In a series circuit, as light bulbs are added the voltage at the battery remains the same but the current at the battery decreases.
The general effort force equation for block and tackle to raise or pull a load can be expressed as
<span><span>S=<span>F/<span>μn</span></span></span>
</span>
where
<span>S
</span> is the effort force,
<span>F
</span> is the load force (often the weight of the object to be moved),
<span>μ
</span> is the mechanical efficiency of the system (1 in an ideal, massless, frictionless system of pulleys), and
<span>n
</span> is the number of ropes between the sets of pulleys.
Nitric acid (NHO3) because plants need nitrogen to survive, hope this helped.
Answer:
v = 6.95 m/s
Explanation:
Given that,
A diver is on a board 1.80 m above the water, s = 1.8 m
The initial speed of the diver, u = 3.62 m/s
Let v is the speed with which she hit the water. It will move under the action of gravity. Using the equation of motion as follows :
![v^2-u^2=2gs\\\\v=\sqrt{u^2+2gs} \\\\v=\sqrt{(3.62)^2+2(9.8)(1.8)} \\\\v=6.95\ m/s](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2gs%5C%5C%5C%5Cv%3D%5Csqrt%7Bu%5E2%2B2gs%7D%20%5C%5C%5C%5Cv%3D%5Csqrt%7B%283.62%29%5E2%2B2%289.8%29%281.8%29%7D%20%5C%5C%5C%5Cv%3D6.95%5C%20m%2Fs)
So, she will hit the water with a speed of 6.95 m/s.
