Answer: drying towels at the beach.
Explanation:
Radiation simply has to do with the energy that is gotten from a particular source and then goes through some materials. It simply means the way energy is being transmitted as waves or heat through a certain medium.
From the options given, the scenario whereby a radiation takes place is when drying towels on the beach.
No. it is not good for people to live on Mars.
Answer:
P = 24.32 W
Explanation:
The question is, "Two resistors 5 Ω and 10 Ω are connected in parallel with a 9 V power supply. Calculate the output power of the power supply.".
The voltage of the power supply, V = 9 V
Resistor 1, R₁ = 5 Ω
R₂ = 10 Ω
The equivalent of parallel combination of resistors is given by :
The power of the output is given by :
So, the output power is equal to 24.32 W.
First, you should convert the initial and final velocities from km/h to m/s. You should end up with Vi= 25m/s and Vf=10m/s (both rounded).
Now, you can use the equation Vf=Vi+A(t)
Rearrange it to A is isolated: A= Vf-Vi/t
A=(10-25)/6
A=-2.5m/s^2
