Answer:

A compound is a pure substance made of two or more elements chemically combined in a set ratio. ... If a different ratio of carbon atoms and oxygen atoms are seen in a formula, you have a different compound. For example, carbon monoxide—a gas produced in car engines—has the formula CO.

Answer:

Carbon monoxide is a highly poisonous, odorless, colorless, and tasteless gas. It is very flammable in air over a wide range of concentrations and burns in air with a bright blue flame . It becomes a liquid at 81.62 K.

the elements in the compound carbon and oxygen.

oxygen is also colorless, odorless and tasteless gas but it's not poisonous.

as we use it for breathing purpose whereas too much oxygen can be toxic.

carbon is solid and very brittle. diamond and graphite are two most common forms of carbon.

When elements are chemically combined, they form compounds having properties that are different from those of the uncombined elements

A helicopter flies 168 miles against the wind in 2 hours; with the wind, it can fly 252 miles in the same amount of time. find t

posledela

Let $v_h$ be the speed of the helicopter in still air. Let $v_w$ be the speed of the wind. Then, from the given information,

$(v_h-v_w)2=168\\ (v_h+v_w)2=252\\$

Adding the above 2 equations,

$4v_h=168+252\\ 4v_h=420\\ v_h=105$

The speed of the helicopter in still air $105 \;mi/hour$

The ratio of (new volume / old volume) is the same as the ratio of (new temperature / old temp).

Just remember that you have to use the ABSOLUTE temperatures.

An absolute temperature is (Celsius + 273).

The front brakes on a vehicle do more work than do the rear brakes. Technician A says that this is because the front wheel cylin

ludmilkaskok [199]

Answer:

Technician A says that this is because the front wheel cylinders are closer to the master cylinder than are the rear wheel cylinders.

Explanation:

Since the position of cylinder is near the front wheel so the normal force of the front wheel is more than the normal force on the rear wheel

as we know that the center of mass of the wheel is shifted towards the front wheel as the balancing is done with reference to its center of mass

so we will have

$N_1 d_1 = N_2 d_2$

also we have

$N_1 + N_2 = W$

so here we can say

friction force on front wheel will be more

$F_f = \mu N_1$

so here front wheel has to do more work to stop the vehicle

A cable might experience crosstalk, where the electrical signal bleeds from one wire pair to another, creating __________.

DochEvi [55]

A cable might experience crosstalk, where the electrical signal bleeds from one wire pair to another, creating interference.
Interference is the process in which two or more waves such as light, sound or electromagnetic waves of the same frequency combine to reinforce or cancel each other, the amplitude of the resulting wave being equal to the sum of the amplitudes of the combining waves.
