Answer:
74
Explanation:
28+2*(24-1)= 74
Given:- There are 28 seats in the front row of theater
Number of rows=24
To find:- The number of seats in the last row.
Use the formula to find the 24th term of this sequence.
Also each successive row has two more seats. This difference is same for the whole theater.
So, this forms an arithmetic sequence.
a1=21
D=2
We need to find number of seats in 24th row; which is given by a24
We use the formula for it
Two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.
<h3>What is couple?</h3>
Couple is the pair of force of equal magnitude which acts in opposite direction to each other. The moment of couple is known as the troque, which can be calculate as,
Here, (F) is the magnitude of one of the force and (s) is the perpendicular distance of force acting on axis.
Here, the two opposite forces are given which acts perpendicular to an axis. Now suppose there is the magnitude of both the force (F) is equal and the perpendicular distance from the axis is also same.
Thus, from the above definition of moment of couple, they produce, torque or moment of couple.
Hence, the two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.
