a 4.50 g coin of copper absorbed 54 calories of heat. what was the final temperature of the copper if the initial temperature wa

I am Lyosha [343]

The final temperature of copper is 155.43°C.

Step-by-step explanation:

The formula to apply is Q=m*Δt*c where ;

Q=heat energy, m=mass, c=specific heat capacity and Δt= change in temperature

Given that Q=54 calories , m=4.50 g and c=0.092 cal/g°C

In this question find Δt then ,the final temperature.

Δt=Q/m*c

Δt=54/4.50*0.092 =130.43°C

To find final temperature, apply the formula;

Δt=Final temperature - Initial temperature

130.43°C=Final temperature-25°C

130.43°C+25°C=Final temperature

155.43°C

ii. A machine is sold for 7,000/-. The gross loss is 20% of the cost. What are the cost and gross loss?

aleksley [76]

Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

$x-20\%\text{ of }x=7000$

$x-\dfrac{20}{100}x=7000$

$x-0.2x=7000$

$0.8x=7000$

Divide both sides by 0.8.

$x=\dfrac{7000}{0.8}$

$x=8750$

So, the cost of the machine is 8750/-.

Now,

$\text{Gross Loss}=\text{Cost}-\text{Selling price}$

$\text{Gross Loss}=8750-7000$

$\text{Gross Loss}=1750$

Therefore, the gross loss is 1750/-.

Garne Problem med

Citrus2011 [14]

Total distance the rover need to travel is $D = 1miles$ .

<u>Step-by-step explanation:</u>

We have , Garne Problem med . A rover needs to travel mile to reach its destination traveled mile. a rover needs to travel 5/8 mile to reach its destination it has already travel 3/8 miles . We need to find that how much farther does the rover need to travel , Let's do it step by step:

First , rover has already traveled 3/8 miles , Let total distance to be traveled by rover is D :

⇒ $D = \frac{3}{8} + d$ , where d is distance left to cover .

Now, rover need to travel 5/8 miles more to reach destination :

⇒ $D = \frac{3}{8} + d$ , where d is distance left to cover , So $d = \frac{5}{8}$

⇒ $D = \frac{3}{8} + d$

⇒ $D = \frac{3}{8} + \frac{5}{8}$

⇒ $D = \frac{3+5}{8}$

⇒ $D = \frac{8}{8}$

⇒ $D = 1miles$

∴ Total distance the rover need to travel is $D = 1miles$ .
