Answer:
a = 7.5 m / s²
Explanation:
For this exercise let's use Newton's second law, let's create a coordinate system with the x axis parallel to the plane and the y axis perpendicular to the plane
Y axis
N - W cos θ = 0
N = mg cos θ
X axis
W sin θ = m a
mg sin θ = m a
a = g sin θ
let's calculate
a = 9.8 cos 40
a = 7.5 m / s²

Answer:68m/s
Explanation:
Frequency=17Hz
Wavelength=4metre
Wave speed=frequency x wavelength
Wave speed =17 x 4
Wave speed =68m/s
Answer:
Potential energy because it is not moving
Explanation:
A book on the edge of Sammy's desk will have a potential energy because it is not moving.
Potential energy is the energy due to the position of a body.
- This form of energy is the energy found in a body at rest.
Potential energy = mxgxh
m is the mass of the body
g is the acceleration due to gravity
h is the height of the body
