Answer:

x= 80 cm : Spring stretch

Explanation:

Hooke's law:

The force applied to a spring is proportional to the spring stretching:

F=K*x (Formula (1)

Where:

F=Force applied to the spring (N)

K= spring elasticity constant (N/m)

x= spring stretch (m)

Known data

F=520 N

k=650 N/m

Problem development

We apply formula (1) for calculate the spring strech (x):

F=K*x

520N=(650 N/m) *x

x= (520N) / (650 N/m)

x= 0.8 m = 0.8m* 100cm/m = 80cm

x= 80 cm

Sry,I only know the answer of q2

Chlorine is a non metal because it is bad conductor of heat and sodium is a metal because it is good conductor of heat.

The 3 ways in which metal is different from non metal are given below:

1)metal are good conductor of heat but nonmetal are bad conductor of heat.

2)metals are malleable but non metal aren't malleable.

3)metals are generally ductile but non metal aren't ductile.

Hope it will helpyou!

4-12. The morning inspection of the tank farm finds a leak in the turpentine tank. The leak is repaired. An investigation finds

bonufazy [111]

Answer:

a) $V=759.8727\ ft^3$

b) $\dot V=1.403\times 10^{-3}\ ft^3.s^{-1}$

c) $t\approx29.541\ s$

Explanation:

Given:

diameter of hole in the tank, $d'=0.1\ in=\frac{1}{120}\ ft$

position of the hole form the tank bottom, $h' =7\ ft$

initial level of turpentine in the tank before the leakage, $h_i=17.3\ ft$

level of turpentine in the tank after the repair of leakage, $h_f=13\ ft$

diameter of the tank, $d=15\ ft$

density of turpentine oil, $\rho=55\ lbm.ft^3$

Now, volume of turpentine spilled:

$V=A.(h_i-h_f)$

where:

$A=$ area of the cross section of the tank's volume

$V=\pi .\frac{d^2}{4} \times(h_i-h_f)$

$V=\pi\times\frac{15^2}{4} \times(17.3-13)$

$V=759.8727\ ft^3$

When the tank was full the liquid level was highest:

so velocity form the height of the hole will be given as:

$v=\sqrt{2g.(h_i-h')}$

$v=\sqrt{2\times 32.12\times (17.3-7) }$

$v=25.722\ ft.s^{-1}$

<u>Now we have the flow rate of the spillage given by:</u>

$\dot V=(\pi.\frac{d'^2}{4}) \times v$

$\dot V=\pi\times \frac{(\frac{1}{120})^2 }{4} \times 25.722$

$\dot V=1.403\times 10^{-3}\ ft^3.s^{-1}$

Total time the leak was active can be calculated as:

$t=\frac{V}{\dot V}$

$t=\frac{759.8727}{25.722}$

$t\approx29.541\ s$

6. What is the mass of a boy who is standing on top of a 1.5 meter high

puteri [66]

Answer:

m = 50 [kg]

Explanation:

The potential energy can be calculated by means of the following equation.

$E_{p}=m*g*h$

where:

Ep = potential energy = 735 [J]

m = mass [kg]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 1.5 [m]

Now replacing:

$735=m*9.81*1.5\\m = 50 [kg]$

Why is chlorine bonded by a single covalent bond, but Oxygen bonded by a double covalent bond?

inna [77]

Answer:

chlorine is a non-metal.

Explanation:

a chlorine atom has 7 electrons in its outer shell. chlorine is in group 7 of the periodic table. two chlorine atoms will each share one electron to get a full outer shell and form a stable cl2 molecule.
