So the equation used in this problem is ΔX=V0*T+1/2AT^2 the X is the distance, v0 is initial velocity, T is time, and a is acceleration. So when we plug these values it we get: 108= 0•T+1/2•3•T^2,the 0•t disappears, and the 1/2•3 gets us 1.5, so we have 108=1.5T^2, then we divide 108 by 1.5 which gets us 72=t^2, and we then take the square root and get 8.49=T so the answer is 8.49 seconds.
Answer:
g/cm³
Explanation:
From the question given above,
The y-axis is representing mass (g)
The x-axis is representing volume (cm³)
Unit of slope =?
Slope of a graph is simply defined as the change in y-axis divided by the change in x-axis. Mathematically it is expressed as:
Slope = change in y-axis (Δy)/change in x-axis (Δx)
Slope = Δy/Δx
Thus, with the above formula, we can obtain the unit used for measuring the slope as follow:
y-axis = mass (g)
x-axis = volume (cm³)
Slope =.?
Slope = Δy/Δx
Slope = mass (g) /volume (cm³)
Slope = g/cm³
Therefore, the derive unit used for measuring the slope is g/cm³
The new rotational energy of the system(RE) = 
How this is calculated?
- Distance of each astronaut from centre of mass(m)=d/2
- Moment of inertia of system

- So, angular speed,ω =
=
- Rotational energy of system=

where, ω= angular speed

What is rotational energy?
- Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy.
- Looking at rotational energy separately around an object's axis of rotation, the following dependence on the object's moment of inertia is observed

As accurately described by Einstein's theory of relativity, gravity is not necessarily a force, but a consequence of the curvature of space time that is caused by the uneven distribution of mass. But this could be understood more easily through Newton's Law of Universal Motion. The equation is shown below:
F = G(m₁m₂/d²), where
F is the gravitational force
G is called Newton's universal gravitation constant equal to 6.673×10⁻¹¹ N m² kg⁻²
m is the mass of the objects 1
d is the distance between the objects
Basing on the equation, the gravitational force depends on the mass the distance between the objects. So, when you compare the gravitational pull between Earth and moon. you do not need to include the effect of distance because, together. they have the same amount of d. So, it mainly depends on the masses. Since F is directly proportional to m, the greater the mass, the greater is the pull.
So, the answer is: <span>The Earth has more mass than the moon.</span>
