David is driving a steady 26.0 m/s when he passes tina, who is sitting in her car at rest. tina begins to accelerate at a steady

nata0808 [166]

Relative speed of Tina with respect to David is given by

$v_r = v_t - v_d$

$v_r = 0 - 26$

$v_r = - 26 m/s$

now the acceleration of Tina with respect to David

$a_r = a_t - a_d$

$a_r = 2.80 - 0$

$a_r = 2.80 m/s^2$

now the relative displacement would be zero when Tina cross David

so now we have

$\deta x = 0 = v_r * t + \frac{1}{2} a_r t^2$

$0 = -26 * t + \frac{1}{2}*2.8*t^2$

$t = 18.6 s$

now the speed of Tina at this moment is given as

$v_f = v_i + a * t$

$v_f = 0 + 2.8 * 18.6$

$v_f = 52 m/s$

<em>so the speed will be 52 m/s</em>

A wire is formed into a circle having a diameter of 11.1 cm and is placed in a uniform magnetic field of 2.79 mT. The wire carri

Ber [7]

Answer:

Maximum torque on the wire is $1.34\times 10^{-4}\ N-m$

Explanation:

It is given that,

Diameter of the wire, d = 11.1 cm = 0.111 m

Radius of wire, r = 0.0555 m

Magnetic field, $B=2.79\ mT=0.00279\ T$

Current, I = 5 A

We need to find the maximum torque on the wire. Torque is given by :

$\tau=IAB\ sin\theta$

Torque is maximum when, $\theta=90$

$\tau=IAB$

$\tau=5\times \pi \times (0.0555)^2\times 0.00279$

$\tau=0.000134\ N-m$

$\tau=1.34\times 10^{-4}\ N-m$

So, the maximum toque on the wire is $1.34\times 10^{-4}\ N-m$ . Hence, this is the required solution.
