A bear can run up to 18.47 feet per second. How many feet could the bear run in 3.9 seconds? 720.33 feet 7,203.3 feet 72.033 fee
JulsSmile [24]

Answer:

72.033 ft

Step-by-step explanation:

To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.

\frac{18.47}{1}=\frac{y}{3.9}

Step 1: Switch sides

\frac{y}{3.9}=\frac{18.47}{1}

Step 2: Apply rule: \frac{a}{1}=a

\frac{y}{3.9}=18.47

Step 3: Multiply both sides by 3.9

\frac{3.9y}{3.9}=18.47\cdot \:3.9

Step 4: Simplify

y=72.033

The bear can run 72.033 feet in 3.9 seconds

Define the first law of thermodynamic with one example.
DanielleElmas [232]

Answer:

See explanation below.

Step-by-step explanation:

The first law of thermodynamic states that heat is a form of energy, and as such, is subject to the principle of conservation of energy (Energy is not destroyed or created but remains constant)

For example, when you put an ice cube in water, the ice will melt but the water will get colder, this is because the temperature between the ice cube and the water tends to an equilibrium and the total heat in the system remained the same during this time.
