Answer:
D) 4.9 m/s
Explanation:
Speed of Object in Free Fall
s = Rate of Acceleration, Due to Gravity × Length of Time
s = 9.8 × 2.0
s = m/s (Round Up to The Nearest Whole Number)
--
m/s = 9.8 ÷ 2.0 = 4.9 m/s

Answer:
The force a person applies to a simple machine
Explanation:
An input force is that variable that enters a simple machine to perform a particular job by multiplying the value of that input force.
As a typical example we can find a lever where a person introduces an input force, this force multiplies according to the mechanical advantage of the lever resulting in the work of a simple machine with more work.
The relationship between the charge flowing through a conductor, the current flowing through the conductor and the time is:
Q = It
Where Q is the charge, I is the current and t is the time of application of the current. Substituting the values:
48.96 = 1.39 x t
t = 35.2 seconds
