Mnenie [13.5K]

The information that should be added to the chart in order to find out who ran a greater distance is THE UNITS USED TO MEASURE DISTANCE EACH DAY.

In science, the use of units if very important and each record made must be accompany with relevant units that are appropriate for the measurement taken. If units are not used along with data, it will be very difficult to quantify the values that are recorded. Scientists all over the world use SI units in their works in order to ensure uniformity.

A student has a balloon that looks shiny like a metal and wants to perform an experiment to determine if it contains any metal.
zheka24 [161]

Answer:

Charge the balloon, hold it near an electroscope, and determine if the electroscope leaves move.

Explanation:

The gold leaf electroscope is an instrument used to detect if a body is charged. It has two gold leafs suspended from a brass stem in a vacuumed glass jar and connected to a metal cap(Toppr).

When the test body is allowed to touch the metal cap, a change in the size of the leaves shows whether the body is charged or not.

Since we are suspecting the balloon to be made up of a metal; metals can be charged. We can test if there is really a charge on the balloon by bringing it near an electroscope to see if the electroscope moves.

A metal foil has a threshold frequency of 5.45 \times 10^{14} \text{ } \text{Hz}5.45×10 14 Hz. Which of the colors of visible l
nalin [4]

Answer:

Green, Blue, Indigo, Violet

Explanation:

According to Einstein's equation of photoelectric effect, the kinetic energy of emitted photoelectron is the difference between the energy of the incident photon and the work function of the metal. The work function of the metal referee to the minimum energy that must be supplied in order to eject an electron from a metal surface. The energy of the incident photon must exceed the work function of the metal.

When we look at the electromagnetic spectrum, only the selected colours have frequency above the threshold frequency as shown by the image attached below.

The element which has the electronic configuration is CHLORINE.
The atomic number of chlorine is 17 and it has 7 valence electrons in its outermost shell. Because it needs only one more electrons to have a stable octet, it usually react with metals from group one of the periodic table who are normally willing to donate the single electrons in their outermost shells. The ground state electronic configuration of chlorine atom is 1S^2 2S^2 2P^6 3S^2 3P^5.
