Answer:
A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.
Answer:
Speed is a "scalar" quantity
(C) is the correct answer
An object could travel at 10 m/s to some point and then return to the origin at 10 m/s for an average speed of 10 m/s, however it's displacement over that time would be zero for a net velocity of zero.
Answer and Explanation:
The answer is <u>D) Alpha and Gamma</u>
Gamma radiation does not cause transmutations.
A <u>transmutation</u> is the <u>conversion of an atom of one element to an atom of another. This generally occurs through nuclear reacting.</u>
There are three main types of radiation: alpha, beta, and gamma. Both beta and alpha decay cause changes to the mass and atomic numbers. This results in a transmutation. Gamma radiation, however, does not.
Gamma radiation is the result of a gamma ray. In essence, the nucleus emits a high-energy proton. This is very penetrating and can only be stopped by aluminum, lead, soil, water, and concrete. This type of radiation does not change the element and, therefore, does not cause a transmutation.

Answer:
Increasing its surface area
Explanation:
In Science, increasing the surface area of a gas increases its collision rate and is one evolutionary strategy that has maximized gas diffusion by catalysing the rate of gaseous reaction.
Explanation:
In order from highest to lowest energies the parts of electromagnetic spectrum are named as
Gamma rays,
X-rays,
ultraviolet radiation,
visible light,
infrared radiation,
and radio waves.
Microwaves are a subsections of radio waves. They are used in microwave ovens to heat the food items.
This is expected EM spectrum in field of science.
