Answer:
A) An organism with favorable genetic variation will tend to survive and breed successfully.
Explanation:
In an ecosystem, organisms that don't have the best genetic variation will die off, leaving the more genetic favored ones to survive and become better as a whole.
Answer:
20cm
It is one of the characteristics of a plane mirror that, the distance of the plane mirror from the object is equal to its distance from the image. Therefore, given distance between object and mirror = 10cm. Distance between mirror and image = 10cm. Thus, the distance between object and image = 10 + 10 = 20cm.
Explanation: :0
<span>1.) It is 6.00km from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10.0km/hr (which uses up energy at the rate of 700W ), or you could walk it leisurely at 3.00km/hr (which uses energy at 290 W).
A.)Which choice would burn up more energy?
running or walking?
b.)How much energy (in joules) would it burn?
c.)Why is it that the more intense exercise actually burns up less energy than the less intense one?

Best Answer: running, at 10 km/hour for 6 km is
6 km / 10 km/hour = 0.6 hour or 36 min
energy used is 700 watts or 700 joules/s x 36 min x 60s/min = 1.512e6 joules or 1.5 MJ
walking, at 3 km/hour for 6 km
6 km / 3 km/hour = 2 hour or 120 min
energy used is 290 watts or 290 joules/s x 120 min x 60s/min = 1.872e6 joules or 1.8 MJ
C) should be obvious
PS, this has nothing to do with potential energy.

I assume the watt consumption is per hour. Then running 6km at 10.0 km/h results in 700*6/10 = 420 w.h and walking in 290*6/3 = 580 w.h So walking would burn up more energy (kwh)
b) 1 kilowatt hour = 3 600 000 joules
so 420 wh = 0.42 kwh = 1.51.10^6 joule
c) when you put more effort in making the distance your energy is used more efficient.

Answer:
First one
Explanation:
Maybe because example if a ball that has less mass bounces higher than the one w/more , then a bowling ball should be able with more force.
hope that helped:/
