A titanium bicycle frame displaces 0.314 l of water and has a mass of 1.41 kg. what is the density of the titanium in g>cm3 ?
Kobotan [32]
The density of an object is the ratio of its mass over the volume. This translates to the amount of substance present in a certain space and can mathematically be expressed as,
 
                   density = mass / volume

In this item, we are given that the object of mass 1.41 kg is able to displace 0.314 L of liquid. The volume of water displaced is also the volume of the object. Hence,
                  density = 1.41 kg / 0.314 L = 4.49 kg/L

Then, we convert the calculated volume of g/mL.
                  density = (4.49 kg/L)(1 L / 1000 mL)(1000 g/1 kg)
                   <em>   density = 4.49 g/mL</em>

I need some help w/ this:
pochemuha

Answer:

The velocity of the police car is, v = 17.798 m/s

Explanation:

Given data,

The actual frequency of the siren, f = 2010 Hz

The observed frequency of siren is, f' = 2120 Hz

The velocity of the observer, v' = 0 m/s

The velocity of the source, v = ?

The formula for Doppler effect,

                            f'=\frac{(V+v')}{(V-v)}f

Where,

                         V - velocity of sound waves in air.

                          v=V-(V+v')\frac{f}{f'}

Substituting the given values,

                         v=343-(343+0)\frac{2010}{2120}

                                 v = 17.798 m/s

Hence, the velocity of the police car is, v = 17.798 m/s

Asap. I need an explanaton to how this works as well
bazaltina [42]

Answer:

B: Electrical - Heat

C: Electrical - kinetic

Explanation:

When the hair dryer is plugged to electric supply, electrical energy is converted into heat. When this electricity is circulated through a resistor, heat is now created in the form of losses which make the air around the resistors to be heated.

After that process, this electricity turns into kinetic energy because it forms Electric energy which moves the fan in order to create a flow with the air that's heated.
