Energy released during an earthquake travels in the form of waves<span> around the Earth. Two types of seismic </span>wave<span> exist, </span>P<span>- and </span>S-waves<span>. They are different in the way that they travel through the Earth. ... They are transverse </span>waves<span> which mean the </span>vibrations<span> are at right angles to the direction of travel.</span>
There are 123.56 of them. (rounded)
Answer:
70 N
Explanation:
Draw a free body diagram of the boy. There are four forces:
Weight force mg pulling down,
A 300 N normal force pushing up,
A 75 N applied force pulling right,
and a 5 N friction force pushing left.
The boy's acceleration in the y direction is 0, so the net force in the y direction is 0.
The net force in the x direction is 75 N − 5 N = 70 N.
Answer:
The answer is "C. 3.0 ohms".
Explanation:
Ohm's law states the following:,
V = IR
where:
Voltage (V) = 1.5 volts × 4 batteries = 6.0 volts
Current (I) = 2.0 amps
Resistance (R) = ? ohms
To solve for Resistance (R) the equation must be rearranged this way:
R = V / I
Then, the variables must be replaced with the known values:
R = 6.0 volts / 2.0 amp
R = 3.0 ohms
The answer is C. 3.0 ohms.

P.D: I got it right on PLATO
<span>When two or more waves meet, they interact with each other. The interaction of waves with other waves is called wave interference. Wave interference may occur when two waves that are traveling in opposite directions meet. The two waves pass through each other, and this affects their amplitude.</span>
