$ACTH$ is secreted by

$A$ plane passes through the point $A(2, 1, -3)$. If the distance of this plane from the origin is maximum,then its equation is:

The binding energy of deuteron $_1^2H$ is $1.112 \, MeV$ per nucleon and an $\alpha$-particle $_2^4He$ has a binding energy of $7.047 \, MeV$ per nucleon. Then in the fusion reaction $_1^2H + _1^2H \to _2^4He + Q$,the energy $Q$ released is ........ $MeV$.

$x-$ अक्ष के अनुदिश गतिमान एक तरंग का समीकरण $y(x, t) = 0.005 \cos(\alpha x - \beta t)$ द्वारा दिया गया है। यदि तरंग की तरंगदैर्घ्य $0.08 \ m$ और आवर्तकाल $2.0 \ s$ है,तो उपयुक्त इकाइयों में $\alpha$ और $\beta$ के मान क्या होंगे?
