The gravitational force on two objects can be determined by the following equation:
Where G is the gravitational constant m1 is mass 1, m2 is the second mass nad r^2 is distance between these objects. Therefore, let m1 = mass of Sun 1.99x10^30 kg, m2= mass of Jupiter 1.90x10^27 kg, r is the average distance between the Sun and Jupiter 7.78x10^11 m. By plugging these values in we have:
F=4.17x10^23 N
The average velocity of Sandy is given by the total distance covered S divided by the total time taken t:
The total distance covered is
while the total time taken is 2 hours + half an hour (for the rest) + 1 hour and half, so
Therefore, the average velocity is
Answer:
0.857 cm
Explanation:
We are given that:
The focal length for a convex lens to be (f) = 1.5cm
The object distance (u) = - 2.0 cm
We are to determine the image distance (v) = ??? cm
By applying the lens formula:
By rearrangement and making (v) the subject of the above formula:
replacing the given values:
v = 0.857 cm
Answer:
in simple harmonic motion, the formula for finding amplitude is:
a = -ω^2 x
where, a=amplitude, ω= angular frequency, x= Displacement
