Answer:
Energy Density: 129.412
Explanation:
First of all, let's convert the battery weighing from pounds to kilograms:
0.525 lb x = 0.238 kg
Now let's convert the electrical energy from kcal to Wh:
30.8 kcal x = 30.8 Wh
Now we can calculate energy density as follows:
Energy Density =
Energy Density = 129.412
Answer:
Students learn about the fundamental concepts important to fluid power, which includes both pneumatic (gas) and hydraulic (liquid) systems. Both systems contain four basic components: reservoir/receiver, pump/compressor, valve, cylinder.
Explanation:
Answer: speed is different from velocity and acceleration
Explanation:
Acceleration is rate of change of velocity per unit time and velocity is rate of change of displacement(shortest path between initial and final point) per unit time. but speed is Distance per unit time. The difference between speed and other two terms is that, speed is scalar i.e it has only magnitude, velocity and acceleration has both velocity as well as direction.
- a(acceleration) = dv/dt
- v(velocity) = ds/dt
- speed = distance/time
Don't repeat yourself (DRY, or sometimes do not repeat yourself) is a principle of software development aimed at reducing repetition of software patterns,[1] replacing it with abstractions or using data normalization to avoid redundancy.
