Answer:
<h3>2,321.62Joules</h3>
Explanation:
The formula for calculating workdone is expressed as;
Workdone = Force * Distance
Get the force
F = nR
n is the coefficient of friction = 0.5
R is the reaction = mg
R = 46 ( 9.8)
R = 450.8N
F = 0.5 * 450.8
F = 225.4N
Distance = 10.3m
Get the workdone
Workdone = 225.4 * 10.3
Workdone = 2,321.62Joules
<em>Hence the amount of work done is 2,321.62Joules</em>
Answer: In convection, there is a transfer of heat due to the bulk movement of molecules within the fluid. It affects our atmosphere, layers of earth and our ocean due to the temperature difference.
Explanation:
Convection is a transfer of heat due to bulk movement of molecules within the fluid.
Convection affects our atmosphere. There is a temperature difference in the atmosphere. Warmer air rises up in compare to the cooler air.
Convection affects our layers of earth. It is limited to troposphere. Due to the high transmission of clear sky to bulk incident energy from sun, troposphere is subjected to convection.
Convection affects our oceans. There will be temperature difference in the ocean water. When the water of ocean heats up then it becomes less dense.
Answer: Mathematical Model
Explanation:
Took the test
<span>Nodes are points along the medium that appear to be standing still. They are points on a standing wave that has no displacement from the rest position.
Antinodes are the opposite of nodes. Those are</span> points that undergo the maximum displacement.
<span>At the nodes the destructive interference occurs</span> . For example <span>a crest of one wave meets a trough of a second wave</span> , or a half-crest of one wave meets a half-trough of a second wave...
Answer:
All three pendulum will attain same velocity
Explanation:
All three pendulum will attain same velocity irrespective of their mass difference in isolated system (means where air drag are negligible) and at same length
As you know when velocity is calculated we can not take mass into account.
