Physics
1 answer:
Semmy [17]3 years ago
3 0

Answer: Option (B)

Explanation:

Gas giants are the outer planets that are dominantly comprised of hydrogen and helium. They are Jupiter and Saturn, Whereas ice giants are the outer planets that are composed of mostly ice and ammonia and methane also is present. They are Uranus and Neptune. Both these giant planets are bigger in size in comparison to earth.

The ice giants are far away from the sun, so its very cold and there is abundant ice in the planet.

The <u>main differences between gas giants and ice giants is that, there is the presence of a thick layer of liquid metallic hydrogen in interior part of the gas giants</u>.

The gas giants contains approximately 90% of hydrogen, so when one travels through the interior of this planets, it can be observed that the atmospheric pressure is so extreme that it converts all of its gas into a very highly dense liquid.

Thus, the correct answer is option (B).

A person Drove from 8am Tuesday to 5pm Wednesday. Total drive 396 miles. He have lunch for 30 min on Tuesday and sleep overnight
r-ruslan [8.4K]

Answer:

average speed = 18 miles / hour

Explanation:

Given data

drive = 396 miles

time = 8 am Tuesday to 5 pm Wednesday = 33 hours

lunch = 30 min Tuesday  + 30 min Wednesday = 60 min = 1 hour

sleep = 7 pm Tuesday to  5 am Wednesday = 10 hours

to find out

average speed

solution

we know that he take total time = 33 hours and he took rest + luch = ( 1 + 10 hours)

so total travel time is = 33 - 11 = 22 hours

so

average speed = distance / time

average speed = 396 / 22

average speed = 18 miles / hour

arsen [322]

Answer:

  • 64.93 rad/s
  • 38.956 km

Explanation:

(a)

  \dfrac{6.2\cdot 10^2\,\text{rev}}{60\,\text{s}}\times\dfrac{2\pi\,\text{rad}}{\text{rev}}=\dfrac{62\pi\,\text{rad}}{3\,\text{s}}\approx\boxed{64.93\,\text{rad/s}}

__

(b)

  d=r\theta=(3.0\,\text{m})(2.0\cdot 10^2\,\text{s})\left(\dfrac{62\pi\,\text{rad}}{3\,\text{s}}\right)=124\pi\cdot 10^2\,\text{m}=\boxed{38\,956\,\text{m}}

The distance between two successive maximaof
denpristay [2]

Answer:

v = 1.224 m/s

Explanation:

given,                          

distance between the two successive maxima = 1.70 m

number of crest = 8          

time = 11 s                            

frequency is equal to number of cycle per secod

f = \dfrac{8}{11}          

f = 0.72\ Hz                

velocity of wave

v = f x λ                

v = 0.72 x 1.70        

v = 1.224 m/s          

Hence, the wave speed is equal to v = 1.224 m/s
