From the choices provided, the better answer is ' T ' .
To develop this problem it is necessary to apply the equations concerning the conservation of the moment.
By definition the moment can be expressed in two ways,
The first as a function of force and because of time, that is
And also based on mass and speed
Speed 1 is moving in the opposite direction to our reference system and it remains constant, as is the mass therefore
Equation both expression we have that,
Therefore the speed of the glider is 2m/s
Answer:
The answer is the Earth is tilted as the Earth makes its journey for the year around the Sun.
In general the earth is tilted at angle of 23.5 degrees from vertical axis. So that the Earth always pointing to one side as it revolves around the Sun. This causes varying amounts of Sun light around the Earth during the years gives us seasons.
So here we conclude that the axis of the Earth is most important thing, why the seasons occur.
Tilt:
Whenever the Earth lean towards the Sun, summer season occurs and lean away from the Sun winter season occurs. In between these two spring and Autumn occurs.
Answer:
- de Broglie wavelength of the bullet is 4.56 x 10⁻³⁴ m
- The value of the wavelength shows that wave nature of matter is insignificant for the bullet because it is larger than particles.
Explanation:
Given;
mass of the bullet, m = 1.9 g = 0.0019 kg
velocity of the bullet, v = 765 m/s
de Broglie wavelength of the bullet is given by;
where;
h is Planck's constant = 6.626 x 10⁻³⁴ J/s
λ is de Broglie wavelength of the bullet
Thus, this value of the wavelength shows that wave nature of matter is insignificant for the bullet because it is larger than particles.
