Answer:

The acceleration of the plane is -2.14 m/s² ⇒ 2nd answer

Explanation:

Acceleration is the rate of change of velocity

The unit for acceleration is meters per second square

The rule of the acceleration is: → $a=\frac{v-u}{t}$

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

→ $a=\frac{230-245}{7}$

→ $a=\frac{-15}{7}=-2.14$

→ The acceleration is -2.14 m/s²

The acceleration of the plane is -2.14 m/s²

The match making one is Radiation is i think B and Convection i think is C and Conduction i think is A. I think 1 is radiation. Because radiation is transferred between objects or an empty space. Number 2 i think is conduction Because conduction is the transfer of thermal energy between to objects touching. Number 3 i also i think is radiation because radiation transfers between objects. Number 4 i also think is conduction because the spoon was touching a hot pot that was on the stove so then the thermal energy was transferred between the two objects touching. number 5 I think is convection because convection is the transfer of energy by the movement of a fluid, such as air or water. Number 6 i think is radiation because the snake is not touching the lamp and radiation goes all across spaces. Number 7 i think is convection because convection is the movement of a fluid, such as air or water. Hope this helps sorry its so long :)

Differentiate between sound waves and seismic waves?

algol13

The only real difference is that common seismic waves travel through the ground and sound waves travel through the air. If you had a pipe attached to granite and you were listening to it, you might detect both.
