Answer:
720,000
Explanation:
change in momentum = m (v2-v1)
= 45,000(258-242)= 720,000
<span>When the delta brainwave frequencies increase into the frequency of theta brainwaves,
active dreaming takes place and often becomes more experiential to the
person. Typically, when this occurs there is rapid eye movement, which
is characteristic of active dreaming. This is called REM, and is a well
known phenomenon.. Hope that helps!</span>
Answer:
The wavelength of the wave is tripled this can be done by reducing the frequency of the wave by factor of three.
Explanation :
The relation between the wavelength & frequency of a wave is given by
C = ν λ
Where
C - it is the velocity of light in vacuum.
ν - frequency of the wave.
λ - wavelength of the wave.
So we find that wavelength of a wave varies inversely with the frequency of a wave i.e. ν ∝ 1/λ.
Answer: Velocities are not equal
Explanation: A projectile usually have a given initial velocity, the velocity must be resolve into components of x and y with respect to the velocity of the projectile in a certain angle. In a projectile trajectory the final velocity for the y- component is always 0m/s since the object reaches its maximum point.
Answer:
Antarctic Circle
Explanation:
The Tropic of Cancer, which is also referred to as the Northern Tropic, is the most northerly circle of latitude on Earth at which the Sun can be directly overhead. This occurs on the June solstice, when the Northern Hemisphere is tilted toward the Sun to its maximum extent.
Tropic of Capricorn Is it Southern Hemisphere counterpart, marking the most southerly position at which the Sun can be directly overhead.
