Answer:
g / 16
Explanation:
T = 2π
angular frequency ω = 2π /T
=
ω₁ /ω₂ =
Putting the values
ω₁ = ω , ω₂ = ω / 4
ω₁ /ω₂ = 4
4 =
g₂ = g / 16

Answer:
Time, t = 6.34 hours.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
Therefore, making time the subject of formula;
Given the following data;
Displacement = 5200km
Average velocity = 820km/hr
Substituting into the equation, we have;
Time = 6.34 hours.
<em>Hence, it would take 6.34 hours for the airplane to reach its destination. </em>
In order to solve this, we will use the formula
where n is the index of infraction, c is the speed of light (3x10^8), and v is the medium in which the velocity is measured
solving for n,
n = (3x10^8)/(2.75x10^8) = 1.09
