Answer: it is better to use renewable energy. Some of the benefits are: The main advantage is the practically zero emission of greenhouse gases (GHG) and other pollutants that affect climate change.
They help decrease pollution-related illnesses.
It does not need large amounts of water for its operation.
Kinetic energy = (1/2) (mass) (speed)²
= (1/2) (1.4 kg) (22.5 m/s)²
= (0.7 kg) (506.25 m²/s² )
= 354.375 kg-m²/s² = 354.375 joules .
This is just the kinetic energy associated with a 1.4-kg glob of
mass sailing through space at 22.5 m/s. In the case of a frisbee,
it's also spinning, and there's some additional kinetic energy stored
in the spin.
Answer:
2.5km
Explanation:
Assuming you also walk with the average human walking speed of 5 km/h. We know that speed=distance/time and now making distance the subject, distance is a product of speed and time. The time is 30 minutes, expressed in hours will be 30/60=0.5 hours. Substituting 5km/h for speed and 0.5 hours for time then the diatance covered will be
Distance=5*0.5=2.5 km
Answer:for each (used with units to express a rate). or divided by a line in the direction of.
