Explanation:
6. Converge or come together
7. convex
Answer:
a) The strength of gravity decreases if one moved away from Jupiter
b) The strength of gravity increases if one fell into Jupiter
Explanation:
The gravitational attraction is given by Newton law of gravitation as follows;
Where;
G = The universal gravitational constant = 6.67408 × 10⁻¹¹ m³/(kg·s²)
M = The mass of Jupiter
m = The mass of the nearby body
R = The distance between the centers of Jupiter and the body
From the equation, we have that the gravitational strength varies inversely with the square of the separation distance between two bodies
Therefore, as one moves away, R increases, and the strength of gravity reduces
Similarly as the body falls into Jupiter, R, reduces the gravitational strength increases.
It will move in the direction you pushed it, but it will go at a certain velocity
Answer:
Q
Explanation:
To know which symbol defines the wavelength, we must know the definition of wavelength.
Wavelength can be defined as the distance between two successive crests (i.e the highest part) or troughs (the lowest part) of a wave.
Considering the diagram given above, Q shows the distance between two successive crests (i.e the highest part) of the wave. Therefore, Q is the wavelength of the wave given in the diagram above.
Answer:
percentage by volume of the solute = 45%
Explanation:
The percentage by volume of the solute in a solution is the percentage of the volume of the solute as against the overall volume of the solution.
In this example,
volume of solution = 300mL
volume of solute = 135mL
% volume of solute = (volume of solute ÷ volume of solution) × 100
= (135 ÷ 300) × 100
= 0.45 × 100 = 45%
∴ percentage by volume of the solute = 45%
