The charge will move to the left.

The electric potential varies linearly with x, so we can find the equation for the potential as:

V(x) = mx + b,

where m is the slope and b is the y-intercept. We can use the given points to solve for m and b:

300 V = m(0 cm) + b

-100 V = m(5 cm) + b

Subtracting the first equation from the second, we get:

-400 V = 5m

m = -80 V/cm

Substituting this value for m into one of the equations, we get:

300 V = -80 V/cm * (0 cm) + b

b = 300 V

So the equation for the potential is:

V(x) = -80 V/cm * x + 300 V

Now we can use the electric field to determine the direction of the force on the positive charge. The electric field is the negative gradient of the potential:

E(x) = -dV/dx = 80 V/cm

At x = 2.5 cm, the electric field is:

E(2.5 cm) = 80 V/cm

Since the charge is positive, it will experience a force in the direction of the electric field, which is to the left. Therefore, the charge will move to the left.

The answer is (b) Move to the left.

Explanation:

The minimum force (Fmin) required to move the block up the ramp is 12.7 N.

Mass of the block (m) = 3.3 kg

Angle of the ramp (θ) = 37°

Coefficient of friction between the block and the ramp (μg) = 0.44

Coefficient of kinetic friction between the block and the ramp (uk) = 0.30

Step 1: Resolve the forces acting on the block.

The weight of the block (mg) can be resolved into two components:

- The force acting parallel to the incline (mg*sinθ)

- The force acting perpendicular to the incline (mg*cosθ)

Step 2: Calculate the force of friction.

The force of friction can be calculated using the equation:

Force of friction (Ff) = μg * (mg*cosθ)

Step 3: Determine the minimum force required.

To move the block up the ramp, the applied force (Fapplied) must overcome the force of friction.

Thus, the minimum force required (Fmin) is given by:

Fmin = Ff + Fapplied

Step 4: Substitute the given values and calculate.

Ff = μg * (mg*cosθ)

Fmin = Ff + Fapplied

Now, let's calculate the values:

Ff = 0.44 * (3.3 kg * 9.8 m/s² * cos(37°))

Ff ≈ 12.717 N

Fmin = 12.717 N + Fapplied

Therefore, the minimum force (Fmin) required to move the block up the ramp is approximately 12.7 N.

Rachel is correct because she said that is body receive equal magnitude of impulse which completely satisfy the law of conservation of linear momentum.

According to law Conservation of Linear Momentum, if there is no external force working on the system, then the linear momentum remains conserved before and after the collision.

We know that,

Momentum is nothing but the product of force and the time taken for the contact period of the colliding bodies.

We assume that during the head on collision of the body, the body is remain in contact for such a short period of time that there is no external force all the impulse created due to the external force is neglected.

So, because the impulse imparted on both the bodies are equal to each other.

It would take 1.556 seconds for the barrier to crumple and safely slow down the person with a force of 1180 N.

To calculate the time required to crumple the barrier and safely slow down the person, we can use the concept of impulse.

The impulse, denoted by J, is defined as the product of force and time, and it represents the change in momentum of an object. In this case, the impulse required to safely slow down the person can be calculated using the maximum force and the person's initial momentum.

The momentum of a person is given by the product of their mass and velocity:

Momentum = mass × velocity

Given that the person's mass is 68 kg and their velocity is 27 m/s, the initial momentum is:

Initial momentum = 68 kg × 27 m/s

To safely slow down the person, the impulse provided by the barrier should be equal to the change in momentum.

Therefore, we have:

Impulse provided by barrier = Final momentum - Initial momentum

Since the person is brought to rest, the final momentum is zero. Thus, we have:

Impulse provided by barrier = -Initial momentum

Now we can express the impulse in terms of force and time:

Impulse provided by barrier = Force × Time

Plugging in the known values, we can solve for time:

-Initial momentum = Force × Time

68 kg × 27 m/s = 1180 N × Time

Simplifying the equation, we find:

Time = (68 kg × 27 m/s) / 1180 N

Evaluating the expression:

Time = 1836 kg·m/s / 1180 N

Finally, converting kg·m/s to seconds, we get:

Time ≈ 1.5559 seconds

Therefore, it would take approximately 1.556 seconds for the barrier to crumple and safely slow down the person with a force of 1180 N.

Answer:

Answer: D. 1.4 meters/second

Explanation:

To calculate average Velocity, the proportion of the total Displacement or distance traveled to the total time taken during that Displacement is calculated.

Total Displacement from rest(that is 0) to 15 seconds (21, on the graph)

(0, 21)

Total time taken = 15 seconds

Average Velocity = (total Displacement / total time taken)

Average Velocity = (21 - 0) / (15 - 0)

Average Velocity = 21 / 15

Average Velocity = 1.4 meters per second

Main answer:

The separation between the slits on the diffraction grating is 0.001 cm.

Supporting answer:

The diffraction grating has 1000 lines per cm, which means that there are 1000 slits per cm. The separation between adjacent slits is therefore:

d = 1 cm / 1000 = 0.001 cm

We can use the grating equation to determine the angles at which the light diffracts:

d(sin θ) = mλ

where d is the slit separation, θ is the diffraction angle, m is the order of the diffraction maximum, and λ is the wavelength of the light.

We can rearrange this equation to solve for the diffraction angle:

sin θ = mλ/d

For the first-order maximum, m = 1. Plugging in the given values, we get:

sin θ = (1)(600 nm)/(0.001 cm) = 0.6

Taking the inverse sine of both sides, we get:

θ = sin^(-1)(0.6) = 36.9°

Now that we know the diffraction angle, we can use trigonometry to find the distance between adjacent diffraction maxima on the screen. The distance between adjacent maxima is given by:

y = l*tan(θ)

where y is the distance between adjacent maxima on the screen, and l is the distance between the grating and the screen.

Plugging in the given values, we get:

y = 2 m * tan(36.9°) = 2.6 m

Therefore, the distance between adjacent maxima on the screen is 2.6 m.
