Answer:
These low-pressure gases prevent the filament inside the bulb from burning out; it also relieves some of the stress on the glass globe from normal atmospheric pressure, lessening the chance of glass breakage.
Explanation:
The distance between two protons to generate 950N of force is 0.49 X 10⁻¹⁵ m
<u>Explanation:</u>
Given:
Mass of man, m = 100 kg
Force between man and earth = 980 N
Charge of proton, q = 1.6 X 10⁻¹⁹C
Same force is generated between them
Distance between two protons, r = ?
According to Coulomb's law:

where,
k is Coulomb's constant
k = 9 X 10⁹ Nm²/C²
According to the question:

Solving the equation:

Therefore, the distance between two protons to generate 950N of force is 0.49 X 10⁻¹⁵ m
the color of light is called reflection
Answer:
a) = 10.22 rad/s
b) = 0.35 m
Explanation:
Given
Mass of the particle, m = 1.1 kg
Force constant of the spring, k = 115 N/m
Distance at which the mass is released, d = 0.35 m
According to the differential equation of s Simple Harmonic Motion,
ω² = k / m, where
ω = angular frequency in rad/s
k = force constant in N/m
m = mass in kg
So,
ω² = 115 / 1.1
ω² = 104.55
ω = √104.55
ω = 10.22 rad/s
If y(0) = -0.35 m and we want our A to be positive, then suffice to say,
The value of coefficient A in meters is 0.35 m
