Answer:

Explanation:

$a_{x}=0$ $v_{xo}= v_{o}cos(delta)t$ $a_{y}=-g$ $v_{yo}=sin$ θ

X-direction | Y-direction

$x=x_o+v_{xo}t$ ⇒ $x=v_{xo}cos(delta)t$ |

A 1-kg discus is thrown with a vertical velocity of 19 m/s at an angle of 35 degrees from a height of 1.94 m. Do not factor in a

Travka [436]

Answer:

Vertical velocity $V_y = 10.89 \ m/s$

Horizontal velocity $V_x = 15.57 \ m/s$

Explanation:

If a 1 -kg is thrown vertically with a velocity of 19 m/s at an angle of 35 °C from a height 1.94 m

The vertical and horizontal component can be resolved as:

$V_y = Vsin \theta \\ \\ \\\\V_x = Vcos \theta$

For Vertical component :

$V_y = V sin \theta \\\\V_y = 19 * sin 35 \\ \\ V_y = 19* 0..5736 \\ \\ V_y = 10.89 \ m/s$

For horizontal velocity

$V_x = V cos \theta \\\\V_x = 19 * cos 35 \\ \\ V_x = 19* 0.8192 \\ \\ V_x = 15.57 \ m/s$

To which series would the emitted light belong if an electron in a hydrogen atom underwent a transition from level n = 5 to leve

inessss [21]

So we want to know in which series would the emitted light belong if the electron in a hydrogen atom would go from the energy level n=5 to n=1. The correct answer is Lyman series. Complete Lyman series is from energy level n=6 to n=1. All of the wavelengths in the Lyman series are in the ultraviolet part of the electromagnetic spectrum.
