A stone is thrown straight up. While the stone is rising: Group of answer choices its acceleration is upward and decreasing its acceleration is upward and constant its acceleration is upward and increasing its acceleration is zero None of the available answers are correct. its <u>acceleration </u><u>is zero</u>

<h3>What is acceleration ?</h3>

The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force acting on an object determines the direction of its acceleration.

According to Newton's Second Law, the amount of an object's acceleration depends on two factors: the net balance of all external forces acting on the object; the magnitude of the acceleration is directly proportional to the net resulting force. For instance, when a vehicle begins at rest (zero velocity in an inertial frame of reference) and moves straight ahead at increasing speeds, it is accelerating in the direction of travel.

Lightning flashes one mile (1609 m) away from you. How much time does it take the light to travel that distance?
hichkok12 [17]

Answer:

t=5.36\times 10^{-6}\ s

Explanation:

Given that,

Lightning flashes one mile (1609 m) away from you.

We need to find the time it take the light to travel that distance. Let the time be t. We know that,

speed = distance/time

t=\dfrac{d}{v}\\\\t=\dfrac{1609}{3\cdot10^{8}}\\\\=5.36\times 10^{-6}\ s

So, the required time is 5.36\times 10^{-6}\ s

If this resolving power is diffraction-limited, to what effective diameter of your eye's optical system does this correspond? us
ZanzabumX [31]
"This resolving power" was obviously stated earlier, somewhere before the point where you started copying. With no resolving power specified, there's actually no question, and so no answer.

What does E=MC2 mean
mel-nik [20]

Answer: E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
