# What is the difference between TM and R in the circle?

Use of the TM and SM symbols may be governed by local, state, or foreign laws and the laws of a pertinent jurisdiction to identify the marks that a party claims rights to. The federal registration symbol, the R enclosed within a circle, may be used once the mark is actually registered in the USPTO. Even though an application is pending, the registration symbol may not be used before the mark has actually become registered. The federal registration symbol should only be used on goods or services that are the subject of the federal trademark registration. PLEASE NOTE: Several foreign countries use the letter R enclosed within a circle to indicate that a mark is registered in that country. Use of the symbol by the holder of a foreign registration may be proper.

### What is the meaning of symbol R within a circle in a tablet strip?

The symbol capital R within a circle [Â®], or circled capital letter R, is the registered trademark symbol. This indicates that the product is registered with a national trademark office (ex: Registered, U.S. Patent and Trademark Office). If a trademark is not officially registered, then it will be marked with a superscript TM (in capitals).

### How does an ellipse compare with a perfect circle?

The question is a strange one as the answer depends on the context in which the question is asked. Graphically speaking: A line forming a perfect circle means that given a set point as the centre of the circle, the line will always be the exact same distance from the centre of the circle at any point along the line. An Ellipse on the other hand is a smooth closed curve that is symmetrical about…

### 5 What is the difference between select and project operations?

Select Operation : This opration is used to select rows from a table (relation) that specifies a given logic, which is called as a predicate. The predicate is a user defined condition to select rows of user's choice. Example : Consider an example to select all tuples of the loan Table (Relation) at KR Branch of a Bank. Here the relation considered is Loan and predicate is BR_NAME=K R Circle. BR_NAME Loan_no Loan_amount K R…

### What is the difference between a circle and a sphere?

A circle is two dimensional; a sphere is three dimensional Answer A circle is a simple shape consisting of points in a plane (flat surface) which are equidistant from a given point called the center. A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in three dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface…

### What is the distance between the points 4 and 1 and -3 and 6?

The distance between these two points is 8.6. I found this by finding the difference between the two x values and the difference of the two y values. The difference between the x value was found like this: 4- (-3)= 7 and the difference between the y values was found the same way: 1-6=-5. Now to find the length between the two points, you need to use Pythagorean theorem because a right angle triangle is…

### What is the length of the arc on a circle of radius r equals 5 yards intercepted by a central angle theta equals 70 degrees?

To work out the length of the arc on a circle, you need to work out the proportion of the full circle that the arc represents. This is the proportion of the circumference of the circle. The circumference of a circle is 2 times pi times radius or 2{pi}r A full circle has 360o so an arc created between 2 radii with an angle of ao between them has a length that is a/360 that…
