Which description explains how inertia changes the effects of gravity on objects in the solar system?
natita [175]

The answer is; D

Inertia is the tendency of an object to resist change to its velocity and direction.  The bigger the mass of an object the higher its inertia. In space, the celestial bodies with a bigger mass have more inertia and have a higher gravitation pull (because they bend space-time more than smaller objects). The gravitational force of bigger objects influences on other celestial bodies and beats their inertia force by causing them to change direction and speed.

if you take a dried out white rose and place the stem in food coloring, will the rose turn the color you put the stem in
cricket20 [7]

Answer:

Yes, this is true. The reason is that the flower transpires and sucks the water in and distributes it as much as it can. You can also flip it upside down and hang it with petals down , allowing the liquid to enter the flower and then retaining color for longer periods of time and having more color.

Fe2O3 + 2A1 - Al2O3 + 2Fe
stepan [7]

I’m assuming in this scenario that 2.5 mols of Fe2O3 is reacting with excess reactant. Based on the balanced equation, you can see that there’s a 1:2 ratio between Fe2O3 and Fe. This means that to find the mols of Fe formed, you need to multiply the mols of Fe2O3 by 2.
2.50mol Fe2O3 * 2mol Fe/1 mol of Fe2O3 = 5.00mols Fe.

An airplane weighing 80,000. kg at takeoff reaches a speed of 880 km/h. What is the de Broglie wavelength in meters of the plane
Rzqust [24]

Answer:

3.39 * 10^-41 m

Explanation:

Given that:

speed of airplane = 880 km/hr

Mass of airplane = 80000 kg

Debroglie wavelength (λ) = h / mv

h = planck's constant = 6.626 * 10^-34

; mass = 80000kg

Velocity = 880km/hr to convert to m/s

Velocity = (880 * 1000m) / 3600 =244.44 m / s

λ = (6.626 * 10^-34) /(80000*244.44)

λ = (6.626 * 10^-34) / 19555200

λ = 3.3889 *10^-41

λ = 3.39 * 10^-41 m
