Answer:
S=2.693m
Explanation:
Let point
be the origin of the room and the fly is crawling at point
as shown in the attached photo:
#Distance of the fly from the corner of the room is defined as:

#Substitute the coordinate values in the above equation:

Hence, the distance of the fly from the corner of the room is 2.693m
D. I know that like the back of my hand
Answer:
(a) 
(b) 
(c) 
Explanation:
(a) According to Newton's second law, the acceleration of a body is directly proportional to the force exerted on it and inversely proportional to it's mass.

(b) According to Newton's third law, the force that the sled exerts on the girl is equal in magnitude but opposite in the direction of the force that the girl exerts on the sled:

(c) Using the kinematics equation:

For the girl, we have
and
. So:

For the sled, we have
. So:

When they meet, the final positions are the same. So, equaling (1) and (2) and solving for t:

Now, we solve (1) for 

Answer:
A freely suspended magnet comes to rest along the N-S direction.
Explanation:
-Irrespective of direction of suspension, the bar eventually comes to rest at earth's N-S direction.
-Bar end that points to Earth's north is called the <em>North Pole</em>. Bar end that point's to earth's south is called the <em>South pole</em>.
-The reason for this default positioning is called the Directive Property. This is because earth acts as an external magnetic field.
