Answer:
The answer is Option A...
The current through R equals the current through R1
Answer:
Explanation:
Kinetic energy gained by alpha particle
= charge x potential difference
1/2 mv² = 3.2 x 10⁻¹⁹ x 3.45 x 10⁻³
.5 x 6.68 x 10⁻²⁷ V² = 11.04 x 10⁻²²
V² = 3.3 x 10⁵
V = 5.74 x 100
= 574 m / s
Mechanical energy is conserved in respect of A , C and D .
Part B
B , C, are unknown .
Answer:
Reorder the steps so that step 4 appears before step 3
Explanation:
In a nuclear power plant, we have;
1) Nuclear reaction between the radio active species and the particles takes place to generate energy in the nucleus of atoms
2) The nuclear energy in the atom is converted into radiant energy, which is the energy found in light, and thermal (heat) energy
3) The produced radiant and thermal energy is released as heat and light
4) With the produced heat, steam is generated
5) The generated steam turns the steam turbines and produced mechanical energy
6) The produced mechanical energy is then converted into electrical energy in the electrical generator of the power plant
To correct Savion's error, Step 4) the light and heat should be released before step 3) the released heat can be used to generate steam, we therefore reorder the steps so that step 4 appears before step 3.
Answer: B) Light
Explanation: light waves are Electromagnetic waves. Visible light is one of the many types of electromagnetic waves. The others are mechanical waves.
The answer is when GAS IS BURNED because when gas is burned, it cannot return into its previous state. Also, new substances are formed.
