Speed, v = fλ.
Where f is the frequency in Hertz, wavelength is in meters.
Speed, v = 2*5 = 10
Speed = 10 m/s.
Answer:
Explanation:
The man is moving on a circular path . The reaction of wall is providing centripetal force .so
R = mv² / r
Frictional force = μR where μ is coefficient of friction
= μ x mv² / r
Frictional force = μ x mv² / r
Answer:
<span>Plants that have been buried</span>
Explanation :
According to the provided graph it is showing that the plant dies and buried before microbes which make them decay , then heat and pressure in Earth's crust for millions of years which can turn into coal,gas, or oil which then is extracted and burnt to create carbon dioxide in which a plant takes it in and the process repeats
Answer:
Explanation:
From the position coordinates given , it appears that the ball moves simultaneously along x and y direction.
Displacement along x direction in one second = 4.4 - 1.8 = 2.6 m
So velocity along x direction V_x =
Similarly velocity along y direction V_y(1) =
In the next phase velocity changes both in x and y direction.
velocity in x - direction V_x(2) = [tex]\frac{2}{s}[/tex
Velocity in Y- direction V_y(2) = [tex]\frac{3.1}{s}[/tex
Acceleration in x direction = change of velocity in x direction
= ( 2 - 2.6 ) = -.6 m s⁻²
Acceleration in y direction = ( 3.1 - 2.6 ) = 0.5 m s⁻²
Total acceleration =\sqrt{( -.6 )² + ( .5 )²}
= .78 ms⁻²
