Answer the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets
I hope it is helpful
here at the moment when bullet strikes the block it will have no external force on it
so here we can use momentum conservation
so we will have
so they move together with speed 1.98 m/s
Answer: The answer is 700kg
Explanation:
The change in temperature was [ (37) - (-5) ] = 42 Fahrenheit degrees.
Kelvins and Celsius degrees are 9/5 (or 1.8) the size of Fahrenheit degrees.
42 F-degrees / 1.8 K per F-degree =<em> 23 and 1/3</em> Kelvins.
<u>Check,</u> using °C = (5/9) (°F - 32) and K = 273.15 + °C :
-5° F = -20.566° C = 252.594 K.
+37° F = 2.778° C = 275.928 K
(275.928K - 252.594K) = <u>23.334 K</u> close enough yay !
