When the reaction:

1 answer:

3 0

The last sentence is a little vague.
However, I will assume that by the last sentence you meant
$Reaction~Rate=[CH_3Cl][H_2O]$
The reaction order respective to any substance is the value of the exponent on that substance in the Reaction Rate equation.
We see that the exponent on both the substance is 1 so the reaction order with respect to each substance is 1.

Which of the following is correctly describes a radio wave

Zigmanuir [339]

AM radio has longer wavelength and lower frequency. "Short-wave" radio has shorter WL and higher FQ. Police walkie talkies have even shorter and higher. FM radio has even shorter and higher. Aircraft communication has even shorter and higher. TV has even shorter and higher. Cellular telephone has even shorter and higher. The radio waves is a microwave oven have even shorter and higher. Satellite TV signals into the dish on the garage have even shorter and higher.

Consider an electron that is 100 m from an alpha particle ( = 3.2 x 10-19 C). (Enter the magnitudes.) (a) What is the electric f

scoundrel [369]

Answer:

a) $E=2.88*10^{-13}N/C$

b) $E=1.44*10^{-13}N/C$

c) $F=4.61*10^{-32}N$

Explanation:

The definition of a electric field produced by a point charge is:

$E=k*q/r^2$

a)Electric Field due to the alpha particle:

$E=k*q_{alpha}/r^2=9*10^9*3.2*10^{-19}/(100)^2=2.88*10^{-13}N/C$

b)Electric Field due to the electron:

$E=k*q_{electron}/r^2=9*10^9*1.6*10^{-19}/(100})^2=1.44*10^{-13}N/C$

c)Electric Force on the alpha particle, on the electron:

The alpha particle and electron feel the same force magnitude but with opposite direction:

$F=k*q_{electron}*q_{alpha}/r^2=9*10^9*1.6*10^{-19}*3.2*10^{-19}/(100)^2=4.61*10^{-32}N$

under what conditions would a scale record a weight for an object which is equal to the magnitude of the gravitational force on

d1i1m1o1n [39]

In a non accelerated frame, also called inertial frame, when no additional forces are acting upon the body.

For instance, a scale in free fall will not record the weight, but zero, like the astronauts. But also, if someone is pulling the object or pushing it, the scale will record some other value.

List and explain briefly similarities and differences between the electric force between two charges and the gravitational force

bazaltina [42]

Answer:

Please see below as the answers are self-explanatory.

Explanation:

Similarities

1) The resultant force is along the line that joins both charges or both masses (assuming both objects can be represented as points)

2) Both type of forces obey Newton's 3rd law.

3) Both are proportional to the product of the property that is affected by the force (charges and masses)

4) Both obey an inverse - square law (consequence of our universe being three-dimensional)

Differences

1) Main difference, is that while the gravitational force is always attractive, the electrostatic force can be attractive or repulsive, as there are two types of charges, which attract each other being of different type, and repel each other if they are of the same type.

2) It is possible, artificially, to block the influence of the electrostatic force, shielding a room, for instance, which is not possible for the gravitational force.
