The average angular acceleration of the fan is
The number of revolutions after time is given by
Acceleration is assumed to be constant, so and over the 2 second interval we have
so the answer is A.
Answer:50 miles per hour 50/1hr
Explanation:100 divided by 2 is 50, divide 2 by 2 thats 1
Answer:
Negative acceleration
Explanation:
We know that
v= u+at
Where v is the final velocity
u is the initial velocity velocity
a is the acceleration
t is time
When final velocity of train will be zero .
v=0
0= u+at
a=- u/t
So from above we can say that acceleration will be negative .When acceleration is positive then train will never come in rest position.
Explanation:
an electrical load is the part of an electrical circuit in which current is transformed into something useful. examples include a lightbulb, a resistor and a motor. a load converts electricity into heat, light or motion. put another way, the part of a circuit that connects to a well-defined output terminal is considered an electrical load.
Answer:
It is necessary to search for new sources of energy because the sources we have now are non-renewable and exhaustible. The usage of these sources are increasing day by day and if this continues then one day we wlii be left with none so it is necessary to search for new sources of energy
