A uniform magnetic field of B = 6.31 T passes through a horizontal circular wire loop (r0 = 3.26 cm) at an angle LaTeX: \thetaθ = 17.3 degrees from the vertical. The radius of the loop is oscillating according to the equation LaTeX: r\left(t\right)=r_0\:\sin\left(\ome ga t\right)r ( t ) = r 0 sin ⁡ ( ω t ) with an angular frequency LaTeX: \omegaω of 1.75 rad/s. What is the equation for the time-dependent magnetic flux in terms of B, r0, t, LaTeX: \thetaθ, and LaTeX: \omegaω?

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

he answer is x=1x3 because x=1 to x=3
