my hypothesis is that If you drop a piece of buttered toast, it will land butter side down.


I tested it by dropping 10 pieces of buttered toast off the table and noted on which side it landed


It could be falsified cause I just made all of this up. In essence, it's like flipping a coin, 50/50 chance so I could say that 5 landed butter up and 5 landed butter down.

Car A is traveling at 20.0 m/s and car B at 27.0 m/s.
Savatey [412]

Take the moment car A starts to accelerate to be the origin. Then car A has position at time <em>t</em>

<em>x</em> = (20.0 m/s) <em>t</em> + 1/2 (2.10 m/s²) <em>t</em>²

and car B's position is given by

<em>x</em> = 300 m + (27.0 m/s) <em>t</em>

<em />

Car A overtakes car B at the moment their positions are equal:

(20.0 m/s) <em>t</em> + 1/2 (2.10 m/s²) <em>t</em>² = 300 m + (27.0 m/s) <em>t</em>

300 m + (7.00 m/s) <em>t</em> - (1.05 m/s²) <em>t</em>² = 0

==>  <em>t</em> ≈ 20.6 s

A submarine dives 185.0 m at an angle of 15.0◦ below the horizontal. What is the horizontal component of the submarine’s displac
stepan [7]

Answer:

Horizontal component, d_x=178.69\ m

Explanation:

It is given that,

Displacement of the submarine, d = 185 m

It is at an angle of 15 degrees below the horizontal. We need to find the horizontal component of the submarine's displacement. It is given by :

d_x=d\ cos\theta

Substituting the values in above equation as :

d_x=185\times \ cos(15)

d_x=178.69\ m

So, the horizontal component of the submarine’s displacement is 178.69 meters. Hence, this is the required solution.
