How do solutions differ from other mixtures?

Problem: A barbell consists of two small balls, each with mass m at the ends of a very low mass rod of length d. The barbell is

zepelin [54]

Answer:

mass of ball 1=m1

mass of ball 2=m2

velocity of ball=r1w1

velocity of ball 2=r2w2

Total angular momentum=m1*v1+m2*v2

but

v1=r1*w1

v2=r2*w2

Substitute values in above equation

Total angular momentum of the system=m1*r1*w1+m2*r2*w2

1. You get hit with a force of 45 N by a ball with a mass of 0.75 kg. How fast was the

dlinn [17]

Answer:

$60 {ms}^{ - 2}$

Explanation:

As we know,

=》Force = Mass × Acceleration

=》45 N = 0.75 × Acceleration

=》Acceleration = 45 ÷ 0.75

=》Acceleration = 60

hence, the Acceleration of the ball would be. 60 meters per second square

$60m {s}^{ - 2}$

The charged particles in the beams that Thomson studied came from atoms. As these particles moved away from their original atoms

aalyn [17]

The question to the above information is;

What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?

Answer;

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.

Explanation;

-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.

J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:

atoms are spheres of positive charge
electrons are dotted around inside

(99 POINTS) While driving her new Camaro at 20.0 m/s down a four-lane highway, Jessica comes up behind a slow-moving dump truck

Ede4ka [16]

Answer:

To go from 20.0 to 30.0 m/s, that is a velocity change of 10.0 m/s.

From the definition of acceleration,

a = (velocity change)/(time required)

In this case you know that a = 5.0 m/s^2, so

time = (10.0 m/s)/(5.0 m/s^2)

= 2.0 seconds
