Answer: the area of the pool.
Explanation:
Answer:
The magnitude of the magnetic force this particle experiences is 
.
Explanation:
Given that,
Velocity v= (3i-5j+k) m/s
Magnetic field B=(i+2j-k) T
We need to calculate the value 
We need to calculate the magnitude of the magnetic force this particle experiences
Using formula of magnetic force
Put the value into the formula
Hence, The magnitude of the magnetic force this particle experiences is .
A larger diameter wire has lower resistance. A lower resistance wire produces less heat for a given current flowing through it.
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 !
<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>
