Which term denotes that the mere presence of other people in your environment affects your behavior
Thepotemich [5.8K]

The term is Social facilitation.

Social facilitation can be defined as an improvement in performance caused by the mere presence of others, it can be further distinguished into two types:

  • co-action effects which is a phenomenon where increased task performance is caused by the mere presence of others doing the same task.
  • audience effect where performance is increased in the presence of a passive spectator/audience

Dr. John Paul Stapp was U.S. Air Force officer who studied the effects of extreme deceleration on the human body. On December 10
Nuetrik [128]

Answer:

acceleraions 5.76g and 20.55g

Explanation:

This constant acceleration exercise can be solved using the kinematic equations in one dimension

    Vf = Vo + a t

As part of the rest Vo = 0

    a = Vf / t

    a = 282/5

    a = 56.4 m / s2

In relation to the acceleration of gravity

    a ’= a / g = 56.4 / 9.8

    a ’= 5.76g

To calculate the acceleration to stop we use the same formula

     a2 = 282 / 1.40

     a2 = 201.4 m / s2

 This acceleration of gravity acceleration function is

     a2 ’= 201.4 / 9.8

     a2 ’= 20.55g

A car accelerates at a rate of 3 m/s^2. If its original speed is 8 m/s, how many seconds will it take the car to reach a final s
kkurt [141]

Answer:

\Large \boxed{\mathrm{5.67 \ seconds }}

Explanation:

\displaystyle \mathrm{acceleration \ = \ \frac{final \ velocity - initial \ velocity }{elapsed \ time}}

\displaystyle A \ = \ \frac{V_f - V_i }{t}

\displaystyle 3 \ = \ \frac{25 - 8 }{t}

\displaystyle 3 \ = \ \frac{17 }{t}

\displaystyle t \ = \ \frac{17 }{3} \approx 5.67
