Answer:
Electronegative atom will create a stronger negative charge is true.
Explanation:
Given that,
Electronegativity affects the strength of intermolecular forces.
We know that,
Electronegativity :
Electronegativity is a ability of an atom, shared electron to itself.
In periodic table,
When we move left to right in period then the electronegativity increases.
When we move up to down in a group then the electronegativity decreases.
We know that,
The intermolecular forces are dipole-dipole interactions which is the strongest intermolecular force of attraction.
If the electronegativity of atom is more, then the atom gain negative charge.
When the attraction force is more in atoms then the electronegative will be more.
Hence, Electronegative atom will create a stronger negative charge is true.
Answer:
Density = 3 kg/m³
Explanation:
Given the following data;
Volume = 3m³
Mass = 9 kg
To find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the formula;
Substituting into the formula, we have;
Density = 3 kg/m³
Answer:
a) Δx ≈ 8.4 m
b) v ≈ 6.1 m/s
Explanation:
Given:
v₀ = 1.5 m/s
a = 2.1 m/s²
t = 2.2 s
a) Find: Δx
Δx = v₀ t + ½ at²
Δx = (1.5 m/s) (2.2 s) + ½ (2.1 m/s²) (2.2 s)²
Δx ≈ 8.4 m
b) Find: v
v = at + v₀
v = (2.1 m/s²) (2.2 s) + (1.5 m/s)
v ≈ 6.1 m/s
Answer:
water can be used as displacement to calculate the volume of a solid object.
<span>You can use one or more of your five senses to make observations during an inquiry activity.
we have nervous system which has special sensory system, we have sensory organs and senses, the five senses are touch, smell, hearing, sight and taste. every sense is related to an organ, like we can touch with hands, hear with ears, sight is related to eyes, we can smell with nose and taste with tongue.
