Answer:
A isolate the DNA From a sample of cells
Answer:
A switch opens or closes the electrical circuit, turning the flow of electricity on or off.
Explanation:
Angular velocity = (75x2pie)/60
=2.5pie ras^-1
linear velocity(or speed) at end of string, v = radius x angular velocity
v= 0.5 x 2.5pie
v=3.93 ms^-1
tension of string (I beleve is centeral force aplied by string), F= (mv^2)/r
F= (0.2 x 3.93^2)/0.5
F=6.18 N
(sorry if wrong)
Internal energy cannot be transferred whereas, thermal energy is the energy due to temperature difference
