A person scuffing her feet on a wool rug on a dry day accumulates a net charge of -52 µc. how many excess electrons does this pe

LenKa [72]

Using q=1.60217662 E-19 C we get:
$\frac{52 \times 10^-^6}{1.60217662 \times 10^-^1^9}=3.24558 \times 10^1^4 electrons$
Then using 9.10938356E-31 kg as the mass, we get
$(3.24558 \times 10^1^4)(9.10938356\times 10^-^3^1)=2.95653\times 10^-^1^6kg$

An ideal gas is compressed at constant pressure p=1500 Pa from a volume Vi=0.4 m3 to Vf=0.25 m3. At the same time, heat is trans

Anon25 [30]

To solve this problem we will apply the first law of thermodynamics and we will make a balance between the heat transferred, its internal energy and the total work. Recall that for gases the definition of work can be expressed in terms of its pressure and volume. Let's start

$dQ = dU +dW$

Here,

dU = Internal Energy

dW = Work

But internal energy is unchanged, then

$dQ = dW$

$dQ = PdV$

Where

$dV$ = Change in Volume

P = Pressure

Finally, the expression of the heat transferred can be expressed in terms of pressure and volume, so it would end up becoming

$dQ = p(v_i-v_f)$

Replacing,

$dQ = (1500)(0.4-0.25)$

$dQ = 225J$

Therefore the correct answer is B.

A baton twirler has a baton of length 0.36 m with masses of 0.48 kg at each end. Assume the rod itself is massless. The rod is f

AleksAgata [21]

Answer:

Part a)

When rotated about the mid point

$\tau = 0.021Nm$

Part b)

When rotated about its one end

$\tau = 0.042 Nm$

Explanation:

As we know that the angular acceleration of the rod is rate of change in angular speed

so we will have

$\alpha = \frac{\Delta \omega}{\Delta t}$

$\alpha = \frac{2.4 - 0}{3.6}$

$\alpha = 0.67 rad/s^2$

Part a)

When rotated about the mid point

$I = 2mr^2$

$I = 2(0.48)(0.18)^2$

$I = 0.0311 kg m^2$

now torque is given as

$\tau = 0.0311 (0.67)$

$\tau = 0.021Nm$

Part b)

When rotated about its one end

$I = m(2r)^2$

$I = (0.48)(0.36)^2$

$I = 0.0622 kg m^2$

now torque is given as

$\tau = (0.0622)(0.67)$

$\tau = 0.042 Nm$
