Answers

Answer:

m = 4 At Mass units = 4 * 1.66E-27 kg = 6.64E-27 kg  mass of particle

q = 2 * 1.60E-19 C = 3.2E-19 C     total charge of alpha particle

T = 8.8E-8 s     period of 1 revolution

F = q V B      magnetic force

F = m V^2/ R     centripetal acceleration

q V B = m V^2 / R

B = m V / (q * R)

T = 2 pi R / V     time for 1 revolution

R = V T / (2 pi)

B = (m V / q) * 2 pi / (V T) = 2 pi m / (q T)

If you throw a ball up into the air and it reaches its original height after 6 seconds, calculate how high above its original position the ball reached. (Answer to two decimal places).

Answers

Explanation:

Assuming that there is no air resistance, the given time means that the ball reached its maximum height 3 seconds after throwing it upwards so we can solve its

maximum height by solving for [tex]v_{0y}[/tex] first:

[tex]v_y = v_{0y} - gt \Rightarrow v_{0y} = gt[/tex]

[tex]v_{0y} = (9.8\:\text{m/s}^2)(3\:\text{s}) = 29.4\:\text{m/s}[/tex]

Now that we know [tex]v_{0y},[/tex] we can now solve for [tex]y_{max}:[/tex]

A 5000 kg train is traveling at a velocity of 100 m/s and hits another train. The two trains stick together and the new velocity is 50m/s. What is the mass of the second train?

Answers

Answer:

Explanation:

Conservation of momentum is used to solve

Unfortunately we have a missing piece of information such as the initial velocity of the unknown mass train.

If we ASSUME that the second train is at rest

5000(100) + m(0) = 5000(50) + m(50)

which means m = 5000 kg

However, I'll show you the importance of knowing that initial velocity by finding it assuming the other answers are valid

if m = 15000 kg

5000(100) + 15000(v₀) = (5000 + 15000)(50)

v₀ = 33 ⅓ m/s

if m = 10000 kg

5000(100) + 10000(v₀) = (5000 + 10000)(50)

v₀ = 25 m/s

if m = 8000 kg

5000(100) + 8000(v₀) = (5000 + 8000)(50)

v₀ = 18.75 m/s

So you can see why I had to assume an initial velocity. Any of the masses could work if the initial velocity is chosen correctly.

An airplane travels 250 km due east, then turns and travels 180 km [E 60°S]. Determine the resulting travel displacement for this plane.​

Answers

Answer:

388.56km[E13degS]

Explanation:

Δdx = Δd1x + Δd2x

Δdx = 250km [E]+ 180sin(60) [E]

Δdx = 405.88 km [E]

Δdy = Δd1y + Δd2y

Δdy = 0 + 160cos(60) [S]

Δdy = 90km [S]

Δdt = √(Δdx)^2+(Δdy)^2

Δdt = √164738.57+8100

Δdt = 398.85km

tanθ = Δdy/Δdx

tanθ = 90/388.56

θ = tan-1(90/388.56)

θ = 13.04 deg

What is the tension in the string?
(I’m really having a hard time understanding this topic, and my professor isn’t helping much, so any extra explanation are greatly appreciated). The angles are 54.9205°.

Answers

If you look at the sketch I drew for the earlier part of this question, you'll see that, with respect to the positive horizontal (i.e. directly to the right), T₁ makes an angle of 180° - 54.9205° ≈ 125°, while T₂ makes an angle of 54.9205° ≈ 55°.

Split up the force acting on the block into vertical and horizontal components. We have

• net vertical force

F = T₁ sin(125°) + T₂ sin(55°) - mg = 0

where m = 0.56 kg, and

• net horizontal force

F = T₁ cos(125°) + T₂ cos(55°) = 0

Both net forces are 0 because the block is suspended in equilibrium.

Notice that cos(125°) = -cos(55°), so the second equation tells you that T₁ = T₂ and that the tensions in either string are the same. Also, sin(125°) = sin(55°).

