q2. is it possible for the particle undergoing tunneling to be found within the barrier, rather than on either side of it?

The magnitude of the electric field at the position of the third particle is 2.52 x 10⁶ N/C, causing it to remain stationary.

Assuming the third particle has a charge of 0, we can use Coulomb's law to find the magnitude of the electric field at the third particle's position due to the other two charges:

E = k * (q1 / r1² + q2 / r2²)

where k is the Coulomb constant, q1 and q2 are the charges of the first two particles, and r1 and r2 are the distances from the third particle to the first two particles.

Since the triangle is equilateral, the distances from the third particle to the first two particles are both 2.0 cm. Plugging in the values:

E = (8.99 x 10⁻⁹ N*m²/C²) * (4.5 x 10⁻⁹ C / (0.02 m)² + 9.0 x 10⁻⁹ C / (0.02 m)²)

E = 2.52 x 10⁶ N/C

So the magnitude of the electric field at the third particle's position is 2.52 x 10⁶ N/C. Since the third particle has a charge of 0, there is no force on it and it will remain stationary.

The probability that a randomly selected item is failing any of the tests is 0.0857 (approximately).Hence, option C is the correct answer. 0.08567552

Let A1, A2, A3, and A4 be the events that the item fails the first, second, third, and fourth test, respectively.

We need to find the probability that at least one of the events occur.

This is the union of A1, A2, A3, and A4, i.e. we need to find P(A1 U A2 U A3 U A4).

We know that

P(A1 U A2 U A3 U A4) = P(A1) + P(A2) + P(A3) + P(A4) - P(A1 ∩ A2) - P(A1 ∩ A3) - P(A1 ∩ A4) - P(A2 ∩ A3) - P(A2 ∩ A4) - P(A3 ∩ A4) + P(A1 ∩ A2 ∩ A3) + P(A1 ∩ A2 ∩ A4) + P(A1 ∩ A3 ∩ A4) + P(A2 ∩ A3 ∩ A4) - P(A1 ∩ A2 ∩ A3 ∩ A4)

We can use the formula above, however, the intersection of events A1, A2, A3, and A4 are not given.

Therefore, we need to find these probabilities first.

P(A1) = 0.02

P(A2) = 0.03

P(A3) = 0.02

P(A4) = 0.04

P(A1 ∩ A2) = 0.02 x 0.03 = 0.0006, P(A1 ∩ A3) = 0.02 x 0.02 = 0.0004, P(A1 ∩ A4) = 0.02 x 0.04 = 0.0008, P(A2 ∩ A3) = 0.03 x 0.02 = 0.0006 , P(A2 ∩ A4) = 0.03 x 0.04 = 0.0012 ,P(A3 ∩ A4) = 0.02 x 0.04 = 0.0008

P(A1 ∩ A2 ∩ A3) = 0.02 x 0.03 x 0.02 = 0.000012, P(A1 ∩ A2 ∩ A4) = 0.02 x 0.03 x 0.04 = 0.000024, P(A1 ∩ A3 ∩ A4) = 0.02 x 0.02 x 0.04 = 0.000016

P(A2 ∩ A3 ∩ A4) = 0.03 x 0.02 x 0.04 = 0.000024

P(A1 ∩ A2 ∩ A3 ∩ A4) = 0.02 x 0.03 x 0.02 x 0.04 = 0.00000048

Now we can use  P(A1 U A2 U A3 U A4).P(A1 U A2 U A3 U A4) = P(A1) + P(A2) + P(A3) + P(A4) - P(A1 ∩ A2) - P(A1 ∩ A3) - P(A1 ∩ A4) - P(A2 ∩ A3) - P(A2 ∩ A4) - P(A3 ∩ A4) + P(A1 ∩ A2 ∩ A3) + P(A1 ∩ A2 ∩ A4) + P(A1 ∩ A3 ∩ A4) + P(A2 ∩ A3 ∩ A4) - P(A1 ∩ A2 ∩ A3 ∩ A4)

= 0.02 + 0.03 + 0.02 + 0.04 - 0.0006 - 0.0004 - 0.0008 - 0.0006 - 0.0012 - 0.0008 + 0.000012 + 0.000024 + 0.000016 + 0.000024 - 0.00000048= 0.0856

Answer:

definition of matter is that matter takes up space and has mass

Answer:

a)  600 meters

b) between 0 and 10 seconds, and between 30 and 40 seconds.

c) the average of the magnitude of the velocity function is 15 m/s

Explanation:

a) In order to find the magnitude of the car's displacement in 40 seconds,we need to find the area under the curve (integral of the depicted velocity function) between 0 and 40 seconds. Since the area is that of a trapezoid, we can calculate it directly from geometry:

\(Area \,\,Trapezoid=(\left[B+b]\,(H/2)\\displacement= \left[(40-0)+(30-10)\right] \,(20/2)=600\,\,m\)

b) The car is accelerating when the velocity is changing, so we see that the velocity is changing (increasing) between 0 and 10 seconds, and we also see the velocity decreasing between 30 and 40 seconds.

