Answer:
500,000 hertz
Explanation:
Wavelength= 600 meters
Velocity(b) = 3 × 10^8
Frequency=?
Therefore the frequency can be calculated as follows
Velocity= frequency × wavelength
Frequency= 3 × 10^8/600
= 500,000 hertz
Hence the frequency is 500,000 hertz
Answer:
Yes
Explanation:
You included all the stages of matter and described each of them. You're outlining their properties and you've created a clear diagram (and by diagram I mean chart) of solids, liquids, and gas.
Answer:
Explanation:
(A) water proofing is designed to keep out soil moisture and liquid water through a concrete structure while damp proofing is a coating on the exterior of a structure so as to stop the transference of ground moisture through concrete.
(B) Water proofing is more appropriate when the water table of the region is higher and there is higher rainfall, it is also more appropriate when there is a presence of hydro-static pressure.
while
Damp proofing is more preferable when there is a drier climate, there is a lower water table, also when there is a well drained soil and also good gravity drain.
Answer:
Energy is:
A property that must be transferred to perform work.
