madreJ [45]

Explanation:

m = 19 oz × (28.3 g/1 oz) = 537.7 g

V = 92.8 mL

\rho = \dfrac{m}{V}= \dfrac{537.7\:g}{92.8\:mL} = 5.79\:\frac{g}{mL}

What is the difference between mechanical advantage and distance advantage? ​
eimsori [14]
A machine's distance mechanical advantage shows the effectiveness of the machine in moving an object a greater distance than the input distance. The equation for the distance mechanical advantage is the output distance divided by the input distance. Note: Most science books only consider force mechanical advantage. I HOPE THIS HELPS!

6. A spring whose spring constant is 850 N/m is compressed 0.40 m. What is the maximum
vladimir2022 [97]

Given :

A spring whose spring constant is 850 N/m is compressed 0.40 m.

To Find :

The maximum speed it can give to 0.50 kg ball.

Solution :

We know, Kinetic energy = Energy stored in spring

\dfrac{mv^2}{2}= \dfrac{kx^2}{2}\\\\v= x\sqrt{\dfrac{k}{m}}\\\\v = 0.40\times \sqrt{\dfrac{850}{0.50}}\\\\v = 16.49\ m/s

Hence, this is the required solution.

An executive drove from home at an average speed of 30 mph to an airport where a helicopter was waiting. The executive boarded t
Lorico [155]

Answer:

The distance from the airport to the corporate offices is 110 miles.

Explanation:

Let d be the distance from the airport to the office (at a velocity of 75 mph), the person travels an entire distance of 156 miles, 156-d is the distance from home to the airport (at a velocity of 30 mph).

The equaiton for velocity is:

Velocity=\frac{distance}{time}

From this you can find the equation for the time:

time=\frac{distance}{velocity}

You can use the total time to find the distance d because you know that the time between the home and the airport plus the time between the airport and the work is 3 hours:

3=\frac{156-d}{30}+\frac{d}{75}

You can solve the equation to find d:  

3=\frac{156*75-75d+30d}{30*75}

3=\frac{11700-45d}{2250}\\d=-\frac{(3*2250)-11700}{45}\\d=110

Now you have that the distance between the airport and the office is 110 miles.
