Answer:
(a). The density of the wood is 
(b). The absolute pressure at the bottom of the tank is
.
Explanation:
Given that,
Side of cube = 15.0 cm
Depth = 50 cm
Tension = 6.615 N
We need to calculate the volume of the wood
Using formula of volume


We need to calculate the density of the wood
Using buoyant force


Put the value into the formula

Put the value into the formula


(b). We need to calculate the absolute pressure at the bottom of the tank
Using formula of absolute pressure

Put the value into the formula


Hence, (a). The density of the wood is 
(b). The absolute pressure at the bottom of the tank is
.
Answer: 2.90mi/hr/s
Explanation:
Acceleration = Final Velocity - Initial over time
Acceleration = 27.8mi/hr over 9.58s.
Answer is 2.90mi/hr/s
Hope I Helped!
Her acceleration would increase, if mass decreases than the acceleration would increase
Answer:
Yes, the sugar molecules produced from photosynthesis can be rearranged into different compounds to carry out life processes such energy producing compounds, energy storage compounds, body building compounds, and compounds of other types of food
Explanation:
a) The sugar can be broken down in a plant cell to produce ATP and then energy through cellular respiration as follows;
C₆H₁₂O₆ + O₂ 6CO₂ + 6H₂O + ATP
The produced energy can be used as power for cellular activities, such as the synthesis of protein and cell division
b) The produced sugar can be linked together by enzymes to form starch which is a form of chemical storage of energy as follows;
Sugar C₆H₁₂O₆ transformed into starch (C₆H₁₀O₅)ₙ
c) The sugar can be used in building the plant body by forming cellulose which is a form of starch
d) The sugar can be transformed into proteins and fat which are other types of food such as compounds containing sugar produces compounds containing fat based compounds
Some work will be done on friction between wheels and road but it is negligible compared to work done on friction on breaks.
W = Ek = (m*v^2)/2 = 2000*22^2/2 = 1000*22^2 = 484KJ
Because car is not changing its potential energy, there is no work to be done on while changing it which means that all goes on changing kinetic energy (energy of motion)
