The amount of matter contained by an object is called mass.
A. mass
<u>Explanation:</u>
Mass is fundamentally a property of any physical amount and it is additionally the estimation of the resistance from the acceleration when force is applied on an object. The mass equals the quality of the gravitational force on a body.
Mass, in material science, the quantitative proportion of idleness, a crucial property of all matter. The greater the mass of a body, the littler the change created by an applied power. The mass of an object can be portrayed by its capacity to oppose a given power (we once in a while call this a body's inertial mass and subsequently mass is personally connected with the idea of inertia).
This is a straightforward result of Newton's second law where the power F, on a body is equivalent to the mass m, times the speeding up an, it encounters, ie:
F=ma or m=F/a
Mass of an object can not be zero but weight can be zero. The mass and weight of an object are different things.

Answer:
Δt = 0.315s
Explanation:
To calculate the time difference, in which both fans hear the batterstrike, you first calculate the time which takes the sound to travel the distances to both fans:
d1: distance to the first fan = 18.3 m
d2: distance to the second fan = 127 m
vs: speed of sound = 345 m/s
You replace the values of the parameters to calculate t1 and t2:
The difference in time will be:
Hence, the time difference between hearing the sound at the location s of both fans is 0.315s
<h2>
Option B is the correct answer.</h2>
Explanation:
Period of a spring mass arrangement is given by
where m is mass and k is spring constant.
So period of spring mass arrangement is independent of amplitude of motion.
Here amplitude changes from A to 2A.
Period for amplitude A is given by T.
Since period remains same for amplitude 2A also, the period is T.
Option B is the correct answer.
