A11) A solenoid of length 18 cm consists of closely spaced coils of wire wrapped tightly around a wooden core. The magnetic fiel

vitfil [10]

Answer:

Explanation:

From a Solenoid we know that a magnetic fiel is always inversely proportional to lenght L or BL = constant

$B= frac{\mu_0}{2R}$

As I is constant

$\frac{B2}{B1} = \frac{R1}{R2}$

$B2 = 2mT*\frac{18}{21}$

$B2 = 1.714mT$

A water rocket can reach a speed of 75 m/s in 0.050 seconds from launch. What is its average acceleration?

yanalaym [24]

A=v/t
So therefore 75/0.050= acceleration
So the answer is a= 1500 metres per second per second
