Suppose we replace both hover pucks with pucks that are the same size as the originals but twice as massive. otherwise, we keep
kvv77 [185]

This pair of pucks will rotate at the same rate.

Further Explanation:

Hover Puck:  

The Hover Puck coasts effectively on a self-produced pad of air until followed up on by an outside power.  

Employments of hover puck:  

The Hover Puck coasts effectively on a self-produced pad of air until followed up on by an outside power.  

• Use one Hover Puck to show themes from Newton's First Law to impacts to reflection.  

• Use at least two pucks to examine the protection laws in two measurements.  

• Set up a bowling alley utilizing plastic beverage bottles.  

Innovation of hover puck:  

The First Rubber Hockey Pucks Were Made From Sliced-Up Lacrosse Balls. At the point when the game moved inside, entire balls were initially utilized, yet arena proprietors before long thought that it was desirable over cut them into thirds and keep the center segment. This fundamental plan was the standard by 1885.  

hockey puck was developed:  

The hockey puck appeared in 1875. It's hazy who really imagined it. Specialists accept the main hockey puck was likely only an elastic ball cut down the middle. This gave players an article with a level side that would slide over the ice.

Subject: physics

Level: High School

I am Lyosha [343]

Answer:

Option b. Dark spot

Explanation:

Michelson interferometer gives the path difference of the light as path difference, d as twice the distance moved or covered by the mirror M_{2}, x and is given as:

d= 2x

Since, its an even multiple, we obtain a bright fringe

now, when the move half the distance, i.e., \frac{x}{2}

Therefore, the path difference for half the distance \frac{x}{2} is:

d = x

As it is clear that its an odd multiple which correspond to dark spot as the final image

A sports car moving at constant speed travels 164 m in 13.77 s. If it then brakes and comes to a stop in 3.6 s. What is its acce
Sergio039 [100]

Answer:

a = - 0.3376 g's

Explanation:

The sports car has a constant speed when travelling. Covered 164 m in 13.77 s. Thus, speed = 164/13.77 m/s

It brakes and now comes to a stop in 3.6 s.

Thus final velocity = 0 m/s

Formula for acceleration is;

a = (v - u)/t

a = (0 - (164/13.77))/3.6

a = -3.308 m/s²

In terms of g's", where 1.00 g = 9.80 m/s², we have;

a = -3.308/9.8 g's

a = - 0.3376 g's
