Answer:
The property of the wave marked X is related to the source of the wave
Explanation:
The source of of origin of waves
Electromagnetic wave are waves that consists of varying electric and magnetic field that vibrate perpendicular to each other and to the direction of propagation of the wave and they are therefore transverse waves and transfer energy
Electromagnetic waves originate from the vibration of charged particles that gives off varying electric and magnetic fields
Mechanical waves are defined as waves that require a material medium such as air, water, metal, plastic, stretched leather, or wood to propagate
Mechanical waves originate from vibration of the particles of a medium
Sound waves which is a form of longitudinal mechanical waves that propagates by the vibration of the particles of a given medium about a point parallel to the direction of propagation of the wave.
Answer:
a military base with aliens simple
Explanation:
Answer:
Q=185.84C
Explanation:
We have to take into account the integral
In this case we have a superficial density in coordinate system.
Hence, we have for R: x2 + y2 ≤ 4
but, for symmetry:

Explanation:
mass of copper block = 0.3 kg at 77 K or -196 °C
Let mass of water taken be m ( maximum) , in this case we will have mixture of water and copper block at 0°C finally.
Heat gained by copper block
= msΔt
.3 x 196 x 385 J
heat lost by water to lower its temp fro 50°C to 0°C
= m x 4186 x 50
Heat lost = heat gained
m x 4186 x 50 = .3 x 196 x 385
m = 108.16 gm
Let mass of water taken be m ( minimum ) , in this case we will have mixture of ice and copper block at 0°C finally.
heat lost by water to lower its temp fro 50°C to 0°C
= m x 4186 x 50
heat lost by water to lower its temp from 0°C to 0°C ice
= m x latent heat of fusion
m x 3.35 x 10⁵
Total heat lost
= m x 3.35 x 10⁵ + m x 4186 x 50
= 544300 m
Heat gained by copper block
= msΔt
.3 x 196 x 385 J
Heat lost = heat gained
544300 m = .3 x 196 x 385 J
m = 41.6 gm
