Answer:
By the information provided we can find the cars speed.
Explanation:
- Speed is the distance traveled by any object in certain time. As we have distance traveled by car as 30 miles.
- And time taken by car to travel 30 miles is half an hour. So speed is easily calculated as,
. - Velocity is a vector quantity so we cannot determine velocity by knowing only distance and time, we need additional information of direction to know cars velocity.
- So the speed will be,
.

So, I'd go for a here.
The answer to the first one is sublimation.
In a series circuit, all devices are constrained to a single flow of current. There can only be a single value for the current for all devices, otherwise this would violate the conservation of charge. Therefore the current must be the same across each resistor.
<h3>The answer is D.</h3>
