To solve this problem we will apply Newton's second law and the principle of balancing Forces on the rope. Newton's second law allows us to define the weight of the mass, through the function
Here,
m = mass
a = g = Gravitational acceleration
Replacing we have that the weight is
Since the rope is taut and does not break, the net force on the rope will be zero.
Therefore the tensile force in the rope is 98N
Answer:
The tension is 14 N
Explanation:
For this problem we have to use newton's law, so:
The second string is connected to the mass of 8 kg, but the mass of 8 kg is connected to the mass of 20kg, so we can say that the second string is handling the two masses. so:
Answer:
Explanation:
We know that there is a relation between the speed of light ,frequency and wavelength.This relation can be given as where v is speed of light
is frequency of light
is wavelength of light
In first case we have given λ=655 nm
so using formula
Hz
In second case we have wavelength 515 nm so by using above formula
In third case we have wavelength 475 nm
so
