Explanation:

Metals are the substances which tend to lose their valence electrons in order to attain stability.

For example, metals of group 1 are lithium, sodium, potassium, rubidium and cesium.

And, each of these elements have only 1 valence electron present. So, it is much easier to lose just one electron rather than losing 2 or 3 valence electrons.

Hence, alkali metals are the most reactive substances of the periodic table and they are present at extreme left side of periodic table.

Therefore, we can conclude that the most reactive metals are located at the extreme left of the periodic table.

Why does an object have a different weight on the moon than it does on Earth? Everything is weightless in space. Objects move mo

ankoles [38]

-- "Weight" is the gravitational attraction between TWO objects.

-- Its 'strength' depends on the mass of BOTH masses.
If either mass changes, then the gravitational force between them changes.

-- Your 'weight' on Earth depends on your mass and the Earth's mass.

-- Your 'weight on the moon depends on your mass and the Moon's mass.

From the list of choices, the best one is "The Earth and moon have
different values for the acceleration due to gravity.", although that
doesn't really explain much.

One way to measure g on another planet or moon by remote sensing is to measure how long it takes an object to fall a given dista

devlian [24]

Answer:

2.24 m/s²

Explanation:

Using equation of motion

s = ut + $\frac{1}{2}$ at²

u = 0 , t = 3.17 s , s = 11.26 m

Put these values in the equation above

11.26 = 0 +.5 x a( 3.17)²

a = 2.24 ms⁻².

So acceleration due to gravity on that planet will be 2.24 m s⁻².

The efficiency of the scissor is 200%.

<u>Explanation:</u>

Efficiency is defined as the ratio of output of any instrument or device or machine to the input supplied to it. So the greater the output the greater will be the efficiency of the device.

As here the work done by us on the system is said to be 10 J so this will be equal to the input work done on the system. And the work done by the system i.e., the scissor is 20 J, so this will be the output work.

So, the efficiency is the ratio of output to input as shown below.

Efficiency = $(\frac {20} {10} ) \times 100$ = 200

So, the efficiency of the scissor is 200%.
