[#306] A particle moves along a straight line such that distance âxâ traversed in âtâ seconds is given by x = t 2 (t + 1), the acceleration of the particle, will be
Correct Answer
(D) 6t + 2
[#307] A Seconds pendulum executes
Correct Answer
(B) 1.0 beat per second
Explanation
Solution: The correct answer is Option B: 1.0 beat per second Here's why: A seconds pendulum is defined as a pendulum that takes exactly one second to swing in one direction. This means it takes one second to complete half of its full swing (from one extreme point to the other). A "beat" refers to one such swing . Since it takes 1 second for one beat, it means it has 1.0 beat per second.
[#308] The forces which meet at one point and have their lines of action in different planes are called
Correct Answer
(B) Non-coplanar concurrent forces
[#309] The centre of gravity of a quadrant of a circle lies along its central radius at a distance of
