Answer A, low energy and long wavelength.
The person still walked 16 blocks but ended up in the same spot he started from
Answer:
Net force = 13.36 N
Explanation:
Recall the formula for the force between two charges q1 ans q2 separated a distance "d" based on Coulomb's Law:
so, we need to calculate the force exerted on the charge 10 micro Coulombs by the 20 micro-Coulombs charge as they are separated 0.8 meters (haf the distance of the original two charges.
Notice that charges q1 and q3 are both positive charges so the force we obtain will be pointing in the direction towards charge q2. The magnitude of this is:
We can calculate now the force exerted by charge q2 on charge q3 using the same reasoning, and noticing that since charge q2 is negative, the force on q3 will be of attraction, then also pointing in the direction towards q2:
Now, we need to add both forces to get the final force (recall they are both in the same direction):
Net force = 10.547 N + 2.813 N = 13.36 N
Answer:
3.4 s is the correct answer to the given question .
Explanation:
As Given in the question
Vox=310 m/s
Voy=26 m/s.
As we know that
--------------eq(1)
As the velocity at the maximum height =0
Putting the value of in the equation(1) we get
Putting the value in the previous equation we get
Therefore h=3.4 s
Answer: Hello mate!
We want to find the average speed while the trucker was on the road, this average velocity is equal to the total distance divided by the total amount of time in the road.
The total distance is 2865 miles, and we know that the entire trip required 77 hours and 30 minutes, but there are 16 h and 30 min where spend sleeping and 3h 40min was used for meals, then the total amount of time in the road is:
77 hours and 30 mins - 3 hours and 40 mins - 16 hours and 30 mins
= 57 hours and 20 minutes of time in the road.
where we can write this in hours as 57.33 hours.
then the velocity in miles per hour is:
2856mi/57.33h = 49.8 miles per hour.
