Answer:

a generator that allows them to convert kinetic energy into potential energy

Explanation:

Rescue workers can accomplish this by using a generator that allows them to convert kinetic energy into potential energy. Such as a crank generator, with these, they spin a crank with their hands and the generator takes that kinetic energy that is building up through the work that the rescuer is exerting and converts it to potential electric energy that can properly be used to provide energy to the batteries for their equipment. This is what is generally used for situations such as what rescuers go through when there is no electricity around.

If an object has a Mass of 11g and a volume fo 13mil, what is its density?
Nimfa-mama [501]

Answer:

\boxed {\boxed {\sf B. \ d \approx 0.85 \ g/mL}}

Explanation:

Density is found by dividing the mass by the volume.

d=\frac{m}{v}

The mass of the object is 11 grams and the volume is 13 milliliters.

m= 11 \ g \\v= 13 \ mL

Substitute the values into the formula.

d= \frac{11 \ g}{13 \ mL}

Divide.

d=0.846153846 \ g/mL

Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 4 to a 5.

d \approx 0.85 \ g/mL

The density is about <u>0.85 grams per milliliter.</u>
