What is internal resistance?</h3>
Internal resistance can be described as the resistance within a battery, or other voltage source, that causes a drop in the source voltage when there is a current.
The parameters given are :
Coil 1 = 50 turns
Coil 2 = 500 turns
Resistance 1 = 1022
Resistance 2 = 6002
Internal resistance = 50 ohms
Emf = 25v
I = 25/ 50+ 10
I = 25/60
I = 5/ 12 A
= 25/50+ 600
= 25/ 650
= 5/ 130 A
The ratio of the deflection when each is connected in turns to a cell of e.m. 25 V and internal resistance 50 ohms =
Q1/ Q2
Q1 = N1 x B x 
/ c
Q2 = N2 x B x / c
therefore Q/ Q2 = (50 x 5/12 )/ (500 x 5/130)
Q1 / Q2 = 12/ 13 which 13: 12
Therefore, The ratio of the deflection when each is connected in turns to a cell of e.m. 25 V and internal resistance 50 ohms is 13: 12.

Answer:
-2000 N
Explanation:
To solve the problem, we can use the impulse theorem, which states that the impulse is equal to the change in momentum of the car:
where
F is the average breaking force
is the stopping time
m = 1000 kg is the mass of the car
is the change in velocity of the car
Solving the equation for F,
Answer:
Number of electron wavelength will Double
Explanation:
let the radius = r and wavelength = λ
when R doubles and λ ( wavelength ) remains the same
The number of electron electron wavelengths will double as well
Using Bohr's angular momentum quantization to show this
attached below
The correct answer is forces are equal but opposite in direction between car and bus.
What do we mean by Collision?
When two objects collide, forces of equal magnitude and opposite direction are applied to each object. Such pressures frequently result in one thing gaining momentum and gaining speed while the other object slows down (lose momentum).
The force applied to an object to cause an impact—a change in momentum—on it is referred to as the impact force, or momentum. Technically speaking, the Car and the bus would have exerted and felt the same amount of impact force in the event of a collision. Because every action has a corresponding and opposing response, according to Newton's third law.
