Answer:
Initial height L = 323.3m
Explanation:
Given:
Change in Length ∆L = 19.4cm 0.194m
Change in temperature ∆T = 41 -(-9) = 50°C
Coefficient of linear Thermal expansion of steel k = 12 × 10^-6 m/mK
Using the formula for linear expansion:
∆L = Lk∆T
L = ∆L/k∆T ....1
Substituting the given values into equation 1
L = 0.194/(12 × 10^-6 × 50)
Initial height L = 323.3m
Answer:
i hope it help
Explanation:
It's possible to step 12 volts down to 6 volts by incorporating a pair of 10,000-ohm resistors into the circuit. Cut two lengths of wire, and strip each wire of 1/2 inch of insulation at each end. Attach one end of the first wire to the positive terminal on the power supply.
I believe the answer is <u>C</u>
I hope this helps! Have a nice day, make sure to take care of yourself. You're loved <3
The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis.
