Answer:
kinetic Energy = 12.58 GJ
Explanation:
1 metric ton is equal to 1000 kg
then,
93000 metric ton
Mass is m = 93000 x 1000 kg
speed is v = 32 knots
1 knot is 0.514 m/s
then ,
v = 32 x 0.514 = 16.448 m/s
To solve for the Kinetic Energy (KE), we have;
KE = 0.5 x m x v²
KE = 0.5*93000*1000*(16.448)²
= 12.58 x J
= 12.58 GJ
Answer:
Explanation:
Let be % of
at time
(time in minutes).
Amount of in room=Volume of room
Rate of change of in room=Volume of room x
Rate of inflow of =
Rate of outflow
Therefore rate of change of is
% rate of change is
Therefore we have:
Integrate both:
InIn
Raise both sides to base ,
Initially, there's only 0.25% of ,
Now substitute and
