The force of gravity is the force with which massively large objects such as the earth attracts another object towards itself. All objects of the earth exert a gravity that is directed towards the center of the earth. Therefore, the force of gravity of the earth is equal to the mass of the object times acceleration due to gravity.
<span>F = ma </span>
<span>4.9N = m (9.8 m/s^2), note that N (newtons) = kg-m/s^2 </span>
m = 0.5 kg
<span>The mass of the object is 0.5kg.</span>
i’m pretty sure it is B i took thsi a while ago
Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.
Quantitative data is defined as the data that can be counts in number or can be measured in numbers. There are two main types of quantitative data : discreate data and the continuous data. examples are age , date, distance , weight etc. so, the countable and measurable quantities in numbers is quantitative data. Wavelength here is measured in numbers . so, wavelength is the quantitative data.
Thus, Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.
