Answer:
Matthew throws a ball straight up into the air. It rises for a period of time and then begins to drop. At which points in the ball's journey will
gravity be the greatest force acting on the ball?
Explanation:
Answer:
B
Explanation:
Use conservation of momentum: Total momentum of the system before is the same as the total momentum after the collision. Since both are moving north, the momentum of both cars is in the same direction, and the total momentum before collision is 1000kg*20m/s + 1500kg*36m/s = 74000kg-m/s.
This is the same amount of momentum after collision, and since they are locked together, their mass is added. The velocity can be found by: 74000kg-m/s ÷ 2500kg = 29.6m/s.
momentum = mass*velocity
Answer:
Explanation:
Given that,
Mass of the amber bead, m = 12.6 g = 0.0126 kg
Charge on the bead,
The electric field due to infinite large plastic sheet is given by :
At equilibrium, q E = m g
where
is the charge per unit area on the glass sheet.
So, the charge per unit area on the glass sheet is (). Hence, this is the required solution.
Height increase h = R*(1 - cosΘ) = 1.2*(1-cos3.5°) = .00224 m.
<span>½Mbl*Vbl² = Mbl*g*h → </span>
<span>Vbl = √(2gh) = .2095 m/s </span>
<span>This is the initial velocity of the block. From momentum considerations, </span>
<span>Mbt*Vbt = Mbl*Vbl → </span>
<span>Vbt = (Mbl/Mbt)*Vbl = (5/.002)*.2095 = 523.8 m/s
this is what i think the answer is im not for sure though... hope it helps...</span>
<span>COGNITIVE bias describes when your likes and dislikes affect how you think about something.
Cognitive bias encompasses a lot of biases. This bias is identified as an objective thinking limitation because your brain perceives information based on your personal experience and preference.
A lot of people tend to think negatively of things and ideas that they deem impossible or improbable or they have not personally experienced. They tend to be closed minded thus their life experiences will be limited.
Another example is when you undergo a trauma in any time of your life, the long term effect would be that you veer away from situations that are similar to the situation that led to the traumatic event. Because you already have a preconceived notion of an object or ideas, you tend to draw conclusion from this preconceptions and make generalizations that may be erroneous.</span>
