The specific heats of aluminum and iron are 0.214 and 0.107 calories per gram degrees Celsius [cal/(g degrees Upper C)] respectively. If we add the same amount of energy to a cube of each material (of the same mass) and find that the temperature of the aluminum increases by 28 degrees Fahrenheit [degrees Upper F], how much will the iron temperature increase in degrees Fahrenheit [degrees Upper F]?

Describe the function of the endomembrane system? what organelles are involved?

Could someone . i have tried to solve myself but my calculation is off

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
