Explanation :

Noble gases are the elements of group 18. This series contains helium, neon, radon krypton and radon.

The noble gases are the least reactive of any elements on the periodic table. This is because they have eight valance electrons in its outermost shell.

Non-metals or poly atomic ions forms  acidic compounds with hydrogen. For example : HCl, H_2SO_4 \ and\ H_3PO_4 etc forms acidic compounds with hydrogen.

The halogens are the most reactive among all the elements. This is because halogens suddenly combines with most of the metals. They are never seen uncombined in nature.

For example : Chlorine, fluorine and astatine are some halogens.

Consider a transformer used to recharge rechargeable flashlight batteries, that has 500 turns in its primary coil, 4 turns in it
Ilia_Sergeevich [38]

Answer:

Output Voltage = 0.96 volts

Explanation:

As we know by the equation of transformer we have

\frac{V_1}{V_2} = \frac{N_1}{N_2}

here we know that

V_1 = voltage of primary coil = 120 Volts

V_2 = voltage of secondary coil

N_1 = number of turns in primary coil = 500

N_2 = number of turns in secondary coil = 4

now we will have

\frac{120}{V} = \frac{500}{4}

V = 0.96 Volts

Suppose the block is released from rest with the spring compressed 5.00 cm. The mass of the block is 1.70 kg and the force const
IRISSAK [1]

First, let's calculate the total mechanical energy when the block is at rest and the spring is compressed 5 cm:

\begin{gathered} ME=PE+KE\\ \\ ME=\frac{kx^2}{2}+\frac{mv^2}{2}\\ \\ ME=\frac{955\cdot0.05^2}{2}+0\\ \\ ME=1.194\text{ J} \end{gathered}

Now, let's use this total energy to calculate the velocity when the spring is compressed by 2.5 cm:

\begin{gathered} ME=PE+KE\\ \\ 1.194=\frac{kx^2}{2}+\frac{mv^2}{2}\\ \\ 2.388=955\cdot0.025^2+1.7v^2\\ \\ 1.7v^2=2.388-0.597\\ \\ 1.7v^2=1.791\\ \\ v^2=\frac{1.791}{1.7}\\ \\ v^2=1.0535\\ \\ v=1.026\text{ m/s} \end{gathered}

Therefore the speed is 1.026 m/s.

) The radius of sphere measured repeated values 5.63 m, 5.54 m and 5.53 m. Determine the most
Nadusha1986 [10]

Answer:

v_{ average} = 5.57

Explanation:

The most probable value of a measure is

       v_average = \frac{1}{N} ∑ x_i

where N is the number of measurements

in tes case N = 3

         v_{average} = ⅓ (5.63 +5.54 + 5.53)

         V_{average} = 5,567

The number of significant figures must be equal to the number of figures that have the least in the readings.

          v_{ average} = 5.57
