Answer:
18.60 m/s
Explanation:
Original momentum = mv = 4000 with m = 115
after collision m = 115 + 100 = 215 kg
but the total momentum is still the same (conserved)
4000 = 215 v shows v = 18.60 m/s
Answer: Acceleration due to gravity
Explanation: Force, F = mg, is a vector quantity because the acceleration due to gravity, g, is a vector quantity. Explanation: F = mg Where m is the mass (in kilograms) of the object in question and g is the acceleration due to gravity. Mass is a scalar quantity; mass has no dependence on direction whatsoever.
Answer: C, supplements and drugs both undergo stringent government testing.

Answer:
True
Explanation:
The radio transmitter generates the radio frequency
As you move away from the radio transmitter, the radio frequency decreases
The relationship between frequency and wavelength is inverse
As the frequency decreases the wavelength of the radio signal increases
