Explanation

The SI unit of electric charge is the coulomb, represented by the symbol C.

One coulomb is the amount of charge that passes through a conductor carrying one ampere of current for one second.

It's also equal to the charge of about 6.24 quintillion electrons or protons.

Explanation

Magnesium deficiency can contribute to or exacerbate all of the following health issues:

• Painful joints: Magnesium helps regulate inflammation and muscle function, and deficiency can lead to joint pain and stiffness.
• Osteoporosis: Magnesium is essential for bone mineralization and density; deficiency can increase the risk of osteoporosis and fractures.
• Memory loss: Magnesium plays a role in neuronal function and synaptic plasticity; deficiency has been linked to cognitive impairment and memory loss.
• Diabetes: Magnesium helps regulate insulin sensitivity and glucose metabolism; deficiency can increase the risk of developing type 2 diabetes.

Explanation

Refraction is the bending of light as it passes from one medium to another (e.g., air to water).

This occurs due to a change in the speed of light in different media.

Explanation

The SI unit of radioactivity is becquerel (Bq).

Curie is a non-SI unit, with 1 curie equal to 37 billion Bq.

Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration)

It is the process by which an unstable atomic nucleus loses energy by radiation.

Three of the most common types of decay are:

• Alpha
• Beta
• Gamma decay

Explanation

In simple harmonic motion (S.H.M), the restoring force is minimum at Mean position. 

The restoring force is directly proportional to the displacement from the mean position.

At the mean position, the displacement is zero, meaning the restoring force is also zero at that point.