Notice that between 10 and 30 seconds the velocity is constant (doesn't change)  of magnitude 20 m/s, so in this section of the trip there is NO acceleration.

c) To calculate the average of a function that is changing over time, we do it through calculus, using the formula for average of a function:

\(Average\,of\,f(x)=\frac{1}{b-a} \int\limits^b_a {f(x)} \, dx\)

Notice that the limits of integration for our case are 0 and 40 seconds, and that we have already calculated the area under the velocity function (the integral) in step a), so the average velocity becomes:

\(Avearage=\frac{600\,\,m}{40\,\,s}= 15\,\,\frac{m}s}\)

The work done by the applied force on the block against the frictional force is 15.75 J.

Work done is equal to product of force applied and distance moved.

Work = Force x Distance

Given is a 4 kg block is pushed 2m at an acceleration of 0.2 meter per second square up a vertical wall by constant force f applied at an angle of 37 degree with the horizontal if the coefficient of kinetic friction, μ between the block and the wall is 0.30.

From the equilibrium of forces acting on the block, we have

F - f = ma

where, F is applied force, f is frictional force, m is the mass and a is the acceleration.

Frictional force f =  μmgsinθ

Substitute the values, we get

Fcos(37) - μmgsin(37) = ma

Fcos(37) - (0.3)(4)(9.8)sin(37) = 4(0.2)

0.799F - 7.077 = 0.8

F = 9.86 N

Work done by the applied force is

W = Fdcosθ

W = 9.86 x 2 x cos(37)

W = 15.75 J

Thus, the work done by the applied force on the block against the frictional force is 15.75 J.

The acceleration due to gravity on the moon you are visiting is approximately 1.235 m/s².

The acceleration due to gravity, denoted by the symbol "g," is a measure of the gravitational force acting on an object. It is calculated using the formula:

g = F/m

Where F represents the gravitational force and m represents the mass of the object. In this case, the weight of the person on the moon is given as 67.9 N, which is equal to the gravitational force acting on the person. The weight is calculated using the formula:

Weight = mass * g

By rearranging this equation, we can solve for g:

g = Weight / mass

Substituting the given values, with a mass of 55 kg and a weight of 67.9 N:

g = 67.9 N / 55 kg

g ≈ 1.235 m/s²

Therefore, the acceleration due to gravity on the moon you are visiting is approximately 1.235 m/s².

The acceleration due to gravity is a fundamental concept in physics that determines the strength of the gravitational force experienced by objects. It varies depending on the mass and distance between two objects. On Earth, the standard value for acceleration due to gravity is approximately 9.8 m/s². However, on different celestial bodies, such as moons or other planets, the value of g can be significantly different.

The moon you are visiting has a lower mass and smaller radius compared to Earth, which leads to a weaker gravitational force. As a result, the acceleration due to gravity on the moon is lower than on Earth. In this case, the weight of the person is given as 67.9 N, which is the gravitational force acting on them. Dividing this force by their mass of 55 kg gives us the value of g, which is approximately 1.235 m/s².

In order to find the distance at which the engineer should apply brake, we can use 2nd equation of motion. The second equation of motion is as follows:

s = Vi t + (0.5)at²

where,

s = distance from the station = ?

Vi = Initial velocity = 44 m/s

t = time required to stop = 27 s

a = acceleration of train = 2.2 m/s²

Therefore,

s = (44 m/s)(27 s) + (0.5)(2.2 m/s²)(27 s)²

s = 1188 m + 801.9 m

s = 1989.9 m

The velocity of the two objects velocity after colliding is B 1.0 m/s to the right.

To determine the velocity of the two objects after colliding, we need to consider the conservation of momentum. Since the masses of objects X and Y are the same, let's call their mass "m."

Before collision, the momentum of object X is m(5.0 m/s) and the momentum of object Y is m(-3.0 m/s), as it moves to the left. The total initial momentum is m(5.0 m/s) + m(-3.0 m/s) = m(2.0 m/s).

After collision, the objects stick together, so their combined mass is 2m. To find their final velocity, we'll divide the total initial momentum by their combined mass: (m(2.0 m/s))/(2m).

The mass "m" cancels out, and we're left with a final velocity of 1.0 m/s to the right. Therefore, the correct answer is B 1.0 m/s to the right.
