Answer:
It takes 3 minutes.
Explanation:
The distance between the two subways is 3 miles.
The train travels at an average speed of 60mph (miles per hour).

We have to convert hours to minutes and we do that by cancelling out the hours and replacing it with minutes.
There are 60 minutes in an hour so we use that, 1 hour/60 minutes and multiply it to the existing speed we have.
The result is 1 mile per minute.
We then multiply the miles by 3 since that is how much we want and we get 3 minutes.
Answer:
true
Explanation:
because the bonds in that element can only be shared but not transferred , but sometimes it depends on the element
Answer:
i = 61 degree
Explanation:
Given,

Now, by the snell's law

Now,
Sin i / sin r = n 2 / n 1
sin i / sin r (45 - 24.09) = 2.45 / 1
i = 60.97 degree
i think the answer is D.
heating surface water causes it to evaporate and enter the air as a gas.
Since an alpha particle has 2 protons and no negative particles (electrons) to balance the net charge, its charge is
Q=2(1.6e-19)=3.2e-19C.
The force on a charged particle is F=QE so
(3.2e-19C)(600N/C)=1.92e-16N
