Explanation: im pretty sure it’s C, because thermodynamics is the movement of heat. Kinda like an EMF Reader. (Electric Magnetic Feild reader). It’s complicated to explain how it works, but hey it works!

(a) The mass at time t=0 is 460 grams. (b) Rounding to at least one decimal place, the mass last after 45 years is about 119.0 grams.

(a) To find the mass at time t=0, we alternative into the given characteristic:

m(0) = \(460e^(-0.03(0))\)

Since \(e^0\) is the same for at least one, we've got:

m(0) = 460(1) = 460 grams

Therefore, the mass at time t=0 is 460 grams.

(b) To locate the mass final after 45 years, we substitute t=45 into the given function:

m(45) = \(460e^(-0.03(45))\)

Using a calculator or software program, we will evaluate the expression:

m(45) ≈ \(460e^(-1.35\)) ≈ 460(0.2587) ≈ 118.96 grams

Rounding to at least one decimal location, the mass last after 45 years is about 119.0 grams.

Answer:

Explanation:

You didn't ask a question here, but I assume you want the pressure? You can use the ideal gas equation stating that:

PV = nRT

The 'P' is pressure, the 'V' is volume, the 'n is number of moles of gas, the 'R' is the ideal gas constant, and the 'T' is the temperature. First convert the Celsius degrees into Kelvin by using the following relation:

C + 273.15 = K

4 + 273.15 = 277.15K

Now, find the volume of a cylinder by using:

\(V=\pi r^2l\)

The 'l' is the length of the cylinder

Now just plug and chug everything into the ideal gas equation:

\(PV=nRT\)

\(P(\pi r^2l)=(5moles)(8.3145J/moles*K)(277.15K)P=\frac{11.52J}{\pi r^2l}\)

(A) The solution X is unsaturated

(B) The solution Y should contain 2.9 g solute in 1000 mL solution.

(C) The percentage by mass of the solute is 40%

(A) The type of solution X is determined as follows;

The maximum amount of solute that can dissolve in solution  X  =  29 g/Liter

The amount of solute in solution X = 2.9 g/Liter

This solution is unsaturated because the amount of solute present is less than the maximum the solution can take.

(B) The amount solute and volume in the solution Y is calculated as follows;

The solubility = 2.9 g/Liter

\(solubility = \frac{2.9 \ g}{L} \times \frac{L}{ mL \times 1000} = \frac{2.9 \ g}{1000mL}\)

Thus, the solution should contain 2.9 g solute in 1000 mL solution.

(C) The percentage by mass of the solute is calculated as;

\(mass \ \% = \frac{20 \ g}{50 \ g} \times 100 \% = 40 \%\)

The rope's center flag remains stationary. Because the force being provided by your team to pull the flag is equal to the force being exerted by the opposing team but in the opposite direction, the flag does not move. The forces are acting in opposing ways.

It balances the forces acting on the rope. The flag in the middle of the rope won't move when the forces are balanced. One team must exert more force than the other in order to win the game.

Two forces are said to be balanced when their strengths are equal but their directions of action are opposing. Once more, tug-of-war is a prime illustration.

The half-meter rule (easy math) is 0.5 meters or 50 centimeters since a meter is 1 meters long, which is equivalent to 100 centimeters. Therefore, we shall apply the 50 cm rule.

A 50 cm rule's center of mass is now 25 cm away.

Additionally, according to the data, the object is pivoted at 15 cm, while the 40 g object is hung at 2 cm from the rule's beginning. Using a straightforward formula, we can compare the two situations: the distance from the pivot to the center of the mass times the mass of the 40 g object divided by 2 cm must equal the distance from the pivot to the center of the mass times mass of the 10 x g object

The result of the straightforward computation must be 52g.

Most simplified version:

the center of mass of the rule is at the 25 cm mark

⇒ \(40 g * (15 cm - 2 cm)\)

⇒ \(= M * (25 cm - 15 cm)\)

Answer:

The horizontal distance is 136.6 m.

