Answer:
495.5 Joules
Explanation:
Given data
Mass= 10kg
Height= 5meters
g= 9.81m/s^2
Yes the rock will possess potential energy before it hits the ground
The potential energy is expressed as
PE=mgh
substitute
PE= 10*9.91*5
PE= 495.5 Joules
Geosphere. The geosphere includes the geology that makes up the earth. The crust, mantle, asthenosphere, and core are all included.
Answer:
the answers the correct one is cη
Explanation:
In this simple pendulum experiment the student observes a significant change in time between each period. This occurs since an approximation used is that the sine of the angle is small, so
sin θ = θ
with this approach the equation will be surveyed
d² θ / dt² = - g / L sin θ
It is reduced to
d² θ / dt² = - g / L θ
in which the time for each oscillation is constant, for this approximation the angle must be less than 10º so that the difference between the sine and the angles is less than 1%
The angle is related to the height of the pendulum
sin θ = h / L
h = L sin θ.
Therefore the student must be careful that the height is small.
When reviewing the answers the correct one is cη
Answer:
t = 1964636.542 sec
Explanation:
Given data:
sphere diameter is 10 mm
Density is 1150 kg/m^3
viscosity 105 N s/m^2
We knwo that time taken by sphere can be calculated by following procedure
Solving for du
