Because liquids with low surface tension spread easily, and therefore are easier to apply to cuts and wounds.
Answer:
R = 7 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance. In this way, we have the following equation.
V = I*R
where:
V = voltage = 49 [V] (units of volts)
I = current = 7 [amp] (amperes)
R = resistance [ohms]
Now clearing R.
R =V/I
R = 49/7
R = 7 [amp]
95-2.30+0.1+0.02cm =0.00089186
100m
Answer:
P =105.44 W
Explanation:
Given that
D= 10 cm ,L= 60 cm
d= 0.1 cm ,B= 6.4 mT
ρ= 1.7 x 10⁻⁸ Ω · m
The number of turns N
N= L/d
N= 60/0.1 = 600 turns
Length of wire
Lc= πDN
Lc= 3.14 x 0.1 x 600
Lc=188.4 m
The magnetic filed given as


Now by putting the values

I=5.09 A
The resistance R given as




R=4.07 Ω
Power P
p =I²R
P= 5.09² x 4.07 W
P =105.44 W
Answer:
The correct answer is 2
