If u mean pressure, pressure = Force/Area
Correct me if I am wrong :D
Answer:
8 electrons in the third energy level
Explanation:
From the description,the third energy level has 8 electron (represented by the small green balls you describe)
Answer:
The radius of a chamber is 2.36 meters.
Explanation:
Given that,
The outer wall moves at a speed of 2.72 m/s.
Mass of the person, m = 75.1 kg
The person feels a force of 235 N force pressing against his back. The force acting on the person is centripetal force. It is given by the below formula :
r is the radius of a chamber
r = 2.36 meters
So, the radius of a chamber is 2.36 meters. Hence, this is the required solution.
<span>motion of truck constitutes of 3 travels.
1. accelerating uniformly with acceleration a1 = 2 m/s^2 until its velocity reached 20 m/s travelling a
distance of 's1' meters.
2. uniform motion with 20 m/s for a time duration t1 = 20s travelling a distance of 's2' meters.
3. uniform deceleration for t2 = 5 sec which stops the truck after travelling a distance of 's3' meters.. </span>
<span>Of course.
Throw a ball into the air. Right after you release it, the velocity is upward, but the acceleration is downward.
Later, the velocity falls to zero; the acceleration is still downward.
Still later, the velocity goes downward; the acceleration is still downward.</span>
