A 0. 22 kg clay target is fired at an angle of 35° to the horizontal. It reaches a maximum height of 4. 6 m. Its initial speed when it is launched will be u = 16.66 m/s

Projectile motion is the motion of an object thrown (projected) into the air. After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory.

The object's maximum height is the highest vertical position along its trajectory. The horizontal displacement of the projectile is called the range of the projectile. The range of the projectile depends on the object's initial velocity.

Answer:

\(V =-7221.43 \ V\)

Explanation:

The Electric Potential

The electric potential at a point is equal to the electric potential energy (measured in joules) of any charged particle at that location divided by the charge (measured in coulombs) of the particle.

To calculate the electric potential of a point charge Q at a distance r, we use the formula:

\(\displaystyle V=\frac{kQ}{r}\)

The equilibrant force is equal in magnitude and opposite in direction to the resultant force.

Since the resultant force is 10 N in the positive y axis direction (North), the equilibrant force is 10 N in the negative y axis direction (South). An equilibrant force is a force that can balance or counteract the effect of other forces acting on an object.

It has the same magnitude as the resultant force, but it acts in the opposite direction, resulting in a state of equilibrium where the net force acting on the object is zero.

Answer:

The x-component of \(F_{3}\) is 56.148 newtons.

Explanation:

From 1st and 2nd Newton's Law we know that a system is at rest when net acceleration is zero. Then, the vectorial sum of the three forces must be equal to zero. That is:

\(\vec F_{1} + \vec F_{2} + \vec F_{3} = \vec O\) (1)

Where:

\(\vec F_{1}\), \(\vec F_{2}\), \(\vec F_{3}\) - External forces exerted on the ring, measured in newtons.

\(\vec O\) - Vector zero, measured in newtons.

If we know that \(\vec F_{1} = (70.711,70.711)\,[N]\), \(\vec F_{2} = (-126.859, 46.173)\,[N]\), \(F_{3} = (F_{3,x},F_{3,y})\) and \(\vec O = (0,0)\,[N]\), then we construct the following system of linear equations:

\(\Sigma F_{x} = 70.711\,N - 126.859\,N +F_{3,x} = 0\,N\) (2)

\(\Sigma F_{y} = 70.711\,N + 46.173\,N+F_{3,y} = 0\,N\) (3)

The solution of this system is:

\(F_{3,x} = 56.148\,N\), \(F_{3,y} = -116.884\,N\)

The x-component of \(F_{3}\) is 56.148 newtons.

When an object is placed inside the focal point of a concave mirror, the image formed will be virtual, upright, and magnified.

This occurs because the light rays reflecting off the mirror diverge and never intersect on the real side of the mirror. Instead, they appear to converge on the virtual side, behind the mirror.

As a result, the image of the object will be farther from the observer than the object itself. The observer will see the image behind the mirror, which is not the actual position of the object, making it appear more distant than it truly is.

Explanation:

For an electric company, it would make more sense to charge by the watt rather than by the joule.

The joule is a unit of energy, while the watt is a unit of power. Power is the rate at which energy is consumed or produced. When we use electricity, we are consuming power, not energy.

Charging by the joule would mean that customers would be paying for the total amount of energy consumed, regardless of the rate at which it was consumed. This would not be practical, as it would be difficult for customers to estimate how much energy they would need and how quickly they would consume it. It would also be difficult for the electric company to price its services in a way that accurately reflects the value of the electricity being consumed.

Charging by the watt, on the other hand, would mean that customers would be paying for the rate at which they consume electricity. This is more practical, as it is easier for customers to estimate their power needs and for the electric company to price its services based on the rate at which electricity is being consumed.

Therefore, it makes more sense for an electric company to charge by the watt rather than by the joule.

To find the induced current in the gold alloy wedding band, you can use Ohm's Law and the given information. Ohm's Law states that Voltage (V) = Current (I) * Resistance (R). We know the induced EMF (E) is 4.8 V, the resistivity of the gold alloy (ρ) is 6.2 × 10^(-8) Ω·m, and the cross-section area (A) is 4.5 mm^2.

Explanation:

First, let's find the length (l) of the band. We know the diameter of the band is 2.2 cm, so the circumference (which is equal to the length) can be found using the formula C = π * diameter:

l = π * 2.2 cm = 6.91 cm (approximately)

Next, we need to calculate the resistance (R) of the band. We can use the formula R = ρ * (l / A):

Since the area is given in mm^2, we need to convert the length to mm:
l = 6.91 cm * 10 = 69.1 mm

Now, let's convert the area from mm^2 to m^2:
A = 4.5 mm^2 * 10^(-6) = 4.5 × 10^(-6) m^2

Now we can find the resistance:
R = (6.2 × 10^(-8) Ω·m) * (69.1 mm / 4.5 × 10^(-6) m^2) = 0.0959 Ω (approximately)

Finally, we can find the induced current (I) using Ohm's Law:
I = E / R = 4.8 V / 0.0959 Ω ≈ 50.05 A

So, the induced current in the gold alloy wedding band is approximately 50.05 A.

The relay described in the question is called the "thermal overload" relay. It utilizes a resistive wire connected in series with the motor to measure motor current.

The thermal overload relay is designed to protect motors from damage due to excessive current. It employs a length of resistive wire, also known as a heating element or heater, which is placed in series with the motor circuit. When current flows through the motor, it also passes through the resistive wire. As current flows, the wire heats up due to its electrical resistance.

The resistance wire is typically made of a material with a positive temperature coefficient, meaning its resistance increases with temperature. As the current passing through the wire increases, it generates more heat, causing the wire's temperature to rise. When the temperature reaches a certain threshold, the relay is triggered.

The increased temperature of the resistive wire causes it to expand, activating the relay's switching mechanism. This mechanism can then disconnect the motor from the power source, protecting it from further damage.

Therefore, the thermal overload relay utilizes a length of resistive wire in series with the motor to sense motor current and protect the motor from excessive current levels.
