Answer:

hello

Explanation:

for average speed the total distance is important so.

and you must convert min to hour 15 min is 1/4 or 0.25 hour

s =  \frac{x}{t}  =  \frac{12}{0.25}  = 48 \frac{km}{h}

for average velocity the straight line distance is important so

v =  \frac{d}{t}  =  \frac{8}{0.25}  = 32 \frac{km}{h}

hope you understand

If a roller coaster cart, with a mass of 100 kg, traveled this coaster, how much kinetic energy would it have at point 'E'?
zzz [600]

Answer:

Explanation:

Assuming no friction between the roller coaster car and the hill, and neglecting air resistance, the kinetic energy the roller coaster car would have at the bottom of the hill would be equal to its gravitational potential energy at the top of the hill, by conservation of energy.

Interference is an example of which aspect of electromagnetic radiation
Phantasy [73]

Answer:

We experience interference while listening to the radio. A radio station works by sending and receiving radio waves. Since the radio waves are being interfered with other waves which must have a wave nature.

The interference is the net result of two individual waves. It can be constructive or destructive interference and is the property of waves and not particles.

This interference is an example of electromagnetic radiation. Thus we experience wave behavior of electromagnetic radiation in our daily communications.

levacccp [35]

The microwave ovens rotate at a rate of about 0.105 rev/s.

The microwave rotation is the number of revolutions in a unit of time. To change the unit for angular velocity, assume that the quantity is multiplied by the unit it has. Then change to the desired units. The angular velocity is denoted by ω and has a magnitude of 6.3 rev/min.

ω = 6.3 rev/min

\omega = 6.3 \times \frac{1 \: rev}{1 \: min}

  • 1 minute = 60 seconds
  • The revolution unit didn't change

\omega = 6.3 \times \frac{1 \: rev}{60 \: seconds}

\omega = \frac{6.3 \: rev}{60 \: seconds}

ω = 0.105 rev/s
