What would happen if the brake pedal was released while the bleed screw was open during brake bleeding?

When block C is in position xC = 0.8 m, its speed is 1.5 m/s to the right. Find the velocity of block A at this instant. Note th

Amanda [17]

Answer:

The answer is "2 m/s".

Explanation:

The triangle from of the right angle:

$\to (x_c-0.8)+(1.5+y_4) +\sqrt{x_c^2 + 1.5^2}= constant$

Differentiating the above equation:

$\to V_c +V_A+ \frac{X_cV_c}{\sqrt{x_c^2 +1}}=0\\\\\to 1-V_A+ \frac{0.8 \times 1.5}{\sqrt{ 0.8^2+1.5}}=0\\\\$

$\to V_A= \frac{1.2}{\sqrt{ 0.64+1.5}}+1\\\\$

$= \frac{1.2}{ 1.46}+1\\\\= \frac{1.2+ 1.46}{ 1.46}\\\\ = \frac{2.66}{1.46}\\\\= 1.82 \ \frac{m}{s}\\\\= 2 \ \frac{m}{s}$

2. Ackermann's Function is a recursive mathematical algorithm that can be used to test how well a system optimizes its performan

oee [108]

The python program is an implementation of the Ackermann function that a system optimizes its performance of recursion.

As per the question,

Here is an implementation of the Ackermann function in Python:

def ackermann(m, n):

if m == 0:

return n + 1

elif n == 0:

return ackermann(m - 1, 1)

else:

return ackermann(m - 1, ackermann(m, n - 1))

# get input values for m and n from the user

m = int(input("Enter an integer value for m: "))

n = int(input("Enter an integer value for n: "))

# calculate and print the result of the Ackermann function

result = ackermann(m, n)

print("Ackermann ({},{}) = {}".format(m, n, result))

This implementation follows the logic described in the prompt, using a recursive function to calculate the result of the Ackermann function for the given values of m and n.

Eight energy corporations made plans to increase their combined spending on efficiency programs to $50 million per year for the

tangare [24]

Answer:

F=531831381

Explanation:

There are two ways of doing this question:

1) By Formula

2) By Using Compound interest Table

By Formula:

$F=A*\frac{(1+i)^{n}-1}{i}$

Where:

F is future value

A is annual amount per year

i is interest rate

n is number of years

$F=50 million*\frac{(1+0.08)^{8}-1}{0.08}$

F=531831381

By Using Compound interest Table:

F=A(F/A,i,n)

From Table F/A at i=8% and n=8 is 10.6366

F=50000000*(10.6366)

F=531830000≅531831381

The difference in two answers is due to decimal points if you take value from table to greater decimal points you will get the exact answer as by using formula.

Naya [18.7K]

Answer:

Not possible.

Explanation:

According to second law of thermodynamics, the maximum efficiency any heat engine could achieve is Carnot Efficiency η defined by:

$\eta=1-\frac{T_{cold}}{T_{hot}}$

Where

$T_{hot}$ and $T_{cold}$ are temperature (in Kelvin) of heat source and heatsink respectively

In our case (I will be using K = 273+°C) :

$\eta=1-\frac{-27+273}{14+273}\\=0.1428$

In percentage, this is 14.28% efficiency, which is the maximum theoretical efficiency any heat engine could have while working between -27 and 14 °C temperature. Any claim of more efficient heat engine between these 2 temperature are violates the second law of thermodynamics. Therefore, the claim must be false.
