I just got it correct on Edg
Answer:
Explanation:
distance of shuttle from centre of the earth = radius of the orbit
= 6300 + 300 = 6600 km
= 6600 x 10³
Formula of time period of the satellite
T = 2π R /v₀ , v₀ is orbital velocity
v₀ = √gR , ( if height is small with respect to radius )
T = 2π R /√gR
= 2π√ R /√g
= 2 x 3.14 x √ 6600 x 10³ / √9.8
= 2 x 3.14 x 256.9 x 10 / 3.13
= 5154.41 s
= 5154.41 / 60 minutes
= 85.91 m
85.9 minutes.
2 ) No of sunrise per day = no of rotation per day
= 24 x 60 / 85.9
= 16.76
or 17 sunrises.
It increases
Explanation:
A circuit's resistance increases as more resistors are added to it in series.
Series connection of circuit provides an additive increase in the resistance offered by the overall circuit.
A resistor is a device in a circuit that impedes the flow of electric current. It simply uses electric current.
Examples are bulbs, radio, television.
The more of these devices connected one to another in series, the more the resistance increases.

Fluorine (F) has higher potential energy as Neon (N) is a noble/inert gas.
Fluorine will lose another electron to gain stability.
Answer:
Therefore, highest point that the cannon ball reaches is 168.7m
Explanation:
the cannon is fired at an angle 30 o to the horizonatal with a speed of 155 m/s
highest point that the cannon ball reaches?
g = 9.8m/s2
Therefore, highest point that the cannon ball reaches is 168.7m
