Answer:
8684.2 kg/m³
Explanation:
Tension in the rope as a result of the weight = 8.86 N
Tension in the rope when submerge in water = 7.84
upthrust = 8.86 - 7.84 =1.02 N = mass of water displaced × acceleration due to gravity
Mass of water displaced = 1.02 / 9.81 = 0.104 kg
density of water = mass of water / volume of water
make volume subject of the formula
volume of water displaced = mass / density ( 1000) = 0.104 / 1000 = 0.000104 m³
volume of the object = volume of water displaced
density of the object = mass of the object / volume of the object = (8.86 / 9.81) / 0.000104 = 0.9032 / 0.000104 = 8684.2 kg/m³
Answer:
A. Energy
Explanation:
You can change energy from one form to another when you lift your arm or take a step. Energy is used to move matter. In this scenario, the matter would be you.
As kinetic energy and temperature increase, Mass decreases and particle speed increases
Answer:
3.4 s is the correct answer to the given question .
Explanation:
As Given in the question
Vox=310 m/s
Voy=26 m/s.
As we know that
--------------eq(1)
As the velocity at the maximum height =0
Putting the value of in the equation(1) we get
Putting the value in the previous equation we get
Therefore h=3.4 s
