Answer:
Explanation:
the equation you use here is m=fa or mass=force x acceleration
you plug in the 13.5 N as the force, 6.5 m/s^2 as the acceleration, and do the math.
13.5 x 6.5
That would equal 87.75 which would be your answer.
The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
(1)
Where:
- Final temperature, in degrees Celsius.
- Initial temperature, in degrees Celsius.
- Time, in minutes.
- Cooling rate, in
.
- Current temperature, in degrees Celsius.
Please notice that substance reaches thermal equilibrium when
, that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that
,
,
and
, then the cooling rate of the substance is:





The cooling rate of the substance is approximately 0.0732.

Explanation:
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction. The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series
The details in the passage that depicts an atmosphere of desolation are:
- <em>"but the towers themselves look blind"</em>
- <em>"shattered image of a man or a god"</em>
