The amount of NOx emission produced by a household is required.

The total amount of NOx the household is responsible for is 91.06 kg.

1 car produces 11 kg of NOx per year.

Natural gas burning produces 4.3 g of NOx per therm.

Electric power plant produces 7.1 g of NOx per kwh.

2 cars will produce $2\times 11=22\ \text{kg}$ of NOx.

1200 therms of natural gas will produce $1200\times 4.3=5160\ \text{g}$

9000 kWh will produce $7.1\times 9000=63900\ \text{g}$

Converting all to kg and finding the total amount

$22+5.16+63.9=91.06\ \text{kg}$

The total amount of NOx the household is responsible for is 91.06 kg.

Car B has the same mass as Car A but is going twice as fast. If the same constant force brings both cars to a stop, how far will

evablogger [386]

Answer:four times

Explanation:

Given

mass of both cars A and B are same suppose m

but velocity of car B is same as of car A

Suppose velocity of car A is u

Velocity of car B is 2 u

A constant force is applied on both the cars such that they come to rest by travelling certain distance

using to find the distance traveled

where, v=final velocity

u=initial velocity

a=acceleration(offered by force)

s=displacement

final velocity is zero

For car A

$0-(u)^2=2\times a\times s$

$s_a=\frac{u^2}{2a}------1$

For car B

$0-(2u)^2=2\times a\times s_b$

$s_b=\frac{4u^2}{2a}----2$

divide 1 and 2 we get

$\frac{s_a}{s_b}=\frac{1}{4}$

thus $s_b=4\cdot s_a$

distance traveled by car B is four time of car A

A car is accelerating at a rate of 35 m/s2 and has a resulting velocity increase from 17 m/s to 26 m/s. How long did it take to

harina [27]

Answer:The answer is (60 mph - 0 mph) / 8s = (26.8224 m/s - 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared.

A long solenoid that has 1000 turns uniformly distributed over a length of 0.400 m produces a magnetic field of magnitude 1.00 ×

yKpoI14uk [10]

0.03185A current is required in the windings for that to occur.

Solenoids are essentially coils of cord. These generate a magnetic subject which strives a pressure over a steel element.A solenoid is a fundamental time period for a coil of cord that we use as an electromagnet.
We additionally consult with the tool which could convert electric power into mechanical power as a solenoid.

Actually it generates a magnetic subject for developing linear movement from the electrical cutting-edge. With using a magnetic subject.

Magnetic field at the centre of a solenoid of length 'L' having 'N' number of turns with a current 'I' is given by $B=\frac{u_0NI}{L}$ ...(1)

It is given that 1000 turns uniformly distributed over a length of 0.400 m produces a magnetic field of magnitude 1.00 ×10⁻⁴T .

Putting above values in equation (1) , we get

$1.00\times10^{-4}=\frac{4\pi \times10^{-7}\times1000I}{0.400} \\\\I=\frac{1.00\times10^{-4} \times0.400}{4\pi \times1000} \\\\I=0.03185A$
