T = 40.0 N
angle = 25°
Trigonometric ratios:
sin(25°) = vertical component of the force / force
cos(25°) = horizontal component of the force / force
tan (25°) = vertical compoent of the force / horizontal component of the force.
From cos(25°) you can find the horizontal component of the force:
horizontal component of the force = force * cos(25°)
The force is the tension, 40.0 N.
horizontal component of the force = 40.0 N * cos (25°) = 36.25 N
Answer: 36.25 N
Search up criterion and look at the examples and then read it and then make it in your own words
Answer:
D) 1000 m/s
Explanation:
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Hope this helps.
