Part A Find the x- and y-components of the infinitesimal electric field caused at the origin (x = 0) by one such segment at coordinate x
.
Enter the x
and y components of the electric field separated by a comma in terms of some or all of the variables Q, L, dx, x and the electric constant ϵ0.

Part B.
Find the x
- and y
-components of the total electric field caused at the origin by the rod.
Enter the x
and y components of the electric field separated by a comma in terms of some or all of the variables Q, L, dx, x and the electric constant ϵ0.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
