How do I remove the paint from the carpet. Please I need a real answer.
Answer:
Explanation:
(water based paint)
If the paint stain is still wet, simply blot the spot with a wet paper towel - don’t scrub, just blot.
If the paint stain is dry, use hot water and a little bit of dish detergent. Let the solution sit for a few minutes to soften the paint.
Once the paint is softened, use a knife or pin to scrape the paint stain. Continue to add more solution as you scrape.
If the paint is still not softening, consider using a handheld steamer while you scrape to eventually remove the paint stain from the carpet.
(latex based paint)
Blot the spot to remove as much wet paint as possible – don’t scrub, or you’ll push the paint further down into the carpeting.
Mix a cup of lukewarm water with one teaspoon of dishwashing detergent – just make sure the detergent is mild.
Work from the outside of the paint stain to the inside, gently blotting the affected area.
After letting the area dry completely, follow up by vacuuming.
(oil based paint)
If the paint stain is dry, you’ll want to use a steamer to soften the stain.
Apply steam directly to the stain.
Simultaneously pick at the paint stain with a needle or a pin to try and break it up.
Continue until stain is removed, without damaging fibers.
Determine the specific heat of a certain metal if a 450 gram sample of it loses 34 500 Joules of heat as its temperature starts at 150 oC and drops to 53 oC.
Answer:
c = 0.4356 J/gK
Explanation:
Given the following data;
Mass = 450 grams
Initial temperature, T1 = 150°C
Final temperature, T2 = 53°C
Quantity of heat = 34500 Joules
To find the specific heat capacity of the metal;
Heat capacity is given by the formula;
[tex] Q = mcdt[/tex]
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 53 - 150
dt = -97°C
Converting the temperature in Celsius to Kelvin, we have;
dt = 273 + (-97) = 176 Kelvin
Making c the subject of formula, we have;
[tex] c = \frac {Q}{mdt} [/tex]
Substituting into the equation, we have;
[tex] c = \frac {34500}{450*176} [/tex]
[tex] c = \frac {34500}{79200} [/tex]
c = 0.4356 J/gK
What is due to acids formed when atmospheric and volcanic gases mix with water
Answer:
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen, and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

Ribosomes are like tiny “factories” within cells that do all of the following EXCEPT:
Answer: translate DNA into RNA <3
Explanation:
An RNA polymerase binds to promoters and then breaks down hydrogen bonds between two strands of the DNA and attaches on one of them. A DNA strand is used as a template for a new RNA molecule. In this way, pre-mRNA is made, which becomes mRNA after the introns are removed.
A mRNA molecule enters the ribosomes, located in the cytoplasm. In these organelles, a transfer RNA attaches to a mRNA and the process of translation begins. The final product is a polypeptide chain.
Question:
To increase the energy efficiency of their home, a Colorado family
installed a solar panel on its roof. They want to add another solar panel to
increase their ability to store energy for the winter. What happens to the
current (1) when they add another solar panel (V)? *
Answer: When they add another solar panel, there will be INCREASE in current.
Explanation:
The movement of electric charges through a conductor is known as CURRENT (I) and is measured in ampere(A). Voltage is defined as the potential energy that moved charged particles. While resistance is the opposition to the flow of electric charges.
The increase in current abides by the rules of ohm's law which states that the electric current in a given metallic conductor is directly proportional to the potential difference (Voltage) applied between its ends, provided that the temperature of the conductor and other physical factors remain constant. This relationship simply means that increase in voltage will lead to increase in current in a circuit.This can be represented by an equation below:
V= IR
Where V = Voltage
I = Current
R = Resistance
Since increase in voltage lead to increase in current as seen in Ohm's law, therefore the addition of extra solar panels ( voltage) will lead to increase in current out put during winter.
Suppose that the ultrasound source placed on the mother's abdomen produces sound at a frequency 2 MHz (a megahertz is 10^610 6 Hz). Sound travels through tissue at roughly the same speed as in water (v\approx 1500v≈1500m/s). Find the maximum change in frequency between the sound that is emitted by the device and the sound that is observed at the wall of the baby's heart. Treat the heart wall as a moving observer. Hint: you will need to use your answer from part (a). Give your answer as a positive number in Hz.
Answer:
the maximum frequency observed is 2.0044 10⁶ Hz
Explanation:
This is a Doppler effect exercise. Where the emitter is still and the receiver is mobile, therefore the expression that describes the process is
f ’= [tex]f_o \ ( \frac{v \pm v_o}{v} )[/tex]
the + sign is used when the observer approaches the source
typical speeds of a baby's heart stop are around 200 m / min
let's reduce to SI units
v₀ = 200 m / min (1 min / 60 s) = 3.33 m / s
let's calculate
f ’= 2 10⁶ ([tex]\frac{1500 \ \pm 3.33}{1500}[/tex])
f ’= 2.0044 10⁶ Hz
f ’= 1,9956 10⁶ Hz
therefore the maximum frequency observed is 2.0044 10⁶ Hz

A student walks 3 km in 30 minutes. What is the student's average speed in km/h?
Answer:
6km/hr
Explanation:
3km = 30mins
x(km) = 1hr
1hr = 60 x 60 = 3600secs
30min = 30 x 60 = 1800secs
3 x 3,600/x X 1,800
x = 10,800/1,800
x = 6km/hr
To solve the problem we must know about speed, distance, and time.
What is the relationship between Speed, distance, and Time?
We know that speed, distance, and time all are in a relationship with each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
A student walks 3 km in 30 minutes.
We know distance can be written as the product of speed and time, therefore,
[tex]\rm Distance = \rm speed \times \rm Time[/tex]
Substituting the values we get,
[tex]\rm 3\ km = Speed \times 0.5\ hour[/tex]
[tex]\rm speed = \dfrac{3\ km}{0.5\ hour}[/tex]
speed = 15 km\h
Hence, the speed of the student is 15 km\hour.
