Answer:
C) 100 joules
Explanation:
The kinetic energy of an object is given by:

where m is the mass of the object and v its speed.
In this problem, we have an object of mass m = 50 kg and v = 2 m/s, so by using the formula we can find its kinetic energy:

C because it’s not a or B so 50/50 c or d and d is def not the answer so c
Switch because look A switch detects the speed that given device can handle and communicates with it at that speed
34. The element would have 34 protons. Also 34 electrons.
