An egg falls out of a nest of a tree. It freefalls for 1.5 seconds, and then hits the ground. From how high up did the egg fall?
Alika [10]

Answer:

11.025m

Explanation:

Using kinematics,

u = Initial velocity = 0.

t = Time taken = 1.5sec.

a = Acceleration from gravity = 9.8m/s^2

Distance = s

= ut + 1/2 * a * t^2

= 0 + 1/2 * 9.8 * (1.5)^2

= 11.025m

ivann1987 [24]

Answer:

64.5

Explanation:

(m1 + m2) v initial = (m1 * v1 final) + (m2 * v2 final)

(92 + 8)(-7) = (92 x 2) + (8 x v2 final)

(100)(-7) = (184) + (8 x v2 final)

-700 = (184) +  (8 x v2 final)

-516 =  (8 x v2 final)

-516/8 = v2 final

-64.5 = v2 final

A wire carries a 2a current. what is the current in a second wire that delivers twice as much charge in the same amount of time?
Soloha48 [4]

Answer:

4A

Explanation:

Current is charge per time.  So if the second wire delivers twice as much charge in the same amount of time, it must have twice the current.

2 × 2A = 4A
