To solve this problem we will use two given concepts. The electric field in an atom and the electric field in the air. The first is a theoretical case whose value will be brought up while the second is given by the statement. We will divide the values and compare the proportion to obtain the respective conclusions. The electric field in an atom is

E = 5.75*10^{11}n/c

Dialectic strength of air is given as

E_d = 3*10^6 N/C

Hence the electric field in an atom cannot be less than the dialectic field strenth of air

Divide E and E_d, we have

\frac{E}{E_d} = \frac{5.75*10^{11}}{3*10^6}

E = (1.91*10^5)e_D

Thus the electric field of an atom is within and order of 10^5 the dialectic strength of air instead of factor 10^{10}

<em>Therefore the electric field in an atom is greater than the dialectic field strenth of air</em>

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 60.0 m/s , and it leav
nata0808 [166]

Answer:

F = -307.4 N

Explanation:

It is given that,

Mass of the baseball, m = 0.145 kg

Initial speed of the baseball, u = 60 m/s

Final speed of the baseball, v=65\ cos(30)=56.29\ m/s

Time of contact, t=1.75\ ms=1.75\times 10^{-3}\ s

(a) It is assumed to find the horizontal component of average force. It is given by :

F=m\dfrac{v-u}{t}

F=0.145\dfrac{56.29-60}{1.75\times 10^{-3}}

F = -307.4 N

So, the horizontal component of average force is 307.4 N. Hence, this is the required solution.

What ia the law of convesation of energy​
Free_Kalibri [48]
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
