Answer:
<h2>22500 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 1500 × 15
We have the final answer as
<h3>22500 kg.m/s</h3>
Hope this helps you
By firing electrons from a cathode gun at a known velocity through an electric field of a known strength, J.J Thomson was able to observe how much the field deflected the beam. With a mass-to-charge ratio calculated, he could determine that the mass of the electron was not significantly heavy (in fact almost nothing compared to the proton or neutron)
To solve this exercise, it is necessary to apply the concepts on the principle of superposition, specifically on constructive interference,
Constructive interference (light spot) is defined by
Where,
m = The integer m is called the interference order and is the number of wavelengths by which the two paths differ.
d = Distance
For smaller angles ,
From the trigonometric properties it is understood that so the is - in this case - the length measured vertically by reason of distance, that is
Re-arrange to find y,
Replacing our values
PART B) To calculate the intensity it is necessary to find the angle between the previously calculated height and distance in order to calculate the phase angle, in other words,
Therefore phase angle is
The intensity formula would then be given by,
Chemical weathering weakens the outer surfaces of rocks and its primary agent is water. Mechanical weathering is carried out by impact or attrition by water and air.
Both of these forms of weathering combine and cause rocks to obtain a spherical shape.The concentric layers of rock are combined to form structures known as saprolite.
If the motorcycle can go from 0 to 50mph in 3 seconds the person is describing the motorcycle's acceleration.
