Answer:
Hey hi,
Explanation:
<em>Parachutes are designed to reduce terminal Velocity, so when a person is near to ground will have less speed and the avg speed of person hitting the ground </em><em>with</em><em> parachutes will have 17 mph so which makes the person to easily walk off or fell sleep. </em>

The equation for the energy (E) of the electron may be obtained by the equation,
E = hc / λ
where h is Planck's constant, c and λ are speed of light and wavelength, respectively. Substituting the values,
(-2.179x10^-18 - -8.720x10^-20) = (6.626x10^-34)(2.998x10^8)/ λ
From the equation, the value of λ is approximately equal to 9.496x10^-8 m.
The sonar pulse takes t=4.2 s to reach the ocean bottom and then to travel back tothe ship. If we call d the depth of the ocean bottom, this means that the sonar pulse covered a distance equal to 2d in a time of 4.2 s.
The speed of the sonar pulse is the speed of sound in water at 25C, so looking at the table is v=1493 m/s. Using the relationship
between space and time for a uniform motion, and keeping in mind that the total distance covered by the pulse is 2d, we can write:
which becomes
so, the ocean bottom is 3135 m deep.
F = 245N
The Acceleration of an object in a free fall is 9.8 m/s
force= 25kg X 9.8m/s
