Answer:
option (a)
Explanation:
To make a galvanometer into voltmeter, we have to connect a high resistance in series combination.
The voltmeter is connected in parallel combination with teh resistor to find the voltage drop across it.
An ideal voltmeter has very high resistance that means it has a resistance as infinity.
Just use the formula
speed=Frequency X Wavelength
where speed of electromagnetic waves in vacuum is always 3X10^8
Answer:
A
Explanation:
Voltage, V = Current, I x Resistance, R (V is directly proportional to I where R is constant of proportionality)
This means that when Voltage is increased, Current increases and when voltage is decreased, current decreases (and the inverse is true). Through all this though, resistance remains constant regardless.
You need the picture. However, since I'm doing PLATO as well, here's the answer:
The third position in which the cyclist is going downhill is the position where the cyclist has the maximum kinetic energy. The other two photos show that the biker has more potential energy.
Thanks, let me know if this helped!
B. velocity is the speed in any given direction.
