Explanation

Hydrogen has an atomic weight of 1.00794u and accounts for 75% of the universe,

Thus making it the lightest and most abundant element in the universe.

Explanation

The James Webb Space Telescope (JWST) primarily uses infrared rays to capture images of distant objects in the univers

Explanation

In electric meters, current flowing through coils generates a magnetic field.

This magnetic field causes the aluminum disc inside the meter to rotate, measuring energy usage.

Explanation

Magnetic field lines around a straight current-carrying wire are circular, not straight.

They form concentric circles around the wire as per Right-Hand Rule.

Explanation

Pressure is inversely proportional to area (Pressure = Force / Area), and the pointed end has a much smaller area.

Thus, the same force produces greater pressure at the pointed end, allowing it to pierce surfaces easily.

Explanation

Explanation

 The dimensions of Planck's constant are the same as those of angular momentum. 

Planck's constant (h) is a fundamental constant in quantum mechanics

It relates the energy (E) of a photon to its frequency (ν) through the equation E = hν.

The dimensions of Planck's constant can be derived from this relationship,

And they are found to be the same as those of angular momentum

Explanation

Most low Earth orbit space stations, like the ISS, complete one full orbit in about 90 minutes.

This allows them to circle the Earth roughly 16 times per day.

Explanation

As two atoms come closer, attractive forces (like between electrons and nuclei) try to pull them together.

Simultaneously, repulsive forces (like between electron clouds or nuclei) also increase, balancing the interaction.

Explanation

MRI provides detailed images of soft tissues and tiny internal structures using strong magnetic fields and radio waves.

It is highly effective for diagnosing issues in the brain, spinal cord, joints, and internal organs.
