Protons are made up of ___ up quark(s) and ___ down quark(s).a. 1, 1
b. 1, 2
c. 2, 1
d. 2, 2

Answers

Answer 1
Answer:

The correct answer is C. 2, 1

Explanation:

In physics, protons along with neutrons and electrons are the particles that compose atoms which are the basic unit of matter. Protons different neutron have a positive charge and along with neutrons create the nucleus of the atoms. In terms of composition, protons are made up of three quarks (elementary particles) that are divided into two up quarks and one down quark that are two types of quarks with low mass. According to this, it can be concluded protons are made up fo 2 up quarks and 1 down quark.

You're taking your first dive in ALVIN (Fig 10.13) to witness a hot spot on the ocean floor. As you descend and arrive on site, what are your first impressions?

Answers

Answer:

Explanation:

The experience is magnanimous and wonderful when witnessing the hotspot site. It was a great feeling! I could witness the red hot lava oozing out to the ocean floor from the subsurface like water from a hot-spring, and immediately, a cooling effect occurs. At that current time, the gas was coming up in the form of gas bubbles. I believed there was a mini-volcano located inside the ocean! The scene was fascinating, just like inserting a red-hot metallic-iron ball into the cool water, thereby creating a fizzing of gas and the ball's immediate cooling. It was a remarkable experience of witnessing an underwater volcano with the erupting lava and its immediate cooling to form a solid material.

Suppose that now you want to make a scale model of the solar system using the same ball bearing to represent the sun. How far from it would you place a sphere representing the earth? (Center to center distance please.) The distance from the center of the sun to the center of the earth is 1.496×10111.496×1011 m and the radius of the sun is 6.96×1086.96×108 m.

Answers

In this exercise we have to use the knowledge in distance, in this way we will find that the proportional distance found is:

d = 0.645 m

So from the information given in the text we find that:

  • The distance from the center of the sun to the center of the earth is 1.496*10^(11) \ m
  • The radius of the sun is 6.96*10^(8)m
  • We need to assume a radius for the ball bearing, so suppose that the radius is 3 mm  

First, we need to find in what way or manner often the radius of the brightest star exist considerable respect to the range of the ball significance, that exist given apiece following equating:

(r_a)/(r_b)= \frac{6.96*10^8}{3*10{-3}} =2.32*10^(11)

Now, we can calculate the distance from the center of the sun to the center of the sphere representing the earth:  

d_(s) = (d_(e))/(r_(s)/r_(b)) = (1.496 \cdot 10^(11) m)/(2.32\cdot 10^(11)) = 0.645 m

See more about distance at brainly.com/question/989117

Answer:

d = 0.645 m(assuming a radius of the ball bearing of 3 mm)

Explanation:

The given information is:

  • The distance from the center of the sun to the center of the earth is 1.496x10¹¹m = d_(e)
  • The radius of the sun is 6.96x10⁸m = r_(s)

We need to assume a radius for the ball bearing, so suppose that the radius is 3 mm = r_(b).  

First, we need to find how many times the radius of the sun is bigger respect to the radius of the ball bearing, which is given by the following equation:

(r_(s))/(r_(b)) = (6.96\cdot 10^(8)m)/(3\cdot 10^(-3)m) = 2.32\cdot 10^(11)

Now, we can calculate the distance from the center of the sun to the center of the sphere representing the earth, d_(s):  

[tex] d_{s} = \frac{d_{e}}{r_{s}/r_{b}} = \frac{1.496 \cdot 10^{11} m}{2.32\cdot 10^{11}} = 0.645 m

Two asteroids bump in space. The larger one has a mass of 3000 kg and the smaller one has a mass of 100 kg. If the force of the collision is 10,000 newtons on each asteroid, what are their accelerations?a. The larger one is unaffected by the collision, while the smaller one accelerates at 100 m/s2.
b. The larger one accelerates at 3.33 m/s2, while the smaller one accelerates at 100 m/s2.
c. The larger one accelerates at 100 m/s2, while the smaller one accelerates at 3.33 m/s2.
d. The ...

Answers

Answer:

B) The larger one accelerates at 3.33 m/s² while the smaller one accelerates at 100 m/s².

Explanation:

Parameters given:

Mass of larger asteroid = 3000 kg

Mass of smaller asteroid = 100 kg

Force of collision = 10000 N

Since both of them experience the collision force, we can find how that force causes them to accelerate by using the formula of force:

F = m*a

=> a = F/m

For the larger one,

a = 10000/3000 = 3.33 m/s²

For the smaller one,

a = 10000/100 = 100 m/s²
 There's really no such thing as the force of a collision.

F = M A
A = F / M

If a 10,000N net force acts on a 3,000 kg object, then the object's
acceleration is (10,000N / 3,000kg) = 3-1/3 m/s² for as long as the
force on it persists, and zero after that.

If a 10,000N net force acts on a 100 kg object, then the object's
acceleration is (10,000N / 100kg) = 100 m/s² for as long as the
force on it persists, and zero after that.

Those appear to be the numbers in choice-b, but the description
of the event and the situation is misleading.

Imagine two billiard balls on a pool table. Ball A has a mass of 2 kilograms and ball B has a mass of 3 kilograms.
