Sati [7]

Answer:

$m_2 = 23 kg$

Explanation:

As we know that the tension in two strings are

$T_2 = 111 N$

$T_4 = 222 N$

now we have

$F_{net} = ma$

so we can say

$(m_1 + m_2)a = T_2$

$(12 + m_2)a = 111$

also we have

$(m_1 + m_2 + m_3 + m_4) a = T_4$

$(12 + m_2 + 15 + 20) a = 222$

now divide two equations

$\frac{222}{111} = \frac{47 + m_2}{12 + m_2}$

$2m_2 + 24 = 47 + m_2$

$m_2 = 23 kg$

the candle had 350 J of energy in the chemical store. As it burned, 250 J was transferred by lighting to the surrounding

Elan Coil [88]

Answer:

Efficiency = 71%

Explanation:

Given the following data:

Output energy = 250 Joules

Input energy = 350 Joules

To find efficiency;

$Efficiency = \frac {Out-put \; energy}{In-put \; energy} * 100$

Substituting into the equation, we have;

$Efficiency = \frac {250}{350} * 100$

$Efficiency = 0.7143 * 100$

Efficiency = 71.43 ≈ 71%

Therefore, the efficiency of the candle is 71 percent.
