Answer:
Explanation:
Velocity of a wave is describe as
velocity =Frequency × Wavelength
Mathematically
v = fλ
Hence, Frequency, F = v / λ
Wavelength λ = v/f
So, if the frequency is kept constant, wavelength of the wave becomes directly proportional to velocity of the wave.
And this implies that, as the speed double, the wavelength is double.
True
The half-life isn’t applicable to a first order reaction because it does not rely on the concentration of reactant present. However the 2nd order reaction is dependent on the concentration of the reactant present.
The relationship between the half life and the reactant is an inverse one.
The half life is usually reduced or shortened with an increase in the concentration and vice versa.
It had a gravitational force that acts so that it pulls Earth in an orbital, which explains temperature variations throughout the years.
Explanation:
When bullet is shot towards the monkey then let say the distance of monkey from the bullet is "d"
so we can find the time to reach the bullet to the monkey

Now similarly we can find the vertical displacement of the bullet in the same time


so it is given as

here if the monkey is initially at height H above the ground at given angle then we can say

so we can say that

So if at the same time monkey will fall down then the height of monkey from ground after time "t" is given as

so here bullet will hit the monkey as both monkey and bullet are at same position.
