Answer:
D
Explanation:
Clearly you can't help the environment by throwing waste in the area, polluting it, or burning it all up, so D would be our only option.
Have a good day :)
Answer:
Explanation:
To analyze the behavior of black bears during the night. To describe how black bears adapt to life near human. To evaluate the decline in the number of black bear.
We apply the gravity calculation expressed in the formula: g=GM/r2
where G is the gravitational constant, m is the mass and r is the radius
r=√GM/g
(1) Radius = √6.674e-11*5.972e24/8 = 7058 kms Earth radius or surface of earth from center of earth= 6400 kmsSo r= 658 kms from surface of earth.
Gravity 8m/s2 will be at 658 kms from surface of earth.
(2) half gravity= 9.8/2= 4.9 m/s2 Radius=√6.674e-11*5.972e24/4.9 = 9019 kms Half Gravity will exist at 9019-6400= 2619 kms from surface of earth.
Matter is a substance and the three types are solid liquid and gas
Energy = Power x Time
Energy = 20W x 10s
Energy = 200 joules
