Long periods of unusually low precipitation are called?

Answer:

the answers the correct one is d

Explanation:

The speed of sound is constant so we can use the relations of uniform motion

v = x / t

x = v t

now let's calculate the distance for each person

t = 5s

x₁ = 300 5

x₁ = 1500 m

t = 6s

x₂ = 300 6

x₂ = 1800 m

therefore we have two possibilities

a) the two people are on the same side, therefore the distance between them is

Δx = x₂- x₁

Δx = 1800 - 1500

Δx = 300 m

let's reduce to km

Δx = 0.300 km

b) people are on opposite sides of the sound

Δx = x₂ + x₁

Δx = 1800 + 1500

Δx = 3300 m

Δx = 3.3 km

when checking the answers the correct one is d

A client with hypertension who weighs 72.4 kg is receiving an infusion of nitroprusside (Nipride) 50 mg in D5W 250 ml at 75 ml/h

Mkey [24]

To solve this problem it is necessary to simply apply the concepts related to cross-multiply and proportion between units.

Let's start first by relating the amount of dose needed to be supplied per hour, in other words,

The infusion of 250ml should be supplied at a rate of 75ml / hour, so what amount x of mg hour should be supplied with 50Mg.

$\frac{x}{75ml/hour} \rightarrow \frac{50mg}{250ml}$

$x \rightarrow \frac{50mg*75ml/hour}{250ml}$

$x \rightarrow \frac{3750mg}{250hour}$

$x \rightarrow 15\frac{mg}{hour}$

Converting to mcg units we know that 1mg is equal to 1000mcg and that 1 hour contains 60 min, therefore

$x \rightarrow 15\frac{mg}{hour}$

$x \rightarrow 15\frac{mg}{hour}(\frac{1000mcg}{1mg})(\frac{1hour}{60min})$

$x \rightarrow 250mcg/min$

The dose should be distributed per kilogram of the patient so if the patient weighs 72.4kg,

$Dose = \frac{250mcg/min}{72.4kg}$

$Dose = 3.5 \frac{mcg/min}{kg}$

Therefore the client will receive 3.5mcg/kg/min.

Which example best demonstrates how unbalanced forces change the speed of an object's motion?

exis [7]

I don’t see a picture but unbalanced forces could be two boys pushing with a combined force of 400 Newton’s but the surface of what the box is laying on being 600 meaning since the ground is creating a higher force in the form of friction it will slow the boys down. When forces are unbalanced it means that the object can not be still or moving at a constant speed when one force is greater by a significant amount the object either slows quickly or accelerates fast depending on which factor is greater.

Let at any instant of time the speed is vo and the angle made by the bike with the horizontal is given

now we have
