Answer:

a. endothermic

Explanation:

The reaction shown is an endothermic reaction. In such reaction, they require an input of energy.

Endothermic changes involves absorption of heat from the surrounding.
The surrounding becomes colder at the end of the reaction.
When heat is on the reactant side, it suggests a reaction that requires a considerable input of energy.

A car has two horns, one emitting a frequency of 199 hz and the other emitting a frequency of 203 hz. what beat frequency do the

andriy [413]

Beat frequency, fb = |f2-f1|

That is, beat frequency is the absolute difference between two frequencies. Is is as a results of destructive and constructive inferences.

Therefore, in this case:

fb = 203 - 199 = 4 Hz

If a cart of 2 kg mass has a force of 8 newtons exerted on it, what is its acceleration?

Ilia_Sergeevich [38]

Force = mass * acceleration

F = ma

8 N = 2 kg * a

8 = 2a

2a = 8

a = 8/2 = 4

acceleration = 4 m/s²

Two cubes, one silver and one iron, have the same mass and temperature. A quantity Q of heat is removed from each cube. Which on

scoundrel [369]

Answer:

C) specific heat capacity

Explanation:

As we know that heat given to the system to change the temperature is given as

$Q = ms \Delta T$

here we know that

Q = thermal energy given to the system

s = specific heat capacity of the system

$\Delta T$ = change in temperature

so here we know that

$\Delta T = \frac{Q}{ms}$

here we know that heat given to the two cubes is of same amount as well as the mass is same but the final temperature is different because of the specific heat capacity (s)

So correct answer would be

C) specific heat capacity
