Answer:
a change in the state of matter
Step-by-step explanation:
The current in the 2nd case is 102 A
Step-by-step explanation:
The relationship between voltage, current and resistance in an electric circuit is given by Ohm's law:

where
V is the voltage
I is the current
R is the resistance
In this problem we are given two sets of data for the current and the resistance, while the voltage is kept constant. This means that we can write:

where
is the current in the 1st case
is the resistance in the 1st case
is the resistance in the 2nd case
Solving for
, we find the current in the 2nd case:

Answer:
The answer is 570 feet.
Step-by-step explanation:
First, the bird is 520 feet HIGH.
The diver is 50 feet BELOW sea level, which is also -50.
To find the difference, you would SUBTRACT right?
So 520 - -50 OR 520 + 50 (This is because two negatives make a positive, and you are also subtracting negatives, which in turn means adding).
520 + 50 = 570 - HOPE THIS HELPED!
Speed = Distance ÷ Time
Distance = 2797.2
Time = 0.15
2797.2 / 0.15 = 18,648
Speed = 18,648
