Answer:
30m/s
Explanation:
From law of motion equation
Vf= Vi + at
Where Vf= final velocity
Vi= initial velocity=0(the car started at rest)
a= acceleration= 3m/s2
t= time= 10s
Then substitute into the equation to get the final velocity.
Vf= 0+(10×3)
Vf= 30m/s
Hence, the car's final velocity is 30m/s
Part 1
If water does not spill at the top point of the circular motion then for the minimum speed condition we can say normal force will be zero at the top position
given that
R = 1 m
g = 9.8 m/s^2
now from above equation we have
Part b)
for minimum value of angular speed we will have
Answer:
D
Explanation:
The reproduction parts of the plant are in the flower and around it so this would eliminate the plants ablity to reproduce.
Answer and Explanation: One ATP release approximately 30.5kJ/mol of energy. Using Avogadro's constant, it is known one mol corresponds to molecules, so 106 ATP molecules releases:
E =
E = J
A cell is approximately a sphere. Volume of a sphere is given by
V =
Changing radius from mm to m:
r = m
Then, volume is
V =
V = m³
Power density is given by
power = 12.8. W/m³
Power density for a the cell is 12.8. W/m³.
Power density for battery is
100 cm³ = m³
power =
power = W/m³
Comparing cell and battery, battery has a greater power density.
