causing the block to accelerate uniformly at
1.4 meters per second2 to the right. After the
skater stops pushing the block, it slides onto a
region of ice that is covered with a thin layer
of sand. The coefficient of kinetic friction
between the block and the sand-covered ice is
0.28.
On the diagram in your answer booklet, starting
at point A, draw a vector to represent the force
applied to the block by the skater. Begin the
vector at point A and use a scale of
1.0 centimeter = 5.0 newtons.
X - rays are considered an oxidizing mutagenic agent. X-rays are high energy electrons that can cause damage when exposed under extreme conditions. The best technology that can block it is t using a lightweight type of metal foam. It can take in high energy collisions which also exhibits high forces. it does not only block x-rays but also, neutron radiation and gamma rays.
Volume % = mole %
Molar mass of oxygen = 32kg/kmol
Molar mass of nitrogen = 28 kg/kmol
Density of nitrogen = Density of oxygen x molar mass of oxygen x molar ratio of air x molar mass of nitrogen
Density of nitrogen = (1.43kgm^-3)(1 kmol O2/32 kg O2)(80 kmol N2/ 20 kmol O2)(28 kg N2/1 kmol O2) = 5.01 kg/m3
Answer: The correct answer is force of gravity.
Explanation:
Gravity is the force with which one body attracts the other body.
It goes down a hill with the increase in the kinetic energy. The kinetic energy is due to the motion of a wagon.
At the hill the gravity is lesser in comparison to the gravity on the surface of the earth.
When a wagon rolls down a hill it speeds up. Here, the earth attracts the wagon with the force of gravity. It accelerates down a hill with an acceleration due to gravity.
