Answer:
Ballistic is along the bottom
Answer:
18m/s
Explanation:
Given parameters;
Initial velocity = 10m/s
Acceleration = 2m/s²
Time = 4s
Unknown:
Car's new velocity = ?
Solution:
We use one of the kinematics equation to solve this problem:
v = u + at
v = new velocity
u = initial velocity
a = acceleration
t = time
v = 10 + (2 x 4) = 18m/s
The answer is group 1A.
In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.
Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.
Hence, X must belong to the 1A group.
Ionic Compounds-
- Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
- Cations are positively charged ions that are formed due to the loss of electrons.
- And the anions are negatively charged ions that are formed due to the gain of electrons.
- Due to this, they have opposite charges and form bonds known as Ionic Bond.
