Most likely solid. Molecules move in a chaotic matter, which a Scottish botanist found out in the 19th century. In gases, this chaotic movement is the most “dramatic” and they move around freely; in liquids it’s a bit less noticeable, and in solids the particles oscillate around locked positions. Movement in plasma is similar to gas.
Friction is a force that oppose other forces and can slow them down
Answer:
SUNLIGHT OR SUNRAYS OR ENERGY OR HEAT
Explanation:
I'm not sure tbh, but if it helps, heres a game that helped me understand bases acids and neutrals for chem in 8th grade! http://static.lawrencehallofscience.org/scienceview/scienceview.berkeley.edu/html/showcase/flash/jui... I know it looks cheesy, but it helps! Chem is something youll have until college, and it helps to learn about it. You can make drinks using acids, bases, and neutrals!
The acceleration of the train at the give initial and final velocity is determined as 10.5 m/s².
<h3>Acceleration of the train</h3>
The acceleration of the train is calculated as follows;
a = Δv/t
where;
- u is initial velocity = 162 km/hr = 45 m/s
- v is final velocity of the car = 540 km/hr = 150 m/s
a = (150 - 45)/10
a = 10.5 m/s²
Thus, the acceleration of the train at the give initial and final velocity is determined as 10.5 m/s².
