Answer:
Or
2,668,320,000
Explanation:
Potential energy is given as the product of mass, acceleration due to gravity and height.
PE=mgh
Where m is the mass of pyramid, g is acceleration due to gravity and h is height at any point.
In reference to the earth, we substitute h for 34.0 m and g with 9.81 m/s2 then taking m as 8000000000 kg we get that
PE=mgh=8000000*9.81*34.0=2,668,320,000 J
In scientific notafion, this is expressed as
Scientists use models to help explain an idea, visualize hypotheses, and closely examine something (such as an atom).
The calculated total mechanical energy will reduce if the oscillation is not perpendicular to the photogate.
<h3>Mechanical energy at the lowest position of the pendulum</h3>
The mechanical energy at the lowest position of the pendulum is calculated as follows;
<h3>When the direction of the motion changes</h3>
let the velocity of the pendulum = vsin(θ)
when the velocity is perpendicular = vsin(90) = v
At any direction different from perpendicular direction, the mechanical energy reduces by;
Thus, the calculated total mechanical energy will reduce if the oscillation is not perpendicular to the photogate.

Answer:
40X
Explanation:
M=F/f
M=800/20 ( the units cancel each other )
M=40X.
