Answer:

Option C

Explanation:

The image given in the question represents an overflow tank

Since a water pump has rotor and blades (which is not visible in the given image), hence, this image is not of water pump.

The surge tank has a different structure as compared to that of overflow tank

Radiator looks like a metallic structure with parallel blades.

Hence, option C is correct

The specific gravity of a substance that has mass of 10 kg and occupies a volume of 0.02 m^3 is a) 0.5 b) 1.5 c) 2.5 d) 3.5 e) n

zhuklara [117]

Answer:

Specific gravity is 0.5 so option (a) is correct option

Explanation:

We have given mass of substance m =10 kg

Volume $V=0.02m^3$

Density of substance is given by $Density\ d=\frac{mass}{volume}=\frac{10}{0.02}=500kg/m^3$

Specific gravity is given by $specific\ gravity=\frac{density\ of\ substance}{density\ f\ water}=\frac{500}{1000}=0.5$

So option (a) is correct option

Assume the following LTI system where the input signal is an impulse train (i.e.,x(t)=∑????(t−nT0)[infinity]n=−[infinity].a)Find

Igoryamba

Answer:

See explaination

Explanation:

The Fourier transform of y(t) = x(t - to) is Y(w) = e- jwto X(w) . Therefore the magnitude spectrum of y(t) is given by

|Y(w)| = |X(w)|

The phase spectrum of y(t) is given by

<Y(w) = -wto + <X(w)

please kindly see attachment for the step by step solution of the given problem.
