The heating of Venus led to a further release of ______ from its surface. With nowhere for the greenhouse gas to go, Venus ended

DiKsa [7]

Answer:

The answer would be B

Explanation:

The atmosphere of Venus traps in lots of what from the Sun, it is the hottest planet in our solar system because of this. CO2 is a greenhouse gas and traps in heat. So B would be your answer.

A large goose lands in a lake and bobs up and down for a short time. A fisherman notices that the first wave crest created by th

sleet_krkn [62]

Answer:

11.85m

Explanation:

For the development of this problem we must resort to the concepts of the basic kinematic equations that define the distance of a body, such as speed for a certain time, that is,

$D=v*t$

From the information provided we say that the distance between the cretas is 0.6m,

$D_{crest} = 0.6m$

In our information we have also that the length between the first and latest wave is in time terms of 2.2s. They are 4 waves in 3 intervals then

$D_{T} = D_{crest}*3= 0.6*4 = 2.4m$

$t=1.6s$

$\upsilon = \frac{D_{T}}{t} = \frac{2.4}{1.6}$

$\upsilon = 1.5 m/s$

Then the distance from the shore is given by the speed of the waves for the total time. That is

$X = \upsilon*T\’$

$X = 1.5*7.9$

$X= 11.85m$

How does air resistance affect the acceleration of falling objects?

BlackZzzverrR [31]

Air resistance opposes the motion of falling objects. Dense air prefers to stay at low heights. More dense the air is, more air resistance it produces. Hence acceleration of falling objects decreases. Hope this helps!

Which of The following has the most kinetic energy a 25-kg fish tank sitting on a table, A 50-kg Fish swimming in a fish tank, A

suter [353]

Well, kinetic energy is energy of motion, and three of these
four objects are just sitting there and not moving at all.

The tank, the car, and the boulder have no kinetic energy at all,
since they're not moving.

The fish who is swimming is the only one with any kinetic energy,
so we don't even have to calculate how much. The fish is your man.

An airplane traveling at one third the speed of sound (i.e., 114 m/s) emits a sound of frequency 3.72 kHz. At what frequency doe

nlexa [21]

Answer:

f'=5.58kHz

Explanation:

This is an example of the Doppler effect, the formula is:

$f'=\frac{(v+v_o)}{(v+v_s)}f$

Where f is the actual frequency, $f'$ is the observed frequency, $v$ is the velocity of the sound waves, $v_o$ the velocity of the observer (which is negative if the observer is moving away from the source) and $v_s$ the velocity of the source (which is negative if is moving towards the observer). For this problem:

$f=3.72kHz\\v=342m/s\\v_o=0m/s\\v_s=-114m/s$

$f'=\frac{(342+0)}{(342-114)}3.72\times10^3\\f'=\frac{342}{228}3.72\times10^3\\f'=(1.5)3.72\times10^3\\f'=5580Hz=5.58kHz$
