having into account that the total time spent in air till the cap came to her hands is Ttotal=2*t
where t is the time which the cap spent to reach the heighest point or the maximun height. so;
Ttotal=2second
t=1sec
we then replace t into the equation(1);
this is the initial velocity with which the cap was thrown

Answer:
The energy stored in the capacitor quadruples its original value.
Explanation:
The energy stored in a capacitor is given by the equation
![U=\frac{1}{2}CV^2](https://tex.z-dn.net/?f=U%3D%5Cfrac%7B1%7D%7B2%7DCV%5E2)
where
C is the capacitance
V is the voltage across the plates
The capacitance, C, depends only on the properties of the capacitor, so it does not change when the voltage applied is changed.
Instead, in this problem the voltage applied is doubled:
V' = 2V
So the new energy stored is
![U'=\frac{1}{2}C(2V)^2=4(\frac{1}{2}CV^2)=4U](https://tex.z-dn.net/?f=U%27%3D%5Cfrac%7B1%7D%7B2%7DC%282V%29%5E2%3D4%28%5Cfrac%7B1%7D%7B2%7DCV%5E2%29%3D4U)
so, the energy stored has quadrupled.
150kmp miles to the second power add all together them together then you get 46 to the 3rd ad 104
<span>The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV.</span>
