The answer is:

noble gases will not form compounds.

The explanation:

-The noble gas family, all of the elements in Group Zero.

-The list of noble gases include helium(He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

- these elements don't like to react, we don't use them because of they have 8 valence electrons already and don't like to lose or gain electrons so, they will not form compounds.

A vertical scale on a spring balance reads from 0 to 155 N . The scale has a length of 10.0 cm from the 0 to 155 N reading. A fi

Answer:

mass of the fish is 8.11 kg

Explanation:

As we know that the frequency of oscillation of spring block system is given as

$f = \frac{1}{2\pi}\sqrt{\frac{k}{m}}$

here we know that the reading of scale varies from 0 to 155 N from length varies from x = 0 to x = 10 cm

Now we have

$k = \frac{155}{0.10} N/m$

$k = 1550 N/m$

so now we have

$2.20 = \frac{1}{2\pi}\sqrt{\frac{1550}{m}}$

$m = 8.11 kg$

so mass of the fish is 8.11 kg

Old-fashioned pendulum clocks are powered by masses that need to be wound back to the top of the clock about once a week to coun

Answer:

Energy, E = 178.36 J

Explanation:

It is given that,

Mass 1, $m_1=4\ kg$

Mass 2, $m_2=4\ kg$

Mass 3, $m_3=6\ kg$

Height from which they are dropped, h = 1.3 m

Let m is the energy used by the clock in a week. The energy is equal to the gravitational potential energy. It is given by :

$E=(m_1+m_2+m_3)gh$

$E=(4+4+6)\times 9.8\times 1.3$

E = 178.36 J

So, the energy used by the clock in a week is 178.36 Joules. Hence, this is the required solution.
