-The water washes it causing it to break
-How hot or cold it is matters.
-ice can get into cracks which causes it to crack
-????
Explanation:
The species with a positive charge over it, which means lack of electrons are called cations. Whereas the species with negative over it, meaning it has an excess of electrons with it are called anions.
From the list given the cations are
H+, Ba2+, Hg2+, Li+, Ca2+ and Fe2+
Whereas anions from the list are
O-2, Br-5, F-, S-2.
A Combination of cation and anions make an ionic compound in which cation is written first and then anion.
Answer:
D.) It is between groups 13 to 18 because it is a non-metal.
Explanation:
Here we can see the periodic table and what each element is.
It is a non - metal because it is gaseous.
I think it's E. heating of water
Because exothermic process discharges heat, causing the temperature of the prompt environment to rise
Please correct me if I'm wrong!! I'd be happy to fix it!! :)
Answer:
Because of less weight kick ball has more acceleration.
Explanation:
Acceleration of kick ball:
5 m/s
Acceleration of soccer ball:
3 m/s
Newton's second law:
According to newton's second law the acceleration of object depends upon two variables.
1) Mass of object
2) Force acting on it
Mathematical expression:
a = f/m
a = acceleration
f = force
m = mass
The force on balls are same thus the acceleration is depend upon the masses of balls.
The soccer ball has more weight that's why its acceleration is less while kick ball is lighter and thus its acceleration will more.
