Explanation:
a buffer is a chemical substance that maintains a relatively constant pH
Answer:
The voltage is 2.114 V.
Explanation:
Given that,
Mass of both weights = 225 gm
Transducer sensitivity = 0.5 V/N
The first mass is located 20∘ north of east, the second mass is located 20∘ south of east,
We need to calculate the net equivalent force
Using formula of force
![F_{3}=m_{1}g\cos\theta+m_{2}g\cos\theta](https://tex.z-dn.net/?f=F_%7B3%7D%3Dm_%7B1%7Dg%5Ccos%5Ctheta%2Bm_%7B2%7Dg%5Ccos%5Ctheta)
![F_{3}=2mg\cos\theta](https://tex.z-dn.net/?f=F_%7B3%7D%3D2mg%5Ccos%5Ctheta)
Put the value into the formula
![F_{3}=2\times0.225\times10\cos20^{\circ}](https://tex.z-dn.net/?f=F_%7B3%7D%3D2%5Ctimes0.225%5Ctimes10%5Ccos20%5E%7B%5Ccirc%7D)
![F_{3}=4.228\ N](https://tex.z-dn.net/?f=F_%7B3%7D%3D4.228%5C%20N)
We need to calculate the voltage
Using formula of voltage
![Voltage =sensitivity\times F_{3}](https://tex.z-dn.net/?f=Voltage%20%3Dsensitivity%5Ctimes%20F_%7B3%7D)
Put the value into the formula
![Voltage=0.5\times4.228](https://tex.z-dn.net/?f=Voltage%3D0.5%5Ctimes4.228)
![Voltage =2.114\ V](https://tex.z-dn.net/?f=Voltage%20%3D2.114%5C%20V)
Hence, The voltage is 2.114 V.

Explanation:
A projectile is an object upon which the only force is gravity. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity. Due to the absence of horizontal forces, a projectile remains in motion with a constant horizontal velocity.
