A horizontal rod 0.250 m long is mounted on a balance and carries a current. At the location of the rod a uniform horizontal mag
Karo-lina-s [1.5K]

Answer:

The current is 7.87 A.

Explanation:

Given that,

Length = 0.250 m

Magnetic field B= 6.10\times10^{-2}\ T

Magnetic force = 0.120 N

We need to calculate the current

Using formula of magnetic force

F=BIL

I=\dfrac{F}{BL}

Where, B = magnetic field

I = current

l = length

F = force

Put the value into the formula

I=\dfrac{0.120}{6.10\times10^{-2}\times0.250}

I=7.87\ A

Hence, The current is 7.87 A.

zlopas [31]

Explanation:

formula: Vi = Vf - (at)

Vi: intial velocity

Vf: final velocity

a: acceleration

t: time

fill in formula with the numbers you are given

Vi= 41.6m - ((9.81 m/s^2)(1.89s))

parenthesis first according to pemdas

Vi= 41.6m - 18.54m/s

Answer: 23.06m/s

disclaimer: I havent done physics in awhile so I have no idea if this is right. just an attempt to help steer you in the right direction hopefully. good luck
