KE = 8887.5 J
<h3>Further explanation</h3>
Given
speed = 15 m/s
weight = 79 kg
Required
KE-Kinetic energy
Solution
Energy is the ability to do work
Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:
Input the value :
KE = 1/2 x 79 kg x 15² m/s²
KE = 8887.5 J
In this question, we know that mass= 10 kg = 10 x 1000 = 10,000 g
Distance = 1 m and Time = 0.5 s
Power = Force x Velocity
Velocity = Distance / Time = 1 m / 0.5 s = 2 m/s
So, Power = Force x (Distance / Time)
But Force= Mass x Acceleration due to gravity (g)
So, Force = 10 kg x 9.8 m/s
= 98
Therefore, Power =Force x Velocity= 98 x 2 =
196 W
Electrical energy to thermal energy
Red: The red parts will stay the same
The blue parts will turn black - there is no red in blue
The white parts will turn red - there is red in white
Blue: The blue parts will stay the same
The red parts will turn black - there is no blue in red
The white parts will turn blue - there is blue in white
Answer:
A siphon is a tube that makes use of the potential energy of fluid at an elevated level to transfer the fluid to a lower level, due to pressure differences between the inlet and the outlet points of the tube, such that the pressure at the outlet is higher than the pressure at the inlet
The pressure energy is converted into velocity (kinetic) energy, and therefore, in other to increase the flow rate through the tube of a siphon, with constant diameter, the level of the fluid in the container at the inlet (supply) of the siphon is raised higher than the level at the outlet receiving) container or the outlet point of the siphon tube
The larger the difference between the inlet and outlet levels, the faster the transfer of fluid by the siphon
