Answer:
10.29 cm/s
Explanation:
Discharge in to the bowl = 17.0 cm³/s
Diameter of the bowl, d₁ = 1.45 cm
Now,
Rate at which water level rise at its diameter =
also,
Area of cross-section =
or
Area of cross-section = 1.651 cm²
Therefore,
Rate at which water level rise at its diameter =
or
Rate at which water level rise at its diameter = 10.29 cm/s
Answer:
For him being such a fat bear, it would have taken alot of work
Explanation:
Answer:
W(fric) = -12000 J
Explanation:
Given that
mass ,m= 80 kg
Initial speed ,u= 0 m/s
Height ,h= 15 m
Final speed ,v= 0 m/s
We know that
Work done by all the forces = Change in the kinetic energy



W(fric)= - m g h
W(fric) = - 80 x 10 x 15 ( g=10 m/s²)
W(fric) = -12000 J
negative sign indicates that force and displacement is in opposite direction.
