Iron ball sinks in water but not in mercury. Why?
Answer:
mercury is more dense
Explanation:
Explanation:
Iron ball sinks in water but not in mercury because of the difference in the density iron used in iron ball. The iron ball has more density than water and less than the mercury.
Hence, Iron ball sinks in water but not in mercury.

Since the maximum density can be found for a positive temperature, water's own weight will prevent it from freezing from the bottom up. However, the anomalous expansion of water has some negative consequences. ... As the water freezes it expands and can rip pipes open.[tex]{\boxed{\boxed{\tt { What \: is \: the \: state \: of \: anomalous \: expansion \: of \: water? }}}}[/tex]
The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0o C, and it becomes less dense. The density is maximum at 4 degree centigrade and decreases below that temperature as shown in graph#CarryOnLearning

Which statement about the function of the cell membrane of all organisms is not correct? The cell membrane forms a barrier that keeps all substances that might harm the cell from entering the cell. The cell membrane is capable of transforming oxygen and glucose into energy for the cell The cell membrane controls the movement of molecules into and out of the cell.
Answer:
The cell membrane is capable of transforming oxygen and glucose into energy for the cell
Explanation:
The cell membrane encapsulates all the organelles of the cell. It provides protection for the organelles of the cell.
It transports nutrients into the cell and toxic materials out of the cell. It also prevents the entry of harmful materials into the cell.
The cell membrane does not perform the function of transforming oxygen and glucose into energy for the cell.

Calculate the refractive index for a substance where the angle of incidence is 300 , the angle of refraction is 600 , and the refractive index of second substance is 1.5
Answer:
η₁ = 2.6
Explanation:
Here, we will use snell's law to calculate the refractive of the substance:
[tex]\frac{\eta_2}{\eta_1} = \frac{Sin\theta_1}{Sin\theta_2}[/tex]
where,
η₁ = refractive index of first substance = ?
η₂ = refractive index of second substance = 1.5
θ₁ = angle of incidence = 30°
θ₂ = angle of refraction = 60°
Therefore,
[tex]\frac{1.5}{\eta_1} = \frac{Sin\ 30^0}{Sin\ 60^0}[/tex]
η₁ = 2.6

Answer:
This is one of the hottest summers America has ever seen and Jeremiah Warren is taking advantage of the heat wave and doing a little cooking…in his car!
It was about 98 or 99 degrees in Texas, so Jeremiah thought he’d head outside to see if it was hot enough to actually cook food. He buttered up a frying pan on his dashboard and filled it with an egg, cookie dough, a hot dog and bacon (mmm…bacon!). He set up another frying pan on the sidewalk and a few hours later he came back for a mid-day snack.

Differentiate the between, Heat, Thermal Energy, and Temperature.
Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat deals with the flow of thermal energy. Temperature is the physical manifestation of thermal energy, and deals with whether it feels cold or hot.

a 200 L of water tank is filled from a reason the inlet pipe at the bottom electrical overflow pipe prices with colourful the bottom boats 50 50 cm in diameter how much does the water rise in the overflow pipe in the water is heated from 10 degrees Celsius to 40 degrees Celsius
Answer:
The water rises by 4.45 m
Explanation:
Mass is constant
Mass = Volume /Specific Volume
Mass = 200/(1*10^-3*1.001) = 199.8 Kg
Volume after heating = specific volume * mass
= 1.008 *10^-3 lt/gm * 199800 gm
= 201.398 t
Change in volume = 1.3986
(pi)r^2 *h = 1.3986 *10^-3 m^3
3.14 * (1*10^-2 m)^2 *h = 1.3986 *10^-3 m^3
H = 4.45 m
A truck with a mass of 15,000 kg moving at 25 m/s crashes into the back of a small 1,100 kg car moving at 15 m/s. They
stick together after the collision. Calculate the momentum of the system before the collision and after the collision.
Explanation:
Given that,
Mass of a truck = 15,000 kg
Speed of the truck = 25 m/s
Mass of car = 1,100 kg
Speed of the car = 15 m/s
As they stick together after the collision. Let V be the speed after the collision.
Initial momentum of the system,
[tex]P_i=15000\times25+1100\times15\\\\=391500\ kg-m/s[/tex]
Final momentum of the system,
[tex]P_f=(15000+1100)V\\\\=16100V[/tex]
Hence, this is the required solution.

An ideal gas triples in volume in an adiabatic process. the initial pressure is 1.4 x 10^5 Pa. what is the final pressure? let y = 1.67.
5.8 x 10^4 Pa
2.2 x 10^4 Pa
1.4 x 10^4 Pa
1.0 x 10^5 Pa
Answer: 2.2x10^4
Explanation: in a adiabatic process pV^y = constant.
So V2=3V1 and p2 = p1 / 3^1.67 = 2.2x10^4 Pa

A 12.0 volt battery is connected in a series to 4 identical 5.00 ohm resistors connected in parallel to each other. What is the current through the battery?
Answer:
9.6 Amperes
Explanation:
since the resistors are connected in parallel connection the equivalent resistance is1/R = 1 /5 + 1/5 + 1/5 + 1/5
solving for R we get 5/4 ohms
then from V=IR
I = V/R
I=12/(5/4)
hence I= 9.6 Amperes
A 12.0-volt battery is connected in a series, then the current through the battery is 9.6 A.
What are Resistors?Electrical resistance is implemented as a circuit element by resistors, which are passive two-terminal electrical components. Resistors are devices that are used in electronic circuits for a variety of purposes, including lowering current flow, adjusting signal levels, dividing voltages, biasing active components, and terminating transmission lines.
As part of motor controllers, power distribution systems, or as test loads for generators, high-power resistors that can dissipate many watts of electrical energy as heat may be used.
According to the question,
1/R = 1 /5 + 1/5 + 1/5 + 1/5
R = 5/4 ohms
By ohm's law,
V=IR
I = V/R
I=12/(5/4)
I= 9.6 Amperes
