The surface temperature on venus may approach 737 k. what is this temperature in degrees celsius? the temperature on mercury may drop to –265 °f at night. what is this temperature in degrees celsius?

Temperature in Venus = 464°C

Temperature on Mercury = -165°C

Explanation:

The relation between Kelvin and Celsius degrees is 0°C = 273.15 K, hence to convert the temperature tu Celsius we need to subtract 273.15:

737 - 273.15 = 463.85°C

That is 464°C with correct significant figures.

The relation between Fahrenheit and Celsius is:

Temperature in Celsius = (temperature in Fahrenheit - 32) x 5/9

(-265°F - 32) x 5/9 = -165°C

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
