Darwin observed fossils of glyptodonts, which are now extinct. Living armadillos are the only animals remaining on Earth that ar

e similar to glyptodonts. Armadillos live in the same places that glyptodonts lived.
What did Darwin most likely conclude about the two types of animals?

Glyptodonts were better adapted to the environment.
Glyptodonts outcompeted armadillos for food.
Glyptodonts were early relatives of armadillos.
Glyptodonts had the exact same adaptations as armadillos.

Answer:

C Glyptodons were early relatives of armadillos.

Explanation:

Darwin would have come to this conclusion because glyptodons over time became armadillos, which you can tell by evolution that they were better evolved to survive than glyptodons. Due to this, they outlived the glyptodons.

A cynical block on an air table vibrates horizontally in SHM with an amplitude of 8.0cm and a frequency of 1.50Hz. If a smaller
AveGali [126]

Answer:

μ = 0.724

Explanation:

maximum acceleration for SHM

a = ω²A

ω = 2πf

a = 4π²f²A

a = 4π²(1.50)²(0.080) = 7.106... m/s²

μ = F/N = ma/mg = a/g = 7.106/9.81 = 0.7243...

I'm cynical that a block can be cynical. Wassa madder, doesn't trust anyone?

Compare the characteristics of 4d orbitals and 3d orbitals and compared the following sentences. Check all that apply
charle [14.2K]

Answer :

<em>(b) 4d orbitals would be larger in size than 3d orbitals</em>

<em>(e) 4d orbitals would have more nodes than 3d orbitals</em>

Explanation :

As we move away from one orbital to another, the distance between nucleus and orbital increases. So, 4d orbitals would be far to the nucleus than 3d orbitals.

Hence, 4d orbitals would be larger in size than 3d orbitals.

Number of nodes is any orbital is n - 1 where, n is principal quantum number.

So, number of orbital in 4d is 3.

And number of orbital in 3d is 2.

So, options (b) and (e) are correct.

Carlotta does 2000 j of work on a machine. The machine does 500 J of work what is the efficiency of this machine
almond37 [142]

Efficiency of a machine = (useful output energy) / (total input energy)

Efficiency = (500 J output work) / (Carlotta's  2,000 J input work)

Efficiency = (500 J) / (2,000 J)

Efficiency = 0.25

<em>Efficiency = 25%</em>

A centrifuge in a medical laboratory rotates at an angular speed of 3500 rev/min. When switched off, it rotates 46.0 times befor
BlackZzzverrR [31]

Answer:

The angular acceleration of the centrifuge is -231.74 rad/s².

Explanation:

Given that,

Angular speed = 3500 rev/min = 366 rad/s

We need to calculate the angular displacement

Using formula of angular displacement

\theta=2\pi n

Put the value into the formula

\theta=2\pi\times46

\theta=289.02\ rad

We need to calculate the angular acceleration

Using equation of motion

\omega_{f}^2=\omega_{i}^2+2\alpha\theta

\alpha=\dfrac{\omega_{f}^2-\omega_{i}^2}{2\theta}

\alpha=\dfrac{0-(366)^2}{2\times289.02}

\alpha=-231.74\ rad/s^2

Hence, The angular acceleration of the centrifuge is -231.74 rad/s².
