Answer:

acceleration m/s²

Explanation:

The units on the left side of the equation are units of length. The units on the right side of the equation must be units of length also. Acceleration times time squared gives length.

An electron in a tv picture tube is accelerated through a potential difference of 10 kv before it hits the screen. What is the k

fomenos

Answer:

10,000 eV

Explanation:

Due to the law of conservation of energy, the kinetic energy of the electron at the end of its path is equal to its initial electric potential energy, given by:

$U=q\Delta V$

where

q is the electron charge

$\Delta V$ is the potential difference

Here we have:

$q=1 e$ is the electron's charged

$\Delta V=10 kV=10,000 V$ is the potential difference

Substituting into the formula, we have

$U=(1e)(10,000 V)=10,000 eV$

How would you present weight change if earth had twice the mass that it does now

rosijanka [135]

Twice the mass means twice the acceleration due to gravity which will increase acceleration by the factor of 2 thus the weight will be double the time.
