The heat in the core of the Earth has several sources including:
1- The heat produced from the decaying of radioactive elements
2- The heat that was originally produced during the formation and accretion of the planet itself (This heat has not yet faded)
3- The heat produced during friction when denser material and elements sink into the planet's center.
Use the formula E=hv, h=plancks constant and v=frequency
use the formula c=v*lambda to find v
the answer will be 2.88*10^-23J
Answer:
The correct answer is - 4.9 kg x m/s^2.
Explanation:
The weight of any object is the mass of the object in specific gravity applied to the object. It can be represented by the F=ma where F is the force applied on the earth by the gravity (a) and mass of the object (m).
Solution:
F = ma
F = 0.5*9.8 kg x m/s^2.
= 4.9 kg x m/s^2.
Answer:
1). 4.00
2). 12.01
3). ? Sorry. Don't know and can't find.
Cellulose has more compound bonds. It comprises of numerous glucose atoms combined. Notwithstanding, we don't more often than not consider cellulose a sugar. It is all the more legitimately called a polysaccharide.
Cellulose is basically used to deliver paperboard and paper. Littler amounts are changed over into a wide assortment of subsidiary items, for example, cellophane and rayon.
