A control variable is the one element that is not changed throughout an experiment.A dependent variable is a variable whose variation does not depend on that of another.A independent variable is a variable whose value depends on that of another.
Answer:
Explanation:
The period of a simple pendulum is given by the equation
where
L is the lenght of the pendulum
g is the acceleration due to gravity at the location of the pendulum
We notice from the formula that the period of a pendulum does not depend on the mass of the system
In this problem:
-The pendulum comes back to the point of release exactly 2.4 seconds after the release. --> this means that the period of the pendulum is
T = 2.4 s
- The length of the pendulum is
L = 1.3 m
Re-arranging the equation for g, we can find the acceleration due to gravity on the planet:
Answer:
Average power of this circuit, P = 44.64 watts
Explanation:
It is given that,
The power factor of RC circuit,
The rms value of the AC voltage,
Impedance of the circuit, Z = 200 ohms
The average power of this circuit is given by the formula as follows :
P = 44.64 watts
So, the average power of this circuit is 44.64 watts. Hence, this is the required solution.
I’m guessing b because hydrogen is in your room and maybe eliminate to o but it also can be D
my final is: B!
The mass of the astronaut is still 65 kilograms. Mass is constant or doesn't change no matter where you are.
