For cars W and Z, the set of equations x=x0+v0xt+12axt2 and x=x0+v0xt+12axt2 could be used to determine where on the horizontal surface the two cars will collide.

Due to the fact that we know the automobiles will collide at the same moment, by solving for t in one equation and substituting the new expression for t into the other, all variables other than x will be known. A formula that connects two expressions with the equals sign to express the equality of the two is known as an equation. We will apply the equations X=X0+v0xt+12axt2 for car W and x=x0+v0xt+12axt2 for car Z to find the point on the horizontal surface where the two cars meet. The rationale is that we are aware that the two cars will collide at the same location and time.

Answer:

Weight Percentage of Ash = 3.4

Explanation:

Given - Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min.

To find - the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly ?

Solution -

Given that,

Coal Burned Rate = 10,000 kg/hr

                              = \(\frac{10,000}{60 min} * 1 hr *\frac{kg}{hr}\)

                              = 166.6666 kg/min

⇒Coal Burned Rate = 166.6666 kg/min

Now,

Given that,

Ash content in coal = 21 %

⇒Ash in (coal that burned) = 166.6666 × \(\frac{21}{100}\) kg/min

                                             = 34.9999 ≈ 35 kg/min

⇒Ash in (coal that burned) = 35 kg/min

Now,

We know,

Density of water = 1000 kg/m³

Now,

Water flow Rate = \(1\frac{m^{3} }{min} * density\)

                           = 1000 kg/min

⇒Water flow Rate = 1000 kg/min

Now,

Total Mass flow Rate of (Water + Ash stream) = ( 1000 + 35) kg/min

                                                                           = 1035 kg/min

⇒Total Mass flow Rate of (Water + Ash stream) = 1035 kg/min

So,

Weight Percentage of Ash = (Weight of Ash ÷ Total weight of Stream) × 100

                                            = (35 ÷ 1035) × 100

                                            = 3.38 ≈ 3.4

∴ we get

Weight Percentage of Ash = 3.4

Space Rovers

Explanation:

The engineering advancement of the invention space rovers has changed space exploration tremendously. The first space rover ever to go out onto another planet was made by NASA and put on mars to learn more about the red planet and see if there where any plausible signs of past or maybe even present life. This mission was incredibly successful and for the first time in space exploration history, there was a spacecraft that you could move around that could with do the conditions of the planet for weeks, months, sometimes years at a time, moving around taking pictures and constantly collecting data. This was revolutionary for scientists, this way they could get copious amounts of information just on rover and not having to send multiple crafts only to die in the first few hours but sending back a relative amount of information. With rovers you can have them collect samples and bring the back to earth, not something  that could’ve been done without a human, until rovers. They have completely changed and improved collecting data from other planets and have been one of the most revolutionary inventions when it comes to space exploration.

Explanation:

m = Mass of automobile = 1100 kg

v = Velocity of car = 120 km/h = \(\dfrac{120}{3.6}\ \text{m/s}\)

h = Height of hill = 80 m

Change in kinetic energy

\(KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}\)

Change in kinetic energy is \(-6111.11\ \text{kJ}\)

Change in potential energy is given by

\(PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}\)

The change in potential energy is \(863.28\ \text{kJ}\).

[b]. the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.

Explanation:

Atoms are referred to be the smallest units of a substance although it can be sub-divided into smaller units such as proton, neutron and electron. When atoms combines in group they form a molecule.

From the question above it is seen that two substances were mixed together to give two ending substances that is:

substance A [ colorless liquid with a strong smell] + substance B[white solid with no smell] ---------> substance C[ repeating group of atoms shown above on the right] + substance D.

The ending substance that is, substance C is the same substance as substance A which is the colorless liquid with a strong smell.

When the substance A reacted with substance B, it gives substance C and D that is the ending substances are the products of the reaction between A and B.

Hence, the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.

The selection of shaft keys is critical in preventing premature failure of keyed joints. Shaft keyways and keys are used to transmit torque from shafts to mechanical transmission elements such as gears, pulleys, and so on.

