Answer:
Because of the strong interaction of photons with matter,neutrinos rarely interact with matter
Explanation:
In the core of the sun,nuclear fusion which is a nuclear reaction,produces the photons and neutrinos,for photons to emerge from the sun's core it passes through denser particles colliding and losing energy as it moves at such it can take it up to a million years to emerge from the sun core.Unlike the neutrinos that has more easier path,with little or no collission.
Answer:
I am the bloopy blap blap man do u know english
Explanation:
Givens:




Let t=2 be the final velocity. Since Velocity stays the same horizontal , acceleration due to gravity changes the vertical direction
Use this equation

Plug in the knowns


So the velocity in the y direction at 2 seconds is -10.57
The velocity in the x direction at 2 seconds is 11.97
Use the Pythagorean theorem to find the total velocity


b. The range at which it strike the ground.
We need to find when the velocity at the top is zero.
Using the y direction,


Next, find the height of the max.

So the total distance is 4.16+20= 24.16
Next to find the total time it falls


So our total flight time is

Range is
