While chopping down his father's cherry tree, george discovered that if he swung the axe with a speed of 25 m/s, it would embed

itself 2.3 cm into the tree before coming to a stop. if the axe head had a mass of 2.5 kg, how much force was the axe exerting on the tree?

<span>First we must find the amount of acceleration needed using the equation Vfinal^2 = Vinitial^2 + 2*Acceleration*distance => 0 = 25^2 + 2*Acceleration*0.025m => Acceleration = 13,587m/s^2. Plug this into Force = Mass*Acceleration equation => Force = 2.5*13,587 = 33,967.5N.</span>

A current of 0.92 a flows in a wire. how many electrons are flowing past any point in the wire per second? the charge on one ele
Fantom [35]
The current is defined as the ratio between the charge Q flowing through a certain point of a wire and the time interval, \Delta t:
I= \frac{Q}{\Delta t}
First we need to find the net charge flowing at a certain point of the wire in one second, \Delta t=1.0 s. Using I=0.92 A and re-arranging the previous equation, we find
Q=I \Delta t= (0.92 A)(1.0 s)=0.92 C

Now we know that each electron carries a charge of e=1.6 \cdot 10^{-19} C, so if we divide the charge Q flowing in the wire by the charge of one electron, we find the number of electron flowing in one second:
N= \frac{Q}{q} = \frac{0.92 C}{1.6 \cdot 10^{-19} C}=5.75 \cdot 10^{18}

An atom that has only one electron in its valence electron shell is ______ chemically reactive?
umka2103 [35]

The valence electrons are the electrons in the outermost electron shell of an atom.

Explanation:

The number of electrons in an atom's outermost valence shell governs its bondingbehaviour.

That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table.

Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration <span><span>s2</span><span>p6</span></span>.

This tendency is called the octet rule, because the bonded atoms have eight valence electrons.

Calculate specific heat of liquid if a 450. g iron block is heated to 98.0 C and then droped into a calorimeter with 125 g of un
Naya [18.7K]

Answer:

Specific heat of liquid 1.258 \ J/g^0C.

Explanation:

We know in thermal equilibrium :

Loss in heat by iron block = Gain in heat by liquid .

Specific heat of iron = 0.45 J/g^0C.  { source internet }

Now , loss in heat by iron block = mC_{iron}\Delta T=450\times 0.45\times 57.6=11664\ J.

Heat gain by liquid=mC_{liquid}\Delta T=450\times C_{liquid}\times 20.6=9270\times C_{liquid}.

Equating both we get :

C_{liquid}=1.258 \ J/g^0C.
