Answer:
Processes are all the related activities (parts) inside the system that work together to make it function. ... It's important that processes are effective at what they do so that the system can run efficiently. Processes are the sequence of activities intended to produce a particular result.

Car 2 is travelling in a much higher speed than Car 1.But they are travelling or meeting in the same acceleration.
Answer: it is B
Explanation: A penumbral lunar eclipse occurs when the Moon passes through Earth's penumbra. The penumbra causes a subtle dimming of the lunar surface, which is only visible to the naked eye when about 70% of the Moon's diameter has immersed into Earth's penumbra.
Answer:
11.34 m/s
Explanation:
Force F = 25 N
Lenght of application l = 16.5 cm = 0.165 m
Time of application t = 1 sec
Radius of wheel r = 33.0 cm = 0.33 m
Moment of inertia I = 1200 kg·cm^2 = 0.12 kg-m^2
Let us assume he rides a fixed gear bicycle so that one revolution of the pedal is equal to one revolution of the tire
Solution:
Torque T on pedal = F x l = 25 x 0.165 = 4.125 N-m
Rotational impulse = T x t = 4.125 x 1 = 4.125 N-m-s
Initial momentum of wheel = 0 (since it start from rest)
Final momentum of wheel = I x w
Where w = angular speed
I x w = 0.12w
Change of momentum = 0.12w - 0 = 0.12w
Rotational impulse = momentum change
4.125 = 0.12w
w = 4.125/0.12 = 34.375 rad/s
Tangential velocity of wheel = angular speed x radius of wheel
V = w x r = 34.375 x 0.33 = 11.34 m/s
