A column of soldiers, marching at 121 steps per minute, keep in step with the beat of a drummer at the head of the column. It is

observed that the soldiers in the rear end of the column are striding forward with the left foot when the drummer is advancing with the right. What is the approximate length of the column? (Take the speed of sound to be 343 m/s.)

There’s a first “clump”/drum beat every half second. That clump will travel about 170m in half a second. Someone 170m away would do their “clump” as the second “clump” was taking place. I think. <span> </span>

A vehicle of known mass accelerates along a straight path. According to Newton's second law of motion, what caused this accelera
Naily [24]

The answer would be:

C. An unbalanced force has acted on the vehicle.

The presence of an unbalanced force will accelerate an object, the second law of motion dictates this (Although not explicitly). Lets knock out the rest of the choices.

If a balance force acted on the vehicle, then the vehicle would be at rest. The mass of the vehicle did not change (Unless it falls apart, which I doubt). The direction of the vehicle does not change and it will only do so if another force and a stronger one at that will counteract the current net force acting on the vehicle.

Hope you got your answer here, although you did not ask for an explanation, maybe this will help you figure some of the other questions you have on your own.

A pendulum that has a period of 2.67000 s and that is located where the acceleration due to gravity is 9.77 m/s2 is moved to a l
zalisa [80]

Answer:

Explanation:

Expression for time period of pendulum is given as follows

T=2\pi\sqrt{\frac{l}{g} }

where l is length of pendulum and g is acceleration due to gravity .

Putting the given values for first place

2.67=2\pi\sqrt{\frac{l}{9.77} }

Putting the values for second place

T=2\pi\sqrt{\frac{l}{9.81} }

Dividing these two equation

\frac{T}{2.67} =\sqrt{\frac{9.77}{9.81} }

T = 2.66455 s.
