Answer:
Explanation:he ball bounces back up with nearly the same speed as it hit. i don,t know if is right
B.) a magnetic material
C.) a nonmagnetic material
consider the forces on mass m₁ on the incline plane :
parallel to incline , force equation is given as
T - m₁ g Sin30 = m₁ a
T = m₁ g Sin30 + m₁ a eq-1
consider the force on mass m₂ on the incline plane :
m₂ g - T = m₂ a
T = m₂ g - m₂ a eq-2
Using eq-1 and eq-2
m₂ g - m₂ a = m₁ g Sin30 + m₁ a
inserting the values
(2.3 x 9.8) - 2.3 a = (3.7 x 9.8) Sin30 + 3.7 a
a = 0.74 m/s²
The speed of a wave is calculated by multiplying the frequency by the wavelength. For a wave with a frequency of 2Hz and a wavelength of 4m, the speed is 8m/s.
The subject of your question is Physics, specifically the behavior of waves. The speed of a wave can be calculated using the equation speed = frequency ×wavelength. Given that the frequency of your wave is 2Hz (hertz) and the wavelength is 4m (meters), we substitute these values into our equation.
Thus, the speed of the wave is 2Hz × 4m = 8 m/s. Therefore, the wave is moving at a speed of 8 meters per second.
