Is the chorion the yolk of the egg
Umnica [9.8K]

Answer:

Yes

Explanation:

Inside the egg are a series of fluid-filled membranes that permit the embryo to survive: the amnion, allantois, yolk sac, and chorion. Around the chorion is the albumin or "white" of the egg, and an outer shell protects the whole egg, preventing drying while still permitting air to reach the embryo.

Which of these waves moves the fastest? <br> a. sound <br> b. radio <br> c. ocean <br> d. seismic
NARA [144]
First of all, the question is vague as you haven't mentioned the medium of propagation of the wave, which is extremely crucial.

For example light travels at <span>299,792</span> km/second in vacuum, but in certain semiconductors, it travels as slow as 9 km/second. Sound, ocean and seismic waves don't exist in vacuum at all.

If you mean the maximum possible speed any of these options can attain in any medium of choice for the different options, then the answer would be 
b. radio waves, which travel exactly at the speed of light in vacuum (299,792 km/second) and with an almost similar(slightly less) speed in air. (Radio waves are nothing but electromagnetic waves with low frequency)

A 15kg penguin slides on its belly down an icy, frictionless glacier. If the penguin started from rest and reaches a speed of 11
Schach [20]

Answer:

Mechanical Energy (initial) = Mechanical energy (final)

Ep(initial) + Ek(initial) = Ep(final) + Ek(final)

mgh(initial) + 1/2mv²(initial) = mgh(final) + 1/2mv²(final)

m being the mass of the penguin (kg)

g being gravitational acceleration (9.80 m/s²)

v(initial) being zero

h(final) being zero,i.e. final height is zero

v(final) being final velocity

solve for h(initial) being initial height at the top of the glacier

answer will be in metres

NB: don't forget to square the velocity

Explanation:

Since they mentioned frictionless, we know that this is a closed system therefore we are free to use this equation of conservation of mechanical energy
