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.
Hi there!
1.
The period of a pendulum can be calculated using the following equation:
T = period (s)
L = length of string (m)
g = acceleration due to gravity (m/s²)
Plug in the values:
2.
Calculate the period:
Frequency is the reciprocal of the period, so:
Answer:
36 grams of water
Explanation:
mass of H2O = 0.5 x 18 = 9g
