As the time of motion increases, the velocity of the object increases downwards.
The given parameters;
- <em>acceleration due to gravity, g = -9.81 m/s²</em>
- <em>velocity of the object, v₀ = 9.8 m/s</em>
The final velocity of the object at different time is calculated as follows;
<em>when the time = 1 second;</em>
v = v₀ - gt
v = 9.8 - 9.8(1)
v = 0
<em>when the time = 2 second;</em>
v = v₀ - gt
v = 9.8 - 9.8(2)
v = -9.8 m/s
<em>when the time = 3 second;</em>
v = v₀ - gt
v = 9.8 - 9.8(3)
v = -19.6 m/s
Thus, we can conclude that as the time of motion increases, the velocity of the object increases downwards.

Answer:
168 Hz, 280 Hz and 392 Hz
Explanation:
The resonant frequencies for a closed pipe at one end is given by :
, n = 1,3,5...
The fundamental frequency, f₁ = v/4l = 56 Hz
For first overtone, put n = 3
For second overtone, put n = 5
For third overtone, put n = 7
So, the first three overtones are 168 Hz, 280 Hz and 392 Hz.
The geosphere interacts with the hydrosphere when water causes rock to erode. The atmosphere provides the geosphere with heat and energy for erosion, and the geosphere reflects the sun's energy back into the atmosphere.
Answer:
Resistors restrict current flow through a circuit.
(The electrons don't easily get from one side to the other)
High voltage is actually needed for to send power over long distances because if you use high current, a lot of the power is lost to the resistance in the wires.
