Is a butterfly asymmetry or Bilateral Symmetry?

2 answers:

7 0

Animals with bilateral symmetry have one line that divides them into two mirror images. For example: a butterfly. If you drew a line exactly down the center of its body from its head to its tail, the two halves would be the same, but mirror images of each other.

Hope this helps ;)

Most of the time, butterflies have bilateral symmetry. This means that there is one line of symmetry. Since butterflies are the same to the left as to the right, this is true.

Hope this helps!

A car is traveling at a speed of 38.0 m/s on an interstate highway where the speed limit is 75.0 mi/h. Is the driver exceeding t

lidiya [134]

Answer:

Yes, the car driver is exceeding the given limit.

Explanation:

<u>Given:</u>

Speed of the car, v = 38.0 m/s.
Speed limit of the highway, $\rm v_o=75.0\ mi/h.$

<h2><u>Converting the speed limit from mi/h to m/s:</u></h2>

We know,

1 mi = 1.60934 km.

1 km = 1000 m.

Therefore, 1 mi = 1.60934 × 1000 m = 1609.34 m.

1 hour = 60 minutes.

1 minute = 60 seconds.

Therefore, 1 hour = 60 × 60 seconds = 3600 seconds.

Using these values,

$\rm 1\ \dfrac{mi}{h}=\dfrac{1609.34\ m}{3600\ s}=0.447\ m/s.$

Therefore,

$\rm v_o = 75.0\ mi/h=75.0\times 0.447=33.52\ m/s.$

Clearly,

$\rm v_o$

which means, the car driver is exceeding the given speed limit.

11.76 cm² into two significant figures and include the appropriate units

PilotLPTM [1.2K]

You will need to turn this into scientific notation, so:

1.176 × 10^1 cm^2

To two significant figures means to two digits so since 7 is greater than 5, you will need to round up.

Final answer is:

1.2×10^1 cm^2

Dmitry [639]

Answer:

The ratio of their orbital speeds are 5:4.

Explanation:

Given that,

Mass of A = 5 m

Mass of B = 7 m

Radius of A = 4 r

Radius of B = 7 r
