Answer:
i think option (a)
because they need zoom in
To solve this problem, apply the concepts given from Ohm's Law. From there we will obtain the derivative of the function with respect to time and with the previously given values we will proceed to find the change in current as a function of the derivative
Here
I = Current
V = Voltage
R = Resistance
Taking the derivative we will have,
Our values are given as,
Replacing we will have that
Rearranging to find the current through the time,
Therefore the change of the current is -0.000026A per second
We're so good here on Brainly, we can answer it
even WITHOUT seeing the choices.
Time = (displacement) / (magnitude of average velocity) .
False. you have to find out how many seconds are in the 25 min. 60 x 25 is 1500sec. Then multiply 1500 by .75 to get 1,125m. There are 0.001 kilometers in a meter. Move the decimal point three spaces to convert m to km. 1,125m becomes 1.125km
Answer:
Explanation:
A) 215 + 45.0 = 260 km/h West
B) 215 - 45.0 = 170 km/h West
C) √(215² + 45.0²) = 219.6588... 220 km/h
θ = arctan(45.0/215) = 11.8214... 11.8° S of W
