Answer:five times five is twenty five divded by 10 is 2.5 seconds of acceleration
You take 75 and divide is by 1.5 and you’ll get c 50 km/hr
The southern hemisphere would be having winter
How much a substance increase its temperature due to heat transfer depends on its specific heat.
The specific heat is the amount of heat required to increase the temperature of one mass of substance in 1 °Celsius.
The lower the specific heat the more the substance change its temperature with a given amount of heat, the greater the specific heat of the substance the lesser the change of temperature with the same amount of heat.
Then, to predict which of the two blocks will have the greater rise you need to compare the specific heats of the metals.
From tables, the specific heat of gold is 0.129 J/g°C and specific heat of iron is 0.450J/g*°C.
Then, gold will raise more its temperature than iron, after the addition of the same amount of heat.
We use about 38 percent of Earth's land surface for agriculture
