A force of 240 N causes an object to accelerate at 3.2 m/s2. What is the mass of the object? A.75N
B.75 kg
C.0.013 kg
D.768 kg
Which is the answer?

B.75 kg

Explanation:

Given parameters:

Force on the object = 240N

Acceleration of the object = 3.2m/s²

Unknown:

Mass of the object = ?

Solution:

Force is the pull or push on an object. According to Newton's first law; it is mathematically expressed as;

     Force  = mass x acceleration

The unknown here is the mass, simply input the parameters and solve for it;

       240  = mass x 3.2

           mass  =   = 75kg

The mass of the object is 75kg

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

the correct answer in apex is tissue development, i know because i just had this question
