Option (c) : +f
Explanation:
Sign convention is based on cartesian system with Optical Centre as vertex, therefore, focal length of a convex mirror is +ive.
The actual mass of a 1 cm² piece of copy paper is determined as 0.0074 g.
<h3>Area of the sheet of paper in square centimeters</h3>
Area = Length x Width
Area = (11 x 2.54 cm) x (8.5 x 2.54 cm)
Area = 603.22 cm²
<h3>Actual mass of the sheet of paper</h3>
Mass = area density/area
Mass = (4.5 gcm²)/(603.22 cm²)
Mass = 0.0074 g
The complete question is below:
A sheet of 8.5 inch by 11inch paper has a mass of 4.50 grams one square centimeter , 1cm2 of that sheet of paper will have a mass closets to ____grams ( (hint use 1inch = 2.54 centimeters and area = length times)

It's B. Water can have a very big effect on the atmosphere.
... We know that there are no forward or backward forces on the object, because its forward speed is constant.
... The left and right forces on the object add up to zero, so it won't begin to move left or right. It'll just keep on with the same 20 m/s forward motion.
... Its velocity after 2 seconds, 10 seconds, or an hour, will still be 20 m/s forward.
