que tiempo tarda juan en su carro al llegar al trabajo si lleva una velocidad de 25 m/s a una distancia de 5m

kramer

Answer:

0.2s

Explanation:

Given parameters:

Speed = 25m/s

Distance = 5m

Unknown:

Time taken for Juan to get to his work = ?

Solution:

To solve this problem we use the relationship below:

Speed = $\frac{distance}{time}$

Time = $\frac{distance }{speed}$

So;

Time = $\frac{5}{25}$ = 0.2s

A quantity of a gas has an absolute pressure of 400 kPa and an absolute temperature of 110 degrees kelvin. When the temperature

KiRa [710]

Answer:

A) 854.46 kPa

Explanation:

P₁ = initial pressure of the gas = 400 kPa

P₂ = final pressure of the gas = ?

T₁ = initial temperature of the gas = 110 K

T₂ = final temperature of the gas = 235 K

Using the equation

$\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}$

Inserting the values

$\frac{400}{110}=\frac{P_{2}}{235}$

P₂ = 854.46 kPa

If a flea can jump straight up to a height of 0.550 m , what is its initial speed as it leaves the ground?

olga55 [171]

Let u = upward initial speed of the flea.

At the maximum height of h = 0.550 m, the vertical velocity is v = 0.
Therefore, from the formula
v² = u² - 2gh,
obtain
0 = u² - 2*(9.8 m/s²)*(0.55 m)
u² = 10.78 m²/s²
u = 3.283 m/s

Answer: The initial upward speed is 3.28 m/s (nearest thousandth)
