Answer:

3.3\times 10^8\ btu/yr=11\ kW

Explanation:

Btu of British thermal unit is a unit of heat. The relation between btu/year and watts is given by :

1\ btu/yr=3.343\times 10^{-5}\ W\\\\3.3\times 10^8\ btu/yr=3.343\times 10^{-5}\times 3.3\times 10^8\ W\\\\3.3\times 10^8\ btu/yr=11031.9\ W\\\\3.3\times 10^8\ btu/yr=11\ kW

So,  3.3\times 10^8\ btu/yr is equal to 11 kW. Hence, the correct option is (d).

how many bits are required to sample an incoming signal 4000 times per second using 64 different amplitude level
Gelneren [198K]

Answer:

6 bits

Explanation:

The quality of digitized signal can be improved by reducing quantizing error. This is done by increasing the number of amplitude levels, thereby minimizing the difference between the levels and hence producing a smoother signal.

Also, Sampling frequently (also known as oversampling) can help in improving signal quality.

To get the number of bits, we use:

2ⁿ = amplitude level

where n is the number of bits.

Given an amplitude level of 64, hence:

2ⁿ = 64

2ⁿ = 2⁶

n = 6 bits

The velocity of money is a the same thing as the long-term growth rate of the money supply. b the money supply divided by nomina
tia_tia [17]

b the money supply divided by nominal GDP

Explanation:

The velocity of money is nothing but the ratio of GDP and money supply. In other words, velocity of money also tells us the rate at which money is being exchanged in a country. The constant velocity says that the growth rate in the economy is zero. Velocity of money depends on the rate at which money is spent for finished goods and services per unit time. It is more when spending of money is more and it decreases when people spend less money. The total amount of money that is in circulation or that exists in a country is know as money supply.

A person is filling a knee-high bucket with water using a garden hose and holding it such that water discharges from the hose at
Serggg [28]

Answer:

Yes i am agree with this suggestion

Explanation:

Given that we have to assume that there is no any frictional affects.

As we know that when height increases then the discharge level will decreases when discharge level decreases then the time of filling for the bucket will increase.So the  bucket will fill faster if the hose lowered until knee level.

Yes i am agree with this suggestion
