Answer:
50volts
Explanation:
Each of the resistance is 10ohms. 2 in series and 2 in parallel. it means the 2 parallel can combines with total of 10×10÷(10+10)= 5ohms and combine in series with 10ohms which is 10+10+5= 25ohms. in series connection, we have same current flowing. therefore the voltage source will be 25ohms × 2amps = 50volts
Answer:
where L is the length of the ramp
Explanation:
Let L (m) be the length of the ramp, and g = 9.81 m/s2 be the gravitational acceleration acting downward. This g vector can be split into 2 components: parallel and perpendicular to the ramp.
The parallel component would have a magnitude of
We can use the following equation of motion to find out the final velocity of the book after sliding L m:
where v m/s is the final velocity, = 0m/s is the initial velocity when it starts from rest, a = 2.87 m/s2 is the acceleration, and is the distance traveled:
Answer: -39.2 m/s directed downwards
Explanation:
We can solve this problem with the following equation:
Where:
is the ball's velocity at 4 s
is the ball's intial velocity, since it was dropped from rest
is the acceleration due gravity, aways directed downwards
is the time
Solving:
Finally:
<u>The negative sign indicates the velocity is downwards</u>
