Baking a cake would be a chemical change because the baking powder/soda undergoes through a reaction, you can tell because it generates bubbles/bumps when you bake it.
A chemical change is also irreversible so when you bake the cake, you cannot separate the ingredients.
So your answer would be B. Baking a cake
Hope this helps !

Answer:
a) 6.028*10^10 m/s^2
b)2.156*10^-5 s
c)14.01 m
Explanation:
Hello!
I will not consider relativistic efects since the velocity of the proton is 1% of the velocity of ligth.
In order to find the acceleration we need to calculate first the force, this is done by multiplying the electric field times the charge of the proton (1e=1.6*10^-19)
Since the mass of the proton is 1.6726219 × 10^-27 kilograms
The acceleration it suffers due to the electric field is:
Since the proton accelerates from rest, the velocity as a function of time is given by:
So
Finally, the length traveled by the proton in that interval is given by:
D.) Asteroids
Asteroids are large rocks that orbit the sun. They aren't considered planets since they are smaller.
