Ok . So i know its already explained but can any1 explain a bit more[Both of them]. Write Heading 'Activity 9.1' [then explain]then heading 'Activity 9.2 [then explain] So that i know which explanation is for which activity. Plsssss Help!

Answer»

Activity 9.1Explanation: A moving body wants to REMAIN in the state of motion while a RESTING body tends to remain in a steady position only. This physicist call “law of inertia” or Newton’s first law of motion. When an external force enough to break the inertia comes and applies to the body then only the body changes its state of motion. Here the striker hits the bottom COIN and breaks the inertia of the bottom coin. The bottom coin applies a frictional for on the rest of the pile of the coins. But this force is not enough to break the inertia of the other coins. As a RESULT, the remaining coins fall back to the bottom of the CARROM board.Activity 9.2Explanation: This activity is similar to activity 9.1 also. There we struck the pile of coins using the striker.   Here the coin is at the rest also wants to remain at the rest: Newton’s first law of motion. When we hit the card fast, the energy of the card does not transfer to the coin. As a result, the coin does not move and falls inside the glass due to gravity.

write a short note on some devices that are used to measure the volume of liquids. (conical measuring cans and cylindrical measuring cans)​

Answer»

Explanation:A conical measure is a type of laboratory glassware which CONSISTS of a conical cup with a notch on the TOP to ALLOW for the easy pouring of liquids, and graduated markings on the side to allow easy and accurate measurement of volumes of liquid. They may be made of plastic, glass, or borosilicate glass.A graduated cylinder, also known as measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical SHAPE. Each marked LINE on the graduated cylinder represents the amount of liquid that has been measured.Please mark as brainliest

[tex] \mathfrak{koi\:help\: \ \textless \ br /\ \textgreater \ karo!}[/tex]Explain the process of Neutron Star formation?Don't spam​

Answer»

stars are created when giant stars DIE in supernovas and their cores collapse, with the protons and electrons essentially melting into each other to form neutrons. Neutron stars are city-size stellar objects with a mass about 1.4 times that of the sun.When stars FOUR to eight times as massive as the sun explode in a VIOLENT supernova, their outer layers can blow off in an often-spectacular display, leaving behind a SMALL, DENSE core that continues to collapse. Gravity presses the material in on itself so tightly that protons and electrons combine to make neutrons, yielding the name "neutron star."mark me as brainliest I hope it helps you 10 thanks = inbox
