Answer:
Transverse wave- Back and forth at right angles to the direction of the wave arrow.
longitudinal wave- bask and forth in the direction of the motion of the motion of the wave.
electromagnetic wave- two alternating waves moving at right angles to each other.
Explanation:
In a longitudinal wave, the particles vibrate at right angles in reference to the wave motion.
In a transverse wave, the particles vibrate parallel to the wave motion
Electromagnetic waves occur as a result of the interaction between two waves and are normally transverse in nature.
There will not be enough momentum from the first hill to cross another hill if he same or larger size because of the way potential energy and kinetic energy works it will not be able go as high as it could go on he fist hill.
Answer:
-2π ≤ ∅ ≤ 3π/2
0 ≤ ∅ ≤ π/2
Explanation:
In simple harmonic motion, the displacement and velocity vectors are as follows:

where ∅ is the phase angle. At t = 0, the initial displacement and velocity are

According to two equations, we need to find the ∅ values which makes both cosine and sine terms positive.
So, ∅ is in the range: [-2π, -3π/2] and [0,π/2]
Answer:
The answer is Both types of government work well in countries with large populations.
Explanation:
Answer:
Option C.
The gravitational force between two objects is proportional to the product of their mass and inversely proportional to the distance between the two masses.
The formula of the gravitational force
between two objects of mass
and
that are separated by a distance r is:

Where G is the gravitation constant.
You can see that as the masses increase, it also increases the gravitational force. But as the distance between the masses increases, the gravitational force decreases.
Therefore the correct option is the C "mass increases or distance decreases"
