Answer:
14.4kJ
Explanation:
Work = Force x distance
W × h = mgh
Given that,
mass m, = 59.5kg
acceleration due to gravity = 9.8m/s^2
height ,h = 16.2cm
convert to m is 0.162m
How much work = m x g x h
height is 0.162 x 152 steps
h = 24.624m
work = 59.5 x 9.8 x 24.624
= 14,358.25Joule
= 14.4kJ
Answer:
Yes, a sled has inertia while sitting still.
Explanation:
From Newton's law of inertia, an object at rest will remain at rest unless it is acted upon by an external force. The reason the object will remain at rest unless an external force acts is because of inertia. Inertia means the resistance of an object to motion.
Thus, a sled hammer at rest will remain at rest unless it is acted upon by an external force. So we can conclude that it has Inertia.
Answer:
I think it is the Federal Pell Grant Program.
Explanation:
A. Condensation
Hope this helps!!!
The conservation of the mass of fluid through two sections (be they A1 and A2) of a conduit (pipe) or current tube establishes that the mass that enters is equal to the mass that exits. Mathematically the input flow must be the same as the output flow,
The definition of flow is given by
Where
V = Velocity
A = Area
The units of the flow of flow are cubic meters per second, that is to say that if there is a continuity, the volume of input must be the same as that of output, what changes if the sections are modified are the proportions of speed.
In this way
