The frequency of an x-ray wave is 3.0 x 1012MHz. Its wave speed is 3.0x 108m/s. Calculate the wavelength of the x-ray wave below
jasenka [17]

Answer: The wavelength of the x-ray wave is 10^{-10}m

Explanation:

To calculate the wavelength of light, we use the equation:

\lambda=\frac{c}{\nu}

where,

\lambda = wavelength of the light  = ?

c = speed of x-ray= 3.0\times 10^8m/s

\nu = frequency of x-ray = 3.0\times 10^{12}MHz=3.0\times 10^{18}Hz= 3.0\times 10^{18}s^{-1}     (1Hz=1s^{-1})

Putting in the values:

\lambda=\frac{3.0\times 10^8m/s}{3.0\times 10^{18}s^{-1}}=10^{-10}m

Thus the wavelength of the x-ray wave is 10^{-10}m

Suppose an object is moving through space in a straight line. What could cause the object to start moving in a circle?
MAVERICK [17]
It could pass by a large enough object that has enough gravity to pull the object into its orbit and the object would stay in orbit because it has centripetal force.

What are the major storage reservoirs of carbon
AVprozaik [17]

Answer:

Check Explanation.

Explanation:

When we are talking about the reservoirs of carbon we mean the places where carbon are been stored. So, we will be considering the places where carbon can be stored in our planet. Remember that carbon is the 6th element in the periodic table or chart.

Within these Reservoirs, the carbon moves from one to another and that is called Carbon cycle. The reservoirs of carbon can be in the atmosphere, the lithosphere and in the biosphere.

(1). Carbon can be stored in the atmosphere as Carbondioxide,CO2.

(2). Carbon can be found on lithosphere in sedimentary rock such as limestone. Also, as components in fossil fuels.

(3). Carbon can be found in the biosphere as soil carbon.

describe how climate over long periods of time have changed and predict how these changes will affect the future
kotykmax [81]
Future changes are expected to include a warmer atmosphere, a warmer and more acidic ocean, higher sea levels, and larger changes in precipitation patterns. The extent of future climate change depends on what we do now to reduce greenhouse gas emissions. The more we emit, the larger future changes will be
