Answer:
7A
Explanation:
Current I = potential difference V ÷ Resistance R
I = V/R ........1
The overall resistance of parallel resistors is;
1/Rt = 1/R1 + 1/R2 ........2
Given;
V = 10V
R1 = 2 ohms
R2 = 5 ohms
Substituting the values into equation 2, to calculate the overall resistance;
1/Rt = 1/2 + 1/5
1/Rt = 7/10
Rt = 10/7 ohms
From equation 1, we can solve for the total current;
I = V/Rt = 10/(10/7)
I = 7A
The total current I flowing through a system is 7A
The strength of the thrust is 122 newtons.
The motion of the rocket is described by the second Newton's law, whose model is shown below:
(1)
Where:
- Thrust, in newtons
- Drag, in newtons
- Mass of the rocket, in kilograms
- Net acceleration of the rocket, in meters per square second
If we know that
,
and
, then the strength of the thrust is:



The strength of the thrust is 122 newtons.

For number 2:
Speed is related to kinetic energy because kinetic energy is the energy of motion.
Hope this helped!
BAH! Took me forever to think of it.
The Scientific method.
Brainliest please. :D
