The levels of structural organization:
cell ---> tissue ---> organ ---> organ system ---> organism
A dog's eye would be an organ.
Answer:
No electromagnetic waves can not exists if changing magnetic field could produce electric fields but the changing electric fields could not produce magnetic fields. Electromagnetic waves are oscillating waves and they are based on this fact that the changing magnetic field produce electric field and the changing electric field produce the magnetic field. That is why these waves are known for self propagation and can even travel through vacuum. In this wave the electric field and the magnetic field lies perpendicular to each other. These waves travel with the speed of light and their example is light and other radiations coming from sun.
Weight tending to shear the pin is
W = 24.0 N
The shear area of the pin is
A = (π/4)*(2.0 x 10⁻³ m)² = 3.1416 x 10⁻⁶ m².
The shear stress is
τ = (24.0 N)/(3.1416 x 10⁻⁶ m²)
= 7.64 x 10⁶ Pa
= 7.64 MPa
Answer: 7.64 Mpa
Explanation:
Kepler's third law gives the relationship between the orbital radius and the orbital period of the planet. Its mathematical form is given by :
Here,
G is gravitational constant
M is mass of sun
It means that the mass of Sun is constant for all planets orbiting the sun, assuming circular orbits.
Answer:
I'm pretty sure its radiation and reflection. Some of the Sun's energy gets reflected off into space. (I could be wrong though)
