Seawater found to be seeping up through the canyon floor is why
scientists think Grand Canyon was once covered by an ocean.
Grand cayon is located in Arizona, United States and comprises of a lot of
fossil records and rocks which makes it one of the best sites for geological
study.
The Grand cayon was found to be seeping through its floor which made
scientists think it was once covered by an ocean years ago.

Answer:
The answer to your question is: density = 0.993 g/ml
Explanation:
Data
mass beaker empty = 29.3 g
volume of liquid = 15 ml
mass beaker + liquid = 44.2 g
Formula
density = mass / volume
Process
mass of liquid = 44.2 - 29.3
= 14.9 g
density = 14.9 / 15
= 0.993 g/ml
Answer:
TRUE: <span>Forces that act between two molecules are referred to as Intermolecular Forces.
Explanation:
Those forces which are present within the molecule among atoms are called as Intramolecular Forces, while, The forces which are present between two molecules are called as Intermolecular Forces. Intermolecular Forces are as follow,
1) Hydrogen Bond Interactions
2) Dipole-Dipole Interactions
3) London Dispersion Forces</span>

Hi!
<u>The correct options would be: </u>
is an electron
is emitted from nucleus
has a -1 charge
Explanation:
A beta particle is a result of a neutron (a neutral particle) changing into two particles of opposite charges - a high energy electron (with a negative charge -1) and a positron (with a positive charge +1). Neutrons are present in the nucleus of an atom, and thus the beta particles are said to be emitted from the nucleus. They do have a charge, not zero, but it is not +2 and can only be either -1 or +1. This form of radiation is not electromagnetic energy because beta particles are massless, and do not travel at the speed of light (both being characteristics of electromagnetic radiation). Beta particles are not pure forms of energy.
Hope this helps.
