Answer:
Explained
Explanation:
Given:
Ship travels due east from the Bar Harbor 38 miles before turning north
Yes it possible to calculate the exact direction of the ship by assuming there are no large islands in the way, and that the isolated ship does not cut off very far, then what we have here is a right triangle with a 72-mile as hypotenuse and a 38-mile as "adjacent" side. If θ is the angle out of Bar Harbor, we can write
, and θ = 58.14457°, or 58° 8' 40" north of east. That will be the exact direction.
Answer:
A. TRUE
B. TRUE
C. It depends on the mass of both the objects
D. TRUE
Elementary charge used to determine charges of other objects is equal to a charge of electron or proton. It's value is roughly
. All other charges are whole-number multipliers of this elementary charge, meaning that we multiply elementary charge by {...,-2,-1,0,1,2,...}.
To find out if the measured charge can be accepted we need to divide it with elementary charge to see if we get whole number as result.
There are three possible values of measured charge:
As we can see none of the possible values of a measured charge is whole-number multiplier of elementary charge so the researcher should not accept the value.
This charge can be achieved by using quarks which have value of 1/3 of elementary charge but they do not remain stable for long enough.
Hey there,
When you take away electrons<span> from an </span>atom<span>, it is no longer a neutral </span>atom<span>- it becomes a positive </span>atom<span>, and is also known as a cation.

Hope this helps :))
