Answer: The statement is false , if Jupiter and Venus somehow became the same size, Jupiter would still have more mass due to its density and composition and rocks, minerals, and etc.
Explanation:
The question appears to be incomplete.
I assume that we are to find the coefficient of static friction, μ, between the desk and the book.
Refer to the diagram shown below.
m = the mass of the book
mg = the weight of the book (g = acceleration due to gravity)
N = the normal reaction, which is equal to
N = mg cos(12°)
R = the frictional force that opposes the sliding down of the book. It is
R = μN = μmg cos(12°)
F = the component of the weight acting down the incline. It is
F = mg sin(12°)
Because the book is in static equilibrium (by not sliding down the plane), therefore
F = R
mg sin(12°) = μmg cos(12°)
Therefore, the static coefficient of friction is
μ = tan(12) = 0.213
Answer: μ = 0.21 (nearest tenth)
Answer:
57.4 m/s
Explanation:
Component of vectors parallel to the ground = v sin(titha)
= 100×sin35
= 57.4 m/s

Answer:
active galaxies are extremely bright and travel faster than normal galaxies. The mass of active galaxies is confined to a smaller space and they have some activity in their nuclei which produces an enormous amount of energy in a very small volume of space.
