Answer:
hello your question is incomplete attached below is the missing part
answer : short period oscillations frequency = 0.063 rad / sec
phugoid oscillations natural frequency ( ) = 4.27 rad/sec
Explanation:
first we have to state the general form of the equation
=
where :
comparing the general form with the given equation
= 18.2329
hence the short period oscillation frequency ( ) = 0.063 rad/sec
phugoid oscillations natural frequency ( ) = 4.27 rad/sec
Answer:
IMA = 2.5 metres
EFFICIENCY = 80%
Explanation:
The AMA of a machine is referred to as the Actual Mechanical Advantage of a machine, calculated as the ratio of the output to the input force.
The Ideal Mechanical Advantage is the ratio of the input distance to the output distance.
From the diagram, the input distance which is also the distance moved by effort = 5metres
The load distance (output distance) = 2 metres
IMA = INPUT DISTANCE / OUTPUT DISTANCE
IMA = 5metres / 2 metres = 2.5 meters
Efficiency is the ratio of AMA TO IMA
AMA = 2, IMA = 2.5
EFFICIENCY = AMA / IMA
EFFICIENCY = (2 / 2.5) × 100%= 0.8 × 100%
EFFICIENCY = 80%
Newton's Laws of motion describe the motion of an object based on the applied force
The correct option that gives the relationships between the forces is the the option;
<u> on bat</u> =
<u> on ball</u>
<em>(Either option A or B without the minus symbol before </em><em>, likely typographical error)</em>
<em />
Reason:
Force exerted on the bat by the ball =
Force exerted on the ball by the bat =
Given that the batter hits the ball with the bat, the force exerted by the bat on the ball, , is reacted to by the force of the ball acting on the bat,
According to Newton's third law of motion, action and reaction are equal and opposite. Therefore, at the moment when the ball hits the bat, we have;
<u> on bat</u> =
<u> on ball</u>
<em>Where the force of the bat is high, the ball is accelerated to travel at high speed</em>
