A proton has a magnetic field due to its spin on its axis. the field is similar to that created by a circular current loop 0.650

Aloiza [94]

Answer:

$\tau=3.48*10^{-26}Nm$

Explanation:

The torque equation is given by:

$\tau=IABsin(\theta)$

Where:

I is the current
A is the area of the loop (A=πR²)
θ is the angle between the normal vector of A and B, in this case it is 90 degrees

So:

$\tau=1.05*10^{4}*\pi *(0.65*10^{-15})^{2}*2.5$

Therefore the torque is:

$\tau=3.48*10^{-26}Nm$

I hope it helps you!

Can someone explain with steps please

Answer:

The speed of other projectile is $3.1m/s$

Explanation:

Range of projectile is given by the equation

$\mathrm{R}=\frac{\mathrm{u}^{2} \cdot \sin 2 \theta}{\mathrm{g}}$

Here we have same range

Hence

$\frac{\mathrm{2.5}^{2} \cdot \sin (2 \times 65)}{\mathrm{g}}=\frac{\mathrm{u}^{2} \cdot \sin (2 \times 15)}{\mathrm{g}}\\\\u^2=\frac{2.5^2\sin130}{\sin30} \\\\u=3.10m/s$
