6. Why are the atomic masses of elements usually decimal numbers?

The atomic mass of elements are usually decimals as it makes the atomic masses more accurate and exact. The mass of an atom is also the weighted average of the elements known isotopes and since it’s the average, the number is most likely going to be a decimal number.

I hope this helps :)

Carlos is looking at a picture of a convergent boundary on which a volcanic arc and a trench are identified. Which type of conve
Elan Coil [88]

The answer would be:

Oceanic-Oceanic Convergent Plate

This is why:

When two oceanic plates collide, the heavier of the two would subduct or in other words, go under the other plate. When this happens, ocean trenches and volcanic arcs form. The trench forms at the point oceanic plate goes under the other plate. And above the other plate that goes over create volcanic arcs.

Bună ziua, mă poate ajuta și pe mine cineva, spunândumi din ce substanțe este formată cărămida și care este formula
Ne4ueva [31]

Answer: De câte cărămizi am nevoie? Pentru un perete de cărămidă cu strat singular, înmulțiți lungimea peretelui cu înălțimea pentru a obține zona. Înmulțiți acea zonă cu 60 pentru a obține numărul de cărămizi de care ar trebui să aveți nevoie, apoi adăugați 10% pentru risipă. Acesta este răspunsul scurt și presupune dimensiuni „standard” de cărămidă și mortar.

alukav5142 [94]

Answer:

  7.86 g/cm³

Explanation:

  11.0 kg = 11,000 g

The density in g/cm³ is ...

As a child (with a mass of 35.0 kg) you take your 5.0-kg sled to Orchard Downs. If you are sliding down the hill on your sled, w
alukav5142 [94]

Velocity = 3.61 m/s

<h3>Further explanation</h3>

Given

mass of child = 35 kg

mass of sled = 5 kg

Kinetic energy = 260 J

Required

velocity

Solution

Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:

KE = 1/2.mv²

mass of object :

= mass child + mass sled

= 35 kg + 5 kg

= 40 kg

Input the value :

v²=KE : 1/2.m

v²= 260 : 1/2.40 kg

v²=13

v=3.61 m/s
