What volume of silver metal will weigh exactly 2500.0 g. The density of silver is 10.5 g/cm³
Answers
Answer:
Explanation:
Density = mass/volume
132g/(48.9 cm³) = 2.7 g/cm³
(27 g)/(3 cm³) = 9 g/cm³
512 g/(65 cm³) = 7.9 g/cm³
1.2 kg/(3243 cm³) cm³ = 1200 g/(3243 cm³) = 0.37 g/cm³

The mass of water in the kettle is 0.50 kg. The specific heat capacity of water is 4200 J/kg °C. The initial temperature of the water is 100 °C. Calculate the average power output from the water in the kettle to the surroundings in 2 hours
Answers
Answer:
1.27 Mega watt approx
Explanation:
Given data
Mass= 0.5kg
c= 4200 J/kg °C
T1= 100°C
Time = 2 hours >>>> 7200 seconds
From the given data the water is already at the boiling point
Hence if continuous heat is being added the latent heat of vapourization will result, the latent heat of vaporization is about 2,260 kJ/kg
Q= mL
Q= 0.5*2,260
Q = 1130kJ
Power= Energy * Time
Power= 1130* 1130
Power= 1.27mega watt approx

Explain why gaps are left between railway lines
Answers
Answer:
to prevent the derailing of the train due to thermal expansion.
Answer:
Iron are good conductors of heat and electricity. Being a good conductor it expands as well as contracts with the change of temperature.When heat is applied,they expands because molecules inside the element gets excited and number of molecules inside it increases in tremendous amount,so it leads to expansion of iron. So when the temperature is lowered it comes in its normal state.
The term for this is called as thermal expansion or contraction.The gap in the joint between 2 rails is to prevent from the expansion of the iron. It is necessary ,if not there will be change in structure,it may buckle and chance of derailed is increased.
Explanation:
The gap in the joint between to rails is to compensate for the expansion of the material of rail during summer.
The metals expand or contract with the changes in temperature. The expansion or contraction depends on the coefficient of thermal expansion of the material. Based on this property of the metal, the gap in the joint of two rails is provided.

1 watt is the same as the transfer of ____
joules per second. What number completes the sentence?
Answers
Answer:
1 watt is the same as the transfer of 1 joules per second.
1 watt is the same as the transfer of energy at a rate of 1 joule per second.
A watt is a unit of power, representing the amount of energy transferred or converted per unit of time. Specifically, 1 watt is equivalent to 1 joule of energy being transferred every second. It is a common metric used to measure the rate of energy flow or work done in various systems. For example, a 100-watt light bulb converts electrical energy into light and heat at a rate of 100 joules per second. Understanding power in terms of watts helps us quantify and compare the efficiency and performance of different devices and processes.

Between steel and iron which is more suitable for making permanent magnets electromagnet and magnetic screen give reason for your answer
Answers
Answer:
steel is suitable for making permanent magnet
as still has hi factor coercity.
iron is for electromagnet and magnetic screen as iron loses its magnetism as soon as the switch is open and a current is switched off.
Steel is better suitable for making permanent magnets than soft iron since it has higher retentivity and lower coercivity. Compared to soft iron, steel has a lower retentivity and higher coercivity. Compared to soft iron, steel is more resilient and coercive.
What is retentivity and coercivity ?Retentivity : The ability to retain the generated magnetization in a magnetic material when the magnetizing force is removedCoercivity : A measure of the ability of a material to withstand an external magnetic field without becoming demagnetized.What is Permanent magnet and Electromagnet?Permanent magnet : To be suitable for permanent magnet, material should retain its magnetism for longer time, since steel have high retentivity and coercivity . Electromagnet : To be suitable for electromagnet , material should have magnetization and demagnetizing property .
Since , steels have high remanence which means it will remain magnetized even after magnetic field is removed which is not suitable for electromagnetic . iron has high permeability so magnetization is larger and have low retentivity so that material will not retain the magnetic properties . Magnetic screen , Iron has high permeability hence it can shield better than steel

State the Law of Electric Charges in your own words.
Answers
[tex] \\ [/tex]
According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
Things that are negatively charged and things that are positively charged pull on (attract) each other. This makes electrons and protons stick together to form atoms. Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.
