Angular acceleration = (change in angular speed) / (time for the change)
change in angular speed = (zero - 2,600 RPM) = -2,600 RPM
time for the change = 10 sec
Angular acceleration = -2600 RPM / 10 sec = -260 rev / min-sec
(-260 rev/min-sec) x (1 min / 60 sec) = <em>-(4 1/3) rev / sec²</em>
Since the acceleration is negative, the motor is slowing down.
You might call that a 'deceleration' of (4 1/3) rev/sec² .
The average speed is 1/2(2,600 + 0) = 1,300 rev/min = (21 2/3) rev/sec.
Number of revs = (average speed) x (time) = (21 2/3) x (10sec) = <em>(216 2/3) revs</em>
I think jogging/running/walking because you don't need any equipment and you can structure around it on your own time.
Out of the following choices given, hydraulic balances performs measurement in a closed compartment with no air currents to disturb measurement. The correct answer is C.
Answer:
right is the correct answer to the given question .
Explanation:
In this question figure is missing
The main objective right-hand rule to decide the position of the magnetic force on the positive force acting, either the position of the thumb of a right hand with in position of v, the fingers throughout the position of B1, and a right angles throughout the position of F1 to the hand positions.
So 
- So from the magnetic right hand rule the direction of the magnetic field in front of a wire is right .
- All the others options are incorrect because they do not give the direction of the magnetic field in front of a wire is right .
mass of first player = 82 kg
speed of first player = 4.1 m/s (towards North)
mass of second player = 76 kg
speed of second player = 3.4 m/s (towards East)
now the two players will collide and stick together so here since there is no external force on the system of two players so we will say momentum of system of players will remain conserved
So here we will have


now after collision they both move together with same speed so we will have



so the magnitude of the velocity after they collide is given as


direction of motion is given as


so they both will move 52.4 degree North of East after collision
