In position-time graphs, the slope represents speed, and the y-intercept at a given time represents distance.
(A), (C) and (E) only
(A) and (E) only
(B) and (E) only
(A), (C) and (D) only
The slope of A is given as:
\( \text{slope}_A = V_A \)
The slope of B is given as:
\( \text{slope}_B = V_B \)
Since:
\( \text{slope}_B > \text{slope}_A \)
It follows that:
\( V_B > V_A \)
As velocity (\( V \)) is inversely related to time (\( t \)) for a given distance:
\( t_B < t_A \)
The final answer is: (A) and (E) only.
The angle of elevation of the top P of a vertical tower PQ of height 10 from a point A on the horizontal ground is 45°, Let R be a point on AQ and from a point B, vertically above R, the angle of elevation of P is 60°. If
\(∠BAQ = 30°\)
, AB = d and the area of the trapezium PQRB is α, then the ordered pair (d, α) is :
