Answer:
1500 per second.
Explanation:
vibrations = 1.5 kilohertz
1.5×1000=1500
the answer is 1500 per second.
The answer is either A or D
Explanation:
Formula to calculate the electric potential is as follows.
Putting the given values into the above formula as follows.
= ![\frac{9 \times 10^{9}}{0.25}[\frac{-3.3}{\sqrt{2}} + 4.2] \times 10^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B9%20%5Ctimes%2010%5E%7B9%7D%7D%7B0.25%7D%5B%5Cfrac%7B-3.3%7D%7B%5Csqrt%7B2%7D%7D%20%2B%204.2%5D%20%5Ctimes%2010%5E%7B-6%7D)
= 
Hence, electric potential at point A is .
Now, the electric potential at point B is as follows.
= ![\frac{9 \times 10^{9}}{0.25} [-3.3 + \frac{4.2}{\sqrt{2}}] \times 10^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B9%20%5Ctimes%2010%5E%7B9%7D%7D%7B0.25%7D%20%5B-3.3%20%2B%20%5Cfrac%7B4.2%7D%7B%5Csqrt%7B2%7D%7D%5D%20%5Ctimes%2010%5E%7B-6%7D)
= 
Hence, electric potential at point B is .
Answer:
e
Explanation:
i took it myself and got it right
Explanation:
a) 7.5= 111.1×2°= 0.1111×2^3
which can also be written as
(1/2+1/4+1/8+1/16)×8
sign of mantissa:=0
Mantissa(9 bits): 111100000
sign of exponent: 0
Exponent(5 bits): 0011
the final for this is:011110000000011
b) -20.25= -10100.01×2^0= -0.1010001×2^5
sign of mantissa: 1
Mantissa(9 bits): 101000100
sign of exponent: 0
Exponent(5 bits): 00101
the final for this is:1101000100000101
c)-1/64= -.000001×2^0= -0.1×2^{-5}
sign of mantissa: 1
Mantissa(9 bits): 100000000
sign of exponent: 0
Exponent(5 bits): 00101
the final for this is:1100000000100101
