Answer: The internal heat energy of the boat heat engine, metamorphoses into mechanical workdone that causes the boat to move.
Explanation: First law of thermodynamics tells us that energy cannot be created nor destroyed, it can only be transformed from one form to another.
The internal heat energy of the boat heat engine, metamorphoses into mechanical workdone that causes the boat to move.
According to the second law of thermodynamics which state that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases. Differences in temperature, pressure, and density tend to even out horizontally after a while
Answer:
1438.4 N
Explanation:
Applying,
F = kqq'/r²................... Equation 1
Where F = Electrostatic force on the balloons, k = coulomb's constant, q = charge on the first balloon, q' = charge on the second balloon, r = distance between the two ballons.
From the question,
Given: q = q' = 4.0×10⁻⁵ C, r = 0.1 m
Constant: k = 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = ( 4.0×10⁻⁵×4.0×10⁻⁵×8.99×10⁹)/0.1²
F = 14.384/0.01
F = 1438.4 N
We know
<h3>☆Mass on moon =1/6 on earth</h3>
Explanation:
u=0, v=?, a=5m/s², t=8sec
So, by the formula,
v=u+at
v=0+5×8
v=40m/s.
hope this helps you .
You can describe the location of any event ... past, present, or future... with
four numbers, representing the four dimensions of the universe we live in.
The numbers are the three space coordinates of the event ... the 'x', 'y', and 'z'
of its physical location ... and the 't' of its location in time.
