Hi
Differentiate between luminous and non luminous objects.user
cee
The difference between luminous and non-luminous objects are -:
1. Luminous objects are the objects which emit light energy by themselves are called luminous objects. Whereas, non-luminous objects are the objects which does not emit light energy by themselves. 2) Luminous objects cause the sensation of light. Whereas, non-luminous objects do not cause the sensation of light. 3) Luminous objects are seen on their own. Whereas, non-luminous objects are seen due to luminous objects. 4) Examples of luminous objects are sun, candle, electric bulb. Whereas, examples of non-luminous objects are the moon, chair, plants.
Answer:
Explanation:
Objects that can emit light energy by themselves are known as luminous objects. These objects can cause the sensation of light.Objects that cannot emit light energy by themselves are known as non-luminous objects.These objects do not cause the sensation of light.

Electromagnetic waves from the sun reach the earth even though the space between us and the sun. Sound waves emitted by the sun cannot reach the earth. Explain why this difference?
Answer:
em waves do so because they require no medium to travel...space =vacuum)))
while sound waves that are longitudinal waves...require medium to travel......so in space it has vacuum.....it can't travel..

Whose atomic theory was the first to introduce the idea that all things are made from indivisible spheres called atoms and used evidence and research to back his findings? *
Answer:
Dalton's atomic theory
Explanation:
Dalton's atomic theory was the first to introduce the idea that all things are made from indivisible spheres called atoms and used evidence and research to back his findings. This theory was based on the law of constant composition and the law of conservation of mass. Also, this theory explains the matter in terms properties of atoms.

A wave has a wavelength of 0.02m and period of 8.0*10^-2 seconds. calculate it's speed. (showing working)
Answer:
[tex]v = 0.25m/s[/tex]
Explanation:
Given
[tex]\lambda = 0.02m[/tex] --- Wavelength
[tex]T = 8.0 * 10^{-2}s[/tex] --- Period
Required
Determine the velocity of the wave
This is calculated using:
[tex]v = \frac{\lambda}{T}[/tex]
[tex]v = \frac{0.02m}{8.0*10^{-2}s}[/tex]
[tex]v = \frac{0.02m}{8.0*0.01s}[/tex]
[tex]v = \frac{0.02m}{0.08s}[/tex]
[tex]v = 0.25m/s[/tex]
Hence, the velocity is 0.25m/s

________ 8. The pH of a solution is a measure of the concentration of H+ ions in it. TRUE OR FALSE
Answer:
False.
Explanation:
Potential of Hydrogen is the full form of PH.
Potential of Hydrogen tells about the acidity or basicity of the solution.
The pH of a solution is a measure of the concentration of hydrogen ions [tex](H+)[/tex] ions and hydroxide ions [tex](OH-)[/tex] in a solution.
So, the given statement is false.

A sixth grader moves down the hall at 1.2 m/s. When he sees a bunch of eighth graders coming, he
begins to run. After 3.2 s, he is moving at 3,6 m/s. What is his acceleration?
Answer:
0.75m/s^2
Explanation:
3.6-1.2=2.4 m/s (Change in velocity)
2.4/3.2=0.75 m/s/s or m/s^2

1. An elephant has a mass of 5,500 kg. What is the elephant's weight?
Write equation here:
Answer:
12125.42 Lbs.
Explanation:
The weight of the elephant is 53,900 N
The given parameters;
mass of the elephant = 5,500 kg
The weight of the elephant is calculated as;
Weight = mg
where;
m is the mass of the elephant
g is acceleration due to gravity = 9.8 m/s²
The weight of the elephant is calculated by substituting the given parameters;
Weight = 5,500 x 9.8 = 53,900 N
Thus, the weight of the elephant is 53,900 N

Transforme: a) 2 km em m b) 1,5 m em mm c) 5,8 km em cm d) 0,4 m em mm e) 27 mm em cm f) 126 mm em m g) 12 m em km
Answer:
a) 2000 m
b) 1500 mm
c) 580000 cm
d) 400 mm
e) 2.7 cm
f ) 0.126 m
g) 0.012 km
Explanation:
Transform
a) 2km to m
1 km = 1000m
hence : 2 km = 2 * 1000 = 2000 m
b) 1.5m to mm
1 m = 1000 mm
hence: 1.5 m = 1.5 * 1000 = 1500 mm
C) 5.8 km to cm
1 km = 100000 cm
hence ;5.8 km = 5.8 * 100000 = 580000 cm
D) 0.4 m to mm
1 m = 1000 mm
hence; 0.4 m = 0.4 * 1000 = 400 mm
E) 27 mm to cm
1 mm = 0.1 cm
hence ; 27 mm = 27 * 0.1 = 2.7 cm
F) 126mm to m
1 mm = 0.001 m
hence ; 126 mm = 126 * 0.001 = 0.126 m
G) 12m to Km
1 m = 0.001 km
hence ; 12 m = 12 * 0.001 = 0.012 km
