Answer:
Average speed: approximately 
.
Average velocity: approximately 
(to the north.)
Explanation:
Consider an object that travelled along a certain path. Distance travelled would be equal to the length of the entire path.
In contrast, the magnitude of displacement is equal to distance between where the object started and where it stopped.
In this question, the path George took required him to travel 
in total. Hence, the distance George travelled would be 
. However, since George stopped at a point 
to the north of where he started, his displacement would be only 
to the north.
Divide total distance by total time to find the average speed.
Divide total displacement by total time to find average velocity.
The total time of travel in this question is 
.. Therefore:
.
.
If the density of the object is lower than the density of the liquid it is floating in then it will float. if the density is larger it will sink. density is mass/volume
Answer:
Resistance, 
Explanation:
Given that,
Voltage of the battery, V = 9 volts
Current produced in the circuit, I = 17 A
We need to find the resistance when shorted by a wire of negligible resistance. It is a case of Ohm's law. The voltage is given by :
So, the resistance in the circuit is 0.529 ohms. Hence, this is the required solution.
Answer:
Ohm's Law
Explanation:
The relationship: 
where V represents the voltage across a resistor of resistance "R" through which a current (I) flows,
is known as Ohm's Law in honor of Georg Ohm, who discover this proportionality.
Answer:
look it up
Explanation:
An electrical shock is received when electrical current passes through the body. ... Whenever two wires are at different voltages, current will pass between them if they are connected. Your body can connect the wires if you touch both of them at the same time. Current will pass through your body.
