I think it’s D but i’m not too sure
I would use a resistor rated for 1 W or more. Not less.
Answer:
Explanation:
(a) The applied force has two components Fx and Fy. The Fx component is the only one that does work
(b) There in no net force in the vertical component
(c)
(d)
I attached an scheme of the force diagram
D.
50 mph - 30 mph= 20 mph net velocity
change.
20mph/3600 seconds/hour= .00555 MPS
.0055 miles per second
40 seconds to complete the change
.0055/40= .000138
Answer:
Statement:
The electric current passing through a conductor is directly proportional to the potential difference across its ends provided temperature and other physical conditions remain constant.
Explanation:
Current is directly proportional to voltage loss through a resistor. That is, if the current doubles, then so does the voltage. To make a current flow through a resistance there must be a voltage across that resistance. Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R).
V∝I or I∝V⇒V=IR.
