Answer:
A peptic ulcer is a sore on the lining of your stomach or the first part of your small intestine (duodenum). If the ulcer is in your stomach, it is called a gastric ulcer. If the ulcer is in your duodenum, it is called a duodenal ulcer
Answer:
Binding Energy = 2.24 eV
Explanation:
First, we need to find the energy of the photon of light:
E = hc/λ
where,
E = Energy of Photon = ?
h = Plank's Constant = 6.626 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of light = 400 nm = 4 x 10⁻⁷ m
Therefore,
E = (6.626 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(4 x 10⁻⁷ m)
E = (4.97 x 10⁻¹⁹ J)(1 eV/1.6 x 10⁻¹⁹ J)
E = 3.1 eV
Now, from Einstein's Photoelectric Equation:
E = Binding Energy + Kinetic Energy
Binding Energy = E - Kinetic Energy
Binding Energy = 3.1 eV - 0.86 eV
<u>Binding Energy = 2.24 eV</u>
Answer:
The smaller ball (the tennis ball) will receive a much larger acceleration than the soccer ball of larger mass.
Explanation:
According to Newton's 2nd Law of motion,
(force equals mass times the acceleration imparted)
Since in this case we have the same force (50 N) applied to two different masses (one the tennis ball "m" which has smaller mass than the soccer ball of mass "M"), then the resultant accelerations will be different being the acceleration of the tennis ball (
) much larger than the acceleration imparted to the soccer ball (
), as can be seen from solving for the acceleration in the previous equation:
![F=mass*a\\a=\frac{F}{mass} \\a_t=\frac{F}{m} =\frac{10N}{m} \\a_s=\frac{F}{M} =\frac{10N}{M}](https://tex.z-dn.net/?f=F%3Dmass%2Aa%5C%5Ca%3D%5Cfrac%7BF%7D%7Bmass%7D%20%5C%5Ca_t%3D%5Cfrac%7BF%7D%7Bm%7D%20%3D%5Cfrac%7B10N%7D%7Bm%7D%20%5C%5Ca_s%3D%5Cfrac%7BF%7D%7BM%7D%20%3D%5Cfrac%7B10N%7D%7BM%7D)
Notice than when calculating the acceleration of the tennis ball (
), we divide 10N by a smaller number (m), than when we calculate the acceleration of the soccer ball (
), when we divide by a large number (M) resulting in a smaller quotient.
This one is also using pre-conventional moral reasoning.
