Answer:
i dont see an atom. or are you talking about any atom?
Answer:
Given:
radius of the coil, R = 6 cm = 0.06 m
current in the coil, I = 2.65 A
Magnetic field at the center, B =
Solution:
To find the number of turns, N, we use the given formula:
Therefore,
N = 22.74 = 23 turns (approx)
Answer:
0.0018 V
Explanation:
According to the law of conservation of energy, the kinetic energy gained by the particle is equal to the electric potential energy lost:
where
is the mass of the particle
is the final speed of the particle
q = -2.7 C is the charge
is the potential difference between the two points
Solving for , we find
The particle has been accelerated by this potential difference: since it is a negative charge, it means that the particle has moved from a point at lower potential towards a point of higher potential.
So, since the initial point is A and the final point is B, the result is
Answer:
R (120) = 940Ω
Explanation:
The variation in resistance with temperature is linear in metals
ΔR (T) = R₀ α ΔT
where α is the coefficient of variation of resistance with temperature, in this case α = -0,0005 / ºC
let's calculate
ΔR = 1000 (-0,0005) (120-0)
ΔR = -60
Ω
ΔR = R (120) + R (0) = -60
R (120) = -60 + R (0)
R (120) = -60 + 1000
R (120) = 940Ω
The magnitude of the average acceleration of the ball during this time interval will be 1969.69 m/s².
<h3>What is acceleration?</h3>
The rate of velocity change concerning time is known as acceleration.
Given data;
Initial velocity, u= 27.5 m/s
Rebound velocity, v= 21.0 m/s
Time elapsed, t = 3.30 × 10⁻³ seconds.
To find ;
Average acceleration, a
The average acceleration when the change in velocity is observed by the formula as:
Substitute the given values:
Hence, the magnitude of the average acceleration of the ball during this time interval will be 1969.69 m/s².
