Answer:
1. You should always feel pain when stretching
Explanation:
This statement is false because you shouldn't feel pain when stretching.
Answer:
A) An interference pattern
Explanation:
the two slit experiment is key to understand the microscopic world. The wave-like properties of light were demonstrated by the famous experiment first performed by Thomas Young in the early nineteenth century. In original experiment, a point source of light illuminates two narrow adjacent slits in a screen, and the image of the light that passes through the slits is observed on a second screen.
<u>Key Points</u>
- waves can interfere, for light this will make a series of light and dark bands
- matter particles, such as electrons, also produce interference patterns due to their wave-like nature
- so with a high flux of either photons or electrons, the characteristic interference pattern is visible
Answer:
We have to take the two axes of coordinates, the X axis & the Y axis, and perform the equation of sum of forces on each of the X & y axes. In order to find the value of the respective forces. We can also perform summations of moments around a given point to find unknowns in deduced equations.
Explanation:
A free body diagram gives us a summary of the forces acting on a body. These forces can be equal to zero. Or equal to the product of its mass by acceleration.
Although in some cases special attention should be paid to the movement of the body by such forces, for example if the movement is at constant speed, the acceleration will be equal to zero. Therefore the sum of forces will be equal to zero when the speed is constant.
Finally we have to take the two axes of coordinates, the X axis & the Y axis, and perform the equation of sum of forces on each of the X & y axes. In order to find the value of the respective forces.
We can also perform summations of moments around a given point to find unknowns in deduced equations.
In the attached image we can see a beam which is subjected to loads, and performing a summation of moments around the pivoting point equal to zero (the beam is in balance) we can find the value of force F.
Answer:
6 and 14 respectively
Explanation:
proton number = atomic number
mass number = proton number + neutron number
since
- p.n = a.n = 6
- m.n = p.n + n.n
- m.n = 6 + 8 = 14
- m.n = 14
Solution:
54 / 9 = 6 boxes.
