Write an expression for the force exerted on a charge q which is moving at velocity v by: 1. An electric field E⃗ 2. A magnetic field B⃗ 3. If an electric field and a magnetic field are both present, would a force be exerted on the charge even if the charge were initially not moving? Explain your reasoning

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

A- a of 8.00 cm a of 34.0 nc. a , -, a of 25.0 nc is on of a of 15.0 cm .be toto aof ? a) b) c) j d) e)

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.
