A simple pendulum fixed in a car has a time period of 4 seconds when the car is moving uniformly on a horizontal road

Monjur Alahi

A simple pendulum fixed in a car has a time period of 4 seconds when the car is moving uniformly on a horizontal road. When the accelerator is pressed, the time period changes to 3.99 seconds. Making an approximate analysis, find the acceleration of the car.

Hi Princy Meshram, We know from Period equation that the period of oscillation of a simple pendulum is T = 2π√ L/g.
Where,
    T is the period in seconds (s)
    π is the Greek letter pi and is approximately 3.14
    √ is the square root of what is included in the parentheses
    L is the length of the rod or wire in meters or feet
    g is the acceleration due to gravity (9.8 m/s² or 32 ft/s² on Earth)

A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.

Frequency of oscillations is the number of oscillations of a vibrating object per second. Therefore frequency is = 40 vibrations /4 seconds= 10 Hertz.  Time period is the time required to...

A car accelerates on a horizontal road due to the force exerted by (a) the engine of the car

(d) the road. Explanation: The car pushes the ground in the backward direction and according to the third law of motion, reaction force of the ground in the forward direction acts on...

A wheel starting from rest is uniformly accelerated at 4 rad/s 2 for 10 seconds.It is allowed to rotate uniformly for the next 10 seconds

Theta=wt+1/2alpha Tsq. By this we will get Theta=200. For first 10 and last 10 sec theta will be same therefore =400. And for 10 sec of middle is alpha ×100= 400. Total =400+400=800rad

Swapnil, Aakash and Vinay begin to jog around a circular stadium. They complete one lap in 36 seconds, 48 seconds and 42 seconds

(c) They will be together at the starting point after the L.C.M of 36, 48 and 42 L.C.M. of 36, 48, 42 = 1008 seconds
