What happens to baking soda when you heat it up!
When you heat up baking soda, it loses carbon dioxide which tends to crest bubbles. This is what makes it quite light and fluffy.
Hope I helped :D
Answer:
The direction of the induced emf is revered, and hence the direction of the induced current.
Explanation:
When the polarity of the magnet is revered, the direction of the magnetic field is also reversed, and therefore, according to Faraday's law


since the magnetic field changes sign from
to
.
Hence, the effect is that the direction of the emf induced is reversed, which also reverses the direction of the induced current in the solenoid.
P.S:<em> The cause of confusion here is the direction of magnetic field lines from the magnetic</em>, and so you must remember that <em>field lines begin at the north pole and end at the south pole.</em>
Answer:
The acceleration of the plane is -2.14 m/s² ⇒ 2nd answer
Explanation:
<u><em>Acceleration</em></u> is the rate of change of velocity
The unit for acceleration is meters per second square
The rule of the acceleration is: → 
where a is the acceleration, u is the initial velocity, v is the final velocity
and t is the time
An airplane traveling 245 m/s east experiences turbulence so the pilot
slows down to 230 m/s
It takes the pilot 7 seconds to slow down to this speed
We need to find the acceleration of the plane
Lets use the rule above
→ u = 245 m/s , v = 230 m/s , t = 7 seconds
→ 
→ 
→ The acceleration is -2.14 m/s²
<em>The acceleration of the plane is -2.14 m/s²</em>
