Answer: 20 pm=20*10^-12 m
Explanation: To solve this problem we have to use the relationship given by:
λmin=h*c/e*ΔV= 1240/60000 eV=20 pm
this expression is related with the bremsstrahlung radiation when a flux of energetic electrons are strongly stopped hitting to a catode. The electrons give their kinetic energy to the atoms of the catode.
Answer:

We’re are the answer choice at ?
Answer:
Zero.
Explanation:
In the general projectile motion there is only one component of acceleration which is in the vertical direction.There is no any acceleration in the horizontal direction.As we know that horizontal component of the velocity is remains constant in the projectile motion.
Therefore we cans say that in the projectile motion ,the acceleration in the horizontal direction is zero.
Therefore the answer will be zero.
So whats the question
sorry if i failed to make it out
and
you typed that all in!!!
