Answer:
2.44 m/s due East
Explanation:
From the question given above, the following data were obtained:
Mass of 1st car (m₁) = 4 Kg
Velocity of 1st car (u₁) = 3 m/s
Mass of 2nd car (m₂) = 5 Kg
Velocity of 2nd car (u₂) = 2 m/s
Final velocity (v) =?
The final velocity can be obtained as follow:
v(m₁ + m₂) = m₁u₁ + m₂u₂
v(4 + 5) = (4×3) + (5×2)
9v = 12 + 10
9v = 22
Divide both side by 9
v = 22/9
v = 2.44 m/s
Thus, the final velocity is 2.44 m/s.
Since both cars was moving due East before collision, and after collision, they stick together, then their direction will be due East.
Its really hurts
Explanation:
Charge A and charge B are 2.2 m apart. Charge A is 1.0 C, and charge B is
2.0 C. Charge C, which is 2.0 C, is located between them and is in
electrostatic equilibrium. How far from charge A is charge C?
The temperature scale which starts at absolute zero is the Kelvin scale. The correct option in respect to the given question is the last option. William Thompson was the British scientist and inventor that invented the Kelvin scale. William Thompson was also popularly known as Lord Kelvin.His discovery of the Kelvin scale is considered one among the three best scales in use for measuring temperatures.Each measuring unit of this scale is never called a degree but a Kelvin. This specialized scale gives the option of measuring temperature in both centigrade and Fahrenheit.
The answer should be C) Slide against each other.
