Answer:
Explanation:
As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

The final temperature of the gas given the data from the question is 1527 °C
<h3>Data obtained from the question</h3>
- Initial volume (V₁) = V
- Initial temperature (T₁) = 27 °C = 27 + 273 = 300 K
- Final volume (V₂) = 6V
- Final temperature (T₂) =?
<h3>How to determine the new temperature </h3>
The final temperature of the gas can be obtained by using the Charles' law equation as illustrated below:
V₁ / T₁ = V₂ / T₂
V / 300 = 6V / T₂
Cross multiply
V × T₂ = 300 × 6V
Divide both side by V
T₂ = (300 × 6V) / V
T₂ = 1800 K
Subtract 273 from 1800 K to express in degree celsius
T₂ = 1800 – 273
T₂ = 1527 °C

Answer:
4.9 x 10⁻⁴N
Explanation:
Given parameters:
Mass of the vertical strand of spiderweb = 5 x 10⁻⁵kg
Unknown:
Tension in the vertical strand = ?
Solution:
The tension is the vertical strand will be the weight of the strand.
Weight of strand = mg
m is the mass
g is the acceleration due to gravity = 9.8m/s²
Tension in the vertical strand = 5 x 10⁻⁵kg x 9.8m/s²
Tension in the vertical strand = 4.9 x 10⁻⁴N
Answer:
35870474.30504 m
Explanation:
r = Distance from the surface
T = Time period = 24 h
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
m = Mass of the Earth = 5.98 × 10²⁴ kg
Radius of Earth = 
The gravitational force will balance the centripetal force


From Kepler's law we have relation

Distance from the center of the Earth would be
