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
Answers
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

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.
Answers
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.

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.
Answers
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.
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?
Answers
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

A spring of force constant 1500 Nm-l is acted
upon by a constant force of 75 N. Calculate
the potential energy stored in the spring.
Answers
Answer:
1.876 J
Explanation:
First, let’s calculate the compression of the spring from the Hooke’s law:
F=kx,
here, F=75 N is the force acted on the spring, k=1500 N⁄m is the force constant of the spring, x is the compression of the spring.
Then, we get:
x=F/k=(75 N)/(1500 N/m)=0.05 m.
Finally, we can find the potential energy stored in the spring:
PE=1/2 kx^2=1/2∙1500 N/m∙(0.05 m)^2=1.875 J.
correct my answer if it's wrong ^^

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
Answers
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

A plane is flying with an airspeed of 190 miles per hour and heading 150°. The wind currents are running at 30 miles per hour at 170° clockwise from due north. Use vectors to find the true course and ground speed of the plane. (Round your answers to the nearest ten for the speed and to the nearest whole number for the angle.)
Answers
Answer:
[tex]Vg=200mile/hr[/tex]
[tex]\theta=153 \textdegree[/tex]
Explanation:
From the question we are told that:
Plane airspeed [tex]v_p=190mil/h[/tex]
Plane direction [tex]\angle=150 \textdegree[/tex]
Wind current speed [tex]V_w=30mil/h[/tex]
Wind direction [tex]\angle=150 \textdegree[/tex]
Generally the vector form of the forces is mathematically given by
For plane
[tex]\angle Q_p=90-150 \textdegree[/tex]
[tex]V_p=170(cos60 \textdegree ,sin60 \textdegree)[/tex]
[tex]V_p=(85,-147.224)[/tex]
For wind
[tex]\angle Q_w=90-170 \textdegree[/tex]
[tex]V_w=30(cos-80 \textdegree ,sin-80 \textdegree)[/tex]
[tex]V_w=(5.2,-29.54)[/tex]
Generally the equation for resultant force is mathematically given by
[tex]v_r=V_a+V_w[/tex]
[tex]v_r=(85,-147.224)+(5.2,-29.54)[/tex]
[tex]v_r=(90.21,-176.76)[/tex]
[tex]v_r=198.45\angle -63[/tex]
Therefore ground speed
[tex]V_g=198.5miles/hr[/tex]
[tex]Vg=200mile/hr[/tex]
Direction
[tex]\theta=(90+63)=153 \textdegree[/tex]
[tex]\theta=153 \textdegree[/tex]
