Answer:
The more mechanical energy is lost in the transfer to other forms of energy, the less efficient the machine. Machines lose some energy in the form of heat due to friction. The more moving parts a machine has, the more energy it loses to friction because the parts rub together.
Color I believe because if a diamond was the same color as coal(black) you couldn’t tell a difference
Since pressure is force per unit area, blood pressure could be thought as the force exerted by the blood to the surface area of your blood vessels. When your blood vessels dilate, it means that they expanded. The result would be faster flow of blood. When this happens, the force of the blood is not any more concentrated on your blood vessels because there is more room available.
Think of a faucet where tap water flows. When you stopper the faucet with your finger, you feel the force of the water. The pressure builds up as manifested by the sound your faucet makes. But when you release your finger, the water rushes through and flows faster. The pressure is released. Therefore, when your blood vessels are dilated, your blood pressure decreases.
Answer:
Ionic bonding
Explanation:
In ionic bonding, electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.

The total net force acting on the rope is 120 because 300 - 180 = 120.
