Calculate how much energy (in Joules) it takes for a bird of 134.6 g to fly 34.8 m to the top of a tree from the ground. Calculate the value assuming only vertical displacement. Recall the gravitational constant is 9.81 m/s2.

45.51 J

Explanation:

Energy in relation to vertical displacement = P.E.

P.E. (potential energy) = mgh

m = 134.6g = 0.1346 kg

g = 9.81m/s²

h = 34.8m

since, P.E = mgh = 0.1346 × 9.81 × 34.8

= 45.51J

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
