Answer:
I think it would be interviewing the researchers I'm unsure though
Answer:
A
The current through the solution is
B
The current is moving from B to A
Explanation:
From the question we are told that
The number of that move from A to B is
The time taken to move from A to B
Since the value of 1 charge is
The quantity of charge Q that flow from A to B is mathematically given as
The number of that move from A to B is
Since time taken to move from A to B is equal to time taken to move from B to A
The quantity of charge Q that flow from B to A is mathematically given as
The total quantity of charge is
The current flowing through the solution is
The flow is from B to A cause current flow from the positive terminal to negative terminal
(a.) The acceleration of the car can be calculated using the equation,
2ad = v²
Substituting,
2(a)(180 m) = (22.2 m/s)²
From the equation above, we achieve the value of a = 1.369 m/s²
(b) The force necessary is calculated below,
F = (1,300 kg)(1.369 m/s²)
F = 1,779.7 N
(c) Coefficient of friction,
1,779.7 N = (1,300)(9.81)(x)
The value of x from the generated equation,
x = 0.14.
A. The average kinetic energy of their particles is the same.
Explanation:
The temperature of an object is proportional to the average kinetic energy of its particles, following the relationship:
where
is the average kinetic energy of the particles
k is the Boltzmann constant
T is the absolute temperature
From this relationship, therefore, we see that the average kinetic energy of the particles in a substance depends only on its temperature: therefore, since the two pieces of iron have same temperature, they also have same average kinetic energy.
