Answer:

The number of turns in the solenoid is 1.95 x 10⁴.

Explanation:

given information:

the length of solenoid, L = 0.34 m

magnetic field, B = 6.5 T

current, I = 90 A

to find the number of turn in solenoid, we can start from the magnetic field equation,

B = μ₀nI, n = N/L

B = magnetic field (T)

μ₀ = permeability (4π × 10⁻⁷ T.m/A)

n = the number turn per unit length (turn/m)

I = current (A)

N = the number turn in solenoid

L = the length of solenoid

thus,

B = μ₀IN/L

N = B L/μ₀I

   = (6.5) (0.34)/(4π × 10⁻⁷) (90)

   = 1.95 x 10⁴ turn

Answer:

The answer to your question is: Element

Explanation:

Question 1. The atomic number or proton number of an atom has the symbol Z. This number indicates the number of protons and element has. Each elelement has a specific atomic number, two different atomic numbers mean 2 different elements.

From the options given, we conclude that the element is different.

1. A bicycle initially moving with a velocity
ki77a [65]

Answer:

\boxed {\boxed {\sf 15 \ m/s \ or \ 15 \ m*s^{-1}}}

Explanation:

We are asked to find the final velocity. We are given the acceleration, time, and initial velocity, so we can use the following kinematics formula.

v_f= v_i+ at

In this formula, v_f is the final velocity, v_i is the initial velocity, a is the acceleration, and t is the time.

The bicycle has an initial velocity of 5.0 m *s⁻¹ or m/s, acceleration of 2 m/s², and a time of 5 seconds.

\bullet \  v_i = 5.0 \ m/s \\\bullet \  a= 2\ m/s^2\\\bullet \  t= 5  \ s

Substitute the values into the formula.

v_f=5.0 \ m/s + ( 2\ m/s^2 * 5 \ s)

Solve inside the parentheses.

  • \frac {2 \ m}{s^2}* 5 \ s = \frac{ 2 \ m}{s} * 5 = \frac{ 10 \ m}{s} = 10 \ m/s

v_f= 5.0 \ m/s + (10 \ m/s)

Add.

v_f= 15 \ m/s

The units can also be written as:

v_f= 15 \ m*s^{-1}

The bicycle's final velocity is 15 meters per second.

A 650 × 10–4 F capacitor stores 24 × 10–3 of charge.
alexgriva [62]

C. 0.37V. A capacitor of 650x10⁻⁴F that stores 24x10⁻³C has a potential difference of 0.37V between its plates.

The key to solve this problem is using the capacitance equation C = Q/Vᵃᵇ, where C is the capacitance, Q the charge stored in the plates, and Vᵃᵇ the potential difference between the plates.

A 650x10⁻⁴F capacitor stores 24x10⁻³C, clear Vᵃᵇ for the equation:

C = Q/Vᵃᵇ -----------> Vᵃᵇ = Q/C

Solving

Vᵃᵇ = 24x10⁻³C/650x10⁻⁴F = 0.37V
