Answer:
The tension in the rope is 49.66 N.
Explanation:
Given that,
Mass of bucket m= 23.0 kg
Diameter = 0.300 m
Mass of rope M= 13.0 kg
Height = 10.5 m
Suppose we need to find the tension in the rope while the bucket is falling.
We need to calculate the acceleration
Using balance equation
..(I)
We need to calculate the tension in the rope
Using formula of tension
....(II)
Put the value of T in the equation (I)
Put the value into the formula
Now, put the value of a in equation (II)
Hence, The tension in the rope is 49.66 N.
Answer:
1.45
Explanation:
Refractive index of the liquid is given as;
Refractive index =
But,
speed =
Since a certain light of specific wavelength was used during the same time, let the time be represented by t.
So that;
speed of light in vacuum =
speed of light in the liquid =
Refractive index = ÷
= x
Refractive index =
= 1.4536
= 1.45
The refractive index of the liquid is 1.45.
Answer: 1. The movie one is virtual and the bathroom mirror is real
2. The image is distorted in a way
3. Behind the spoon
Explanation:
Answer:
distance traveled is 15 mi
displacement is 5 mi
Explanation:
Distance takes time into account and adds up all the tiny displacements during the entire period of the trip.
Displacement ignores time and looks only at the change in position from the starting point to the ending point.
