Answer:
The time taken for the alpha particle is 5.301x10⁻⁷s
Explanation:
The centripetal force is equal:
The magnetic force is equal:
Matching both expressions:
Where
m = 6.64x10⁻²⁷kg
v = 4.8x10⁵m/s
B = 0.123 T
q = 1.6x10⁻¹⁹C
The time taken for the alpha particle is:
The forces that were exerted during the air resistance was the gravity.
<u>Explanation:</u>
Air resistance is the frictional power air applies against a moving article. As an article moves, air opposition backs it off. The quicker the article's movement, the more prominent the air obstruction applied against it.
The force acting upon the objects dropped in the air was air resistance and gravity. The force acting upon the objects dropped in the vacuum was gravity only.
Answer:
If you haven’t read about the shark found swimming in and out of a segment of an undersea volcano, then you really need to get up to date.
Explanation:
Answer:
Delta pressure = 45938[Pa]
Explanation:
This is a classic bernoulli equation problem, but first we must find the velocity at both ends of the pipe, knowing the diameters of each end.
Now we can calculate the two velocites VA and VB
Using the bernoulli equation we have:
Where ro = density of water = 1000[kg/m^3]
The periodic table shows the atomic number ( # of protons) and average atomic mass (weight of protons and neutrons combined). You can subtract the number of protons from the atomic mass of that element to find number of neutrons.
