you would have to look up the formula and know what time and how fast and how far
Hello!
To calculate the speed(velocity) of a moving object, we can divide the displacement by the time interval in which the displacement occurred.
This is based off the formula:
v=d/t
Where v=velocity, d=total displacement, t=Time interval
Hope this helps. Any question please just ask. Thank you kindly.
Answer:
The second box
Explanation:
Work done is the force applied to move a body through a particular distance.
Work done = Force x distance
For the first box:
Weight = 12N
Distance = 1m
Work done = 12 x 1 = 12J
For the second box;
Weight = 1000N
Distance = 30cm = 0.3m
Work done = 1000 x 0.3 = 300J
The second box has a higher work done.
Answer:
The amount by which the second filter reduces the intensity of light emerging from the first filter is
z = 0.60
Explanation:
From the question we are told that
The angle between the axes is
The intensity of polarized light that emerges from the second filter is mathematically represented as
Where is the intensity of light emerging from the first filter
This means that the second filter reduced the intensity by z = 0.60
