocity of rain with car is 45 degree
Now this is the resultant speed of rain in car frame
now if relative velocity makes 45 degree angle so this vector must have same components in vertical and horizontal direction
Since we know that relative velocity is resultant of rain velocity and car velocity so we can say here its two components are rain velocity and car velocity
So these two components must be of same magnitude
as it makes 45 degree
because when two vector are of same magnitude then the resultant vector always makes 45 degree with them if these two vectors are perpendicular to each other
car is moving at same speed as the speed of rain
