An example of an energy conversion that produces an unwanted form of energy is mixing acids with water.
Given; Mass m = 65.0 Kg; acceleration a = 1.25 m/s²
Required: Force F = ?
Formula: F =ma
F = (65.0 Kg)(1.25 m/s²)
F = 81.25 N
Answer:
i just need to push harder
Explanation:
the harder you push, the more the door leans on the other side. newtons law i think
Answer:
The answer is below
Explanation:
Charlee's law states that the volume of a gas is directly proportion to the temperature of the gas at constant pressure. That is:
V = kT, where V = volume and T = temperature, k = constant. Therefore:
V / T = k
![\frac{V_1}{T_1}=\frac{V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BT_1%7D%3D%5Cfrac%7BV_2%7D%7BT_2%7D)
Given that: ![V_1=3\ m^3, T_1=20^oC=(20 + 273)K=293\ k,T_2=60^oC=(60 + 273)K=333\ k.\\\\\frac{V_1}{T_1}=\frac{V_2}{T_2}\\\\\frac{3}{293}=\frac{V_2}{333} \\\\V_2=\frac{3}{293}*333\\\\V_2=3.41\ m^3\\](https://tex.z-dn.net/?f=V_1%3D3%5C%20m%5E3%2C%20T_1%3D20%5EoC%3D%2820%20%2B%20273%29K%3D293%5C%20k%2CT_2%3D60%5EoC%3D%2860%20%2B%20273%29K%3D333%5C%20k.%5C%5C%5C%5C%5Cfrac%7BV_1%7D%7BT_1%7D%3D%5Cfrac%7BV_2%7D%7BT_2%7D%5C%5C%5C%5C%5Cfrac%7B3%7D%7B293%7D%3D%5Cfrac%7BV_2%7D%7B333%7D%20%20%20%20%5C%5C%5C%5CV_2%3D%5Cfrac%7B3%7D%7B293%7D%2A333%5C%5C%5C%5CV_2%3D3.41%5C%20m%5E3%5C%5C)
The new volume is 3.41 m³. That is it expands by 0.41 m³
Answer:
PE=0
Explanation:
If the tank is on the ground, there is 0 height which means the equation of PE=mh will be PE=12543(0)=0, hope this helps!
