the distance of a planet from its sun is 19000000 miles. if there are 29400000 seconds in one orbit, find the speed of the plane

lisabon 2012 [21]

Orbit circumference
= 2 pi *1.9*10^7 miles 

time for orbit trip = 2.9*10^7 s 

speed = 2 pi *1.9 / 2.9 miles/second 

= 4.12 miles/second 

You did not say what units 
in miles per hour, multiply by 3600 and get 
14,820 miles/hour

Which statements are true for two oppositely charged, isolated parallel plates: C=capacitance, U=stored energy (Q and -Q = charg

vlada-n [284]

Answer:

Explanation:

1) True. The stored energy (U) is proportional to the electric field strength (E). The electric field strength decreases when a dielectric is introduced hence inserting a dielectric decreases U.

2) False. From the formula $C=\frac{Q}{V}=\frac{Q}{Vd}$ , capacitance is inversely proportional to distance hence if the distance is doubled, capacitance decreases.

3) False. As the distance between the electric field and the object increases, its electric field decreases.

4) False. If a dielectric is inserted, the plates are further separated. Q stays the same.

5) True. The electric field strength decreases when a dielectric is introduced and capacitance is inversely proportional to electric field hence Inserting a dielectric increases C

6) True. If a dielectric is inserted, the plates are further separated. Q stays the same.

7) True. When the distance is doubled, U increases
