When v= 4.8 m/s:

E.K=mv²/2
=3,1(4.8)²/2
=35.712J

when v= 2(4.8):

E.K=mv²/2
=3.1(9.6)²/2
=142.848J

How are magnets used in modern technology?

slava [35]

Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people's bodies.

Azaria's pet lizard runs a distance of 45 meters in 24 seconds. What is the speed of the lizard?

san4es73 [151]

Question:

Azaria's pet lizard runs a distance of 45 meters in 24 seconds. What is the speed of the lizard?

_________________________________________________

Solution:

We are given,

Distance = d = 45 m
Time = t = 24 s

Speed is given by:

Speed = s = d/t

Putting the given values,

s = (45 m)/(24 s)

=> s = 1.875 m/s
