How long would it take for a net charge of 2.5C to pass a location in a wire if its to carry a steady current of 5Ma?
Answers
It would take 500 seconds (or 8 minutes and 20 seconds) for a net charge of 2.5C to pass a location in a wire carrying a steady current of 5mA.
To calculate how long it would take for a net charge of 2.5C to pass a location in a wire carrying a steady current of 5mA, we can use the equation:
q = I * t
where q is the charge, I is the current, and t is the time.
Rearranging the equation, we get:
t = q / I
Substituting the values given in the question, we get:
t = 2.5C / 0.005A
Simplifying, we get:
t = 500 seconds
Therefore, it would take 500 seconds
It is important to note that this calculation assumes that the wire is a perfect conductor with no resistance, which is not the case in real-world scenarios. In reality, the wire would have some resistance which would affect the flow of current and the time it takes for the charge to pass through the wire.

Suzie Skydiver with her parachute has a mass of 46kg. Before opening her chute what force of air pressure will she have when she reaches terminal velocity
Answers
Before opening her chute, Suzie Skydiver would experience a force of air pressure of approximately 450 N at terminal velocity.
Terminal velocity is the point where the force of air resistance, or drag, acting on the skydiver becomes equal in magnitude to the force of gravity pulling the skydiver down. At this point, the net force acting on the skydiver is zero, and they fall at a constant velocity. At terminal velocity, Suzie Skydiver is falling at a constant rate, meaning that the force of gravity pulling her down is balanced by the force of air resistance pushing her up.
This force of air resistance, also known as drag, can be calculated using the formula:
F = 1/2 * rho * v^2 * Cd * A,
where F is the force of drag, rho is the density of the air,
v is the velocity of the object,
Cd is the drag coefficient
A is the cross-sectional area of the object.
Assuming that Suzie Skydiver falls in a typical skydiving posture with a drag coefficient of around 1.0 and a cross-sectional area of 1.0 square meter,
Using the standard atmospheric density of 1.2 kg/m³,
We can calculate that her terminal velocity is approximately 54 m/s.
At this velocity, the force of air resistance, or drag, acting on Suzie Skydiver is equal in magnitude to the force of gravity, which is approximately 450 N.

Succession refers to the sequence or circumstances in which one person succeeds to something after another. In the game of volleyball, except when it is played off a hard-driven spiked ball or is blocked and then played again by the blocker, a ball contacting the body more than once in succession is deemed a double hit and is prohibited.
The given question explains the volleyball regulations, and it is typically accurate that if two or more players make simultaneous contact with the ball, it counts as one play and nobody of those players may take part in the subsequent play.

A car accelerates from an initial velocity of vi=20 m/s to a final velocity of bc=35 m/s in a time interval of 5 s find avarage acceleration
Answers
Answer:
Average acceleration of the car = 3 m/s²
Explanation:
According to the question,
Initial velocity of the car (\( \rm v_i \)) = 20 m/s
Final velocity of the car (\( \rm v_f \)) = 35 m/s
Time interval of uniform acceleration (t) = 5 s
By using \( 1^{st} \) kinematic equation and substituting value we get:
\( \rm \implies v_f = v_i + at \\ \\ \rm \implies at = v_f - v_i \\ \\ \rm \implies a = \dfrac{v_f - v_i }{t} \\ \\ \rm \implies a = \dfrac{35 - 20 }{5} \\ \\ \rm \implies a = \frac{15}{5} \\ \\ \rm \implies a = 3 \: m {s}^{ - 2} \)

Answers
ANSWER:
(a) 0.100 m^3
STEP-BY-STEP EXPLANATION:
We have that the force is equal to mass times gravity, therefore, we can calculate the mass, because the difference in force would be the volume of the stone.
Therefore
\(\begin{gathered} F=m\cdot a \\ m=\frac{F}{a} \\ m=\frac{1235-254}{9.8}=100.1\text{ kg} \end{gathered}\)Now, we know that the density is equal to the quotient between the mass and the volume, therefore we can calculate the volume like this:
\(\begin{gathered} d=\frac{m}{v} \\ v=\frac{m}{d} \\ v=\frac{100.1}{1000} \\ v=0.1001\cong0.100m^3 \end{gathered}\)Therefore the volume of the piece is 0.100 cubic meters.
one bullet is fired horizontally and a second bullet is simultaneously dropped from the same height. ignoring air resistance, which bullet will hit the ground first?
Answers
Both bullets will hit the ground at the same time, regardless of their initial horizontal velocity or any other factors, as long as air resistance is negligible. This is because, in the absence of air resistance, the horizontal motion of the fired bullet does not affect the time it takes to fall to the ground.
When the two bullets are released at the same height, they both have the same initial vertical velocity of zero. Therefore, they will both experience the same acceleration due to gravity as they fall toward the ground, and reach the ground at the same time. This phenomenon is famously demonstrated by Galileo's experiment of dropping objects of different masses from the Leaning Tower of Pisa. Despite the different masses, they all hit the ground at the same time because they experience the same acceleration due to gravity.

Answers
The component Δrₓ of the chipmunk's displacement vector is approximately -4.72 m, and the component Δrᵧ is approximately 6.48 m.
To find the components Δrₓ and Δrᵧ of the chipmunk's displacement vector, we need to calculate the change in position along the x-axis and y-axis, respectively.
The change in position (Δr) can be calculated by subtracting the initial position vector (r₁) from the final position vector (r₂):
Δr = r₂ - r₁
Given:
Initial position vector r₁ = (3.49 m, -2.21 m)
Final position vector r₂ = (-1.23 m, 4.27 m)
Δrₓ = r₂ₓ - r₁ₓ
Δrᵧ = r₂ᵧ - r₁ᵧ
Substituting the values:
Δrₓ = (-1.23 m) - (3.49 m)
Δrᵧ = (4.27 m) - (-2.21 m)
Calculating:
Δrₓ = -1.23 m - 3.49 m
Δrₓ = -4.72 m
Δrᵧ = 4.27 m + 2.21 m
Δrᵧ = 6.48 m
Therefore, the component Δrₓ of the chipmunk's displacement vector is approximately -4.72 m, and the component Δrᵧ is approximately 6.48 m.

Answers
Option A,C It decrease the strength of the magnet and also decrease the number of coils in the solenoid.
A device called a solenoid is made up of a casing, a coil of wire, and a moving plunger (armature). A magnetic field develops around the coil when an electrical current is injected, drawing the plunger in. A solenoid, put more plainly, changes electrical energy into mechanical work.
Copper wire is twisted tightly in a coil that has several turns. The creation of a powerful magnetic field or flux occurs when an electrical current runs through this wire.
The coil is enclosed in a housing, which is often composed of steel or iron, which concentrates the magnetic field it produces.
The magnetic field's concentration, which provides the mechanical force needed to perform the action, draws the plunger to the stop.
