Hey
Good question
How can we know if I planet was once inhabited by life? There diferent tequnecs for this. The first would be searching in the soil for fossilized microbes. in June of 19, 1976 Viking 1 was launched on its way to mars to began the search of life els wear. What this little lab did was drill a hole in the marsion terrain and take a sample of its soil to search for microbes or microbe fosles. Sadly it did not find anything. Other technics are to search for ruins on the planet or exoplanet. I do not have much to say about this method because it has never been used.
Hope it helped (i wrote all that).

Below is a picture of Carl Sagan next to the Viking Voyager 1. Obveosly this is just a modal. you could not breathe on mars.
Answer:
ω' = 2.5 rad/s
Explanation:
mass of cockroach, m = 4 kg
mass of disk, M = 6 kg
Radius of disc= R
initial angular velocity, ω = 2 rad/s
Let the final angular velocity is ω'
As no external torque is applied, so the angular momentum is constant.
Angular momentum = Moment of inertia x angular velocity
I ω = I' ω'
ω' = 2.5 rad/s
Answer:
The power dissipated in a resistor is 117.54 watts.
Explanation:
Given that,
Peak voltage of the Ac generator, V = 230 V
Frequency, f = 210 Hz
Resistance, R = 225 ohms
We need to find the power dissipated in a resistor. The power generated is given by :
So,
So, the power dissipated in a resistor is 117.54 watts. Hence, this is the required solution.
