How do the discovery of gravity and the invention of electronic satellites most likely relate to the processes of scientific inv

estigation and technological design?
A) Engineers used the process of technological design to discover how gravity holds matter in orbit, and then scientists investigated satellites in nature.
B) Scientific investigations discovered that gravity holds objects in orbit, and then technological designers used the discovery to develop electronic satellites.
C) Since scientists were curious about gravity, they used the process of scientific investigation to build the first object that would orbit Earth.
D) Technological designers invented the electronic satellite, and then scientific investigators conducted research to learn how and why it orbited around Earth.

Why does a skateboard coasting on a flat surface slow down and eventually comes to a stop
Maurinko [17]

It depends on what skateboard. It will stop mainly because some  skateboards need a hill or curvy platform to function.

hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.1 m/s , a typical raindrop speed. How fast i
Y_Kistochka [10]

Answer:

7.92 m/s

Explanation:

m_1 = Mass of raindrop = 45m_2

m_2 = Mass of mosquito

u_1 = Initial Velocity of raindrop = 8.1 m/s

u_2 = Initial Velocity of mosquito = 0 m/s

v = Velocity of center of mass

For elastic collision

m_1u_1 + m_2u_2 =(m_1 + m_2)v\\\Rightarrow v=\frac{m_1u_1 + m_2u_2}{m_1 + m_2}\\\Rightarrow v=\frac{45m_2\times 8.1 + m_2\times 0}{45m_2 + m_2}\\\Rightarrow v=\frac{364.5m_2}{46m_2}\\\Rightarrow v=7.92\ m/s

Hence, the velocity of the attached mosquito, falling immediately afterward is 7.92 m/s

Wave length of sodium light is 5893A express in nanometre​
DaniilM [7]

Answer:

589.3 nm

Explanation:

The wavelength of a sodium light is 5893 A.

We need to find the wavelength in nm.

5893\ A=5893\times 10^{-10}\ m

Also, 1\ nm=10^{-9}\ m

5893\ A=5893\times 10^{-9}\times 10^{-1}\ m\\\\=5893\times 10^{-1}\ nm\\\\=589.3\ nm

So, the wavelength of sodium light is 589.3 nm.

If If the mass of a material is 88 grams and the volume of the material is 24 cm3, what would the density of the material be?
Tanzania [10]

Answer:Mass is measured on a triple beam balance units = GRAMS.

Volume is measured in two ways.

Regular Object = Length X Width X Height units = cm3

Irregular Objects units = mL

 Pour about 50 mL of water into a graduated cylinder. Measure and record the exact amount.

 Add the object. Measure and record the new water level.

 SUBTRACT the original water amount from the new water level to find the volume of the object.

= MASS (g)

VOLUME (cm3

)

Example One:

A mineral has a mass of 100g and a volume of 10 mL. What is its density?

= mass = 100g = 10 g/mL

Volume 10 mL

Example Two:

A mineral has a mass of 25 g and a volume of 5 cm3

. What is its density?

= mass = 25g = 5 g/cm3

Volume 5 cm3

**Mass ÷ Volume to find the numerical answer. Bring over BOTH units**
