Answer:
1.54 s
Explanation:
Considering that the legs constitute 16% of the total weight of the man then mass,
The legs also constitute 48% of his height hence
The moment of inertia of a cylinder rotating about a perpendicular axis at one end is hence
We also know that the period is given by
Here, h=0.5H= 0.5*0.8784=0.4392 m
Taking g as 9.81 kg/m2 then
Answer:
D
Explanation:
30 m/s is the hypothenuse. The horizontal component will be x. Using trig, you can see that
On a roller coaster, the greatest potential energy is at the highest point of the roller coaster
Answer:
2805 °C
Explanation:
If the gas in the tank behaves as ideal gas at the start and end of the process. We can use the following equation:
The key issue is identify the quantities (P,T, V, n) in the initial and final state, particularly the quantities that change.
In the initial situation the gas have an initial volume , temperature , and pressure ,.
And in the final situation the gas have different volume and temeperature , the same pressure ,, and the same number of moles ,.
We can write the gas ideal equation for each state:
and , as the pressure are equals in both states we can write
solving for
(*)
We know = 935 °C, and that the (the complete volume of the tank) is the initial volume plus the part initially without gas which has a volume twice the size of the initial volume (read in the statement: the other side has a volume twice the size of the part containing the gas). So the final volume
Replacing in (*)
