Answer:
Explanation:
Conservation of momentum
Initial momentum is zero as both gun and bullet are motionless in the frame of reference before firing.
0 = 0.012(1500.0) + 4.0v
v = - 4.5 m/s
Must be a rail gun as the fastest powder driven bullets are moving at roughly half the speed described.
Answer
Correct Answer is D( Marie Sklodowska-Curie)
Explanation
Marie Curie is known for her contributions such as the discovery of Radium and other key elements help us out every day, especially when getting an x-ray.
Marie Curie worked with her husband Pierre Curie and received the Nobel Prize in 1903 for their research of discovery of radium. Marie curie and Pierre Curie published a research paperin which they mentioned the processes they have used to isolate radium. Marie Curie works described the effects of radium on living organisms. Marie Curie showed it could damage tissue, and this discovery was used against cancer and other diseases.
Answer:
<h3>The maximum possible torque is τ =
![4.8 \times 10^{-3}](https://tex.z-dn.net/?f=4.8%20%5Ctimes%2010%5E%7B-3%7D)
N .</h3>
Explanation:
Given :
No. of turns ![N = 52.5](https://tex.z-dn.net/?f=N%20%3D%2052.5)
Radius of circular coil
m
Magnetic field
T
Current
A
For maximum torque,
τ = ![BIAN \sin \theta](https://tex.z-dn.net/?f=BIAN%20%5Csin%20%5Ctheta)
Where
area of coil
=
For maximum possible torque
,
τ = ![52.5 \times 26.3 \times 10^{-3} \times 0.465 \times 75.39 \times 10^{-4}](https://tex.z-dn.net/?f=52.5%20%5Ctimes%2026.3%20%5Ctimes%2010%5E%7B-3%7D%20%5Ctimes%200.465%20%5Ctimes%2075.39%20%5Ctimes%2010%5E%7B-4%7D)
τ =
N
The problem stated above is a simple conversion problem. To be able to convert from one unit to another unit, we should know the relation of the units. In this case, we need to know the relation of megabytes and gigabytes. From literature, it is known that 1 gigabyte is equal to 1000 megabyte so we use this. We converts as follows:
4.7 GB ( 1000 MB / 1 GB ) = 4700 MB
