Distance is the total length covered = 2m + 3m = 5m
Displacement is his distance from original position.
Displacement = 2m + (-3)m. Representing the 3m walked back as -3.
Displacement = 2m - 3m = -1m.
So his displacement is 1m behind his original starting point.
Answer:
<h2>Ultraviolet Waves.</h2>
Explanation:
The Sun emits waves called "Solar Waves", which have a wavelengths between 160 and 400 nanometers. According to the electromagnetic spectrum, these waves are defined as Ultraviolet, which have a frequency around the order of 
, which is really intense and high energy.
Therefore, the answer is Ultraviolet Waves.
Answer:
A book containing information on various types of science related topics.
The X component of the vector is 11.5 while the Y component is 9.6.
<h3>What are the components of a vector?</h3>
We know that a vector must posses both magnitude and direction. Now the vector could be resolved into the vertical and the horizontal components of the mixture.
In resolving this vector;
X component = 15 cm cos 40 degrees = 11.5
Y component = 15 cm sin 40 degrees = 9.6
Thus the X component of the vector is 11.5 while the Y component is 9.6.

(a) PE = 0.016J
(b) PE = 1470J
Explanation:
Given:
Mass, m = 4 kg
distance, x = 0.12 m
Spring constant, k = 2.3N/m
Potential energy, PE = ?
We know:
On substituting the value we get:
(b)
Mass, m = 10kg
Height, h = 15m
Potential energy, PE = ?
Acceleration due to gravity, g = 9.8 m/s²
