Answer:
0 111.0N be cause the rest do not add up
Answer: The last part of the question has some details missing which is ; (Assume that the molecule's velocity is perpendicular to the two sides that it strikes.) molecule v=482 m/s molecule momentum=2.56 x 10^(-23)
Explanation:
- The momentum of the molecule is 2.56 x 10^(-23) .
- Particle hits the wall and bounces.
- Momentum is reversed. Change in momentum = impulse
- This is Force x time.
- Momentum change happens at a wall after each trip.
- time required = distance /speed
- Average force = impulse / time
- = 2 x 482 x 2.56 x 10^(-23) / (0.17 x 2)
- = 7.76 x 10^20N, is the average force the molecule exerts on one of the walls of the container.
Answer:
Lacks colored blood - Scorpion
Soft, unsegmented body - Octopus
A vertebrate - Bird
Lacks antennae - Starfish
Explanation:
Scorpion belongs to the Phylum Arthropoda of the Kingdom Animalia. All the organisms of this phylum lack coloured blood.
Octopus comes under the Phylum Molusca of the Kingdom Animalia. Soft, unsegmented body is the property of the organisms of this phylum.
Bird belongs to the Vertebrata class of the Phylum Chordata of Kingdom Animalia.
Starfish belongs to Echinodermata Phylum of the Kingdom Animalia. The organisms of this category do not posses antennae.
The atomic number tells you the number of protons in an atom. This value never changes because the number of protons in the nucleus always remains constant. The mass number tells you the number of protons and neutrons (or nucleons) together: protons + neutrons = mass number. Since the number of neutrons in the nucleus varies, you can have different amounts of neutrons in the same type of atom. These varied types are called isotopes.
Hope this helps.
Answer:
option C
Explanation:
The correct answer is option C
When the driver takes the sharp right turn the door will exert rightward pressure on the driver.
When the driver takes the sudden right turn the tendency of the body is to be in the straight line by the vehicle moves in the circular path so, as the vehicle turns it applies a rightward force on you.
The pushing of the door to you because of the centripetal force acting on the car due to sudden sharp turn.
