Answer:

Well the definition of an application is the act of putting to a special use or purpose so lam assuming that you want specific uses that scientists make of gravity in their work.

Well our first application has helped us to send satellites around the solar system with what Nasa calls gravity assist. Using a particular planets gravity to slingshot a satellite to another destination. Look it up.

The next application much simpler but here on Earth. There are many hydro-electric power stations in use all over the world. Water is stored at a high level and released falling 100s of metres to a turbine where it generates electricity.

Hope that helps.

what is the wavelength of radio waves transmitted by an FM station at 90MHz where 1M=10^6, and speed of radiowave is 3*10^8m/s

Igoryamba

Answer:

λ = 3.33 m

Explanation:

Given:

Frequency = f = 9 × 10⁷ Hz

Speed = v = 3 × 10⁸ m/s

Required:

Wavelength = λ = ?

Formula:

v = fλ

Solution:

Putting the givens in the formula

v = fλ

λ = $\frac{v}{f}$

λ = $\frac{3*10^8}{9*10^7}$

λ = 0.33 × 10¹

λ = 3.33 m

Which circuit offers the greater resistance to the battery, two bulbs in series or two bulbs in parallel?

dolphi86 [110]

The resistance of two things in series is the SUM of their individual resistances. So the resistance of two bulbs in series is double the resistance of one bulb.

(If they're in parallel, their combined resistance is 1/2 the resistance of one bulb.)

So two bulbs in series is the greater resistance. (a)
