The blu-ray standard that defines rewritable disks is BD-RE which stands for Blu-ray Disc Recordable.
<h3>
What is BD-RE?</h3>
BD-RE stands for Blu-ray Disc Recordable and it refers to two direct to disc optical disc recording technologies that can be recorded on to a Blu-ray-based optical disc with an optical disc recorder.
Thus, the blu-ray standard that defines rewritable disks is BD-RE which stands for Blu-ray Disc Recordable.

Answer:
(b) 2.40 x
kg/s
Explanation:
Given that: Total mass of the rocket = 3.003 x
kg
acceleration of the rocket = 36.0 m![s^{-2}](https://tex.z-dn.net/?f=s%5E%7B-2%7D)
speed of the exhausted gases = 4.503 x
m/s
Rate at which rocket was initially burning fuel = ![\frac{mass}{time}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Btime%7D)
But,
time = ![\frac{velocity}{acceleration}](https://tex.z-dn.net/?f=%5Cfrac%7Bvelocity%7D%7Bacceleration%7D)
= ![\frac{4.503*10^{3} }{36.0}](https://tex.z-dn.net/?f=%5Cfrac%7B4.503%2A10%5E%7B3%7D%20%7D%7B36.0%7D)
= 125.0833 s
So that;
Rate at which rocket was initially burning fuel = ![\frac{3.003*10^{5} }{125.0833}](https://tex.z-dn.net/?f=%5Cfrac%7B3.003%2A10%5E%7B5%7D%20%7D%7B125.0833%7D)
= 2400.8001
= 2.40 x
kg/s
Therefore, the initial rate at which the rocket burn fuel is 2.40 x
kg/s.
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.
