Force is mass into acceleration
and pressure is force applied per unit area.
-- high enough pressure
-- high enough temperature
-- presence of fusible material
The length of the ship in terms of Emily's equal steps is 84.
The given parameters;
- <em>equal steps forward = 210</em>
- <em>equal steps backward = 42</em>
Defined parameters:
- <em>Let the constant velocity of the ship = V</em>
- <em>Let the velocity of Emily = Vs</em>
- <em>Let the </em><em>length </em><em>of the </em><em>ship </em><em>= </em><em>d</em>
- <em>Let the time of motion, = t</em>
The velocity of Emily when moving forward in the direction of the ship:
The velocity of Emily when moving in opposite direction to the ship:
The constant velocity of the ship:
Apply relative velocity formula to determine the length of the ship:
<em>For </em><em>forward </em><em>(same direction) motion:</em>
<em>For </em><em>backward </em><em>(opposite direction) motion</em>:
Thus, we can conclude that the length of the ship in terms of Emily's equal steps is 84.

Emily sees a ship traveling at a constant speed along a straight section of a river. She walks parallel to the riverbank at a uniform rate faster than the ship. She counts 210 equal steps walking from the back of the ship to the front. Walking in the opposite direction, she counts 42 steps of the same size from the front of the ship to the back. In terms of Emily's equal steps, what is the length of the ship

About 96 ounces of water a day.
Answer:
The apparent weight of the pilot is 3311 N
Explanation:
Given;
radius of the vertical circle, r = 600 m
speed of the plane, v = 150 m/s
mass of the pilot, m = 70 kg
Weight of the pilot due to his circular motion;
Real weight of the pilot;
Apparent weight - Real weight of pilot = weight due to centripetal force
Therefore, the apparent weight of the pilot is 3311 N
