Fusion is the energy source of stars. The energy that is being released from the gas collapse into a protostar causes the center of the protostar to become extremely hot. Once the core is hot enough, nuclear fusion commences. The fusion reaction is a very structured process, releasing a huge amount of energy.

Contrast the image formed by a convex lens when an object is located more than twice the focal length from the lens with the ima
matrenka [14]

Answer:

\begin{array}{lll}&\underline{Object \ at \ more \ than \ 2\times Focus} & \underline{Object   \ at \ less \ than \  Focus}\\\\1.  \ Location \ of \ image &Same \ side \ as \ object&Opposite \ side \ of \ lens\\\\2. \ Orientation \ of \ image &Inverted&Upright\\\\3. \ Type \ of \ image&Real&Virtual\\\\4. \ Size\ of \ image&Smaller \ than \ object& Larger \ than \ object\end{array}

Explanation:

The location, orientation, size, and type of image formed by a convex lens are related to the position of the image location in front of the lens

Object >2·F = The image formed by a convex lens when the object is located more than twice the focal length from the lens

Object < F = The image formed by the convex lens when the object is located between the lens and the focal length

\begin{array}{lll}&\underline{Object \ > \ 2\cdot F} & \underline{Object  < F}\\\\1.  \ Location \ of \ image &Same \ side \ as \ object&Opposite \ side \ of \ lens\\\\2. \ Orientation \ of \ image &Inverted&Upright\\\\3. \ Type \ of \ image&Real&Virtual\\\\4. \ Size\ of \ image&Smaller \ than \ object& Larger \ than \ object\end{array}

A stone is launched from the ground, at a 70° angle, with an initial velocity of 120 m/s.
zavuch27 [327]
<span>A) x = 41t
    The classic equation for distance is velocity multiplied by time. And unfortunately, all of your available options have the form of that equation. In fact, the only difference between any of the equations is what looks to be velocity. And in order to solve the problem initially, you need to divide the velocity vector into a vertical velocity vector and a horizontal velocity vector. And the horizontal velocity vector is simply the cosine of the angle multiplied by the total velocity. So H = 120*cos(70) = 120*0.34202 = 41.04242 So the horizontal velocity is about 41 m/s. Looking at the available options, only "A" even comes close.</span>
