As the speed of airplane is change due to jet stream
So the net speed is given as
now we can rearrange it as
now by the formula of vector difference we have
now plug in all values
so above is the speed of the plane
Answer:
a material with a large specific heat can absorb a great deal of thermal energy without a great change in temperature.
Explanation:
The specific heat capacity of an object is the amount of energy needed to raise the temperature of 1 kg of mass of a substance by .
Mathematically, it is given by:
where
Q is the amount of energy supplied
m is the mass of the substance
is the change in temperature of the substance
The equation can be rewritten as:
Therefore, we see that the increase in temperature of a substance is inversely proportional to its specific heat capacity.
Therefore, a material with a large specific heat can absorb a great deal of thermal energy without a great change in temperature.
Answer:
From Faraday's law of Induction: A changing magnetic field induces emf in the coil.
Explanation:
<u>Faraday's law</u> states that when a coil is run through a changing magnetic field or a magnet is passed back and forth through a coil, a<u>n emf is induced which produces electric current in the coil. </u>
Changing magnetic flux induces electromotive force.
When the magnet is passed back and forth, it causes a changing magnetic flux around the coil. This induces emf and the current flows which lights up the bulb connected to it.
To solve this problem, it is necessary to apply the ideal Gas equations, as well as the calculation equations of the weight difference, which under the comparison of two values.
By definition we know that the ideal gas equation is given by the equation,
PV = nRT
Where,
P = Pressure
V = Volume
R = Gas ideal constant
T = Temperature
n = number of moles
Our values are given by
PART A) Using this previous equation we can find the number of moles per Volume, that is
Replacing with our values
PART B ) We can calculate the number of moles of 1m^3 through Avogadro number, then
Therefore in there are 1.1524Kg of Gas.
PART C ) Density can be defined as the proportion of mass in a specific quantity of Volume, then
The difference of percentage then is
YES, because as the percentage is less than 10%, the calculated value agrees with the stated value.
