Answer:
Final velocity, v = 0.28 m/s
Explanation:
Given that,
Mass of the model,
Speed of the model,
Mass of another model,
Initial speed of another model,
To find,
Final velocity
Solution,
Let V is the final velocity. As both being soft clay, they naturally stick together. It is a case of inelastic collision. Using the conservation of linear momentum to find it as :
V = 0.28 m/s
So, their final velocity is 0.28 m/s. Hence, this is the required solution.
Work done = force x distance
Work done = 50 x 2
Work done = 100J
Answer:
Explanation:
The question in english is:
A ray of light falls under an angle of incidence of 30 degrees on a flat surface that separates two transparent materials with indexes of refractions 1.60 and 1.40, respectively.
Calculate the angle of refraction (from the environment with the lower index of refraction)
<u>Solution</u>
According to Snell's Law :
Where:
is the first medium index of refraction
is the second medium index of refraction
is the angle of the incident ray
is the angle of the refracted ray
We need to find from the equation above,
<h2>Therefore, the angle of refraction is 34.84°</h2>

Answer:
Length of the pendulum will be 3.987 m
Explanation:
We have given time period of the pendulum T = 8 sec
Acceleration due to gravity
We have to find the length of the simple pendulum
We know that time period of the simple pendulum is given by
So length of the pendulum will be 3.987 m
