Answer:
d. the atomic number remains the same.
Explanation:
First at all it's important to know how to read nuclear information
X is the atomic symbol, A the mass number and Z the atomic number of the element.
Gamma rays emitted on gamma decay are characterized as
If we write the nuclear equation for the decay, we have that:
The sum of the mass numbers and atomic numbers on the right side has to be equal to the left side numbers of the equation, that means the mass number and the atomic number remains the same for the resulting atom to preserve the equality.
Answer:
Mass of the pull is 77 kg
Explanation:
Here we have for
Since the rope moves along with pulley, we have
For the first block we have
T₁ - m₁g = -m₁a = -m₁g/4
T₁ = 3/4(m₁g) = 323.4 N
Similarly, as the acceleration of the second block is the same as the first block but in opposite direction, we have
T₂ - m₂g = m₂a = m₂g/4
T₂ = 5/4(m₂g) = 134.75 N
T₂r - T₁r = I·∝ = 0.5·M·r²(-α/r)
∴
Mass of the pull = 77 kg.
Answer:
A) 58 degree
Explanation:
When unpolarized light passing through first polarizer then the intensity of light becomes half as it will get polarized
So let say the intensity of unpolarized light is "Io" then after passing through first polarizer the intensity will become half
Now when this polarized light passing through another polarizer then the intensity of light is given by Malus law
As per Malus law if the angle between two polarizer axis is inclined at some angle
then it is given as
