Explanation

The material with the lowest permeability among the options listed is a diamagnetic material.

Explanation

The perpendicular distance from the point (3,-4) to the line 3x^2 − 4x + 10 = is 7.

Explanation

Increasing the proportion of reactants which have enough energy to overcome the activation energy: At a higher temperatures, more reactants have enough energy to overcome the activation energy. This increases the frequency of successful collisions so the rate increases.

Explanation

According to Newton's 2nd law, the object's acceleration and centripetal force are in the same direction.

Explanation

• The idiom "put a spoke in my wheel" means to hinder or obstruct someone's progress or plans.
• It is a metaphorical expression that comes from the idea of putting a spoke in a wheel, which would prevent it from turning and make it difficult to move forward.

Explanation

• High-speed electrons, such as those emitted in beta decay or used in electron microscopy, have wavelengths in the range of 10^-15 meters to 10^-12 meters.
• This is due to their high energy and momentum, which corresponds to a short wavelength according to the de Broglie hypothesis.

Explanation

Electrons are accelerated by voltages up to 10^9 V in order to find the internal structure of a nucleus.

Explanation

Pungent means تیکھی

Sharp smell means تیز بو

Explanation

Uni negative ion is exothermic due to strong nuclear attraction and no already electron-electron repulsion.

Explanation

• Adrenaline requires a cell surface receptor for its action.
• Adrenaline, also known as epinephrine, acts through cell surface receptors called adrenergic receptors to exert its physiological effects.
