If the variance of the frequency distribution
is 3 , then $\alpha$ is equal to
Let $\vec{a}$ and $\vec{b}$ be two vectors such that $|\vec{a}|=\sqrt{14},|\vec{b}|=\sqrt{6}$ and $|\vec{a} \times \vec{b}|=\sqrt{48}$ Then $(\vec{a} \cdot \vec{b})^2$ is equal to
Density (p) of a body depends on the force applied (F), its speed (v) and time of motion (t) by the relation p = KFavbtc , where K is a dimensionless constant. Then
A particle is projected at an angle of 30° with ground with speed 40 m/s. The speed of the particle after 2 s is (use g=10 ms-2)
A block of mass 5 kg starting from rest pulled up on a smooth incline plane making an angle of 30◦ with horizontal with an affective acceleration of 1 ms−2. The power delivered by the pulling force at t = 10 s from the starts is W. [use g=10 ms−2] (Calculate the nearest integer value)
Proton and electron have equal kinetic energy, the ratio of de-Broglie wavelength of proton and electron is \(\frac{1}{x}\). Find x. (Mass of proton 1849 times mass of electron)
\(\frac{dy}{dx}\) + \(\frac{5}{x(1+x^5)}\)y = \(\frac{(1+x^5)^2}{x^7}\) If y(1) = 2, then the value of y(2) is:
