Answer:
If the speed is 70 mile/hour, the time to drive the 256 miles is:
T = 256/70 = 3.66 hours = 3 hours and 39.6 minutes
If you leave at 3:00, then at 6 hours and 39.6 minutes, you will get there.
Hope this helps!

chemical to thermal to electromagnetic
Explanation:
The best statement that shows the energy transformations that took place is from chemical to thermal to electromagnetic energy.
- In all isolated systems, energy is neither created nor destroyed but transformed from one form to another according to the law of conservation of energy.
- The firewood contains a chemical potential energy at rest. This energy is contained in the carbon chains of organic compounds it houses.
- When combustion takes place, kinetic energy in form of thermal energy is liberated. The bulk is in form of heat.
- This energy dissipates in all direction as a form of radiant electromagnetic energy in the infra-red range.

The elctromagnetic spectrum ranges from the radiowaves to the gamma rays. The whole spectrum is shown in the attached picture. But the optical telescope can only see the visible region. So, it only covers from the 400 nm to 700 nm frequency. It follows the ROYGBIV colors, where red has the highest frequency and violet has the lowest frequency.
Answer:
Explanation:
Distance between q1 and q2,d=20 cm
1m =100 cm
Electric force on charge q3 due to charge q1
(away from q1)
Electric force on charge q3 due to charge q2
(attract toward q2)
Net force=
