Answer:
Any material that exerts magnetic force is considered a magnet.
The given statement is True.
Explanation:
Material that exerts magnetic force is a magnet.
- Whatever material exerts magnetic force, that is supposed to call a magnet.
- Alike all distinct forces, a magnetic force implies a gravitational force.
- The area within the poles of a magnet has the most powerful effect and the magnets attract wood and materials that contain iron.

Answer:
Distance = 72 meters.
Explanation:
Given data:
speed of burrito = 4 meter/ second
Time taken in flight = 18 seconds.
Required: The distance covered during this time and having the above speed by the burrito.
Solution :
Formula of speed is given below.
Speed = distance / time interval
By putting the values of speed and time, we get,
4 meter / second = distance / 18 seconds.
Multiply 18 both, we get
4 x 18 = distance
Distance = 72 meters.

It's in group 1, so its outershell only has 1 electron, and the other shells are completely filled, so 2 then 8. :)
Answer:
(a) 5.04; (b) 5.18; (c) 12.30
Explanation:
(a) pH of buffer
HA + H₂O ⇌ H₃O⁺ + A⁻
(b) pH after addition of base
HA + H₂O ⇌ H₃O⁺ + A⁻
I/mol: 0.1 0 0.2
C/mol: -0.02 +x +0.02
E/mol: 0.08 x 0.22
(c) pH of water after addition of base
pOH} = -log0.02 = 1.70
pH = 14.00 - pOH = 14.00 - 1.70 = 12.30
