A 1 530-kg automobile has a wheel base (the distance between the axles) of 2.70 m. The automobile's center of mass is on the cen
NeTakaya

Answer:

Force on front axle = 6392.85 N

Force on rear axle = 8616.45 N

Explanation:

As we know that the weight of the car is balanced by the normal force on the front wheel and rear wheels

Now we know that

F_1 + F_2 = W

F_1 + F_2 = (1530\times 9.81)

F_1 + F_2 = 15009.3 N

now we know that distance between the axis is 2.70 m and centre of mass is 1.15 m behind front axle

so we can write torque balance about its center of mass

F_1(1.15) = F_2(2.70 - 1.15)

F_1 = 1.35 F_2

now from above equation

F_2 + 1.35F_2 = 15009.3

now we have

F_2 = 6392.85 N

now the other force is given as

F_1 = 8616.45 N

Why does the emission of an alpha particle always result in transmutation?
prohojiy [21]

Explanation:

some radioactive isotope are present as terrestrial radiation other radioactive isotope are produced by humans via nuclear reactions which is result in unstable combination of neutrons and proton one way of artificially inducing nuclear transmutation is by bombarding stable isotopes with alpha particles

The force of attraction between the opposite charges of the ions in an ionic compound
Contact [7]

The force of attraction between the opposite charges of the ions in an ionic compound is an ionic bond.

<u>Explanation:</u>

The transfer process of valence electron between atoms referred as ionic bond. This is a kind of chemical bonds which can create two oppositely charged ions. In the presence of ionic bonds, the metal loses electrons and becomes a positive charge cation, while non-metal accepts these electrons and becomes a negative charge anion.

Here, more than 1 electron can be emitted or received to meet the octet principle and the net charge of the compound should be zero. For example: Table salt. In this compound, sodium loses the electron to become N a^{+}, while the chlorine loses the electron to become c l^{-}.

What is atmospheric pressure ? How can we calculate it?
rodikova [14]

Pressure exerted by means of an Earth's atmosphere.

<u>Explanation:</u>

Atmospheric pressure is also termed as barometric pressure, that is the pressure exist in the Earth's atmosphere, in other words it is the pressure wielded by the atmosphere's weight.

 1 atmosphere = 760 mm Hg

Atmospheric pressure could be measured using the equation,

Atmospheric pressure = Mercury's density × acceleration through gravity × the height of mercury column.

It can be measured or given in terms of Pa, torr. atm, psi, mm Hg and so on.

How are work and power related<br> to each other?
Fiesta28 [93]
They are related because work is an activity involving a force on an object and the distance traversed by the  object due to the force.
Power is the work done in unit time. 
Energy is able to do work and work changes the energy of objects. The power keeps the work going. 
For example if a object has energy of x joule it can perform x joule work.

Hope this helped :)
Have a great day
