Force equals mass*distance
F = ma
Given m = 10 kg, F = 30 N
30 = 10a
30/10 = a
3 = a
The wagon's acceleration is 3 m/s^2
Answer:
37.42 m/s
Explanation:
We know that apparent frequency, 
is given by
where f is the given frequency in this case 392, V is the speed of sound in air which is given as 343 and 
is the speed of car which is unknown, \bar f is given as 440 Hz
The term used to describe the quantity of matter that a body possesses is mass.
Kepler's laws were enunciated to model in a mathematical way the movement of the planets in their respective orbits around the Sun.
There are three laws of Kepler.
In particular, Kepler's first law states the following:
"All the planets move around the Sun describing elliptical orbits, the Sun is in one of the foci of the ellipse."
Answer:
Kepler's 1st law of planetary motion states that the planets have an elliptical orbit, with the Sun at one focal point of the ellipse.
a. 1st law
