Answer:
1, 2, 4, 5, 6, 8
Explanation:
1. 2 N; 2 N
2. 200 N; 200 N
3. 200 N; 201 N
4. 2 N; 2 N; 4 N
5. 2 N; 2 N; 2 N
6. 2 N; 2 N; 3 N
7. 2 N; 2 N; 5 N
8. 200 N; 200 N; 5 N
The net force of the system should be 0 in order for the body to move at a constant velocity.
So, the options 1, 2, 4, 5, 6, 8 have net force equal to zero so they are possibly maintaining the speed of 256 m/s
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:
Fossil fuels release carbon dioxide into the atmosphere. Natural gas is the best fossil fuel in terms of energy output per unit of carbon dioxide emitted. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass has the approximate chemical formula CHO.
Explanation:
Answer:
Input work is the work done on a machine as the input force acts through the input distance .Other ways it would be the work done on a body or system, that is, forces that are applied to the body or system. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance. The machine does to the object to increase the output distance.
