Answer:
The answer to your question is 5.5 x 10¹² kg/km³
Explanation:
Data
density = rho = X
mass = 5.94 x 10²⁴ kg
volume = 1.08 x 10¹² km³
Process
To solve this problem use the density formula and simplify it to find the result.
Formula
density = 
Substitution
density = 
Simplification and result
density = 5.5 x 10¹² kg/km³
Neglecting air resistance, the acceleration of the ball is
the acceleration of gravity ... 9.8 m/s² downward.
It doesn't matter what you toss, what it's mass is, what it weighs,
what color it is, how much it cost, what its shape or size is, how
fast you toss it, in what direction, or how long it's in the air.
Its horizontal acceleration is zero and its vertical acceleration
is 9.8 m/s² downward, from the moment it leaves your hand
until the moment somebody catches it or it hits the ground.

Answer:
The wave velocity is 1.3736
Explanation:
A plot of inverse of wavelength (λ) versus frequency (f), can be analyzed as follows;
The vertical axis will be 1/λ and the horizontal axis will be f
slope = (Δ1/λ)/(Δf)
= 1/(fλ)
∴ 1/(fλ) = 0.728
From wave equation, V = fλ
where;
V is the wave velocity
f is the frequency of the wave
λ is the wavelength
1/(fλ) = 0.728
1/(V) = 0.728
V = (0.728)⁻¹
V = 1.3736
Therefore, the wave velocity is 1.3736
Answer:
v = 1.7 m/s
Explanation:
Given that,
Initial velocity of the object, u = 1 m/s
Acceleration of the object, a = 1 m/s²
We need to find the velocity of the object after moving 1 m. Let v be the velocity. Using third equation of kinematics to find it i.e.
So, the final velocity of the object is 1.7 m/s.
