Answer:
yea it seems pretty simple.... just follow the instruction
P= 10m = 10 x 180 = 1800 N
work is done by the weightlifter in lifting the barbells :
A= Ph = 1800 x 1.95 = 3510 J
ok done. Thank to me :>

Answer:
Note that while calcium hydroxide, barium hydroxide, and strontium hydroxide are strong bases, they are not very soluble in water.
...
Examples of Strong Bases.
Base Formula Ions
sodium hydroxide NaOH Na+(aq) + OH-(aq)
potassium hydroxide KOH K+(aq) + OH-(aq)
lithium hydroxide LiOH Li+(aq) + OH-(aq)
The time taken for the first p-wave to reach the same seismic station is approximately 13 minutes.
<h3>Time of travel of the P-wave</h3>
In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
<h3>Relationship between speed and time</h3>
v ∝ 1/t
v₁t₁ = v₂t₂
t₁/t₂ = v₂/v₁
t₁/t₂ = 0.6v₁/v₁
t₁/t₂ = 0.6
t₁ = 0.6t₂
t₁ = 0.6 x 22 mins
t₁ = 13.2 mins
Thus, the time taken for the first p-wave to reach the same seismic station is approximately 13 minutes.
