-- Two satellites at the same distance, different masses:
The forces of gravity between two objects are directly
proportional to the product of the objects' masses. In
other words, the gravitational forces between the Earth
and an object on its surface are proportional to the mass of
the object. In other words, people with more mass weigh more
on the Earth, and the Earth weighs more on them.
If the satellites are both at the same distance from Earth,
then the Earth pulls on the one with more mass with greater
force, and also the one with more mass pulls on the Earth
with greater force.
-- Two satellites with the same mass, at different distances:
The forces of gravity between two objects are inversely
proportional to the square of the distance between them.
In other words, the gravitational
forces between the Earth
and an object are inversely proportional
to the square of
the distance between the object and the center of the Earth.
If
the satellites both have the same mass, then the Earth
pulls on the nearer one with greater force, and also the
nearer one pulls on the Earth with greater force.
-- Resistor in a circuit when the voltage changes:
The resistance depends on how the resistor was manufactured.
Its resistance is marked on it, and doesn't change. It remains
the same whether the voltage changes, the current changes,
the time of day changes, the cost of oil changes, etc.
If you increase the voltage in the circuit where that resistor is
installed, the current through the resistor increases. If the current
remains constant, then you can be sure that somebody snuck over
to your circuit when you weren't looking, and they either installed
another resistor in series with the original one to make the total
resistance bigger, or else they snipped the original one out of the
circuit and quickly connected one with more resistance in its place.
The distance from the Earth to the Sun is 92.96 million mi.
The resistance of a wire is directly proportional to the length of the wire. That is the longer the length of the wire, the higher the resistance and the shorter the length of the wire, the smaller the resistance.
The reactions that are carried out on sugar within are body are very similar to the reaction of combustion. The reactants used and the product formed are the same in the aerobic respiration reaction. Therefore, it is possible to estimate the energy released by the sugar in the body by finding out the energy released when the sugar is burned. Despite the products arising from different pathways with different mechanisms, the reactants and products being the same means that the energy released will be similar.
Before entering the closed room, the cert members should assess
the situation first. They should gather information in order to determine if it’s
safe to go or if needed assistance to the current situation. They should consider some probabilities
before they establish the decision and take an action. Especially to the current situation where there is a possibility that the smoke that they smell is coming from the room and the reason may be because there is a fire. Assessing the situation before taking an action immediately is a must, in order to prevent further harm.
