A proton moves with a velocity of v with arrow = (3î − 5ĵ + k) m/s in a region in which the magnetic field is B with arrow = (î

Allisa [31]

Answer:

The magnitude of the magnetic force this particle experiences is $2.6\times10^{-9}\ N$ .

Explanation:

Given that,

Velocity v= (3i-5j+k) m/s

Magnetic field B=(i+2j-k) T

We need to calculate the value $\vec{v}\times\vec{B}$

$(\vec{v}\times\vec{B})=3i+4j+11k$

We need to calculate the magnitude of the magnetic force this particle experiences

Using formula of magnetic force

$\vec{F}=q(\vec{v}\times\vec{B})$

Put the value into the formula

$\vec{F}=1.6\times10^{-19}\times(3i+4j+11k)$

$\vec{F}=(4.8i+6.4j+1.76k)\times10^{-19}$

$|F|=2.6\times10^{-9}\ N$

Hence, The magnitude of the magnetic force this particle experiences is $2.6\times10^{-9}\ N$ .

A rocket-driven sled Sonic Wind No. 2, is used for investigating the physiological effects of large accelerations on people. It

rewona [7]

Answer:

The best single equation in order to fin the acceleration is

$a=v_f/t=250/2=125m/s^2$

Explanation:

The best single equation in order to find the acceleration is the following kinematics equation:

$v_f=v_o+at$

As the rocket start from the rest, the initial velocity value is zero. Then the acceleration value is:

$a=v_f/t=250/2=125m/s^2$
