Answer: 24
Explanation:
Given the following equation:
![g=3n](https://tex.z-dn.net/?f=g%3D3n)
Where
is the number of mushrooms in a pizza and
the number of pizzas.
If we know the restaurant will make 8 pizzas (
), then:
![g=3(8)](https://tex.z-dn.net/?f=g%3D3%288%29)
This is the needed number of mushrooms for 8 pizzas
Answer:
0.30581
0.24464
Explanation:
= Coefficient of static friction
= Coefficient of kinetic friction
= 75 N
= 60 N
Normal force
![F_n=mg\\\Rightarrow F_n=25\times 9.81\\\Rightarrow F_n=245.25\ N](https://tex.z-dn.net/?f=F_n%3Dmg%5C%5C%5CRightarrow%20F_n%3D25%5Ctimes%209.81%5C%5C%5CRightarrow%20F_n%3D245.25%5C%20N)
Frictional force
![F_f=\mu_sF_n\\\Rightarrow \mu_s=\frac{F_f}{F_n}\\\Rightarrow \mu_s=\frac{75}{245.25}\\\Rightarrow \mu_s=0.30581](https://tex.z-dn.net/?f=F_f%3D%5Cmu_sF_n%5C%5C%5CRightarrow%20%5Cmu_s%3D%5Cfrac%7BF_f%7D%7BF_n%7D%5C%5C%5CRightarrow%20%5Cmu_s%3D%5Cfrac%7B75%7D%7B245.25%7D%5C%5C%5CRightarrow%20%5Cmu_s%3D0.30581)
The coefficient of static friction is 0.30581
Kinetic force
![F_k=\mu_kF_n\\\Rightarrow \mu_k=\frac{F_k}{F_n}\\\Rightarrow \mu_s=\frac{60}{245.25}\\\Rightarrow \mu_s=0.24464](https://tex.z-dn.net/?f=F_k%3D%5Cmu_kF_n%5C%5C%5CRightarrow%20%5Cmu_k%3D%5Cfrac%7BF_k%7D%7BF_n%7D%5C%5C%5CRightarrow%20%5Cmu_s%3D%5Cfrac%7B60%7D%7B245.25%7D%5C%5C%5CRightarrow%20%5Cmu_s%3D0.24464)
The coefficient of kinetic friction is 0.24464
Boyle's law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 4l , the pressure is 720 kpa (kilopascals). What is the pressure when the volume is 10l ?
Answer:
I have examined the different parts of blub and I assume the answer is (D)T and U
