Answer:

(E) a greatly increased number of small particles in Earth’s orbit would result in a blanket of reflections that would make certain valuable telescope observations impossible

Explanation:

The trade is one strong reflection for many weak reflections (and more dangerous near-Earth space travel).

None of the answer choices except the last one has anything to do with the effect of exploding a satellite. When you are arguing that exploding a satellite is ill conceived, you need to address specifically the effects of exploding the satellite.

What is the horsepower of a 1,500 kg car that can go to the top of a 360 m high hill in exactly 1 min?

Airida [17]

Answer:

W = m g h work that must be done on car

P = W / t power that must be input (in Watts)

P = m g h / t = 1500 kg * 9.8 m/s^2 * 360 m / 60 sec

P = 88,200 watts

P = 88,200 watts / 746 watts / hp = 118 hp

What is the wavelength associated with 0.113kg ball traveling with velocity of 43 m/s?

maks197457 [2]

Answer:

Wavelength = 1.36 * 10^{-34} meters

Explanation:

Given the following data;

Mass = 0.113 kg

Velocity = 43 m/s

To find the wavelength, we would use the De Broglie's wave equation.

Mathematically, it is given by the formula;

$Wavelength = \frac {h}{mv}$

Where;

h represents Planck’s constant.

m represents the mass of the particle.

v represents the velocity of the particle.

We know that Planck’s constant = 6.6262 * 10^{-34} Js

Substituting into the formula, we have;

$Wavelength = \frac {6.6262 * 10^{-34}}{0.113*43}$

$Wavelength = \frac {6.6262 * 10^{-34}}{4.859}$

Wavelength = 1.36 * 10^{-34} meters

Suppose you were far from a planet that had a very strong gravitational field, and an emission line spectrum source on the surfa

dangina [55]

The answer would be it will be longer than the 656.3 nm. The reduced mass of positronium is less than hydrogen so the photon energy will be a reduced amount of for positronium than for hydrogen. So this will mean that the wavelength will be lengthier.
