Answer:
P = 1.99 10⁸ Pa
Explanation:
The definition of the bulk module is
B = - P / (ΔV / V)
The negative sign is included for which balk module is positive, P is the pressure and V that volume
They tell us that the variation in volume is 9.05%, that is
ΔV / V = 9.0Δ5 / 100 = 0.0905
P = - B DV / V
P = 2.2 10⁹ (0.0905)
P = 1.99 10⁸ Pa
First of all, we need to convert the final angular velocity from rpm (revolutions per minute) to rad/s. Keeping in mind that
We have
the angular acceleration is given by
where
is the initial velocity (in this case, zero), and
is the time needed to accelerate the drill to its final velocity. Using
, we can calculate
:
A)<span>the production of bubbles by the plant when it is in darkness because in the dark the plant respires and when it does so it produces CO2 gas not O2</span>
Answer:
C. 960.8°C
Explanation:
When freezing, silver changes state from liquid to solid. Also, when melting, silver changes state from solid to liquid. Therefore, the freezing point and melting point share the same temperature. In this case, 960.8°C
