Answer:

4.3 x 10^16 kg

Explanation:

M = rv^2/G =[90,000 x 5.66^2] / [6.67 x 10^-11]

M = 43,226,446,776,611,694 = 4.3 x 10^16 kg - Ida's mass.

What changes in airplane longitudinal control must be made to maintain altitude while the airspeed is being decreased?
garik1379 [7]

Explanation:

The  changes can be made in airplane longitudinal control to maintain altitude while the airspeed is being decreased is

We can increase the angle of attack this would compensate for the decreasing lift. As the angle of attack directly controls the distribution of pressure on the wings. Moreover, increase in angle of attack will also cause the drag to increase.

The average distance from the sun to Pluto is approximately 6.10 × 109 km. How long does it take light from 
Scorpion4ik [409]
V= \frac{S}{t}
t= \frac{S}{V}<u />
t= \frac{S}{c}
t= \frac{6.1*10^{12}}{299792458}
t=20347.4098071s

It takes 20347.4098071s for light from the sun to reach Pluto.
The 6.1*10^9 is replaced by 6.1*10^12 on line 4 because we convert the distance from km to m. 
c = speed of light. If a different value was given in the previous question then use that instead of the value I used to do the final calculation.
