What causes all the objects to move? When a force pushes or pulls the object, the object will move in the direction of the force. Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a […]
What would happen if there was no sun for 24 hours?
What would happen if there was no sun for 24 hours? With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s […]
What are 3 characteristics of the mantle?
What are 3 characteristics of the mantle? It is mostly solid rock, but less viscous at tectonic plate boundaries and mantle plumes. Mantle rocks there are soft and able to move plastically (over the course of millions of years) at great depth and pressure. The transfer of heat and material in the mantle helps determine […]
What are the disadvantages of selective breeding?
What are the disadvantages of selective breeding? List of Disadvantages of Selective Breeding It can lead to loss of species variety. It does not have control over genetic mutations. It brings about discomfort to animals. It can create offspring with different traits. It could create a genetic depression. It poses some environmental risks. Why Selective […]
Why is pressure not proportional to volume if the temperature changes?
Why is pressure not proportional to volume if the temperature changes? Remember that the force of the collisions do not change unless the temperature changes. If the temperature of a gas stays the same, the pressure of the gas increases as the volume of its container decreases. What happens to volume if temperature increases? The […]
What are 3 physical changes?
What are 3 physical changes? Physical changes affect a substance’s physical properties but do not alter its chemical structure. Types of physical changes include boiling, clouding, dissolution, freezing, freeze-drying, frost, liquefaction, melting, smoke and vaporization. What is a physical change of matter? A physical change is a change to a sample of matter in which […]

Answer Expert Verified it’s quite dangerous to live in the pacific ring of fire knowing that countries in that area are more prone to earthquakes, volcanic eruptions, and tsunamis. You will be more exposed to natural calamities. so think twice before […]
Why do we need to avoid resonance?
Why do we need to avoid resonance? The natural frequency of a system is dependent upon two main factors; stiffness, and mass. If the natural frequency is above or significantly far away from any expected vibration frequencies the resonance will likely no be excited. This theory forms the basis for any structural redesigns implemented to […]
