Answer:
An object in motion stays in motion, in a uniform motion, unless acted on by an external unbalanced force.
Explanation:
This statement is also known as Newton's First Law of motion (also called "Law of inertia").
It states that:
"When an object is in motion at constant velocity (or at rest), the object tends to remain in its state of motion at constant velocity (or at rest), unless there is a net external unbalanced force acting on it".
The action of an external unbalanced force would change the state of motion of the object; in particular, it will cause an acceleration in the object, according to Newton's Second Law of motion:
where
F is the net force on the object
m is the mass of the object
a is its acceleration
Therefore, we can see that if the external force acting on the object is zero:
F = 0
Then the acceleration of the object is also zero:
a = 0
And so, the object will continue its motion with constant velocity (or it will remain at rest, if it was at rest).
Answer:
electrons move causing the object to be positive or negative charged
Wave speed = frequency * wavelength
Rearrange so it's equal to wavelength. Do this by diving both sides by frequency to leave you with:
Wave speed / frequency = wavelength
340 / 265 = 1.2830 m
Answer:
The work done on the box is 80 J.
Explanation:
Given that,
Weight of box = 40 N
Distance = 2 meter
We need to calculate the work done
Using formula of work done
Where, x = distance
mg = weight
Put the value into the formula
Hence, The work done on the box is 80 J.
Answer:
Volume.
Explanation:
Boyle’s law experiment :
This is also known as Mariotte's law or in the other words it is also known as Boyle–Mariotte law.
This law tell us about the variation of gas pressure when the volume of the gas changes at the constant temperature.According to this law the abslute pressure is inversely proportional to the volume .
We can say that
Where P=Pressure
V=Volume
PV = K
K=Constant
When volume decrease then the pressure of the gas will increase.
That is why the answer is "Volume".
