6. The temperature of an iron block decreases from 85°C to 25°C. If the mass for
the block is 1.2 kg, calculate the heat lost by the block. (Citon = 0.115 cal/g.°C)

8280 cal

Step-by-step explanation:

Q=mc(delta)T

Q=1200(0.115)(-60)

Q=8280 cal

I used 1200 g instead of 1.2 kg

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
