Displacement refers to the change in position or location of an object or a point in space. It is a vector quantity that specifies both the magnitude (size or length) and direction of the change in position. Given, displacement vector d = 40.0 m, angle θ = 60.0° east of north. To find the dx and dy components of the vector, we use the trigonometric functions of the angle θ.

So, the dx component of the vector, dx = d cosθ, and the dy component of the vector, dy = d sinθ.

Substituting the given values in the above equations, we get dx = 40.0 m cos(60.0°) ≈ 20.0 m And, dy = 40.0 m sin(60.0°) = 40.0 m × √3 / 2 ≈ 34.64 m.

Hence, the dx component of the vector is approximately 20.0 m and the dy component of the vector is approximately 34.64 m.

The displacement vector d is 40.0 m at an angle of 60.0 degrees east of north. The dx component of the vector is 20.0 m, and the dy component is 34.64 m

To determine the dx and dy components of the vector, we need to decompose the displacement vector d into its horizontal (dx) and vertical (dy) components. The angle given is with respect to the reference direction of north.

The dx component represents the displacement in the horizontal direction (east-west). It can be calculated using the formula dx = d * cos(Ф), where d is the magnitude of the vector and theta is the angle.

In this case, dx = 40.0 m * cos(60.0 degrees) = 40.0 m * 0.5 = 20.0 m.

The dy component represents the displacement in the vertical direction (north-south). It can be calculated using the formula dy = d * sin(Ф), where d is the magnitude of the vector and theta is the angle.

In this case, dy = 40.0 m * sin(60.0 degrees) = 40.0 m * 0.866 = 34.64 m.

Therefore, the dx component of the vector is 20.0 m, and the dy component is 34.64 m.

Part (a) To find the total capacitance of the circuit, we need to use the formula for capacitors in parallel and series. In this case, the accelerationare in both parallel and series, so we need to break it down into steps.

First, we can find the equivalent capacitance of C1 and C2 in parallel: C12 = (C1 x C2) / (C1 + C2) = (7.8 ?F x 13.2 ?F) / (7.8 ?F + 13.2 ?F) = 4.96 ?F.

Then, we can find the total capacitance of C12 and C3 in series: C123 = 1 / ((1 / C12) + (1 / C3)) = 1 / ((1 / 4.96 ?F) + (1 / 4.9 ?F)) = 2.45 ?F.

Therefore, the total capacitance of the circuit is 2.45 ?F.

Part (b) To find the total energy stored in the capacitors, we can use the formula U = 0.5 x C x V^2, where U is the energy stored, C is the capacitance, and V is the voltage.

For C1, U1 = 0.5 x 7.8 ?F x (12 V)^2 = 673.92 ?J.
For C2, U2 = 0.5 x 13.2 ?F x (12 V)^2 = 1,411.2 ?J.
For C3, U3 = 0.5 x 4.9 ?F x (12 V)^2 = 352.8 ?J.

The total energy stored in the capacitors is U = U1 + U2 + U3 = 2,437.92 ?J.

Therefore, the numerical value of the total capacitance of the circuit is 2.45 ?F and the numerical value of the total energy stored in the capacitors is 2,437.92 ?J.

Answer:

The velocity of the rock is 47.24 m/s

The displacement of the rock is 110.48 m

Explanation:

The initial velocity u = 8.0 m/s

time t = 4.0 s

Using

\(v = u + gt\)

where v is the final velocity of the rock after 4.0 s

u is the initial speed = 8 m/s

g is acceleration due to gravity = 9.81 m/s

t is the time = 4.0 s

substituting, we have

\(v = 8 + (9.81*4)\)

\(v = 8 + 39.24\) = 47.24 m/s

Also, using

\(s = ut + \frac{1}{2} gt^{2}\)

where

s is the distance that the stone fell

t is the time = 4.0 s

g is the acceleration due to gravity = 9.81 m/s^2

substituting values, we have

\(s = (8 * 4) + (\frac{1}{2}*9.81*4^{2})\)

s = 32 + 78.48

s = 110.48 m

Given:

