<span>The correct answer is option B. i.e UV Rays. The Ultra violet light is the part of electromagnetic light whose wavelength is less than the Visible light light. i.e. UV range is from 10 nm to 400 nm. UV light is invisible to the naked eye.</span>
In a distance vs time graph what does the slope represents the Velocity
The jogger's average speed 1.03 m/s
<h3>
The Speed and the Velocity of a Particle in a Circle</h3>
The speed of a particle is a circle will always be constant while the velocity will not. That is, velocity varies.
Given that a jogger jogs around a circular track with a diameter of 275 m in 14.0 minutes. First convert the minutes to seconds
Given parameters are;
- Time t = 14 minutes = 14 x 60s = 840 s
Speed V = 2πr ÷ t
V = ( 2 × π × 137.5 ) ÷ 840
V = 863.9 / 840
V = 1.028 m/s
Therefore, the jogger's average speed 1.03 m/s approximately

Answer:
brainly getting too strict smh...
Explanation:
<span>3. The attempt at a solution So basically what I did was divided into components. x: (3)(2000) = (3000)*v_x y: (v_vw)*(10000) = (3000)*v_y v_x, v_y is the velocity (after collision) in the x and y direction, respectively, of both cars stuck together (since it is an inelastic collision). v_vw is the initial velocity of the Volkswagen. Now what I did was that the angle is 35 degrees north of east. So basically made a triangle and figured that tan(35) = (v_y)/(v_x). This means (v_x)*(tan35) = v_y. Then, I simplified the component equations to get: x: 2 = v_x y: v_vw = 3*v_y Then plugging in for v_y, I got: v_vw = 3(2)(tan35) = 4.2 m/s as the velocity of the volkswagen. However, the answer key says 8.6 m/s. Could someone please help me out? Thanks Phys.org - latest science and technology news stories on Phys.org • Game over?
