Answer;
= 4.49 g/cm³
Explanation;
Density = Mass / Volume
mass = 1.41 kg,
volume = 0.314 L
but; 1 kg = 1000 g and 1 L = 1000 mL
Thus;
Density = 1.41 kg/0.314L
Density = 4.49 kg/L (1000g/ 1kg)(1L/1000cm^3)
Density = 4.49 g/cm^3
Answer:
-414.96 N
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration


The force the ground exerts on the parachutist is -414.96 N
If the distance is shorter than 0.75 m then the acceleration will increase causing the force to increase
Answer:
d. The hammer falls with a constant acceleration
Explanation:
Since gravity is the only thing that is acting on the hammer as it falls and gravity is a form of acceleration then acceleration of 9.81m/s² which is gravity is the correct answer.
Answer:
Gram
Explanation:
Meter is a unit used to measure length and liter is used to measure liquids therefore using process of elimination the answer has to be gram
