Explanation:
When a solution is saturated it means, No more solute can dissolve in solvent
Answer:
0.25m/s
Explanation:
Given parameters
m₁ = 5kg
v₁ = 1.0m/s
m₂ = 15kg
v₂ = 0m/s
Unknown:
velocity after collision = ?
Solution:
Momentum before collision and after collision will be the same. For inelastic collision;
m₁v₁ + m₂v₂ = v(m₁ + m₂)
Insert parameters and solve for v;
5 x 1 + 15 x 0 = v (5 + 15 )
5 = 20v
v =
= 0.25m/s
Answer:
The ocean liner
Explanation:
Given that,
The mass of the bullet, m = 0.0014 Kg
The velocity of the bullet, v = 396 m/s
The mass of the ocean liner, M = 7.1 x 10⁷ Kg
The velocity of the ocean liner, V = 13 m/s
The kinetic energy is given by the formula,
K.E = 1/2 mv²
1) The kinetic energy of the bullet,
K.E = 1/2 x 0.0014 x 396²
= 109.775 J
2) The kinetic energy of the ocean liner,
K.E = 1/2 x 7.1 x 10⁷ x 13²
= 6 x 10⁹ J
Hence, the ocean liner has more kinetic energy.
Answer:
The current through the bulb is 0.5 Ampere.
Explanation:
Given:
Power = P = 60 watt
Voltage = V = 120 volts
To Find:
Current = I =?
Solution:
Power:
It is the product of Voltage and Current
Unit = watts
Formula


Complementary angles are those whose sum is 90 degrees, right?, then let's find A, A=72 degrees, because its mid point is 36 deg. Then, B = 18 degrees and its mid point is 9 degrees! :)
