Answer:
a. Volts = current x resistance
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Hence, Ohm's law gives the relationship between voltage, current and resistance of an electric circuit.
Answer:
The distance covered by puck A before collision is 
Explanation:
From the question we are told that
The label on the two hockey pucks is A and B
The distance between the two hockey pucks is D 18.0 m
The speed of puck A is 
The speed of puck B is 
The distance covered by puck A is mathematically represented as
=> 
The distance covered by puck B is mathematically represented as
=> 
Since the time take before collision is the same
substituting values
=> 
=>
Answer:
20 years Light.
Explanation:
There's no practical explanation just math's.
Wavelength = (speed) / (frequency)
Wavelength = (340 m/s) / (400 /s)
<em>Wavelength = 0.85 meter</em>
Speed = 22.8m/min
= 22.8 / 60
=0.38m/s
time = distance/ speed
= 467/0.38
= 1252.63s
