According to Newton's second law of motion, the acceleration of a body is directly proportional to the force acting on the body and inversely proportional to its mass. The formula for this law is
F=ma
=4000kg * 2m/s 2 =8000N
Answer:
i) Telescopes can be used to view far distant objects but the human eye can't view far distant objects.
ii) Telescopes uses two convex lenses producing a magnified image while the human eye only possesses one convex lens (image seen are smaller than that viewed under telescopes)
Explanation:
The telescopes can be used to view far distant objects due to their presence of two convex lenses. The two convex lenses are the objective lens (lens closer to object) and the eye piece lens (lens closer to eye). The object to be viewed forms an intermediate image first before the final image is seen using the eye piece lens.
The human eye only possess one convex lens and as such cannot view far ranged objects.
Answer:
The correct option is;
c. 22.6
Explanation:
The given parameters are;
The hypotenuse of the vector = 32
The angle of the vector = 45°
Therefore, the vector component in the y-axis is given as follows;
![v_y = v \times sin(\theta)](https://tex.z-dn.net/?f=v_y%20%3D%20v%20%5Ctimes%20sin%28%5Ctheta%29)
Substituting the values from the question gives;
![v_y = 32 \times sin(45^{\circ}) \approx 22.6](https://tex.z-dn.net/?f=v_y%20%3D%2032%20%5Ctimes%20sin%2845%5E%7B%5Ccirc%7D%29%20%5Capprox%2022.6)
The vector component in the y-axis,
, is approximately 22.6.
