Answer:
i have no idea what this is
Explanation:
<u>Answer</u>
D. 1,500 m/s
<u>Explanation</u>
the wave equation states that,
V = λf
Where V ⇒ Velocity
λ ⇒ wavelength
f ⇒ Frequency
F = 1/T
Where T ⇒ period
F = 1/0.006
= 166.667
∴ V = 9 × 166.667
= 1,500 m/s
The value of the c will be (0 i+0 j+0 k). c is a vector that is along the positive x-axis and has the condition a(b+c)=0.
<h3>What is a vector?</h3>
A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.
Given ;
a=3i-2j+k
b=-i-4j+3k
Given property:
a(b+c)=0
-i-4j+3k ((-i-4j+3k)+c)=0
(3+8+3)(-i-4j+3k)c=0
14(-i-4j+3k)c=0
c=0 i+0 j+0 k
Hence, the value of the c will be (0 i+0 j+0 k).

Answer:
I dont get what your asking. If u explaint to me what your asking ill tell you the answer in the comments.
Explanation:
Answer:
Iron has a higher heat capacity than copper
Explanation:
The heat capacity of a substance is defined as the amount of heat required to raise the temperature of an object by 1°C.
The higher the heat capacity of a substance, the longer the time it takes for the substance to become hot when heated.
Since the copper rod becomes too hot to hold much sooner than the iron rod, it means that iron has a higher heat capacity than copper.
