What is the mass, in grams, of a pure iron cube that has a volume of 3.70cm cubed?
Arlecino [84]
To determine the amount in grams of the iron, we need data on the density of iron. From literature, it has a value of <span>p=7.9 g/cm3. We simply multiply the volume to the density. We do as follows:

mass = 3.70 (7.9) = 29.23 g Fe

Hope this answers the question. Have a nice day.</span>

Tamiku [17]
The correct answer is: 
<span>C) The actual frequency of the siren does not change despite appearances.

In fact, Bob will observe an increase in the apparent frequency as the emergency vehicle approaches him, while Jill will observe a decrease in the apparent frequency as the emergency vehicle moves away from him, because of the Doppler effect (the relative velocity between the observer and the source of the sound is changing), but this effect involves the apparent frequency, while the real frequency of the siren will remain the same.</span>

Sidana [21]

Answer:

a. Your mass with the basketball is 55.5 kg

b. Your new velocity is 0.045 m/s

Explanation:

We first add your weight and the basketballs weight to get 55.5 kg.

Then to find b. we use the equation: v final = (m1 * v1) / (m1 +m2)

So m1 is the basketball which is 0.5 kg and v1 is 5 m/s. So the top half is (0.5 * 5)

The bottom half is just our weights added together.
