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.

assuming that voltage remains constant, what happpens to the current in a wire as its diameter decreases?
Nataly_w [17]
A larger diameter wire has lower resistance. A lower resistance wire produces less heat for a given current flowing through it.

If a star has no measurable parallax, what can you infer?
AnnZ [28]
The star is FARTHER from Earth than the limit of our ability to measure parallax.

The NEAREST star outside the solar system has a parallax angle of 0.742 SECOND. That's like 0.000206 of a degree ! ALL other stars have SMALLER parallax.

I have no idea how they measure angles like these ... especially when the change in direction takes six months to happen !

In an out of control ceramics workshop, two clay balls collide in mid air and stick together. the first has mass 3.1 kg and coll
exis [7]
<span>We know that the first ball has a mass of 3.1 kg and moves at speed called V1 The second ball has a mass of M2 unknown and the both together moves a speed equal to V = V1/3

   The momentum keeps constant before and after balls collide, so:
 M1*V1 + M2*V2 = M*V
 3.1*V1 + M2*0 = (3.1+M2)*V1/3
 3.1*V1 = 3.1/3*V1+M2*V1/3
 3.1*V1-3.1/3*V1 = M2*V1/3
 (3.1-3.1/3)*V1 = M2*V1/3
 2*3.1/3 = M2/3
 M2 = 6.2
   Then the mass of the second ball is 6.2 kg</span>
