Explanation:

Two people push on a shopping cart from opposite sides. Situation will the motion of the shopping cart stay the same, the correct option is (D) The two people push with a balanced face.

In this situation, the net force on the shopping cart will be zero, since the two forces are equal in magnitude and opposite in direction. If the forces are balanced, the shopping cart will not accelerate and will stay in the same state of motion (at rest or moving at a constant velocity). In scenario A and C, the forces are not balanced and therefore will cause acceleration.

So the net force acting on the tanker is: F_net = sqrt(Fx^2 + Fy^2) = 2.4 x 10^4 N And the acceleration of the tanker is: a = F_net / m = 2.4 x 10^4 N / 3.3 x 10^7 kg = 7.27 x 10^-4 m/s^2.

How to calculate net force and acceleration?

To find the acceleration of the tanker using vector methods, we can use the following equation:

F_net = ma

where F_net is the net force acting on the tanker, m is the mass of the tanker, and a is the acceleration of the tanker.

In this case, the two tugboats are pulling in opposite directions, so we need to find the vector sum of their forces to find the net force acting on the tanker.

Using the component method, we can find that the x-component of the net force is:

Fx = 2.4 x 10^4 N * cos(16) - 2.4 x 10^4 N * cos(9) = -2.4 x 10^4 N

and the y-component of the net force is:

Fy = 2.4 x 10^4 N * sin(16) + 2.4 x 10^4 N * sin(9) = 0 N

So the net force acting on the tanker is:

F_net = sqrt(Fx^2 + Fy^2) = 2.4 x 10^4 N

And the acceleration of the tanker is:

a = F_net / m = 2.4 x 10^4 N / 3.3 x 10^7 kg = 7.27 x 10^-4 m/s^2

The first surviving term in the distant field in this situation might be referred to as a quadrupolar field.

The determination that the first surviving term in the distant field is a quadrupolar field is based on the fact that the net charge and the visible dipoles in the arrangement cancel out, leaving no monopolar or dipolar fields.

A quadrupole is a distribution of charges in which there are two positive and two negative charges of equal magnitude and opposite sign, arranged symmetrically about a central point.

A quadrupole generates a quadrupolar field, which falls off as the inverse cube of the distance from the source, as opposed to the inverse square of the distance for a dipole.

So when a net charge and dipoles are cancelled, the next term that could survive is the quadrupolar term.

The magnitude of the electric force on the electron is 2360 N and it points due east.

Electric force is an attractive or repulsive force between two particles that have an electric charge. This force is generated when two charged particles interact due to their charges. The strength of the electric force depends on how much charge each particle has, as well as their distance from each other. Electric forces are responsible for phenomena such as static electricity and lightning, and they can also be used to power electric motors and other devices.

This is because an electric field exerts a force on a charged particle in the direction that is opposite to the direction of the field. Since the electric field points due east, then the force on the electron will point due west.

The minimum time required to travel 1.0 km is 8.75 seconds.

Travel is the movement of people from one place to another, usually over a certain distance and for a certain period of time. It can be done for many reasons, including pleasure, business, or to visit family or friends.

This can be calculated by taking the total distance traveled (1.0 km) and dividing it by the average speed (100 km/h). The average speed is 100 km/h because the car accelerates uniformly from 0 km/h to 100 km/h in 3.5 seconds.
Therefore, the total time required is 10 seconds (1 km / 100 km/h). However, this does not take into account the deceleration time of the car, which must also be taken into account.
The maximum braking rate of the car is 0.7 g, which is equivalent to 7 m/s2. Since the car must come to a complete stop at the end of the 1.0 km journey, the time required for deceleration must be calculated. This can be done using the equation:
Time for deceleration = (Final Velocity - Initial Velocity) / Acceleration
Since the initial velocity is 0 m/s and the final velocity is 0 m/s, the equation simplifies to:
Time for deceleration = 0 / 7 m/s2 = 0 seconds
Therefore, the total time required to travel 1.0 km is 10 seconds (for acceleration) + 0 seconds (for deceleration) = 10 seconds. Subtracting this from the total time required gives us the minimum time required to travel 1.0 km, which is 8.75 seconds.

The direction of the force on the charge at the origin is towards the charge at (0.53, 0.41) m, since the charges have opposite signs and attract each other.

The direction of the force exerted on a point charge at the origin by a second point charge can be found using Coulomb's law, which states that the force between two point charges is proportional to the product of their charges and inversely proportional to the square of the distance between them. The formula for the force is:

F = k * q1 * q2 / r^2

where k is the Coulomb constant (8.99 x 10^9 N * m^2 / C^2), q1 and

q2 are the charges, and

r is the distance between the charges.

To find the direction, we must first find the components of the force along the x and y axes.

Then, we can use arctan to find the angle relative to the positive x direction.

The distance between the charges can be found using the Pythagorean theorem:

[tex]r = \sqrt{((0.53 m)^2 + (0.41 m)^2)[/tex] = 0.65 m

The x and y components of the force can then be found using the formula:

Fx = F * cos(θ) = k * q1 * q2 * x / r^3

Fy = F * sin(θ) = k * q1 * q2 * y / r^3

The body will be at a temperature of 60°F after around 72 minutes.

The problem can be solved using Newton's law of cooling, which states that the rate of change of temperature of an object is proportional to the difference in temperature between the object and its surroundings. Mathematically, this can be represented as:

T(t) = T_s + (T₀ - T_s) e^(-kt)

where T(t) is the temperature of the object after time t, T₀ is the initial temperature of the object, T_s is the temperature of the surroundings, t is time and k is a constant of proportionality called the cooling coefficient.

Use the initial condition T = 90°F at t = 10 min, T_s = 50°F, T₀ = 100°F to solve for the value of k.

T(t) = T_s + (T₀ - T_s) e^(-kt)

90°F = 50°F + (100°F - 50°F) e^(-k)(10)

40°F = 50°F e^(-k)(10)

e^-10k = 0.8

k = 0.0223

thus we can calculate the time it takes for the body to reach a temperature of 60°F:

T(t) = T_s + (T₀ - T_s) e^(-kt)

60°F = 50°F + (100°F - 50°F) e^(-0.0223)(t)

10°F = 50°F e^(-0.0223)(t)

e^(-0.0223)(t) = 0.2

The weight of the truck is approximately 254,979 N or 254.9 kN

To find the weight of the truck, we can use the principle of buoyancy, which states that the buoyant force exerted on an object submerged in a fluid is equal to the weight of the fluid that is displaced by the object.

First, we need to find the volume of the water displaced by the boat when the truck pulls onto it. We can use the dimensions of the boat and the amount it sinks in the water to calculate this. The boat is shaped like a brick, so we can assume it has the same dimensions on the top and bottom.

The boat's width is 7.7 m and its length is 6.2 m. The boat sinks 5.57 cm or 0.0557 m in the water.

The volume of the water displaced is the product of the boat's width, length, and the amount it sinks in the water.

Volume of water displaced = 7.7 m x 6.2 m x 0.0557 m = 25.9 m^3

Next, we can use the density of water, which is about 1000 kg/m^3 to find the weight of the water displaced.

Weight of water displaced = 1000 kg/m^3 x 25.9 m^3 = 25900 kg

Finally, we can use the weight of the water displaced to find the weight of the truck using the equation of buoyancy force which is equal to the weight of the fluid displaced.

Weight of truck = weight of water displaced x g

Weight of truck = 25900 kg x 9.81 m/s^2 = 254979 N

Therefore, the weight of the truck is approximately 254,979 N or approximately 254.9 kN.
