I'm pretty sure the answer would be that the metal is conductive, which travels through the copper wires.
Answer:
122 forenhieght
Explanation:
(50°C × 9/5) + 32 = 122°F
Answer:
The correct answer is 4
Explanation:
Boron trifluoride (BF₃) has a molecular geometry (as shown in the image in the question) referred to as trigonal planar; this is because each of the the fluorine atoms/molecules (bonded to the central boron atom) is placed in such a way that they form the three "end points"/"domains" of an equilateral triangle. Hence, the correct option is the last option.
Answer:
The tension in the string is 78.73 N.
Explanation:
The tension in the string can be determined from the expression;
v = 
where: v is the speed of the wave in the sting, T is the tension in the string and m is the mass per unit length of the sting.
Given that: v = 16.2 m/s, and m = 0.3 kg/m.
Then;
16.2 = 
Square both sides to have,
= 
T =
x 0.3
= 252.44 x 0.3
= 78.732
T = 78.732 N
The tension in the string is 78.73 N.
