Answer:
Depth of the pool, h = 4.004 cm
Explanation:
Pressure at the bottom, P = 39240 N/m²
The density of water, d = 1000 kg/m³
The pressure at the bottom is given by :
P = dgh
We need to find the depth of pool. Let h is the depth of the pool. So,


h = 4.004 m
So, the pool is 4.004 meters pool. Hence, this is the required solution.
Answer:
Description.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.
A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.
For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.
Hence, if the reference point changes, the description of position changes, but the actual position does not change.
1. There is tension acting in the rope. The rope being pulled from the brown dog exerts tension force in the direction of the black dog and according to Newtons 3rd law the black dog would exert an equal and opposite force of tension in the rope towards the brown dog so there would be no motion at this point;
<span>2. The brown dog and the black dog would be pushed away from each other at equal force but in opposite direction according to Newtons 3rd law. </span>
<span>This could also be related to Newtons 2nd law which is about resultant force and F=ma but since the question only asks for 3rd law its probably not appropriate.</span>
