Answer:
radio waves, microwaves, infrared, visible, UV, X-rays, gamma rays
Explanation:
Electromagnetic waves consist of oscillating electric and magnetic fields which vibrate in a direction perpendicular to the direction of motion of the wave (transverse wave). Electromagnetic waves travel in a vacuum with a speed of (speed of light), and they are classified into 7 different types according to their wavelength.
From longer to shorter wavelength, these types are:
Radio waves (wavelength > 30 cm)
Microwaves (30 cm - )
Infrared ()
Visible light (750 nm - 380 nm)
UV radiation (380 nm - 8 nm)
X-rays (8 nm - 6 pm)
Gamam rays (< 6 pm)
Answer:
Mass = 30.46 kg
Explanation:
Given the following data;
Spring constant = 45 N/m
Acceleration = 1.3 m/s²
Extension = 0.88 m
To find the mass of the box;
First of all, we would determine the force acting on the spring.
Force = spring constant * extension
Force = 45 * 0.88
Force = 39.6 N
Next, we find the mass using Newton's second equation of motion.
Force = mass * acceleration
39.6 = mass * 1.3
Mass = 39.6/1.3
Mass = 30.46 kg
Answer:
C)
Explanation:
The most common way of measuring homelessness is through so-called 'point-in-time' estimates of people who are sleeping in shelters or on the streets. These are figures that are intended to reflect the number of people who are homeless 'on any given night'.
