Answer:
Explanation:
Given
initial angular velocity is
when motor is turned of it started decelerating with angular acceleration
angle turned before coming to halt
here final angular velocity is zero
No of revolutions will be
Answer:E. an object will remain in uniform motion unless acted upon by a force
Explanation:
The load value for interrupts every one milliseconds is
The load value for interrupts every millisecond is
However, we can only load integer values, therefore we apply
When the delay is 1 ms, it is accurate, but when the delay is 1 us, it is a little bit less. We are unable to provide an accurate 1 us delay interrupt because this requires a fractional value was calculated.
<h3>What does a SysTick timer do?</h3>
- The systick timer has an auto reload and a 24-bit countdown timer.
- An RTOS scheduler typically uses it to provide a periodic interrupt.
- The Cortex-M CPU clock is used as the default clock source for the systick timer.

Answer:
The sound level of the 26 geese is
Explanation:
From the question we are told that
The sound level is
The number of geese is
Generally the intensity level of sound is mathematically represented as
The intensity of sound level in dB for one goose is mathematically represented as
Where I_o is the threshold level of intensity with value
is the intensity for one goose in
For 26 geese the intensity would be
Then the intensity of 26 geese in dB is
From the law of logarithm we have that
