The engineer must design an engine that can produce a force of over 3,100 Newtons.

A force is an energy that can cause change of motion. It can be a push or a pull. It also has both magnitude and direction, making it a vector quantity.

From the question;

total mass = mass of person + mass of cart

total mass = 80kg + 75kg

total mass = 155kg

acceleration = 20m/s²

The formula to be used;

F = m x a

F = 155kg x 20m/s²

F = 3,100N

In conclusion, the engineer needs a minimum force of 3,100 N in the engine to be able to power the cart.

Due to first charge , electric field at origin will be oriented towards - ve of y axis.

magnitude

Ey = -8.99 x 10⁹ x 4.1 x 10⁻⁹ / 1.08² j

= - 31.6 j N/C

Due to second charge electric field at origin

= 8.99 x 10⁹ x 3.6  x 10⁻⁹ / 1.2²+ .6²

= 8.99 x 10⁹ x 3.6  x 10⁻⁹ / 1.8

= 18 N/C

It is making angle θ where

Tanθ = .6 / 1.2

The voltage drop across R3 is 34.5 volts.

Voltage, also known as electric potential difference, is a measure of the difference in electric potential energy between two points in an electrical circuit, and it is measured in volts. It is the driving force that moves electric charges through a circuit, from a higher potential to a lower potential.

To determine the voltage drop across R3 in this circuit, we need to first find the equivalent resistance of R2, R3, and R4, since they are connected in parallel. We can then find the total resistance of the circuit by adding the equivalent resistance in series with R1, and finally use Ohm's Law to calculate the voltage drop across R3.

The equivalent resistance of R2, R3, and R4 in parallel can be calculated as:

1/R_parallel = 1/R2 + 1/R3 + 1/R4

1/R_parallel = 1/20 + 1/25 + 1/10

1/R_parallel = 0.15

R_parallel = 1/0.15

R_parallel = 6.67 ohm

The total resistance of the circuit can be found by adding R1 and the equivalent resistance in series:

R_total = R1 + R_parallel

R_total = 15 + 6.67

R_total = 21.67 ohm

Now we can use Ohm's Law to calculate the current flowing through the circuit:

I = ET / R_total

I = 30 / 21.67

I = 1.38 A

Finally, we can use Ohm's Law again to calculate the voltage drop across R3:

V_R3 = I * R3

V_R3 = 1.38 * 25

V_R3 = 34.5 V

Therefore, the voltage drop across R3 is 34.5 volts.

Answer:

you could put the iron filings on the peace of paper and hover a magnet over top of the paper and the iron filings would stand up, or even stick to the magnet

Explanation:

The potential energy of the roller coaster is 176,400 J (joules).

The potential energy of an object is given by the formula PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height or vertical position of the object.

In this case, the roller coaster is at a peak of 20m and has a mass of 900kg. The acceleration due to gravity, g, is approximately 9.8 \(m/s^2\).

Using the formula, we can calculate the potential energy:

PE = mgh

= (900 kg)(9.8 \(m/s^2\))(20 m)

= 176,400 J

Therefore, the potential energy of the roller coaster is 176,400 J (joules).

Answer:

 ΔV = -2.1 L

Explanation:

To solve this exercise we can use the ideal gas equation for two points

         PV = nRT

          P₁V₁ = P₂ V₂

where point 1 is on the surface and point 2 is at the desired depth,

          V₂ = \(\frac{P_1}{P_2} \ V_1\)

let's calculate

           V₂ = ( \(\frac{1 atm}{2.5 atm}\) ) 3.5 L

            V₂ = 1.4 L

this is the new volume, the change in volume is

          ΔV = V₂ -V₁

          ΔV = 1.4-3.5

          ΔV = -2.1 L

The forces F3 and F6 form a couple since they are parallel, act in the same directions, and have the same magnitude (both are 3N), but they do not have the same point of application.

A couple is a pair of equal but disjointed forces that act in opposite directions and along parallel lines of force.

The rigid body rotates about its center of mass as a result of the forces acting on it at various places.

We can observe that the forces F3 and F6 in the provided set of forces are parallel, have the same magnitude of 3N, and act in opposite directions.

However, because they are applied to various locations on the rigid body, the body will rotate as a result. The stiff body tends to rotate around its center of mass because of this phenomenon, which is known as a couple.

projectile's vertical speed v yv y v, start , y,  drops prior to reaching its maximum height since its acceleration is in the opposite direction. Since the object's height is rising, the initial direction of the velocity is upward

.

At the projectile's highest point, vertical velocity zeroes out. After reaching the highest point, the vertical speed increases due of the same-direction acceleration. As the object's height lowers, the vertical velocity has a downward direction.

In projectile The beginning vertical velocity determines the maximum height. Increasing the launch angle raises the maximum height because steeper launch angles have a larger vertical velocity component.

Considering the definition of velocity, the average velocity along the trail is 0.608 km/s east.

Velocity is a physical magnitude that relates the displacement of an object, the time it takes to make this change in position and direction. So, it is considered a vector magnitude.

The velocity can be defined as the amount of space traveled per unit of time with which a body moves, considering the direction, and can be calculated using the expression:

velocity= distance traveled÷ time

In this case, you know:

Replacing in the definition of velocity you can obtain the time necessary to travel each trail:

1.7 m/s= 0.7 km÷ time of first half of a straight trail

1.7 m/s× time of first half of a straight trail= 0.7 km

time of first half of a straight trail= 0.7 km÷ 1.7 m/s

time of first half of a straight trail= 0.412 s

0.37 m/s= 0.7 km÷ time of second half of a straight trail

0.37 m/s× time of second half of a straight trail= 0.7 km

time of second half of a straight trail= 0.7 km÷ 0.37 m/s

time of second half of a straight trail= 1.892 s

Then, you know:

Replacing in the definition of velocity:

velocity= 1.4 km÷2.304 s

velocity= 0.608 km/s

Finally, the average velocity along the trail is 0.608 km/s east.

The right sphere will acquire an equal and opposite net positive charge to balance the negative charge on the left sphere.

Since the left sphere is attracted to the positively charged rod, it means that the left sphere acquires a temporary negative charge due to induction.

The positive charge on the rod repels electrons in the left sphere, causing them to move away from the rod side and accumulate on the opposite side, resulting in a net negative charge on the left sphere.

According to the principle of charge conservation, the net charge on the system must remain zero. Therefore, the right sphere acquires an equal and opposite net positive charge to balance the negative charge on the left sphere.

Answer:

the acceleration of the train is - 8 m/s² since it is decelerating as the influence of the brake comes to stop

Explanation:

The electric field inside X is zero and the electric field outside Y is zero. The correct option is C.

This assertion is accurate: There is no electric field inside of X. The charge stays on the outside of a conductor (like sphere X) when too much positive charge is applied to it.

The conductor's internal electric field becomes zero as a result. There is zero net charge inside the conductor since all extra charge is on the exterior surface.

This statement is also accurate: There is no electric field outside of Y. Sphere Y becomes electrically neutral when it is grounded.

The outer surface of sphere Y will have a net charge of zero because any surplus charge will flow into the earth. There is consequently no electric field outside of sphere Y.

Thus, the correct option is C.
