To solve this problem it is necessary to apply the concepts related to the kinematic equations of linear motion. For this purpose, we will use the definition of the speed equivalent to the displacement made by a body in a fraction of time. From this definition we will relate the time and distance variables required in the problem
Here,
v = Velocity
d = Distance
t = Time
With our values we have,
The speed of light is the speed at which waves move, therefore using the same formula above, but to find the distance we would have
Here,
c = Speed velocity
We have then,
Therefore the distance between the Earth and the spaceship is
When we give energy to the electrons, or when electrons gain energy, it jumps into the outer orbital !
Answer:
The mass of the string and new frequency are 20.78 g and 40.0 Hz.
Explanation:
Given that,
Frequency = 50.0 Hz
Mass per unit length = 0.115 g/m
String length = 210.4 cm
Number of loops = 5
We need to calculate the mass is hung from the string
Using formula of frequency
Where, f = frequency
M = mass per unit length
T = tension
Put the value into the formula
We need to calculate the new frequency for 4 loops
Using formula of frequency
Hence, The mass of the string and new frequency are 20.78 g and 40.0 Hz.
