it is basalt which is an igneous rock
Answer:
45°
Explanation:
Let there are two vectors, A and B. The angle between the two vectors is θ.
The dot product of two vectors is equal to the vector product of two vectors.
A B cosθ = A B Sinθ
tan θ = 1
θ = 45°
Thus, the angle between the two vectors is 45°
Answer:
by reducing friction.....
Answer:
An electric fan is considered to be a mixture of several simple machines. It includes the Wheel and Axle type, wedges, and the Inclined plane types. The blades of an electric fan are the inclined planes and the wedges.
When the frequency decreases the wavelength is further apart. When it increases its closer together. Think about a flat line when the frequency is low the wavelengths are wider. When its a high frequency the squiggly lines on the moniter are taller and thinner so the wavelengths are not as wide and not that far from each other depending on how high the frequency is.
