Let $ f(x) = |x - 3| + |x + 5| $ and $ A = \left\{ a \in \mathbb{R} / \lim_{x \to a} \frac{f(x) - f(a)}{x - a} \text{ exists} \right\} $. Then the number of real numbers which are in $ [-8, 3] \cup [5, \infty) $ but not in $ A $ is

If $ A = (2, 3) $ and $ B = (-4, 5) $ are two fixed points, then the locus of a point $ P $ such that the area of $ \triangle PAB $ is 12 square units is

In a city it is found that 10 accidents took place in a span of 50 days. Assuming that the number of accidents follow the Poisson distribution, the probability that there will be 3 or more accidents in a day in that city, is

Let $ f: \mathbb{R} \rightarrow \mathbb{R} $ be a function defined by $ f(x) = \frac{2x+1}{3} $. If $ \alpha $ is an element in the domain of $ f $ whose image is $ \frac{1}{\alpha} $, then the sum of all possible values of such $ \alpha $ is

The process of converting a precipitate into colloidal solution is known as

In a Young’s double slit experiment, a laser light of wavelength 560 nm produces an interference pattern with consecutive bright fringes’ separation of 7.2 mm. Now another light is used to produce an interference pattern with consecutive bright fringes’ separation of 8.1 mm. The wavelength of the second light is:

Which element of group 14 decomposes steam to form dioxide and dihydrogen gas?

Total number of angular nodes of orbitals associated with third shell $ (n=3) $ of an atom is:

An oxide of chlorine with water gives the strongest acid. The ratio of chlorine and oxygen in its formula is:

A message signal of frequency 14 kHz is used to modulate a carrier of frequency 900 kHz. Then, the frequencies of the sidebands are:

The resultant resistance between $ A $ and $ B $ in the given figure is:

Switch $ S $ is closed. Now the switch is opened and the free space between the plates of the capacitors is filled with a dielectric of dielectric constant 3. The ratio of total electrostatic energy stored in the capacitors before and after the introduction of the dielectric is:

The temperature of the earth without the greenhouse effect will be: Options:

A solid sphere and a solid cylinder roll down without slipping along an inclined plane. If they start from rest from the top of the inclined plane, the ratio of the velocities of the solid sphere and solid cylinder when they reach the bottom of the inclined plane is:

The potential difference across the ends of a conductor is $ (50 \pm 3) $ V and the current through it is $ (5 \pm 0.1) $ A. The percentage error in the measurement of the resistance of the conductor is: Options:

Assertion (A): If $ f(x) $ is not continuous at $ x = a $, then it is not differentiable at $ x = a $. Reason (R): If $ f(x) $ is differentiable at a point, then it is continuous at that point.

If the planes $ 2x + 3y + 4z + 7 = 0 $ and $ 4x + ky + 8z + 1 = 0 $ are parallel, then the equation of the plane passing through the point $ (k, k, k) $ and having the direction ratios of its normal as $ (k-1, k, k+1) $ is
