Answer:
nπ + π/2 for any integer n
Explanation:
Since destructive interference occurs every odd multiple of half wavelength, that is π/2, 3π/2, 5π/2 where the interference is half wavelength and in general, (n + 1/2)π where n is an integer. So, nπ + π/2 for any integer n
Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth.
Hope this helped! :)
Can I be brainliest please?
Answer:0.0909 kJ/K
Explanation:
Given
Temperature of hot Reservoir 
Temperature of cold Reservoir 
Heat of 100 kJ is transferred form hot reservoir to cold reservoir
Hot Reservoir is Rejecting heat therefore 
Heat is added to Reservoir therefore 
Entropy change for system



As entropy change is Positive therefore entropy Principle is satisfied
Answer:
5.33kg
Explanation:
Given parameters:
Velocity of eagle = 15m/s
Kinetic energy of the eagle = 600J
Unknown:
Mass of the eagle = ?
Solution:
The kinetic energy of any body is the energy due to the motion of a body. There are different forms of kinetic energy some of which are thermal, mechanical, electrical energy.
The formula of kinetic energy is given as;
Kinetic energy =
m v²
where m is the mass, V is the velocity
substitute the parameters in the equation;
600 =
x m x 15²
225m = 1200
m =
= 5.33kg
