I am sorry but all I know is that 10. is abruptly. I hope it helps anyways
Answer: 7 kg bowling ball must move with a speed of 2.8 m/s so that it has the same kinetic energy.
Explanation:
Kinetic energy is the energy possessed by a body by virtue of its motion.
![K.E=\frac{1}{2}mv^2](https://tex.z-dn.net/?f=K.E%3D%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
m = mass of object
v= velocity of the object
![K.E=\frac{1}{2}\times 6kg\times (3m/s)^2=27Joules](https://tex.z-dn.net/?f=K.E%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%206kg%5Ctimes%20%283m%2Fs%29%5E2%3D27Joules)
b) for a 7 kg bowl to have kinetic energy of 27 Joules:
![27J=\frac{1}{2}\times 7kg\times v^2](https://tex.z-dn.net/?f=27J%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%207kg%5Ctimes%20v%5E2)
![v^2=7.7](https://tex.z-dn.net/?f=v%5E2%3D7.7)
![v=2.8m/s](https://tex.z-dn.net/?f=v%3D2.8m%2Fs)
Thus 7 kg bowling ball must move with a speed of 2.8 m/s so that it has the same kinetic energy
Both travel in waves caused by vibrations. Both can be reflected refracted, and diffracted.
Answer and Explanation:
FFD is the distance between the film on which the image is obtained and the center of the anode tube. The magnification and resolution of the image depends on the FFd By varying the FFD we can change the magnification and resolution of the image. The standard FFD is about 100 centimeters.
New studies have found that by changing the FFD to 130 cm the radiation dosage reduces while the image quality remains practically the same.
