Answer:
New pressure group is N
Explanation:
The Repetitive Dive table has to be checked, the residual nitrogen for the maximum depth of 38 feet as a "D" diver, then add that to the actual dive time to get the total nitrogen time. The total nitrogen time and the maximum depth of 38 feet would put you on a pressure group N.
Answer: 1.64 *10^19 electrons
Explanation: In order to the explain this problem we have to consider the following:
The current= charge/time; so
as the electrons move in the tungsten wire we have:
0.526 C/s= N electrons per second* charge of electron=
N electrons/s= 0.526/1.6*10^-19= 3.28 *10^18 electrons/s
Then, during 5 seconds will pass:
3.28 *10^18 electrons/s*5 5s= 1.64 *10^19 electrons
Displacement of an object is equal to distance from starting point to end point.
Let's use positive numbers for movement towards east and negative numbers fro movements towards west. First movement is +50m, second movement is -30m. We add these numbers to find displacement.

Total displacement is 20m towards east.
The force vector that has a magnitude of 12.0 N. and is oriented 60° to the left of the (y) has the followings components:
To solve this exercise the formulas and procedures we will use are:
- v(x) = v * cosine (angle)
- v(y) = v * sine (angle).
Where:
- v= magnitude of the vector
- v(x) = component of the vector on the (x) axis
- v(y) = component of the vector on the (y) axis
- angle = angle
Information about the problem:
- angle = 60º
- v = 12.0 N
- v(x)= ?
- v(y)= ?
Applying the formula of the component of the vector in the (x) axis we have:
v(x) = v * cosine (angle).
v(x) = 12.0 N * cosine (60º)
v(x) =6 N
Applying the formula of the component of the vector in the (y) axis we have:
v(y) = v * sine (angle)
v(y) = 12.0 N * sine (60º)
v(y) = 10.39 N
<h3>What is a vector?</h3>
It can be said to be a straight line described by a point (a) and (b) that has direction and sense.
