## How do you type a long dash?

Let’s Do It! In Google Docs on Android or iOS, long-hold on the hyphen key on your keyboard for access to an en dash, em dash, and bullet character.

## What does R mean in physics?

r = radius. R = resistance. R = molar gas constant.

elapsed time

## What does B stand for math?

bisect bisector Base

## What does an em dash look like?

Em dashes differ from other hyphens and dashes not only in usage, which we will discuss shortly, but also in appearance. In fact, the em dash is named after its length—it’s about the same width as the capital letter M. Its alphabetical cousin, the en dash, is about the same width as the letter N.

## Is V initial or final velocity?

Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth’s gravitational force as the acceleration rate of an object.

## What is the time symbol?

Symbols for physical quantities and their international units

symbol quantity unit
V volume cubic meter
t time, duration second
T period, periodic time second
τ time constant second

## What does P MV stand for?

Linear momentum is defined as the product of a system’s mass multiplied by its velocity. In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object’s mass and also its velocity. Thus the greater an object’s mass or the greater its velocity, the greater its momentum.

## What is the difference between M and M in physics?

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is denoted using m or M. Weight is the measure of the amount of force acting on a mass due to the acceleration due to gravity.

## How do you make a long hyphen in Word?

Hold down the [Alt] key and type 0151 on the numeric keypad. Choose Symbol from the Insert menu, click the Special Characters tab, highlight the em dash, and click Insert.

## What does P in momentum stand for?

p is used because the word impetus formally in place ofmomentum comes from the latin, petere, hence we get p. That quantity is called as momentum. The popular equation for momentum according to the Newton’s law is that P=MV. Here, P stands for momentum, M stands for mass and V stands for velocity of an object.

## What is the use of en dash?

An en dash is a mid-sized dash (longer than a hyphen but shorter than an em dash) that is mostly used to show ranges in numbers and dates. It can also be used for clarity in forming complex compound adjectives.

## What is this symbol called in physics?

Physics Symbols for Some Basic Quantities:
