A)
Obw= 2*3,14*2 =12,56cm
Obw = 6,28*4 = 25,12m
Obw = 6,28*0,3 = 1,884cm
Obw = 6,28*10 = 62,8km

b)
Obw = 6,28*1 = 6,28cm
Obw = 6,28 * 1,5 = 9,42m
Obw = 6,28 *0,2 = 1,256cm
Obw = 6,28 *100 = 628m

c)
6,28*r = 10m
r≈1,59m

6,28*r = 1m
r≈0,159

6,28*r = 628mm
r=100mm

6,28*r = 3,5cm
r≈ 0,557cm

identify and list some examples of ways that could create a positive digital footprint work put it in a paragraph

Hoochie [10]

Answer:

Explanation

Be active on social media. Now I don't mean to be addicted to it, like alot of people are. Instead, just put yourself out there. Be friendly and social, and remember think before you post. This is because your things you post and do online are permantely stored, even if you delete it. Many job employers and schools look and do a quick look up of you online, just to check your background and see if you are fit. Also to keep a positive digital footprint, try to delete and deactivate accounts online, ex. social platform, blogs, because then it won't be searchable online.

On Earth, the Sun appears to move 15˝/hr across the sky.

ladessa [460]

Answer:

speed of apparent on moon = 0.50847° per Hour

speed of apparent movement on Jupiter= 36.36° per Hour

Explanation:

given data

Sun appears to move = 15˝/hr

to find out

How many degrees per hour would the Sun appear to move if we at equator of the Moon and How many degrees per hour would the Sun appear to move if we at the equator on Jupiter

solution

we know that sun is stable it not move but earth is revolving around that sun but it appear sun rise

so movement of sun in sky 360° every day

and time taken = 24 hours

so as we have given

speed of the apparent movement= $\frac{360}{24}$ °/Hour = 15 °/Hour

we have given Time taken by the sun to Moon's sky = 29.5 days = 29.5 × 24 = 708 hours

speed of apparent on moon = $\frac{360}{708}$

speed of apparent on moon = 0.50847° per Hour

and

we know Time taken by the sun to Jupiter = 9.9 hr

speed of apparent movement on Jupiter= $\frac{360}{9.9}$

speed of apparent movement on Jupiter= 36.36° per Hour
