Answer: A salt
Explanation:
The reaction of Acids with most metals and, when they do, a salt is produced without water. Unlike the reaction between acids and bases, we do not get water.
Answer:
E = 5.5 10² N /C
Explanation:
For this exercise let's use Newton's second law
F = m a
the force is electric
F = q E
we substitute
q E = m a
E = 
(1)
the acceleration can be found with kinematics,
v = v₀ + a t
as the particle starts from rest v₀ = 0
a = v / t
a = 160 / 2.90
a = 55.17 m / s²
the relationship
q / m = 0.100 C / kg
m / q = 10 kg / C
we use equation 1
E = 10 55.17
E = 551.7 N / C
E = 5.517 10² N / C
ask for the result with two significant figures
E = 5.5 10² N /C
Answer:
solar wind
Explanation:
the sun's atmosphere is made of hydrogen which itself made subatomic particle. These particle are constantly boiling off the sun and streaming outward at very speed. So, the sun's magnetic field and particles are called solar wind.
B. Reflection is when waves bounce off a surface Ik this because I did it in 7th grade was my favorite unit to learn in school
Answer:
1. An object in motion will stay in motion: A car, and its breaks.
2. Force = mass x acceleration: Kicking a ball.
3. Equal or Opposite reaction: Tugging on your dogs leash as hes trying to run off.
