Answer:

a)115 N

b)For father acceleration = 1.69 m/s²

For son acceleration = 3.28 m/s²

Explanation:

Given that

Mass of man(M)= 68 kg

Mass of son (m)= 34 kg

F= 115 N

As we know that from third law of Newtons ,It sates that every action have it reaction in opposite direction but same in magnitude.

So the force exerted by boy on father = 115 N

From Newtons second law of motion

F= m a

F=Force

m= mass

a=acceleration

For father

115 = 68 x a

a=1.69 m/s²

For son

115  = 35 x a'

a'=3.28  m/s²

An ordinary flashlight battery has a potential difference of 1.2 V between its positive and negative terminals. How much work mu
Maru [420]

The work done to transport an electron from the positive to the negative terminal is 1.92×10⁻¹⁹ J.

Given:

Potential difference, V = 1.2 V

Charge on an electron, e = 1.6 × 10⁻¹⁹ C

Calculation:

We know that the work done to transport an electron from the positive to the negative terminal is given as:

W.D = (Charge on electron)×(Potential difference)

       = e × V

       = (1.6 × 10⁻¹⁹ C)×(1.2 V)

       = 1.92 × 10⁻¹⁹ J

Therefore, the work done in bringing the charge from the positive terminal to the negative terminal is 1.92 × 10⁻¹⁹ J.

Consider the circuit shown in the figure below. (Let R1 = 3.00 Ω, R2 = 8.00 Ω, and = 10.0 V.). . (a) Find the voltage across R1.
Goryan [66]
You take the inverse of the total resistances of each branch and add them up. So if you have 5ohm, 7 ohm, and 10ohm, you would add 1/5 + 1/7 + 1/10 = 31/70 Then flip it back by either using the <span>x<span>−1</span></span><span> (inverse) key on your calculator or simply dividing 70 by 31 to get a total of 2.26ohms</span>
