R=U/I so R= 7V/0.5A = 14 Ω
Now we just substract botg resistors from the total to get R3: 14 - 4 - 1= 9Ω
Answer:
Explanation:
<u>The pressure of a Fluid</u>
A fluid of density exerts pressure at a distance y (deep) given by
Where g is the acceleration of gravity or
This formula computes the pressure assuming the initial pressure is 0 at fluid (water in this case) level.
Knowing the measured pressure, we can know how deep the diver went by solving the equation for y
Let's plug in the given values
Thus
You're saying that it is the same thing to add or subtract B. This means that B must be the zero vector.
This works with numbers as well, if you feel more familiar to think it this way: in general, if you add something to a number you make it bigger, whereas if you subtract it, you make it smaller.
The only way to cause adding and subtracting to be the same thing is to add or subtract zero: in both cases, you're doing nothing.
Answer:
a star in andromeda
Explanation:
all of the other objects are in the milkyway (where we are) and the andromeda galaxy is 2 million light years away from us
