Answer:
Interstellar Dust
Explanation:
In the solar system Interstellar dust is a type of cosmic dust and unlike Interstellar gas they have large dust particles enabling them to block visible light. Unlike smoke and fog, they contain large number of closely packed clumps of atoms and molecules
Answer:
if it is at a speed of 12.5 m / s it would take 2 minutes
Explanation:
Answer:
17640J
Explanation:
Give mass m= 60kg
Height h =30m
Since the student is standing on the edge of a cliff , acceleration due to gravity g is 9.8m/s^2
The student’s gravitational potential energy can be found by the formula
mgh
That’s 60 x 9.8 x 30
= 17640J
Answer:
KE=2.3 x 10⁻¹⁹ J
Explanation:
Given that
λ = 544 nm
λ' = 485 nm
The kinetic energy KE given as
KE= E - Ф
Where
h= 6.626 x 10⁻³⁴
C=3 x 10⁸ m/s
Now by putting the values
KE=2.3 x 10⁻¹⁹ J
This is kinetic energy.
Heavy-duty cords will have a marking on the insulation such as letters which indicates its properties.
<h3>What are Heavy duty cords?</h3>
Heavy duty cords comprises of insulators which helps prevent cases of electric shock. There are usually letters written on them which indicates the nature of insulation and other properties.
For example, the "S" in "SO" stands for "Extra Hard Service and the "O" stands for oil resistant.
