Answer:
NO
Explanation:
Acceleration is change in velocityΔv in respect to timeΔt
so if the velocity of the car is greater than the truck it does not mean that the car acceleration is greater than the truck.
Sometimes with constant velocity it means no accelaration ,but the truck may have accelaration
so, higher velocity of the car does not mean higher acceleration
Answer:
Negative acceleration occurs when the acceleration vector points to the left.
1. Object slowing down in the positive direction.
2. Object speeding up in the negative direction.
Following six statements:
1. T
2. F
3. T
4. T
5. F
6. T
Check direction of acceleration vector.
The atom that is the most electronegative is fluorine (F).

What is electronegative?</h3>
Electronegativity, is the tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond.
Electronegativity increases across the groups from left to right of the periodic table and decreases down the group.
Examples of electronegative elements arranged in decreasing order;
- fluorine,
- oxygen,
- nitrogen,
- chlorine,
- bromine,
- iodine,
- sulfur,
- carbon, and
- hydrogen.
Thus, the atom that is the most electronegative is fluorine (F).
