The drawing shows a hydraulic chamber with a spring (spring constant = 1600 N/m) attached to the input piston and a rock of mass

Triss [41]

Answer:

$\Delta x=245\ mm$

Explanation:

Given:

spring constant of the spring attached to the input piston, $k=1600\ N.m^{-1}$

mass subjected to the output plunger, $m=40\ kg$

<u>Now, the force due to the mass:</u>

$F=m.g$

$F=40\times 9.8$

$F=392\ N$

<u>Compression in Spring:</u>

$\Delta x=\frac{F}{k}$

$\Delta x=\frac{392}{1600}$

$\Delta x=0.245\ m$

$\Delta x=245\ mm$

You and your roommate are moving to a city360 mi away. Your roommate drives a rental truck at a constant 50 mi/h , and you drive

AnnyKZ [126]

Answer:

42 minutes

Explanation:

First, let us find out the time required by the roommate, who is driving the truck, to reach the city.

We know that,

$time=\frac{distance}{speed} =\frac{360}{50} hrs=7.2hrs$

Now, you are planning to rest a bit after traveling for an hour. So,

distance covered in that 1 hour = $60mi/h\times1h=60 miles$

time required by you to cover the total distance = $\frac{360mi}{60mi/h} =6hours$

If you wish reach at the destination half an hour (0.5 h) before your roommate, you can expend a total of $7.2-0.5=6.7hours$ throughout your journey.

Hence, you can rest for $6.7-6=0.7hours=(0.7\times60)minutes=42minutes$

To heat the house, the boiler transfers 15 MJ of energy in 10 minutes.

Harrizon [31]

The formula is P = E/t, where P means power in watts, E means energy j , and t means time in seconds. This formula states that power is the consumption of energy per unit of time.

P = 15 M / 10*60

M = mega = 10⁶

15 *10⁶ / 600

= 25000 watt
