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

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

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.

The acceleration due to gravity on the Moon's surface is known to be about one-sixth of the acceleration due to gravity on the Earth.
A rock falls under a gravitational force of 16.3 N on the moon.
Please help me figure out the mass of the rock.
Answers
Answer:
The mass of the rock is approximately 9.97 kg
Explanation:
From the question, we have;
The acceleration due to gravity on the Moon = (1/6) × The acceleration due to gravity on the Earth
The gravitational force under which a rock falls on the Moon = 16.3 N
The acceleration due to gravity on Earth, g ≈ 9.81 m/s²
Therefore, the acceleration due to gravity on the Moon, a = (1/6) × 9.81 m/s² ≈ 1.635 m/s²
The relationship between the force with which the rock falls and the acceleration of the motion resulting in the force is given by the following relationship;
F = m × a
Where;
F = The force = 16.3 N
m = The mass of the object acted on by the force = The mass of the rock
a = The acceleration of the motion of the object = 1.635 m/s²
From F = m × a, we have;
m = F/a
∴ m = 16.3 N/(1.635 m/s²) = 9.96941896 kg
The mass of the rock, m ≈ 9.97 kg.

Imagine you leave the dock on a fishing boat that travels east for 30 kilometers when the captain realizes he left the fishing rods on the dock. It takes him 40 minutes to travel out against the current but only 20 minutes to return to the dock.
Answers
Answer:
Average speed is 60 km/hr whereas average velocity is 0 km/ hr.
Explanation:
The average speed of the boat is 60 km/ hr while on the other hand, the average velocity of the boat is 0 km/ hr because average speed is the total distance covered by the boat in total time and average velocity is the displacement covered by the boat in total time. The total distance covered by the boat is 60 km and the total time is 60 minutes which is equals to one hour so the answer is 60 km/hr whereas the displacement is the shortest distance between initial and final position which is 0 in this case so 0 divided by 60 minutes or one hour is also 0.
