What is the acceleration if we speed up from 10m/s to 30 m/s in 10 seconds
lina2011 [118]
Acceleration= change in speed/ change in time

30-10= 20 (change in speed)
Time= 10 seconds

20/10= 2
Acceleration= 2 m/s^2

Hope this helps! :)

A 50 kg person steps off a diving platform that is 10 meters above the water below (Olympic height). With what speed do they hit
Nookie1986 [14]

Answer:

14 m/s

Explanation:

The following data were obtained from the question:

Mass = 50 kg

Initial velocity (u) = 0 m/s

Height (h) = 10 m

Acceleration due to gravity (g) = 9.8 m/s²

Final velocity (v) =?

The velocity (v) with which the person hit the water can be obtained as shown below:

v² = u² + 2gh

v² = 0² + (2 × 9.8 × 10)

v² = 0 + 196

v² = 196

Take the square root of both side

v = √196

v = 14 m/s

Therefore, he will hit the water with a speed of 14 m/s

Convection is the rising of
Ad libitum [116K]

Since the outer plumage of the penguin can resist the flow of heat in the cold antarctic air they might gain a little of this heat to keep them warm by thermal convection.

<u>Explanation:</u>

  • Convection is the circular movement that happens when hot air/liquid moves with molecules that were fast, making it less dense rises while the cold air/liquid drops down.
  • Also, they follow the technique of standing together always in a group which further helps them to decrease the loss of heat between them.
  • The plumage of penguin provides 80 percent of total insulation and is highly resistant to wind penetration.
