Answer:
Explanation:
For resistance the formula is as follows
R = ρ L/S
where L is length of the wire , ρ is a constant for a specific material called specific resistance and S is cross sectional area .
For 0.6 m wire , putting the values
.13 = ρ x 0.6 / S
For unknown wire
R = ρ x 187 / S
Dividing the two equations
R / .13 = 187 / .6
R = (.13 x 187) / .6
= 40.5 ohms .
Answer:
Radio emissions of hydrogen and OH molecules
Explanation:
Water hole is a quiet region of the electromagnetic spectrum
Answer: Temperature inversion
Explanation: Temperature inversion is a reverse of the normal temperature flow or distribution of the air,it usually causes temperature to rise as altitude increase towards the troposphere instead of reduction of temperature.
Temperature inversion is caused when warm,dense air flow above cold,less dense air. Temperature inversion is hazardous to man as it traps pollutants close to the Earth surface,this condition limits vertical circulation.
A fatter handle. This allows you to provide more torque to the screw, which should eventually loosen it.