Explanation:

Given that,

Initial speed = 38 m/s

Angle = 34°

Suppose, Calculate the horizontal distance \(x_{max}\) in meters the ball has traveled when it returns to ground level.

We need to calculate the horizontal distance

Using formula of range

\(R=\dfrac{v_{0}^2\sin(2\theta)}{g}\)

Where, v= speed

g = acceleration due to gravity

Put the value into the formula

\(R=\dfrac{(38)^2\sin(2\times34)}{9.8}\)

\(R=136.6\ m\)

Hence, The horizontal distance is 136.6 m.

For the 100 litre open-topped tank:

a) To find an equation that gives the amount of salt remaining in the tank after t seconds, consider the rate at which salt enters and leaves the tank.

The initial amount of salt in the tank is 100 L × 80 g/L = 8000 g.

Rate of salt entering the tank:

The fresh water entering the tank at 10 L/sec has a salt concentration of 0 g/L. Therefore, the rate of salt entering the tank is 0 g/sec.

Rate of salt leaving the tank:

The excess water running out over the top at 10 L/sec carries away salt with a concentration of 80 g/L. Therefore, the rate of salt leaving the tank is 80 g/sec.

Rate of change of salt in the tank:

The rate of change of salt in the tank is given by the difference between the rate of salt entering and leaving the tank:

dS/dt = 0 - 80 = -80 g/sec

b) To find how much salt is left in the tank after one minute (60 seconds), integrate the rate equation from t = 0 to t = 60:

∫dS = ∫(-80) dt

ΔS = -80t + C

Since the initial amount of salt is 8000 g (at t = 0), solve for the constant C:

8000 = -80(0) + C

C = 8000

Therefore, the equation for the amount of salt remaining in the tank after t seconds is:

S(t) = -80t + 8000

Substituting t = 60 seconds:

S(60) = -80(60) + 8000

S(60) = 3200 g

c) After 100 L of brine has flowed out over the top of the tank, the remaining volume of salt water in the tank is 100 L (initial volume) - 100 L (flowed out) = 0 L. Therefore, there is no salt left in the tank.

d) To find when half of the salt in the tank has flowed out over the top,  set S(t) = 0.5 × initial amount of salt:

0.5 × 8000 = -80t + 8000

-80t = 8000 - 4000

-80t = 4000

t = -4000 / -80

t = 50 seconds

Therefore, half of the salt in the tank will have flowed out over the top after 50 seconds.

e) To find when the tank contains salt water at a concentration of 5 g/L, set S(t) = V(t) × 5, where V(t) is the volume of water in the tank at time t:

V(t) × 5 = -80t + 8000

V(t) = (-80t + 8000) / 5

V(t) = 100 L (initial volume) - 10 L/sec × t (rate of water leaving the tank):

100 - 10t = (-80t + 8000) / 5

Multiplying both sides by 5:

500 - 50t = -80t + 8000

30t = 7500

t = 250 seconds

Therefore, the tank will contain salt water at a concentration of 5 g/L after 250 seconds.

Solution :-

Given :

Distance 1 = 30 km

Distance 2 = 70 km

We know that speed = distance/time

and, Average speed = total distance/total time taken

When the train acquired a speed of 30 km/hr, the time taken = 30/30 = 1 hour

Average speed = 9distance 1 + distance 2)/(time 1 + time 2)

AS time 2 or t2 is time taken for the second part of the journey of 70 km

⇒ 40 = 100/(1 + t2)

⇒ 40 + 40t2 = 100

⇒ 40t2 = 100 - 40

⇒ 40t2 = 60

⇒ t2 = 60/40

⇒ t2 = 1.5

So, t2 or time taken to travel the second part of the journey is 1.5 hours.

Speed of the second part of the journey = distance 2/time 2

⇒ 70/1.5

⇒ 46.666 km/hr or 46.7 km/hr.

Hence the answer is = 46.666 km/hr or 46.7 km/hr.

Since the wires are made of the same material, resistivity of wire X = resistivity of wire Y

let wire X = 1

let wire Y = 2
