No,the poping of microvave is not same there time is different
Answer:
Option A is the correct answer.
Explanation:
The instantaneous acceleration = Change in velocity in velocity/Time taken
The slope of the graph should give instantaneous acceleration.
Slope of a graph = Change in value of Y -axis / Change in values of X -axis
Comparing both the equations
Change in value of Y -axis = Change in velocity in velocity
Change in values of X -axis = Time taken
So velocity values should be on the Y axis and Time values should be on the X axis.
Option A is the correct answer.
Given that,
Angular velocity = 0.17 rad/s
Angular acceleration = 1.3 rad/s²
Time = 1.7 s
We need to calculate the angular velocity
Using angular equation of motion
Put the value in the equation
We need to calculate the angular displacement
Using angular equation of motion
Put the value in the equation
We need to calculate the velocity at point A
Using equation of motion
Put the value into the formula
We need to calculate the acceleration at point A
Using equation of motion
Put the value in the equation
Hence, (a). The velocity at point A is
(b). The acceleration at point A is
Fatigue is the number one cause of accidents.