Then in the first equation, we have

T₁ sin(125°) + T₂ sin(55°) - mg = 0

2 T₁ sin(55°) = mg

T₁ = mg/(2 sin(55°))

T₁ = (0.56 kg) (9.8 m/s²)/(2 sin(55°))

T₁ ≈ 3.35 N

Calculate the acceleration of the object as it slides down the incline plane.

Answers

Answer:

0.788 m/s²

Explanation:

Ff = 0.1 × 5 kg × 10 m/s² × cos 38°

Ff = 5 N × 0.788

Ff = 3.94 N

F = m × a

3.94 N = 5 kg × a

a = 3.94 N / 5 kg

a = 0.788 m/s²

A350kg car is moving 16m/s north and collides with a 650kg truck going 11m/s east.if it lock bumpers,how fast and in what direction will they are going after the collision

Answers

Hi there!

We can begin by breaking the problem up into two directions, horizontal and vertical.

The collision is perfectly inelastic since the two objects stick, so:

1 = car

2 = truck

Momentum in the east direction (positive and horizontal, car NOT going in this direction has a velocity of 0 m/s):

m2v2 = (m1 + m2)v

(650 · 11) / (350 + 650) = 7.15 m/s

Momentum in the north directions (only initial is the northward velocity of the car):

m1v1 = (m1 + m2)v

(350 · 16)/(350 + 650) = 5.6 m/s

Find the overall velocity using the pythagorean theorem:

√(5.6²) + (7.15²) = 9.08 m/s

Find the direction using trigonometry. Use tangent in this situation:

tan Ф = O/A

tan⁻¹(5.6/7.15) = 38° north of east

Explanation:

For these types of questions, you should draw out your triangles and resultant vectors.

For this, we can use the pythagorean theorem to solve this :

     vpf^2 = vpi^2 + vw^2

     vpf^2 = 45^2 + 191^2

     vpf = [tex]\sqrt{38507[/tex]

     vpf = 196.2294

     vpf = 200 mph

Now we need to find the angle of the plane's direction using soh cah toa

     Tan(x) = O / A

              x = tan^-1(191/45)

              x = 76.74

              x = 77 degrees

 

Therefore, the plane's result velocity is 200 mph [ E 77 N ]

C: What is the change in its velocity during this 1-s interval?

D: What is its velocity 1 s after it reaches its highest point ?

E: What is the change in velocity during this 1 s interval?

F: What is the change in velocity during the two second interval?

G: what is the acceleration of the ball during any of these time intervals and the moment the ball has zero velocity?

Answers

Answer:

In the free fall motion we have that the acceleration is constant and produced by gravity, this acceleration has a magnitude of 32 ft/s2 or 9.8 m/s2 depending on the units you are working with. This means that every second the speed changes a magnitude of 32 ft/2, the velocity will depend of whether the ball is going upward (positive) or downward (negative).

A) At the highest point the ball stops to start the descend, here v=0 ft/s

B) +32 ft/s. The vector is going up, in the next second the velocity is going to be 0 (negative acceleration)

C) V=vf-vo=0-32=-32 ft/s is the constant change in velocity in projectile motion

D) -32 ft/s. The vector is pointing downward

E) V=vf-vo=-32-0=-32 ft/s is the constant change in velocity in projectile motion, 32 ft/s per second

F) Delta V=vf-vo=-32-32=-72 ft/s

g) gravity acceleration is constant 32 ft/s2 (pointing downward vector)

What do you mean by an Atom?

An atom may be defined as a particle of matter that uniquely defines a chemical element. Each and every atom consists of a central nucleus that holds positively charged subatomic particles known as Protons along with neutrons.

Apart from protons and neutrons, the negatively charged subatomic particles known as electrons are always revolved around the nucleus of each atom in its orbitals.

According to the context of this question, an atom is the smallest unit of matter which significantly retain all the chemical properties of an element. Thus, the second option is eliminated. They are naturally present not made in stars. So, the option third is also eliminated.
