Answer: It'd be 14.
Explanation:
The formula for this equation would be (57f-32)×5/9 which is equal to 13.889; and rounding that to the whole number would be 14.
We know, acceleration is the change of velocity by time. Velocity is the speed of an object which also indicates the direction. Hence, acceleration is both dependant upon the speed as well as the direction. So, if an object is moving at a constant speed in a changing direction, the acceleration will also change. It will not be zero. An example is that of uniform circular motion. Answer:
if an object is moving at a constant speed in a changing direction, the acceleration of the object will not be zero.

Explanation:
its an alkali metal placed under sodium and its over rubidium, its also the first element of period 4
A globe sitting on the desk can't demonstrate the speed of axial rotation or the speed of orbital revolution.
The correct option is B. Sunglasses are designed to block polarized light. If you are driving toward the sun, most of the sun's glare will be coming to you horizontally, thus, the best sunglasses to wear is the one, that will block the horizontal glare and allow only the vertical glare to pass through.
