Answer : The density of an object is 0.93 g/mL
Explanation : Given,
Mass of an object = 3.8 g
Initial volume = 4.5 mL
Final volume = 8.6 mL
First we have to calculate the volume of an object.
Volume of an object = Final volume - Initial volume
Volume of an object = 8.6 mL - 4.5 mL
Volume of an object = 4.1 mL
Now we have to calculate the density of an object.
Formula used:
![\text{Density}=\frac{\text{Mass of an object}}{\text{Volume of an object}}](https://tex.z-dn.net/?f=%5Ctext%7BDensity%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20an%20object%7D%7D%7B%5Ctext%7BVolume%20of%20an%20object%7D%7D)
Now putting all the given values in this formula, we get:
![\text{Density}=\frac{3.8g}{4.1mL}](https://tex.z-dn.net/?f=%5Ctext%7BDensity%7D%3D%5Cfrac%7B3.8g%7D%7B4.1mL%7D)
![\text{Density}=0.93g/mL](https://tex.z-dn.net/?f=%5Ctext%7BDensity%7D%3D0.93g%2FmL)
Therefore, the density of an object is 0.93 g/mL
A plant needs Sunlight, water, and carbon dioxide to produce ATP from photosynthesis.
Answer:
8.125 atm
Explanation:
Hello,
Boyle's law states that at constant temperature:
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
In this case:
![P_1=1 atm, V_1=27.3L, V_2=3.36L](https://tex.z-dn.net/?f=P_1%3D1%20atm%2C%20V_1%3D27.3L%2C%20V_2%3D3.36L)
Solving for
:
![P_2=\frac{P_1V_1}{V_2}=\frac{1atm*27.3L}{3.36L}\\P_2=8.125atm](https://tex.z-dn.net/?f=P_2%3D%5Cfrac%7BP_1V_1%7D%7BV_2%7D%3D%5Cfrac%7B1atm%2A27.3L%7D%7B3.36L%7D%5C%5CP_2%3D8.125atm)
Best regards!

Because if you follow a fitness plan you can get done a lot of stuff that you can't without a plan so like you make a plan of what you are going to do instead of just doing random fitness stuff
