What is lighter than a feather but the strongest man can't hold for 5 minutes​

What is the value of the expression i 0 × i 1 × i 2 × i 3 × i 4? 1 –1 i –i

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

Can someone answer this question for me
