Answer:
SI units are interrelated in such a way that one unit is derived from other units without conversion factors. ... SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data without vocabulary confusion.
When he <span>determined that the drop time was inversely proportional to the horizontal velocity, the answer for it would be </span>Bob's conclusion was right because the data points were connected. The connection of the x and y axis varied because it is inversely proportional.
Exactly the same
Explanation:
Objects looks exactly the same when viewed through a transparent object. A transparent body allows light to pass through completely. Therefore, the image formed will completely resemble that of the object to be viewed.
Examples are air, glass, pure water.
A translucent body partially allows light to pass through it. Most times, the image is not clear and it is distorted.
An opaque object will not allow light pass through it. It completely obstructs the ray of path of light. An opaque body will produce an image on the screen.

Answer:
The speed of the kid and the skateboard together is 0.723 m/s
Explanation:
Let the mass of the kid be
Let the mass of the skateboard be
The initial speed of the skateboard,
The initial horizontal speed of the boy as he jumps on the skateboard,
Let the speed of the kid and the skateboard together be v
According to the principle of conservation of momentum:
Substituting the appropriate values into the given equation
36 = 49.8 v
v = 36/49.8
v = 0.723 m/s