A key to preventing early failure of keyed joints is choosing the right shaft key. The use of a keyed joint allows for the transmission of torque from shafts to mechanical transmission components like gears, pulleys, etc. They can be produced using a standard stock material, like key stock, or they can be specially machined to fit the application.

According to various standards like BS4235, the nominal shaft diameter is typically used to specify the key size, and the commonly accessible rectangular key is used for the majority of applications. As a result, the standards do not specify the key material or joint limitations, and a keyed joint is oversized to support all loads.

There are four main groups of shaft keys:

Stainless steel or medium carbon steel are typically used to make shaft keys. To suit various application environments, they can be made from a wide variety of materials, including bronze, copper, brass, and aluminum alloy. For example, stainless steel grade for use in food service equipment and brass or bronze keys for marine propeller shafts.

Key steel is typically supplied in accordance with BS46 and BS4235 and is a medium carbon steel that is unalloyed and has a respectable tensile strength. Due to their ideal blend of strength, toughness, and favorable machining properties, unalloyed medium carbon steels with carbon contents ranging from 0.25% to 0.60% are used.

The total wall area that needs to be insulated is -29 ft².

The negative value indicates that the area of the window and door openings exceeds the total wall area, which seems unlikely. It's important to note that the given dimensions or calculations might contain errors or inconsistencies. Double-checking the measurements or obtaining accurate dimensions will be necessary to provide a valid answer.

To determine the total wall area that needs to be insulated, we first need to calculate the area of the window and door openings and subtract it from the total wall area.

The dimensions of the window and door openings are not provided, but we know that their combined area is approximately 125 ft². Let's assume that the window and door openings are rectangular in shape.

Let's calculate the area of the window and door openings:

Area = Length × Width

Given that the combined area is 125 ft², we can assume:

Area of window and door openings = 125 ft²

Now, let's calculate the total wall area that needs to be insulated:

Total wall area = Wall area - Area of window and door openings

To calculate the wall area, we need to find the perimeter of the home and multiply it by the height of the walls. Assuming the home is rectangular:

Perimeter = 2 × (Length + Width)

Total wall area = Perimeter × Height

Let's substitute the given dimensions into the equations:

Perimeter = 2 × (42" + 30") = 144 inches

Total wall area = (144 inches × 8 feet) / 12 = 96 ft²

Finally, we can calculate the total wall area that needs to be insulated:

Total wall area = 96 ft² - 125 ft² = -29 ft²

The negative value indicates that the area of the window and door openings exceeds the total wall area, which seems unlikely. It's important to note that the given dimensions or calculations might contain errors or inconsistencies. Double-checking the measurements or obtaining accurate dimensions will be necessary to provide a valid answer.

Answer:

(a) 12 seconds (b) t = 8.31 seconds (c) 10µ A (d) V = 20 V (e) V =0

Explanation:

Solution

Given that:

C = 6 µ which is = 6 * 10^ ⁻6

R = 2 MΩ, which is = 2 * 10^ 6

ε = 20 V

(a) When it is at the time constant we have the following:

λ = CR

= 6 * 10^ ⁻6 * 2 * 10^ 6

λ =12 seconds

(b) We solve for the half life of the circuit which is given below:

d₀ = d₀ [ 1- e ^ ⁺t/CR

d = decay mode]

d₀/2 =  d₀  1- e ^ ⁺t/12

2^⁻1 = e ^ ⁺t/12

Thus

t/12 ln 2

t = 12 * ln 2

t = 12 * 0.693

t = 8.31 seconds

(c) We find the current at t = 0

So,

I = d₀/dt

I = d₀/dt e ^ ⁺t/CR

= CE/CR e ^ ⁺t/CR

E/R e ^ ⁺t/CR

Thus,

at t = 0

I  E/R = 20/  2 * 10^ 6

= 10µ A

(d) We find the voltage across the capacitor at t = 0 which is shown below:

V = IR

= 10 * 10^ ⁻6 * 2 * 10^ 6

V = 20 V

(e)  We solve for he voltage across the resistor.

At t = 0
