A snowball picks up speed as it rolls down the mountain.<em> (D)</em>
Since the description includes acceleration ("picks up speed"), we know that the forces on the snowball must be unbalanced.
The magnitude of acceleration is
(change in speed) divided by (time for the change) .
Between the two points on the graph ...
-- Find the change in speed. (usually the y-axis)
-- Find the change in time. (usually the x-axis)
Divide (change in time) by (change in speed) between the two points.
That quotient is the average magnitude of acceleration during that time.
If the graph happens to be a straight line, then the magnitude of acceleration
is just the slope of the line.
I would say the last one but I’m not sure if I’m directly correct ..
Answer:
C) High voltage to low voltage
Explanation:
At a power plant, there is a production of electricity at a high voltage compared to the voltage provided to our home.
Voltage of about 12 KV is produced by power plant which is then converted into about 400 KV or greater (depending upon the countries) to transfer electricity from power plant to city Grid station using Step-up transformer. At City Grid station, Step-down transformer is used to convert high voltage (about 400 KV) to low voltage (about 13 KV) to transfer electricity from grid station to the city. Then this low voltage (about 13 KV) again converted to 220 V using Step-down transformer for household usage. So, overall about 12 KV voltage at power plant is converted into 220 V for household usage using step-up and step-down transformer at different stages.
