2. What is the mass of 2 kg of ice that melts when 400 000 cal is given to the ice? ( L = 800 cal / g )
Suhu & Kalor " Kalor "
Diketahui :
massa es keseluruhan : 2 kg
Q = 400 000 kalori
L = 800 kal/g
Ditanya : Massa es yang meleleh
Jawab :
[tex]Q_{Lebur} = m . L\\\\m = \frac{Q_{Lebur}}{L}\\\\m = \frac{400 000}{800}\\\\m = 500 g[/tex]
- massa yang meleleh = 500 gram
- massa yang tidak meleleh = 2 - 0,5 = 1,5 kg

5. 800 g of liquid X at 30°C is mixed with the same liquid of mass Mkg at 80°C. The final temperature after mixing is 60°C. What isvalue of M?#help me #physic
Penjelasan:
m.∆t1 = m.∆t2
800.(60°-30°) = m.(80°-60°)
800. 30° = m . 20°
m = 30°/20° x 800
m = 1200 g
6. 800+800= ? 200+200? 10 poin
800 + 800
= 8 + 8 ( 00 )
= 16 + 00
= 1.600
200 + 200
= 2 + 2 ( 00 )
= 4 + 00
= 400
[tex]{\colorbox{black}{\red{\boxed{\colorbox{black}{\red{ { \sf ☯︎ \: NamaKokAlvaro \: ☯︎}}}}}}}[/tex]

11. The maas of Ca(OH)² in 800 ml of Ca(OH)² solution with pH 12+ log 4 is....gram (Ar : Ca=40 O=16 , H=1)
diket :
Larutan Ca(OH)2
Mr Ca(OH)2 = Ca + O + H
= 40 + (2 x 16) + (2 x 1 )
= 40 + 32 + 2
= 74
v = 800 ml = 0,8 L
pH = 12 + log 4
pOH = 14 - (12 + log 4)
= 2 - log 4
[OH-] = 4 x 10^-2
[OH-] = b . Mb
4 x 10^-2 = 2 . Mb
Mb = 2 x 10^-2 = 0,02
M = n / v
0,02 = n / 0,8 lt
n = 0,02 x 0,8 mol
= 0,016 mol
n = massa / Mr
0,016 = massa / 74
massa = 0,016 x 74
= 1,184 gram

12. what is the net force on an 800 kg airplane flying with a constant velocity of 160 km/hour north
Jawaban:
Punten kak, izin menjawab yaa..
Penjelasan:
According to Newton's Law (ll)
F = m.a
Because base on the question above that plane's velocity is constant, so delta v or we called "acceleration" is zero "0".
So, value of F on Newton's Law (ll) as follow:
F = 800 × 0 = 0

19. A train of mass 800 000 kg is slowing down. What acceleration is produced if the braking force is 1 400 000 N
From task
we know :
mass = m = 800.000 kg
F = 1.400.000 N
Problem : acceleration?
solved :
a = F / m
= 1.400.000 / 800.000
= 1,75 m/s²
20. If an object has a mass of 8 kg moving at a speed of 10 m/s. the kinetic energy ( the object is… J A.400 B.800 C.80 D.40 Dengan cara ya
Jawaban:
400 J
Penjelasan:
The formula for kinetic energy:
Ek = [tex]\frac{1}{2}[/tex]mv²Ek = Kinetic Energy
m = mass
v = velocity
So, if the mass of the object is 8 kg, and it's moving at 10 m/s, then:
Ek = [tex]\frac{1}{2}[/tex] . 8kg . (10m/s)² = [tex]\frac{1}{2}[/tex] . 8kg . 100 m²/s² = 400 kgm²/s² = 400 JHence, the kinetic energy of the object is 400 J
