Jenny and Betty are having a great time at Busch Gardens riding the Ubanga Banga bumper cars. Jenny, who is traveling southward

in her bumper car, aims her car toward Betty, who is traveling northward in her bumper car. The cars collide and briefly come to a stop. What can you say about the magnitude of the force that Jenny's car exerts on Betty's car versus the magnitude of the force that Betty's car exerts on Jenny's car?

The temperature of 1 m^3 of water is decreased by 10°C. If this thermal energy is used to lift the water vertically against grav
Rama09 [41]

Answer:

h = 4271.43 m

Explanation:

given,

Volume of the water = 1 m³

temperature decrease by = 10°C

heat removed from water

Q = m c ΔT                            

Q = ρ V c ΔT                            

   = 1000 × 1 × 4186 × 10

   = 4.186 × 10⁷ J

energy is used to do work to move the water against its weight

Q = force  × displacement

4.186 × 10⁷ J =  m g × h                    

4.186 × 10⁷ J =  1000 × 1 × 9.8 × h                

h = 4271.43 m                                

hence, the change in height of is equal to h = 4271.43 m

Will convection always work faster and more efficiently than conduction?
Stells [14]

Answer:

Yes convection will always work faster and more efficiently.

Explanation:

When a gas or a liquid is heated, hot areas of the material flow and mix with the cool areas. ... Convection transfers heat over a distance faster than conduction. But ultimately conduction must transfer the heat from the gas to the other object, though molecular contact.

What is the wavelength of a wave with a frequency of 466 Hz and a speed of
Volgvan

Answer:

<h3>The answer is option B</h3>

Explanation:

The wavelength of a wave can be found by using the formula

\lambda =  \frac{c}{f} \\

where

c is the speed of the wave

f is the frequency

From the question

c = 343 m/s

f = 466 Hz

We have

\lambda =  \frac{343}{466} \\  =  0.73605150...

We have the final answer as

<h3>0.74 m</h3>

Hope this helps you
