Answer:
Explanation:
For refraction through a curved surface , the formula is as follows
μ₂ / v - μ₁ / u = (μ₂ -μ₁ )/R , Here μ₂( air) = 1 , μ₁ ( water) = 4/3 , R = 1.95 m
u , object distance = - .465 m
1 / v + 1.333 / .465 = (1 -1.333 )/1.95
1 / v + 2.8667 = - .171
1 / v = - 2.8667 - .171 = - 3.0377
v = - .3292 m
= - 32.92 cm
image will be formed in water.
c ) magnification = μ₁v / μ₂u , μ₁ = 1.33 , μ₂ = 1 , u = 46.5 , v = 32.92 .
= (1.33 x 32.92) / (1 x 46.5)
= .94
size of image of teeth = .94 x 5
= 4.7 cm .
Explanation:
The reason for the more concentration of carbon dioxide in the atmosphere of Venus than in the Earth -
On the Earth , most amount of the carbon dioxide is in the ocean water and in sea sediments .
Considering Venus , in the planet Venus , there is no Ocean water , hence , carbon dioxide can not get dissolved into the water , hence , it is found in the atmosphere .
So , the escape velocity for carbon dioxide on Mars is smaller than Venus .
The gravitational force minus any contact forces acting on an object
The difference between the normal force and the gravitational force acting on an object
The sum of all the forces acting on an object in the same direction
The sum of all forces acting on an object in the same direction is described for the net force acting on an object.
Example : If two forces (2 kids pushing in the same direction to move the object big box) act on an object (big box) in the same direction, then the net force is equal to the sum of the two forces. If the kids pushed in the opposite direction, the net force will not occur.
Hence, Option D is the correct answer.

Calculate BE/A, the binding energy per nucleon, for 2H in megaelecton volts per nucleon
Answer:
0.88 MeV/nucleon
Explanation:
The binding energy (B) per nucleon of deuterium can be calculated using the following equation:
Where:
Z: is the number of protons = 1
N: is the number of neutrons = 1
: is the proton's mass = 1.00730 u
: is the neutron's mass = 1.00869 u
M: is the nucleu's mass = 2.01410
A = Z + N = 1 + 1 = 2
Now, the binding energy per nucleon for ²H is:
Therefore, the binding energy per nucleon for ²H is 0.88 MeV/nucleon.
I hope it helps you!
The binding energy per nucleon for 2H (deuterium) is 1.1125 MeV per nucleon.
The binding energy per nucleon, or BE/A, can be calculated by dividing the total binding energy of the nucleus by the number of nucleons. To calculate the BE/A for 2H (deuterium), we need to know the total binding energy and the number of nucleons in deuterium. The total binding energy of deuterium is approximately 2.225 MeV (megaelectron volts) and the number of nucleons is 2. Therefore, the BE/A for 2H is 2.225 MeV / 2 = 1.1125 MeV per nucleon.
