a rectangular tank measures 12.5 metres long 10.0 wide and 2.0 metre high calculate the mass of the water in the tank when it is full the density of water 1000 kg per metre cube assume the measurement are internal
Answer:
250000kg
Explanation:
Mass =density * volume
Density=1000kg/m³
Volume=l*w*h
12.5*10.0*2.0=250m³
Mass=1000 *250
=250000kg

A boy jumps into an indoor swimming pool. He notices that the water appears to get colder as he
goes deeper underwater. This is due to convection
Which statement is correct?
Cold water is more dense than warm water so it sinks to the bottom of the pool.
Warm water is more dense than cold water so it rises to the surface of the pool.
The molecules in cold water have more kinetic energy than the molecules
in warm water so
they move to the bottom of the pool faster.
The molecules in warm water are closer together than the molecules in cold water so they
rise to the surface of the pool.
Answer:
cold air is more dense than warm water so it sinks to the bottom of the pool

: where are you likely to find a cooling plant located in the duckwork? A. single family home B. A large apartment C. large factory D. A medium sized offices
Answer:
Option C
Explanation:
In a large sized factory, it is essential to create cooling system based on duct work because it can then be able to regulate cooling of any section of the factory from one place. Also, ductwork cooling is preferred in large spaces such as big offices building, towers, factories etc.
Hence, option C is correct

What is the correct order of tasks for washing dishes in a three-compartment sink?
Answer:
The summary of the given statement is explained below throughout the explanation segment.
Explanation:
Drain certain surfaces throughout warm water of such soap during the very first sink. This same sanitizing of bacteria would not destroy whether grime would be in the direction.Exfoliate the plates throughout plain water during the secondary drain. As with grime, the residual soap could avoid the kill off bacteria and viruses by the sanitizer.During a science lesson on changes, Ms. Sloan's students made mixtures of sulfur (the yellow substance) and iron filings (the black substance. Ms. Sloan challenged her students to separate the two substances and one group easily completed the task by using a magnet to lift the iron filings from the mixture. Next, Ms. Sloan poured the same mixture into a test tube and heated it in the Bunsen burner flame. What was the result of heating the mixture?
Answer:
Both substance will melt and become a solution.
Explanation:
When a mixture of iron filings (black substance) and sulphur powder (yellow substance) are heated in a test tube under a bunsen burner, usually they will undergo a chemical reaction where they will melt to form a new solution of ferrous sulphide.
Thus, we can say what happens is that both substances melt to form a solution.

Q: How do you determine speed over a crooked path? Explain.
Answer: If you solve for the orbit speed, v, in the mass formula, you can find how fast something needs to move to balance the inward pull of gravity: v 2 = (G M)/r . Taking the square root of both sides (you want just v not v 2), you get v = Sqrt.

Convert 23.5 mL into L
Answer:
[tex]0.0235l[/tex]
Explanation:
[tex]1l = 1000ml \\ x = 23.5ml \\ \\ x = \frac{23.5 \times 1}{1000} \\ = 0.0235l[/tex]
Hope this helps you.
Can I have the brainliest please?
Answer:0.0235 I hope this is helpful mark me brainlist if correct
Explanation:
To convert any value in milliliters to liters, just multiply the value in milliliters by the conversion factor 0.001. So, 23.5 milliliters times 0.001 is equal to 0.0235 liters.
What is the frequency of a wave when it has a wavelength of 2.17 m and is travelling across a rope at a speed of 31 m/s?
a 10.1 Hz
b 14.3 Hz
c 11.7 Hz
d 16.2 Hz
A wave oscillating on a string has a wavelength of 0.25 m and a frequency of 1.85 Hz. What is the speed of this wave?
a. 1.210 m/s
b. 2.050 m/s
c. 0.2915 m/s
d. 0.4625 m/s
Answer:
i) b. 14.3 Hz
ii) d. 0.4625 m/s
Explanation:
f = c / λ
f = frequency
c = speed
λ = wavelength
first question:
the given values,
λ = 2.17 m
c = 31 m/s
f = c / λ
f = 31 / 2.17
f = 14.28
∴ f = 14.3 Hz
second question:
given,
λ = 0.25 m
f = 1.85 Hz
f = c / λ
rearranging,
c = f × λ
c = 1.85 × 0.25
c = 0.4625
∴ c = 0.4625 m/s

Three resistors, 3.0 Ω, 12 Ω, and 4.0 Ω, are connected in parallel across a 6.0-V battery as shown above. What is the current through the battery?
Answer:
the current flowing through the battery is 4 A.
Explanation:
Given;
resistance of the three resistors in parallel, R₁, R₂ and R₃ = 3.0 Ω, 12 Ω, and 4.0 Ω
voltage of the battery, V = 6.0 V
The equivalent resistance is calculated as follows;
[tex]\frac{1}{R_T} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} \\\\\frac{1}{R_T} = \frac{1}{3} + \frac{1}{12} + \frac{1}{4} \\\\\frac{1}{R_T} = \frac{4 \ + \ 1 \ + \ 3}{12} \\\\\frac{1}{R_T} = \frac{8}{12} \\\\\frac{1}{R_T} = \frac{2}{3} \\\\R_T = \frac{3}{2} \\\\R_T = 1.5 \ ohms[/tex]
The current flowing through the battery is calculated as follows;
[tex]I = \frac{V}{R_T} \\\\I = \frac{6}{1.5} \\\\I = 4 \ A[/tex]
Therefore, the current flowing through the battery is 4 A.

Lloyd walks faster than
Ronald, with a speed of
about 0.65 m/s. The canteen
is 15 meters away from their
dassroom. How many
minutes will take her to go
to the canteen?
Answer:
Time = 2.6 minutes
Explanation:
Given the following data;
Speed = 0.65 m/s
Distance = 15 meters
To find the time to get to the canteen;
Mathematically, time is given by the formula;
Time = distance/speed
Substituting into the formula, we have;
Time = 15/0.65
Time = 23.08 seconds
To minutes = 60/23.08 = 2.6 minutes
A battery is connected to a 10 resistor and produces a current of 0.2 A in the circuit. If the resistor is replaced with a 20 resistor, what is the new
current in the circuit?
Answer:
0.1 A
Explanation:
From the question,
V = IR............ Equation 1
Where V = Voltage, I = current, R = Resistance.
Given: I = 0.2 A, R = 10 ohms.
Substitute into equation 1
V = 0.2(10)
V = 2 volt,
If the resistor is replaced with a 20 resistor, The nwe current is
I = V/R................ Equation 2
I = 2/20
I = 0.1 A
