A progressive tax is a tax that imposes a lower tax rate on low-income earners compared to those with a higher income, making it based on the taxpayer's ability to pay. That means it takes a larger percentage from high-income earners than it does from low-income individuals.

Here, V = 30kV {tex} = 30 \times {10^3}V = 3 \times {10^4}V{/tex}
- hvmax = eV
{tex}{v_{\max }} = \frac{{eV}}{h} = \frac{{1.6 \times {{10}^{ - 19}} \times 3 \times {{10}^4}}}{{6.63 \times {{10}^{ - 34}}}}Hz{/tex}
{tex} = 7.24 \times {10^{18}}Hz{/tex} - {tex}{\lambda _{\max }} = \frac{c}{{{v_{\max }}}} = \frac{{3 \times {{10}^8}}}{{7.24 \times {{10}^{18}}}}m{/tex}
{tex} \Rightarrow {\lambda _{\max }} = 0.414 \times {10^{ - 10}} = m = 0.414\mathop A\limits^o {/tex}
= 0.414 nm

answer : 4.608 × 10^-8 N
charge on alpha particle , Q = +2e = 2 × 1.6 × 10^-19 C = 3.2 × 10^-19 C
charge on electron, q = -e = -1.6 × 10^-19C
seperation between electron and alpha particle , r = 1A° = 10^-10 m
from Coulomb's law,
magnitude of force between electron and alpha particle , F = K|q||Q|/r²
= 9 × 10^9 × (1.6 × 10^-19)(3.2 × 10^-19)/(10^-10)²
= (9 × 10^9 × 5.12 × 10^-38)/(10^-20)
= (9 × 5.12) × 10^(9-38+20)
= 46.08 × 10^-9 N
= 4.608 × 10^-8 N
hence, magnitude of force between electron and alpha particle is 4.608 × 10^-8 N. and nature of force is attractive because charge are in opposite in nature.

For women’s participation in sprots we have a look at ancient period. Regarding participation in the first modern olympic (1896 athens), there was no participation of women.
- Women participated first time in 1900 olympics. (22 women participated in)
-- In 1904 six women participated.
- And after 100 years in 2000 sydeny olympics 4069 women had participated.
-- In 2008 Beijing olympics 4637 women participated.
Participation in India
-- In 2000 karnam Malleshwari was the first woman who won bronze medal in Sydney Olympic from India.
-- In 1984 performance of P.T. Usha was very good in Athletics. -
- In 2012 london olympics Saina Nehwal and M.C. Mericom got bronze medal. In 2016, Rio Olympics, Sakshi Malik won bronze medal, P.V. Sandhu won silver medal where as Deepa Karmakar opened new dimesions in gymanastics. Over the past several decades the participation of women in sports in sports field has increased tremendously. But really, it is a matter of regret for all of us to know that sports is such a field where gender inequality in strongly evident. The general social environment has not only inhibited women from participation in sports but has also criticise them when they participate. Many people comment for women “Why don’t they stay in the kitchen where they belong”? But Now time has changed. Women are capable of changing society. Now the ideology suggests that women are participating in every sphere of life and prooving themselves globally.

For a first order reaction, rate constant,
{tex}k=\frac{2303}{t} \log \frac{[R]_{0}}{[R]}{/tex}
When {tex}t=t_{1 / 2^{\prime}}[R]=\frac{[R]_{0}}{2}{/tex}
{tex}t_{1 / 2}=\frac{2303}{k} \log \frac{[R]_{0}}{[R]_{0} / 2}{/tex}
{tex}t_{1 / 2}=\frac{2303}{k} \log 2=\frac{2303 \times 03010}{k}{/tex}
{tex}t_{1 / 2}=\frac{0693}{k}{/tex}
For a first order reaction, half-life period is constant. It is independent of initial concentration of the reacting species.
