Answer:
866.92 N
Explanation:
mass of shark, m = 92 kg
density, d = 1040 kg/m^3
Volume, V = mass / density
V = 92 / 1040 = 0.08846 kg/m^3
The lift force is the buoyant force acting on the shark is
Lift force = Volume x density of water x g
Lift force = 0.08846 x 1000 x 9.8
Lift force = 866.92 N
Thus, the lift force is 866.92 N.
Answer:
The maintenance of fluid balance during exercise. Sodium also promotes retention of ingested fluids and leads to an increased plasma volume response during rehydration. The primary goal of supplementation should be considered, fluid vs carbohydrate provision, and the beverage composition altered accordingly.
Immediately after the switch is closed, the capacitor acts like a short circuit for a very small time. We can calculate the currents through each resistor by first calculating the total resistance:
Req = 1/(1/3+1/6) + 8 = 1/(3/6) + 8 = 2 + 8 = 10 ohms.
IR1 = E / Req = 42 / 10 = 4.2 A.
VR2 = VR3 = E * R23 / Req = 42 * 2 / 10 = 8.4 V
IR2 = VR2 / R2 = 8.4 / 6 = 1.4 A.
IR3 = VR3 / R3 = 8.4 / 3 = 2.8 A.
