Answer:
the ratio of the kinetic energy of an electron to that of a proton if their wavelengths are equal is 1835.16 .
Explanation:
We know, wavelength is expressed in terms of Kinetic Energy by :
Therefore ,
It is given that both electron and proton have same wavelength.
Therefore,
.... equation 1.
.... equation 2.
Now, dividing equation 1 by 2 .
We get ,
Putting value of mass of electron = and mass of proton =
We get :
Hence , this is the required solution.
Answer:
c will have the largest charge
Explanation:
because more lines are coming more line means more foce is required
Answer:
Ping Pong ball move at velocity 160.4 m/s
Explanation:
given data
mass m1 = 7 kg
velocity v1 = 3 m/s
mas m2 = 2.45 g = 2.45 × kg
same kinetic energy
to find out
How fast Ping Pong ball move (v2)
solution
we know same KE
so
...........1
so v2 will be
v2 = .............2
put here value in equation 2 we get v2
v2 =
v2 = 160.4
so Ping Pong ball move at velocity 160.4 m/s
Answer:
L = 94.2 ft
n ≈ 5
Explanation:
d = 500 ft
R = 15 ft
The pony walks in one ride around the circle:
L = 2*π*R = 2*3.14*15 ft = 30*π ft = 94.2 ft (One ride around the circle).
In order to determine how many times (n) can the pony give a ride before it needs a drink, we can apply
n = d / L = 500 ft / 94.2 ft = 5.308 ≈ 5
When calcium oxide reacts with water, then it combines with water and forms calcium hydroxide.
CaO + H2O → Ca(OH)2
Calcium oxide + Water → Calcium hydroxide
Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either react with water to form a base
