Neutrons

Explanation:

Atoms of the same elements are called isotopes. They differ from other atoms in the number of neutrons they posses. They share the same chemical properties but only differ with regards to their mass number.

  • Isotopy is a phenomenon whereby an atom of an element exist in more than one form but they have the same atomic number.
  • Atoms of such element only differ in the number of neutrons they contain.
  • Since the mass number of an atom is the sum of protons and neutrons, they differ in this number too
  • Isotopes have the same chemical properties.

Which of the following changes will always increase the efficiency of a thermodynamic engine? Choose all correct statements.
Ilya [14]

Answer:B,C,D

Explanation:

Thermodynamic  efficiency is given by

\eta =1-\frac{T_C}{T-H}

\eta efficiency can be increased by Keeping _c constant and increasing T_H

Keeping T_H constant and decreasing T_c

by increasing \Delta T=T_H-T_c

by decreasing \frac{T_C}{T_H} ratio

(a) The stick is supported by a sharp point at the middle. On the left side, a weight of 100 g is suspended at 40 cm from the mi
Jet001 [13]

Answer:

20cm

Explanation:

Hello!

remember that the condition for a body to be at rest is that the sum of its moments and its forces be zero,

To solve this problem you must draw the free body diagram of the stick (attached image) and sum up moments at point 0 (where the sharp is located), which results in the following equation

(100g)(40cm)=x(200g)

X=\frac{(100)(40)}{(200)} =20cm
