Answer:
False
Explanation:
An object's velocity can be described by it's direction. Because velocity is a vector. Besides velocity and acceleration are different units they can't be described by each other.
Answer:
Energy, 
Explanation:
It is required to find the energy of an electromagnetic wave with a frequency of 
. The energy of a wave in terms of its frequency is given by :
= frequency of em wave
So, the energy of an electromagnetic wave is 
Americium is a radioactive element .
- It goes through alpha decay during nuclear reactions .
The nuclear reaction.is given by
Here alpha can be written as He too
Answer is: this is an example of an Arrhenius acid.
An Arrhenius acid is a
substance that dissociates in water to form hydrogen ions or protons (H⁺).
For example hydrochloric acid: HCl(aq) → H⁺(aq) + Cl⁻(aq).
An Arrhenius base is a
substance that dissociates in water to form hydroxide ions (OH⁻<span>).
In this example lithium hydroxide is an Arrhenius base:</span>
LiOH(aq) → Li⁺(aq) + OH⁻(aq).
