Answer: a system

Explanation: just did the test

Answer:

system is correct

Explanation:

Since the car is accelerating at a constant rate, the distance it travels during each second of its motion will be directly proportional to the time it has been accelerating.

In the first second, the car moved a distance of 2 meters, and in the second second, it will move twice the distance of the first second, so the car will move additional distance of 2*2 = 4 meters during the second second of its motion.

The distance traveled during the second second of its motion is 1/2 * 2 = 1 meters.

A car that accelerates at a constant rate will move a distance equal to the initial velocity multiplied by time plus 1/2 the acceleration multiplied by the square of time. Since the car starts from rest, the initial velocity is zero.

Therefore, the distance traveled during the second second is 1/2 * acceleration \(* (time)^2 = 1/2 * a * t^2 = 1/2 * a * 1^2 = 1/2 * a\) Since the car moved 2.0 meters in the first second, it means the acceleration is\(2m/s^2\), and the distance traveled during the second second is 1/2 * 2 = 1 meters.

To find the tensions T1 and T2 in the shoestrings, we use the component method and set up equations for the x- and y-components of the forces. By assuming that T1 and T2 have the same magnitude, we can solve for T and find that T1 and T2 are both approximately 8.66 lbs. To verify this, with weights representing the forces and confirm that the table balances.

Let T1 and T2 be the tensions in the shoestrings. Since the person pushes downward at an angle of 60 degrees to the right with a force of 20 lbs, we can represent this force as a vector F with components

Fx = 20 cos(60) = 10 lbs

Fy = -20 sin(60) = -17.32 lbs (negative because it points downwards)

The tensions in the shoestrings can be represented by vectors T1 and T2. Since the shoestrings are tied to the shoes, the tensions must be perpendicular to the shoes. Therefore, we can represent T1 and T2 as follows

T1x = T1 cos(90) = 0

T1y = T1 sin(90) = T1

T2x = T2 cos(90) = 0

T2y = T2 sin(90) = T2

Using the component method, we can add the x-components and y-components of the forces to get

ΣFx = T1x + T2x + Fx = 0 + 0 + 10 = 10 lbs

ΣFy = T1y + T2y + Fy = T1 + T2 - 17.32 = 0

Since the shoestrings are tied together at the shoes, we know that T1 and T2 have the same magnitude

T1 = T2 = T

Substituting this into the second equation, we get

T + T - 17.32 = 0

Solving for T, we get

T = 8.66 lbs

Therefore, the tensions in the shoestrings are both approximately 8.66 lbs.

To verify this, we can set up the forces on the table to match the forces acting on the shoestrings. We can use a weight of 20 units to represent the force applied by the person, and two weights of 8.66 units each to represent the tensions in the shoestrings.

We can arrange the weights so that one tension weight is at an angle of 60 degrees to the right and the other is at an angle of 30 degrees to the left. If the forces are in equilibrium, the force table should balance. By adjusting the weights, we can confirm that the force table does indeed balance, verifying our calculated tensions.

When a cyclist bikes with an average velocity of 20 m/s for 5 seconds, the magnitude of the cyclist displacement would be 1×10² meters.

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object. The unit of velocity is meter/second. It can also be represented by the infinitesimal rate of change of displacement with respect to time. The generally considered unit for velocity is a meter per second.

The mathematical expression for velocity is given by the formula

velocity= total displacement/Total time

The area under the velocity-time graph represents the total displacement covered by the object while the slope of the velocity time graph represents the acceleration of the object.

For the given problem when a cyclist bikes with an average velocity of 20 m/s for 5 seconds,

Displacement =velocity×time

                       =20×5

                       =1×10²

Answer: The depth of the ocean is 650 feets at the bottom of the sunlight zone.

The distance travelled by echo sound is given by the formula -

Speed = 2×distance/time

So, calculating the speed of sound from the formula using distance and time

Speed = 2×25/(1/100)

Speed = 50×1000

Speed of sound = 5000 feet/second

Now, calculating the distance or depth of ocean at the bottom of the sunlight zone -

Distance = (speed×time)/2

Distance = (5000×26/100)/2

Distance = 1300/2

Distance = 650 feets

Hence, the depth of ocean is 650 feets.

brainly.com/question/19579065

Answer:

We can start by using the formula:

distance = speed x time

where distance is twice the depth of the ocean at the bottom of the Sunlight Zone (since the pulse travels down to the seafloor and then back up), speed is the speed of sound in water, and time is the round-trip time of the pulse.

The speed of sound in water is approximately 1,500 meters per second (or 4,921 feet per second).

Converting the round-trip time to seconds, we have:

26 seconds - 1 second = 25 seconds

Substituting the values into the formula:

2 x depth = 4,921 feet/second x 25 seconds

2 x depth = 123,025 feet

depth = 61,512.5 feet

Therefore, the ocean at the bottom of the Sunlight Zone is about 61,512.5 feet deep.

Now, according Newton's first law of motion, an object will continue in it's present state of rest except it is acted upon by an external body.

Explanation:

The energy applied by the voltage must be equal to the energy associated with the wavelength of light:

\(eV = \frac{hc}{\lambda}\\\)

where,

e = charge on electron = 1.6 x 10⁻¹⁹ C

V = stopping potential

h = Planck's Constant = ?

c = speed of light = 3 x 10⁸ m/s

λ = wavelength of light

For λ = 400 nm = 4 x 10⁻⁷ m, V = 0.7 V:

\((1.6\ x\ 10^{-19}\ C)(0.7\ V) = \frac{h(3\ x\ 10^8\ m/s)}{4\ x\ 10^{-7}\ m}\\\)

h = 1.49 x 10⁻³⁴ J.s

For λ = 500 nm = 5 x 10⁻⁷ m, V = 0.2 V:

\((1.6\ x\ 10^{-19}\ C)(0.2\ V) = \frac{h(3\ x\ 10^8\ m/s)}{5\ x\ 10^{-7}\ m}\\\)

h = 0.53 x 10⁻³⁴ J.s

Taking average of both values:

\(h = \frac{(0.53+1.49)\ x\ 10^{-19}\ J.s}{2}\)

h = 1.01 x 10⁻³⁴ J.s

To increase a car's acceleration, the engineers should consider decreasing the car's mass and/or increasing the force that the engine provides. Therefore, options A and D are the correct answers.

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass. This means that a smaller mass or a larger force will result in a greater acceleration. Therefore, reducing the mass of the car will require less force to achieve the same acceleration, or the same force will result in a greater acceleration.

To decrease the mass of the car, the engineers could consider using lighter materials for the car's body and frame or removing unnecessary components. On the other hand, to increase the force that the engine provides, the engineers could consider upgrading the engine or increasing the fuel intake.

Option B, which suggests decreasing the force that the engine provides, would have the opposite effect and result in a slower acceleration. Option C, which suggests increasing the mass of the car, would also have the opposite effect and require more force to achieve the same acceleration.

Option E, which suggests increasing the top velocity the car can travel, is not directly related to acceleration. Top velocity refers to the maximum speed that a car can reach, whereas acceleration refers to the rate of change of velocity. While increasing the car's top velocity may indirectly affect acceleration, it is not a direct solution to increasing acceleration.
