Answer: The acceleration results if a net force of 4F acts on a mass of 6m is 2/3a.
Explanation:
Force exerted on an object can be defined as a pull or a push on an object which leads to it's displacement. Force is taken to be a vector quantity because it has both magnitude and direction. The formula which can be used to determine force exerted on an object in physics is:
F= mass( kg) × acceleration( m/ s²)
Acceleration is defined as the rate at which the velocity of an object changes. From the formula of force given above it can be determined by making it the subject of formula. Therefore acceleration= Force/ mass.
From the question,
Force= 4F
Mass= 6m
Therefore acceleration= F/m
= 4/6
Acceleration= 2/3a
Answer:
42.4 Npa
Explanation:
Explanation is attached in the picture below
2 electrons. electrons are negative, protons are positive. if it is electrically neutral, there must b the same Amt of them so they can cancel out
Answer:
average velocity at the inlet = 3.66 m/s
Explanation:
given data
discharge Q = 25 ft³
/min = = 0.417 ft³
vacuum cleaner = 1 in by 5 in = ft
solution
we know discharge that is express as
Q = Area × Velocity .............1
put here value and we will get average velocity at the inlet
average velocity at the inlet =
average velocity at the inlet = 3.66 m/s
