D. Binary Stars

Well, galaxies are not stars at all rather they are collection of stars, nebulae, globular clusters and stuff like this.
Meteoroids are something entirely different.
Constellations are the pattern of stars.
So, "Binary Stars" is the Right One.

What is the size of the force acting on a copper wire with a magnetic flux density of 3.6 x 10-2 T acting at

anyanavicka [17]

Answer:

F = 0.414 N

Explanation:

Given that,

Magnetic flux density, $B=3.6\times 10^{-2}\ T$

The length of the wire, l = 24 m

Current, I = 0.48 A

We need to find the force acting on the wire. The formula for the force is given by:

$F=ILB$

Put all the values,

$F=0.48\times 24\times 3.6\times 10^{-2}\\\\F=0.414\ N$

So, the force acting on the copper wire is equal to 0.414 N.

Does the elf owl's small size allow it to live in cacti

kaheart [24]

Habitat
-In the Sonoran Desert region, elf owls are found mainly in riparian habitats (places where there is water), or in areas where saguaro cactus are plentiful.

Range
-Elf Owls are found from the southwest USA to Central Mexico and Baja California. Northern populations winter in Central Mexico and on the Pacific slope north to Sinaloa, Mexico.

Wild Status
-The most important threat to the elf owl is habitat loss both of its riparian forest habitat and desert-scrub habitats. In Arizona, the elf owl is not uncommon, but it's numbers are decreasing in California and Texas.

-So I mean like ya it's possible that they could live in cacti. Sorry that I couldn't give you a straight answer.

A tennis ball bounces on the floor three times. If each time it loses 11% of its energy due to heating, how high does it rise af

aalyn [17]

Answer:

h = 3.10 m

Explanation:

As we know that after each bounce it will lose its 11% of energy

So remaining energy after each bounce is 89%

so let say its initial energy is E

so after first bounce the energy is

$E_1 = 0.89 E$
