PLEASE HELP ASAP
77julia77 [94]

Answer:

<em>The first choice (32m/s) is the closest to the answer</em>

Explanation:

The magnitude of a vector is the distance between the initial and the end point of the vector.

Being Vx and Vy the horizontal and vertical components of the vector V respectively, the magnitude of V is calculated as:

\mid \vec{V} \mid =\sqrt{V_x^2+V_y^2}

The components of the velocity of the physics student's projectile launcher are Vx=28 m/s and Vy=15 m/s.

Calculate the magnitude of the velocity:

\mid \vec{V} \mid =\sqrt{28^2+15^2}

\mid \vec{V} \mid =\sqrt{784+225}

\mid \vec{V} \mid =\sqrt{1009}

\mid \vec{V} \mid =31.8 \ m/s

The first choice (32m/s) is the closest to the answer

At what temperature the semiconductor behaves like conductor?​
hammer [34]

Answer:

A semiconductor acts like an ideal insulator at absolute zero temperature that is at zero kelvin. It is because the free electrons in the valence band of semiconductors will not carry enough thermal energy to overcome the forbidden energy gap at absolute zero.
