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:
t = 20.96 seconds
Explanation:
given,
lightning strikes at = 4.5 mi( 23,760 ft)
air temperature =74.0°F
74.0°F = 23.3 °C
speed of the sound at 23.3 °C
V = 331.5 + 0.6 × T
V = 331.5 + 0.6 × 23.3
= 345.48 m/s
distance given = 4.5 mile
1 mile = 1609.4
4.5 mile = 4.5 × 1609.4 = 7242.3 m
time taken =
t = 20.96 seconds
hence, time taken by the sound to reach by the observer is 20.96 sec.
Your question: What happens to particles in a surface wave (such as a water wave)?
My answer: B, They move perpendicular and parallel to the direction of wave motion.
Explanation: This is practically the answer the question below (or above me) tried to explain.
Astronomers suspected an eighth planet beyond Uranus because of the irregularities in the motion of Uranus suggested that gravity from another planet was affecting it.
<h3>Who is an astronaut?</h3>
It should be noted that an astronaut simply means an individual who is trained to travel in spacecrafts.
In this case, astronomers suspected an eighth planet beyond Uranus because of the irregularities in the motion of Uranus suggested that gravity from another planet was affecting it.
In mid-1800s, astronomers used the orbits of most asteroids to predict where a planet would have to be.
