Out of the choices given, the tool that would be best for Diana to use is the light microscope. The correct answer is B.
Answer:2t
Explanation:
Given
Jason throwing watermelon at speed v and it spend t time in air
time to reach max height
![v_f=u_i+at'](https://tex.z-dn.net/?f=v_f%3Du_i%2Bat%27)
0=v-gt'
![t'=\frac{v}{g}](https://tex.z-dn.net/?f=t%27%3D%5Cfrac%7Bv%7D%7Bg%7D)
and time to reach bottom is also t'
t=2t'
![t=2\frac{v}{g}](https://tex.z-dn.net/?f=t%3D2%5Cfrac%7Bv%7D%7Bg%7D)
For guy throws his watermelon at speed 2v
So total time in air will be
![t''=2\frac{2v}{g}](https://tex.z-dn.net/?f=t%27%27%3D2%5Cfrac%7B2v%7D%7Bg%7D)
![t''=4\frac{v}{g}](https://tex.z-dn.net/?f=t%27%27%3D4%5Cfrac%7Bv%7D%7Bg%7D)
t''=2t
Answer:
Explanation:
the net force on the right left is 25 N and is directed upward
the net force on the left one is zero because 200N force act upward and 200N force act downward so both cancel each other and net force is zero
i hope this will help you
Answer:
2.61 atm
Ley de Boyle
Explanation:
= Presión inicial = 0.96 atm
= Presión final
= Volumen inicial = 95 mL
= Volumen final = 35 mL
En este problema usaremos la ley de Boyle.
![\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}\\\Rightarrow P_2=\dfrac{P_1V_1}{V_2}\\\Rightarrow P_2=\dfrac{0.96\times 95}{35}\\\Rightarrow P_1=2.61\ \text{atm}](https://tex.z-dn.net/?f=%5Cdfrac%7BP_1%7D%7BP_2%7D%3D%5Cdfrac%7BV_2%7D%7BV_1%7D%5C%5C%5CRightarrow%20P_2%3D%5Cdfrac%7BP_1V_1%7D%7BV_2%7D%5C%5C%5CRightarrow%20P_2%3D%5Cdfrac%7B0.96%5Ctimes%2095%7D%7B35%7D%5C%5C%5CRightarrow%20P_1%3D2.61%5C%20%5Ctext%7Batm%7D)
La presión ejercida sobre el émbolo para reducir su volumen es de 2.61 atm.
I think the correct answer would be that Charles' law explains why <span>a balloon deflates when the air around it cools. Charles' law is a simplification of the ideal gas law. At constant pressure, volume and temperature have a direct relationship. Hope this helps.</span>
