Difference between freefall and weightlessness.​
Margaret [11]

Answer:

Differences between freefall and weightlessness are as follows:

<h3><u>Freefall</u></h3>
  • When a body falls only under the influence of gravity, it is called free fall.
  • Freefall is not possible in absence of gravity.
  • A body falling in a vacuum is an example of free fall.

<h3><u>Weightlessness</u></h3>
  • Weightlessness is a condition at which the apparent weight of body becomes zero.
  • Weightlessness is possible in absence of gravity.
  • A man in a free falling lift is an example of weightlessness.

Hope this helps....

Good luck on your assignment....

The Kentucky Derby is one of the most exciting horse races run every year. In 1973, the horse Secretariat set a record that stil
lawyer [7]

Answer:

69.44kJ

Explanation:

Kinetic energy is expressed as;

KE = 1/2mv^2

m is the mass = 500kg

v is the velocity

Get the velocity;

v = displacement/time

velocity = 2000/120

velcoity = 16.7m/s

Gt the kinetic energy

KE = 1/2 * 500 * 16.7²

KE = 250*277.78

KE = 69,444.4Joules

Since 1000J = 1kJ

69,444.4Joules = 69,444.4/1000

69,444.4Joules = 69.44kJ

Hence the Secretariat's average kinetic energy is  69.44kJ

The speed at which the package hits the ground is really fast! If a package hits the ground at such a speed, it can be crushed a
Fed [463]

Answer:

B. Decrease the plane’s speed and height

Explanation:

Decrease in speed of plane:

When the speed of the plane is decreased then initial velocity of the package will be lesser. As a result, final velocity will also be lesser because in this case final velocity depends upon the initial velocity.

Decrease in height:

According to law of conservation of energy:

Loss in potential energy = Gain in Kinetic energy  

                                 mgh = ½ mV^2

It means with the decrease in height less potential energy will be converted to kinetic energy. As package has constant mass so it will gain less velocity.

How would you set up SMART goals for your clients?​
aleksklad [387]

Answer: The client must be advised while preparing a goal either for a treatment or for a fitness class.

Explanation:

The client goal must be set in a way that it should be measurable, attainable, time-bound.

The measurable goal is the in the sense that the client can measure own success.

The attainable is in the sense  the client can achieve and perform all set plans in the goal.

Time-bound is in the sense that the client can devote sufficient time to obtain success.
