Answer:

C)No

Explanation:

When moving oxidation numbers down as subscripts in an ionic bond, you do not include the charge either positive or negative.

The process of moving oxidation number down as subscript is known as exchange of valency.

The combining power is used in exchanging valency and this is oxidation number exchanged. The number corresponds to the number of electrons usually lost or gained or shared by atoms of elements during chemical combination or the number of positive or negative charges carried by ions.

The combining power is exchanged as simple whole number ratio during the formation of chemical formulae of compounds.

A 1.5-kilogram cart initially moves at 2.0 meters per second. It is brought to rest by a constant net force in 0.30 second. What

AnnZ [28]

Acceleration = (change in speed) / (time for the change)

Change in speed = (speed at the end) minus (speed at the beginning.

The cart's acceleration is

 (0 - 2 m/s) / (0.3 sec)

 = ( -2 / 0.3 ) (m/s²) = -(6 and 2/3) m/s² .

Newton's second law of motion says

 Force = (mass) x (acceleration) .

For this cart: Force = (1.5 kg) x ( - 6-2/3 m/s²)

 = ( - 1.5 x 20/3 ) (kg-m/s²)

 = - 10 newtons .

The force is negative because it acts opposite to the direction 
in which the cart is moving, it causes a negative acceleration, 
and it eventually stops the cart.

givi [52]

Answer:

Acceleration due to gravity, $a=4.61\times 10^{-14}\ m/s^2$

Explanation:

It is given that,

Mass of Pluto, $m=1.4\times 10^{22}\ kg$

Distance between Neptune and Pluto, $r=4.5\times 10^{12}\ m$

The force of gravity is balanced by the gravitational force between Neptune and Pluto. It is given by :

$a=\dfrac{Gm}{r^2}$

$a=\dfrac{6.67\times 10^{-11}\times 1.4\times 10^{22}}{(4.5\times 10^{12})^2}$

$a=4.61\times 10^{-14}\ m/s^2$

So, the acceleration due to gravity at Neptune due to Pluto is $4.61\times 10^{-14}\ m/s^2$ . Hence, this is the required solution.

Who conducted the study?

Explanation:

One good question to ask the toothpaste making company is who conducted the study?

A company making toothpaste claiming a scientific study revealed that their toothpaste makes the mouth five times cleaner must have introduced a bias in this finding.

For a scientific study to be accepted and substantiated, it must have been tested and repeated by other scientists.
If no other scientist confirms this, then there is an obvious bias in the claim and it is not scientific.
