Best Online Stock Trading Brokers for 2018 If you’re looking for a way to build more wealth in 2018, getting started with one of the best online brokerage accounts is a solid first step. Doing so will allow you to invest outside your traditional retirement accounts and on your own terms. The best part is, the best online brokerage firms charge little or no fees and offer excellent resources that can help you learn more about investing along the way. Of course, not all brokerage firms are created equal, and that’s why we took the time to break down each of their details and rank the top options on an array of factors. If you’re looking for a new way to invest this year and are ready to strike out on your own, the following online brokerage accounts should be at the top of your list.What Matters When You Trade Stocks on Your Own? Managing your own money can be a stressful endeavor. To minimize this, and to minimize information overload that tends to come from watching the markets 24/7, there are a few must-haves to look for in an online broker. Clean interface. When I trade, I want to be able to easily find my order entry ticket. I don’t want it buried under a number of drop downs. This interface should have intuitive access to see your balance, available cash, positions with real time P/L and all be easily navigated. Quick access to basic charting. A chart tells me where the stock has been recently. I don’t trade minute to minute anymore, so I don’t need complex tools like stochastics or retracement lines. All that’s important is that I have a basic chart on a yearly, monthly, weekly, daily and intra day time period. I use a chart to see current price relative to those time periods, mainly to avoid purchasing at a bad price. Low fees. One of the biggest roadblocks to building wealth is fees incurred to invest your hard-earned dollars. Because the fees charged by different brokerage firms vary so dramatically, it’s crucial to seek out options that charge low fees (or no fees) for account management and trades. There are over 50 online brokerages where you can open an account. Beyond the my three rules above, best online brokerage accounts aren’t just for trading stocks. Sure, many of them started as online stock trading accounts, but now they’re full-fledged trading, saving, investing, retirement planning, and banking machines. This industry is more complex than the average person thinks. You shouldn’t just pick any online broker and sign up for an account. The best online broker for one person is often completely different for the next person. Use this resource as a guide to your decision process. Figure out what features are best for you, and make your selection. What Makes a Great Online Broker? I analyzed a number of elements to come to my decision on which brokers are the best. Later in this post, I provide full details on how I selected the best online brokerages. When you take all the features, resources, trading platforms, and technology into account (while also considering every type of trader), the full-service brokers, like E*TRADE and TD Ameritrade are the best for the largest number of people. For those simply looking to make cheap trades, I would recommend going with Optionshouse. If you’re a very advanced trader, high-volume trader, or a professional who manages money, I recommend going with Interactive Brokers. However, I didn’t include Interactive Brokers on my list because they’re best for a very small group of traders and the platform is very complex. Top Qualities of Standout Online Trading Platforms Quality trading tools and technology Multiple trading platforms for all levels of traders Excellent mobile trading features Solid navigation that displays the relevant information where you want it Quality educational resources and research for trader development There’s more to selecting an online broker than price. You have to consider the resources you’re getting for the cost you pay per trade. For example, my colleague, who is also an ex-trader, likes to use a combination of stock and options trade in his longer-term trading. He recently switched over to Fidelity because he really liked the cash management features, but was very disappointed by complex order entry, sub-par options execution and frustrating navigation. He’s currently making the switch to one of the brokers I profile here.

Pengertian Kalor Jenis Dan Pola Soal Serta Pembahasannya

Definisi kalor merupakan salah satu bentuk energi yang sanggup berpindah dari benda satu ke benda lainnya. Kalor sanggup diberikan kepada benda atau diambil dari benda tersebut. Kalor sanggup diberikan pada suatu benda dengan cara pemanasan dan sebagai salah satu dampak ialah kenaikan suhunya. Kalor sanggup diambil dari suatu benda dengan cara pendinginan dan sebagai salah satu dampak ialah penurunan suhu.

Jadi, salah satu dampak dari sumbangan atau pengurangan kalor ialah perubahan suhu yang diberi lambang Δt. Dari sebuah hasil percobaan menawarkan bahwa dari pemanasan air dan minyak kelapa dengan massa air dan minyak kelapa yang sama, dengan selang waktu pemanasan yang sama ternyata banyaknya kalor yang diserap oleh air dan minyak kelapa tidak sama.

Untuk membedakan zat-zat dalam hubungannya dengan imbas kalor pada zat-zat itu dipakai konsep kalor jenis yang diberi lambang “c”. Kalor jenis suatu zat ialah banyaknya kalor yang diharapkan atau dilepaskan setiap kilogram massa untuk menaikkan atau menurunkan suhunya satu Kelvin atau satu derajad Celsius. Jika suatu zat yang massanya m memerlukan atau melepaskan kalor sebesar Q untuk mengubah suhunya sebesar ΔT, maka kalor jenis zat itu sanggup dinyatakan dengan persamaan:

c = Q/m. Δt

dengan:
c = kalor jenis (J/Kg . K)
Q = kalor (joule)
m = massa zat (Kg)
ΔT = perubahan suhu (Kelvin)

Setiap zat mempunyai nilai kalor jenis yang berbeda-beda. Berikut tabel nilai kalor jenis dari beberapa zat pada suhu 20° C. 
 merupakan salah satu bentuk energi yang sanggup berpindah dari benda satu ke benda lainnya Pengertian Kalor Jenis dan Contoh Soal serta Pembahasannya
Tabel kalor jenis beberapa zat
Untuk memantapkan pemahaman anda perihal konsep kalor jenis silahkan jawab soal pemahaman konsep di bawah ini. "Mungkin Anda pernah berjalan-jalan di atas pasir di pantai tanpa ganjal kaki pada siang hari dengan terik matahari, Anda akan mencicipi pasir kering akan terasa panas. Begitu Anda menginjakan air bahari maka anda akan mencicipi air bahari relatif lebih dingin. Padahal air bahari dan pasir pantai sama-sama terkena terik matahari. Kenapa air bahari terasa relatif lebih hambar daripada pasir pantai? Mana yang mempunyai kalor jenis lebih tinggi, air bahari atau pasir pantai?"

Jika sudah paham konsepnya, silahkan pahami teladan soal pemecahan problem di bawah ini dan kerjakan soal latihannya. Jawaban Anda boleh tulis di kolom komentar.

Contoh Soal
Sebuah cincin dari materi logam mempunyai massa 10 gr pada suhu 30 °C. Cincin tersebut dipanaskan dengan memberi kalor sejumlah 5 kal sehingga suhu cincin menjadi 47,5 °C. Hitunglah nilai kalor jenis cincin tersebut.

Penyelesaian:
Diketahui:
m = 4 gr
t1 = 34 °C
t2 = 57,5 °C
Q = 6 kal

Ditanyakan: c = ...?

Jawab:
Δt = t2 – t1
Δt = 57,5 °C – 34 °C
Δt = 23,5 °C

c = Q/m.Δt
c = 6 kal/(4 gr. 23,5 °C)
c = 0,064 kal/gr°C

Soal Latihan Kalor Jenis
Sepotong logam dijatuhkan dari atas sebuah gedung yang mempunyai ketinggian 225 m sampai menumbuk tanah. Kalor yang terjadi alasannya proses tumbukan dengan tanah sebesar 60% diserap oleh logam sehingga mengakibatkan suhunya naik 3°C. Jika percepatan gravitasi bumi 10 m/s2, maka hitunglah kalor jenis logam tersebut tersebut.
