Answer:
The field of view is reduced.
Explanation:
Given that,
The field of view for every resultant magnification like you change objectives from 4 to 10 to 43.
We know that,
Field of view :
When the view is observed at a point in a defined field then these field called field of view.
The normal angle of field of view is 90°.
The formula of field of view is define as,
We can say that,
The field of view is inversely proportional to the magnification.
When magnification is low then field of view will be large.
When magnification is higher then field of view will be small .
According to question,
When the magnification adjust from 4 to 10 to 43, the field of view is reduced.
Hence, The field of view is reduced.
Answer:
0.4 s
Explanation:
The time that the ball is in the air can be found with the next formula:
where is the initial velocity of the ball, in this case:
β is the angle: β = 29.0°
And g is the acceleration of gravity:
Replacing all the values to find t, we have:
Thus, the ball is 0.4s in the air.
Answer:
The value is
Explanation:
From the question we are told that
The angular speed is
The distance between the minimum and maximum external position is
Generally the amplitude of the crank shaft is mathematically represented as
=>
=>
Generally the maximum speed of the piston is mathematically represented as
=>
=>
The acceleration of the air plane is
<u>Explanation:</u>
Given:
The mass of the air plane = 1492.3 kg
Force of each four engine = 1447.5 N
So, the total force of four engines can be calculated as = 4(1447.5) = 5790 N
The force that acts on the object is equal to the product of mass (m) and its acceleration. It can express by the below formula,
The above equation can be written as below to find acceleration,
Now. Substitute the given values, we get,
