Answer:
It’s mass would be the same
Explanation:
Mass and weight are often used interchangeably in everyday conversation. For example, our medical records often show our weight in kilograms but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of Earth on an object. It depends on the distance from the center of Earth. Unlike weight, mass does not vary with location. The mass of an object is the same on Earth, in orbit, or on the surface of the Moon.
Answer:
Explanation:
We can use the equation for the speed
where x is the distance and t the time. In this case we know that the time spent was 2 hours and the distance was 150km. By replacing we have

Answer :
The time is 0.46 sec.
Explanation:
Given that,
Diameter = 0.30 mm
Voltage = 1.5 V
Length = 5.5 cm
Resistivity of gold
We know that,
The resistance is
...(I)
The current is
...(II)
Put the value of R
We need to calculate the drift velocity
Using formula of drift velocity
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time is 0.46 sec.
The sugar cube experiment in the laboratory gives us a good approximation of the amount of energy that can be derived from the sugar cube because the amount of energy is neither created or destroyed, it is just converted to another form. If the energy from the sugar cube is converted to other form in the lab then, it is possible that same amount of energy will be derived.
