For the hypothetical salaries in the following

Physics
1 answer:
FrozenT [24]3 years ago
3 0

Answer: $43400 per year

Explanation:

The Data set of hypothetical salaries is given as:

$46,000 per year,

$20,000 per year,

$33,000 per year,

$27,000 per year,

$91,000 per year.

The average salary per year will be the addition of the salaries per year above which will then be divided by 5. This will be:

= ($46,000 + $20,000 + $33,000 + $27,000 + $91,000) / 5

= $217000/5

= $43400 per year

The average salary per year will be $43400

Water, which we can treat as ideal and incompressible, flows at 12 m/s in a horizontal pipe with a pressure of 3.0 x 10^4 Pa. If
frez [133]

Answer:

p2 = 9.8×10^4 Pa

Explanation:

Total pressure is constant and PT = P = 1/2×ρ×v^2  

So p1 + 1/2×ρ×(v1)^2 = p2 + 1/2×ρ×(v2)^2

from continuity we have ρ×A1×v1 = ρ×A2×v2  

v2 = v1×A1/A2  

and  

r2 = 2×r1

then:

A2 = 4×A1  

so,

v2 = (v1)/4  

then:

p2 = p1 + 1/2×ρ×(v1)^2 - 1/2×ρ×(v2)^2 = p1 + 1/2×ρ×(v1)^2 - 1/2×ρ×(v1/4)^2  

p2 = 3.0×10^4 Pa + 1/2×(1000 kg/m^3)×(12m/s)^2 - 1/2×(1000kg/m^3)×(12^2/16)  

     = 9.75×10^4 Pa

    = 9.8×10^4 Pa

Therefore, the pressure in the wider section is 9.8×10^4 Pa

How does 1 horsepower compare to 1 watt power​
yaroslaw [1]

"Life is wasted if we do not grasp the glory of the cross, cherish it for the treasure that it is, and cleave to it as the highest price of every pleasure and the deepest comfort in every pain. What was once foolishness to us—a crucified God—must become our wisdom and our power and our only boast in this world.” - John Piper

A 70kg skier moving at 5 m/sec down a slope what is the skier’s momentum
olga2289 [7]

<u><em>Answer:</em></u>

Momentum of the skier is 350 Kg.m/sec

<u><em>Explanation:</em></u>

<u>Momentum of a body can be calculated using the following rule:</u>

P = m * v

<u>where:</u>

P is the momentum of the body

m is the mass of the body given as 70 Kg

v is the velocity of the body given as 5 m/sec

<u>Substitute with the givens in the above rule to get the momentum of the skier as follows:</u>

P = m * v

P = 70 * 5

P = 350 Kg.m/sec

Hope this helps :)
