Answer:
9.8 Joules (rounded to 2 significant figures)
Explanation:
Work done (J)= Force(N) x distance changed (m)
- Force= 9.80665 x 0.5kg
- Force= 4.90332 Newtons
- Distance changed= 5-3
- distance changed= 2m/s
--> work done= 4.90332 x 2
work done= 9.8 Joules
Answer: Their final relative velocity is -0.412 m/s.
Explanation:
According to the law of conservation,
Putting the given values into the above formula as follows.
v = 
= -0.412 m/s
Thus, we can conclude that their final relative velocity is -0.412 m/s.
Answer:
nice!!! but did you know that geico can save you 15% or more on car insurance!
Explanation:
Answer:
a) -113 N/C
b) -423.71 V
Explanation:
The Step by step explanation and solution has been attached in the attachment section.
In option A there are two resistors in which two terminals of resistors are connected with the terminals of battery so here they are connected in parallel.
In option B all resistors and battery is connected in a single loop so it is a series combination of all.
In option C all three resistors are connected by their terminals to a single battery so here all three resistor are in parallel with the battery.
In option D only one resistor is connected in series with a battery as one single loop is there.
So in the above all cases two resistors are in parallel with battery in option A
