Clock speeds are typically measured in MHz (megahertz or millions of pulses per second) or GHz (gigahertz or billions of pulses per second). Today's personal computers operate at  clock speeds ranging from hundreds of megahertz to over several gigahertz.

Explanation

Surface Tension:

"The property of the surface of a liquid that allows it to resist an external force,

due to the cohesive nature of its molecules."

Explanation

Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity.

Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

Explanation

Kinetic energy is the energy an object has because of its motion.

Explanation

Explanation

• Silver bromide is useful in photography. whilst silver bromide is exposed to light it undergoes photochemical decomposition.
• The silver ions found in silver bromide are decreased to silver metallic which remains as an opaque photo at the photographic film.
• Silver bromide is a light sensitive salt and has been utilized in photography to coat a gel protected movie as silver halides which, after the film has been exposed are ‘evolved’ and render a poor photo of the precise scene fascinated by a digital camera.
