Answer:
Interviewing and observation are two methods of collecting qualitative data as part of research. ... Interviews vary from structured, in which a set list of questions is asked of every interviewee, to unstructured, which is open-ended.
<span>The Earth’s orbit is a nearly circular ellipse.
</span><span>The Sun is located at one of the two focal points.</span>
The Earth moves around the Sun in an orbit that is almost but not quite circular. As Kepler proved in the seventeenth century, the orbit is actually an ellipse. A parameter called the eccentricity (e) defines the degree of departure from a circle. A value of e=0 would indicate a circle whereas a value of e=0.9 would indicate a very elongated ellipse. The eccentricity of the Earth's orbit is currently e=0.0167.
The pair of equal forces that pull a planet and the Sun
toward each other are gravitational forces.
Answer:
x = 1.63 m
Explanation:
mass (m) = 10 kg
μk = 0.3
velocity (v) = 3.1 m/s
Assuming that most of the computers weight is applied on the belt instantaneously, we can apply the constant acceleration equation below
x = 
where a = μk.g , therefore
x = 
/2μk.g
x = (3.1 x 3.1)/(2 x 0.3 x 9.8)
x = 1.63 m
