Part D
Now, switch over to the Large Ball Drop Tracker and observe the graphs of vertical displacement against time (y vs. t) and of vertical velocity
against time (vy vs. t) for the large ball, using the same process you did for the small ball. What can you say about the vertical displacement and
velocity of the large ball?

Assuming you are supposed to write each conversion in scientific notation:

(2) 1 m = 100 cm, so

(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m

(3) 1 km = 1,000 m, so

(1.2 km) × (1000 m/km) = 1200 m = 1.2 × 10³ m

(4) 1 m = 1,000 mm = 10³ mm, so

(6.2 × 10 ⁻³ m) × (10³ mm/m) = 6.2 mm

(5) 1 m = 1,000,000,000 nm = 10⁹ nm, so

(4.05 × 10³ nm) × (1/10⁹ m/nm) = 4.05 × 10 ⁻⁶ m

(6) 1 g = 1,000,000 µg = 10⁶ µg, so

(3200 µg) × (1/10⁶ g/µg) = 3200 × 10 ⁻⁶ g = 3.2 × 10 ⁻³ g

Answer:

Kepler's three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. ... (3) The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun.

Recall that vector addition can be visually represented by the head-to-tail method. This means that the head of one vector is glued to the tail of the other vector, to point us directly to the target vector we're after. Think of it like following instructions on a map.

A visual example is shown below. There are two pathways to arrive at the c = a+b vector. The patheway on the right is a+b while the path on the left is b+a. The order doesn't matter since we arrive at the same destination.

-------------------------------------

Here's an algebraic approach without the need of a drawing.

Consider that vectors a and b are defined like so

a = <p,q>

b = <r,s>

where p,q,r,s are real numbers. They define the coordinates of the two vectors.

Adding vectors a and b gets us

a+b = <p,q>+<r,s> = <p+r,q+s>

We add the corresponding coordinates. Since p+r is the same as r+p, we can say,

b+a = <r,s>+<p,q> = <r+p,s+q> = <p+r,s+q> = a+b

Therefore, a+b = b+a. Again, this all relies on the fact that addition of scalar numbers can be done in any order. So by extension, vector addition can be done in any order. This applies to multiple vectors and not just two of them.

Answer:

[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]

Explanation:

We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.

[tex]F= \ m \times a[/tex]

The mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.

[tex]a= \frac{v_f-v_i}{t}[/tex]

The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).

Substitute these values into the formula.

[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]

Solve the numerator.

[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]

Divide.

[tex]a= 2 \ m/s/s[/tex]

[tex]a= 2 \ m/s^2[/tex]

Now we know the mass and acceleration of the wheelbarrow

Substitute the values into the force formula.

[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]

[tex]F= 40 \ kg*m/s^2[/tex]

Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.

[tex]F= 40 \ N[/tex]

Answer:

40 N

Explanation:

We know that

F = ma

and

a = (v - u)/t

So,

F = m(v - u)/t

F = 20(10 - 0)/5

F = 20(10/5)

F = 20(2)

F = 40 N

The  big bang theory or great expansion explains the formation of the universe from a point with very high density where matter and space were created, it can be observed in an experiment

The Big Bang theory that can be adapted with some home experiments, specifically the expansion can be measured using an experiment with inflating balloons.

Materials

deflated balloons

marker

thread

measuring tape

Description of the experiment

The stars or galaxies are marked repeatedly with an initial separation and this distance is measured by a thread the length and the thread with a meter, this is used as measured by the fact that the surface is curved.

The balloon is inflated and measurements of the separation are made, observing that as the volume of the balloon increases (time increase) the separation of the galaxies increases

The increase in distance is explained by the Big Bang theory or great expansion.

There is also astronomical evidence:

* The redshift of the hydrogen spectral lines that is explained by the Dopler effect, which is a move away from objects

* Background radiation in the microwave range that comes from everywhere and would be the residue of a large initial explosion.

Answer:

two protons and two neutrons

it's the answer. hope it helps

Alpha particles have two protons and two neutrons. Therefore, option (D) is correct.

Alpha particles can be defined as positively charged particles released from the decay of several radioactive materials. The mass of the Alpha particle is because of the presence of two protons and two neutrons. Therefore, the Alpha particles nucleus is very similar to the nucleus of the Helium atom and are denoted by the Greek alphabet α.

An alpha particle or ray is also known as doubly ionized helium nuclei (He²⁺). The alpha particle's mass is equal to 6.64 × 10⁻²⁷ Kg. Alpha particles are generally generated during the standard radioactive decay of atomic nuclei.

Alpha particles contains the kinetic energy of 5MeV and a speed of 5 % of that of the speed of light. They are also formed in high-energy particle accelerators and are highly ionized particles with low penetration depth compared to other particles.

For the student that walks to the right 25 m in 15 s and then turns and walks to the left 15 m in 8.0 s, we have:

1. The average speed is 1.74 m.

2. The average velocity is 1.42 m.

1. The average speed is an scalar wich is given by:

[tex] V = \frac{d_{t}}{t_{t}} [/tex]

Where:

[tex]d_{t}[/tex]: is the total distance

[tex]t_{t}[/tex]: is the total time

The total distance and the total time can be calculated as follows:

[tex]d_{t} = d_{1} + d_{2} = 25 m + 15 m = 40 m [/tex]

[tex] t_{t} = t_{1} + t_{2} = 15 s + 8.0 s = 23 s [/tex]

Since V is a scalar, the direction of motion is not important to calculate the final value.

Then, the average speed is:

[tex] V = \frac{d_{t}}{t_{t}} =\frac{40 m}{23 s} = 1.74 m/s [/tex]

2. The average velocity is a vector, so the direction of motion is important here. This ΔV can be calculated with the following equation:

[tex] \Delta V = \frac{\Delta x}{\Delta t} = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} [/tex]

Where:

x: is the displacement  

f: is for final and i: is for initial

Hence, the average velocity is:

[tex] \Delta V = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} = \frac{15 m - 25 m}{8.0 s - 15 s} = 1.42 m/s [/tex]