By using the relation, we get

→ \(v = u+gt\)

By substituting the values, we get

     \(= 8+(9.8\times 4)\)

     \(= 8+39.24\)

     \(= 47.24 \ m/s\)

hence,

→ \(s = ut+\frac{1}{2} gt^2\)

     \(= (8\times 4)+(\frac{1}{2}\times 9.81\times 4^2 )\)

     \(= 32+78.48\)

     \(= 110.48 \ m\)

If you build a common-source amplifier with an NMOS input transistor, and you want a current source as a load, and that current source goes from VDD to a node, the type of current source would be the diode-connected transistor.

An NMOS current source implemented as a diode-connected transistor is a type of bipolar transistor circuit that creates a constant current from an input voltage. The collector and emitter of the bipolar transistor are connected together in the circuit, effectively turning the transistor into a diode. The main advantage of diode-connected transistors is that they can generate currents of a specific magnitude and not be influenced by changes in the supply voltage.

The current generated by the diode-connected transistor is almost completely determined by the physical characteristics of the transistor and the biasing resistors used in the circuit. Another advantage of diode-connected transistors is that they may be cascaded in series to create current sources of various sizes. These devices have been commonly used to generate reference currents, voltage-to-current (V-I) converters, and bias currents in linear integrated circuits. So therefore diode-connected transistor is the type of current source, if you build a common-source amplifier with an NMOS input transistor, and you want a current source as a load, and that current source goes from VDD to a node.

The train in question is  big and heavy and a car is decently heavy but say a train moving at 55 mph can plow through a car and a car driving at 55mph driving at a train will be stopped dead in its tracks. This is because newtons laws of motion specifically an object in motion will stay in motion unless its opposed. The train also has a payload behind it meaning it hurts with force while a car doesn't have to much mass behind it. The train takes loner to stop for as it's acceleration as well as it's deceleration are very slow because its huge and takes a lot of force to stop it while a car is very centralized and compact when it comes to weight and its brakes are usually effective at stopping at 55 mph in about 2 to 6 seconds while a train might stay moving for a good 35 seconds. The force behind the train is immense for as even if the wheels don't spin at all the train will still move since the force behind it is great and a cars tires have a lot of grip and not a lot mass which plays into the force the car has so it can stop simply.

The crossbow was a more effective weapon than the normal bow because: it used a reel, giving more power to the bow string, it was held horizontally, it shoot a bolt rather than an arrow it could shoot harder and farther. All the options are correct.

A crossbow differs from a standard bow in a few significant ways. The way the bowstring is handled is one of the most obvious variations. Unlike a crossbow, which uses a "trigger" to hold the string in place, a traditional bow requires the archer to hold the string in place with their fingers. This enables the archer to hold the crossbow more loosely, which may improve its accuracy and ease of use.

In terms of how the bowstring is held, how the arrow is loaded and shot, as well as in terms of power and accuracy, a crossbow differs from a regular bow.

The power is: C.1.62W

If the tension is doubled, the new wave speed on a string under tension is approximately 325.27 m/s.

When the tension is doubled, the wave speed on a string under tension becomes twice its previous value. The wave speed on a string under tension is directly proportional to the square root of the tension. This is according to the wave equation.

Here is how to determine the new wave speed if the tension is doubled on a string under tension, given that the wave speed on the string is 230 m/s.

First, we can use the wave equation to determine the wave speed of a string under tension.

It is given as V = √(T/μ)

Where T is the tension, μ is the mass per unit length, and V is the wave speed.

If T doubles, then the new tension will be 2T and the new wave speed will be V1.

Thus,V1 = √((2T)/μ)

= √(2(T/μ))

= √2(√(T/μ))

= √2(V)

The new wave speed V1 is equal to √2 times the original wave speed V.

Thus, the new wave speed is;

V1 = √2(V)

= √2(230)

= 325.27 m/s
