The true statements are

"Its temperature will rise until reaching 0°C."
And
"Its temperature will remain at 0°C until all the ice melts."

So, basically once the ice has reached 0°C we can conclude that the ice has probably fully melted. However the temperature has to stay there if we want the ice to melt.

We must remember that the melting point of ice is 0°C, and that Ice is completely melted at approximately 0°C so we must have those two statements true

You spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.111 liters per second and
Marrrta [24]

Answer:

29.5 m/s

Explanation:

Volumetric flowrate = (average velocity of flow) × (cross sectional area)

Volumetric flowrate = 0.111 liters/s = 0.000111 m³/s

Cross sectional Area of flow = πr²

Diameter = 0.00579 m,

Radius, r = d/2 = 0.002895 m

A = π(0.002895)² = 0.0000037629 m²

Velocity of flow = (volumetric flow rate)/(cross sectional Area of flow)

v = 0.000111/0.0000037629

v = 29.5 m/s

Approximately how many kelvins are equal to 60°f? <br> a. 333 <br> b. 323 <br> c. 413 <br> d. 289
Afina-wow [57]
D. 289
Take the formula:
K=5/9(Fahrenheit-32)+273
Plug in Fahrenheit
K=5/9 (60-32)+273
From here it is simple math and you can plug it into your calculator getting 288.5555556 and round to 289
