Any work a machine does is commanded by a human (in code or any input) or else they are sentient, so humans are still required.
Answer:
its because static electricity my guy

Full Question:
Consider an automobile with a mass of 5510 lbm braking to a stop from a speed of 60.0 mph.
How much energy (Btu) is dissipated as heat by the friction of the braking process?
______Entry field with incorrect answer Btu
Suppose that throughout the United States, 350.0 x 10^6 such braking processes occur in the course of a given day.
Calculate the average rate (megawatts) at which energy is being dissipated by the resulting friction.
______Entry field with incorrect answer MW
Answer:
Energy dissipated as heat = 852.10 Btu
Average rate of energy dissipation = 3.64 MW
Explanation:
1 lb = 0.453592 Kg
Mass = 5510 lb = 0.453592 * 5510 Kg = 2499.29 Kg
1 mph = 0.44704 m/s
Velocity = 60 mph = 60 * 0.44704 m/s = 26.82 m/s
Let E be equal to energy acquired


Energy dissipated as heat:

E = 852.10 Btu
Energy dissipated throughout the United States

Average power rate in MW, P

Answer:
the rods are insensitive to red light.
Explanation:
People, such as pilots, who have to move quickly from lighted surroundings to night
darkness use red light illumination because human eye is less sensitive to longer wavelength ( rhodopsin in rods cells of eye).Using red goggles,the cones can receive enough light to provide photopic vision. Whereas rods are less sensitive to longer wavelength (red light).So, the crew members remains dark adopted.
Hence, (d) is the correct answer.
<u>First question:</u>
Density = 
Mass = density × volume
The density of the cube is 1.2g/cm³
The volume of the cube is given by side × side × side:
Volume = 7cm × 7cm × 7cm = 347cm³
Mass = 1.2g/cm³ × 343cm³ = 411.6g
*Hint: Just apply the formula Density =
