A 30.0-kgkg box is being pulled across a carpeted floor by a horizontal force of 230 NN , against a friction force of 210 NN . W

Agata [3.3K]

Answer:

The acceleration of the box is 0.67 m/s²

Explanation:

Given that,

Mass of box = 30.0 kg

Horizontal force = 230 N

Friction force = 210 N

We need to calculate the acceleration of the box

Using balance equation

$F-f_{k}=ma$

$a=\dfrac{F-f_{k}}{m}$

Where, F = horizontal force

$f_{k}$ =frictional force

m= mass of box

a = acceleration

Put the value into the formula

$a=\dfrac{230-210}{30}$

$a=0.67\ m/s^2$

Hence, The acceleration of the box is 0.67 m/s²

A(n ______ is a well-blended mixture that appears to be a single substance

Natali [406]

None of the choices is a suitable fill-in for the blank.

The question is fishing for "solution", but that makes
the statement false and misleading.

Salad dressing is a well-blended mixture.
Blood is a well-blended mixture.
Milk is a well-blended mixture.
Petroleum is a well-blended mixture.
None of these substances is a solution.
A solution is not a well-blended mixture.

A certain aircraft can fly 612 miles with the wind in 3 hours and travel the same distance against the wind in 6 hours. What is

Andreas93 [3]

Answer:

51 mph

Explanation:

Given: A certain aircraft can fly 612 miles with the wind in 3 hours and travel the same distance against the wind in 6 hours.

Formula: $Speed=\dfrac{Distance}{Time}$

Let speed of aircraft be x mph and speed of wind y mph

Aircraft along wind:

Actual speed of aircraft = x + y

Time taken = 3 hours

Distance = 612 miles

$\therefore x+y=\dfrac{612}{3}$

$x+y=204----------(1)$

Aircraft against wind:

Actual speed of aircraft = x - y

Time taken = 6 hours

Distance = 612 miles

$\therefore x-y=\dfrac{612}{6}$

$x-y=102----------(2)$

By solving equation (1) and equation (2) and we get

x = 153 mph

y = 51 mph

Hence, The speed of wind will be 51 mph

146,000,000 Express this amount in gigadollars

Tema [17]

I saw an example of yahoo saying that 114,000,000= 0.114, so ima take a guess and say that the way in expressing 146,000,000 in gigadollars would be 0.146. I'm sorry if I am wrong. But if it is right give me a thanks so I could know if I was right or not.
