doubling the radius will have a greater effect
v of cylinder=pi x square of radius x hieght
lets take an example,r=2,h=2
v=8pi
doubling the hieght,h=4
v=16pi ie twice the initial volume
doubling the radius,r=4
v=pi x 16 x 2
=32 pi ie four times the initial volume
therefore radius makes a bigger difference
Answer:
optical
Explanation:
Polarization fall under optical property of material.
Polarization is a property of certain electromagnetic waves in which the direction and the magnitude of electric field are related in some way. Plane polarized light consist of waves in which direction of vibration of waves is same for all waves. Light may be polarized by reflection or by passing it through filters.
Answer:
twice as long
Explanation:
If Stardust managed to cover 50 miles on his first trip to the forest, and later managed to cover 300 miles by going 3 times faster, then we can easily come to the result as to how much more time Stardust needed comparably between the two trips, just by using these three numbers.
If Stardust was going 3 times as fast on the second trip, then we need to multiple that number with the number of miles of the first trip:
50 x 3 = 150
This means that Stardust managed to cover 150 miles on the second trip in the same amount of time as the 50 miles in the first trip. In order to see how much more time Stardust needed to cover the 300 miles, we just need to divide the total amount of miles, with the 150 miles of the 3 times faster speed:
300 / 150 = 2
So we get a result of 2, meaning that Stardust needed twice more time to cover the 300 miles, than what he needed to cover the 50 miles of the first trip.
