Explain the relation between Joule and Erg.
2 answers:
Answer:
Both erg and Joule are units of Energy in the CGS and S.I system respectively.
Joule and erg can also be written as (kg m2/s2) and (g cm2/s2) respectively.
Explanation:
1 Joule = 107 erg ⇒ 107 kg m2/s2.
==> One erg of energy is the amount of work done when one dyne of force acts through a distance of one centimeter.
==> One Joule of energy is the amount of work done when one Newton of force (100,000 dynes) acts through a distance of one meter (100 centimeters).
==> That makes one Joule the same amount of energy as 10 million (10⁷) dynes.

Answer:
when the momentum of the vehicle moving at 30 km/h is higher than the one from the vehicle moving at 60 km/h
Explanation:
It's much harder to stop a freight truck moving at 30 km/h than a hot wheels car moving at 60 km/h.
Answer:
Explanation:
If I am not wrong
current = charge/time
All you have to take care of is the units should be in the same system
so
current = 12/(2*60) --------- 2 min = 2*60 sec
current = 12/120 = 0.1 amp
The gap between the two flasks is partially evacuated of air creating a near vacuum which significantly reduces heat transfer by conduction or convection
