Answer:
Explanation:
1. He had the opportunity to have a chance of doing experimental research where he began to develop a theory on electromagnetism. He was then recognized in 1884 and appointed to chair of physics at Cavendish Laboratory. In 1914 there was a new type of physics that lead to more questions than there were answers for and that is when Thomson began associating himself with this new type of physics.
2. Thomson began experimenting with the cathode ray tubes that showed him that all atoms contain small negatively charged particles/electrons. His proposition to the atom was shown with is plum pudding model, which showed negatively charged electrons that were embedded in a positive charge. His discovery came before the discovery of the atomic nucleus that would be included in the electron in the atomic model.
3.His contributions to the atomic model include that all matter is made of atoms, atoms are invisible and indestructible, all atoms in a certain element are identical, two or more atoms that are combined form a compound, and a chemical reaction is the rearrangement of the atoms. His ideas of the atomic model that do not exist in the modern day atomic model include the fact that the distribution of the negative and positive particles was not uniform.

They rely on albedo (it’s the fraction of solar energy, which is short-wave, that’s reflected from the Earth back into space, it’s how ‘reflective’ the Earth’s surface is) to reflect a lot because if it doesn't the ice caps will melt and polar bears will lose their home
The magnitude of v⃗ is {sqrt(m1v1)2+(m2v2)2/ m1+m2}, that is, the speed v of the two-car unit after the collision.
<h3>What is
collision?</h3>
- In physics, collisions occur when particles, aggregates of particles, or solids come close to each other, interact and affect each other.
- Collisions are of three types Fully elastic collision, inelastic collision and Perfectly inelastic collision.
- Multiply the mass of the second object by its velocity.
- For example, if the weight is 1,000 and the speed is -30 meters per second, then its momentum is 30,000 kg meters per second.
- Add the two velocities together to determine the direction the object will move after a collision.
- So the formula for determining the size of a vector (in 2D space) is v = (x, y).|v| = √(x2 + y2).
- This formula is derived from the Pythagorean theorem.
- The formula V = (x, y, z) that determines the size of a vector (in 3-dimensional space) is:|V| = √(x2 + y2 + z2)

Answer: 4 over 3
Explanation:
well x^3=64/27
take cube roots for both sides
x= 3√64/27
Use property of radical expressions and you’ll have the answer.
x=4/3
Answer:
1 km = 1000 m
1 m = 100 cm
1 m = 1000 mm
1 cm = 10 mm
hope this helps u figure it out :)
