What is negative acceleration called? The other name of negative acceleration is Retardation or Deceleration. A deceleration is opposite to the acceleration. The deceleration means the decrease in the speed of body/object movement. What is negative acceleration in simple words? According to our principle, when an object is slowing down, the acceleration is in the […]
What is the direction of the electric field in the rod?
What is the direction of the electric field in the rod? The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. Since electric field is a vector quantity, it can be represented by a […]
What organs are part of the cardiorespiratory system?
What organs are part of the cardiorespiratory system? The cardiorespiratory system consists of the heart and blood vessels, which work with the respiratory system (the lungs and airways). These body systems carry oxygen to the muscles and organs of the body, and remove waste products, including carbon dioxide. Is 30 minutes of cardio 3 times […]
What is the relationship between molecular motion and pressure?
What is the relationship between molecular motion and pressure? The greater the molecular motion, the greater the pressure the molecules exert. What is heat in terms of molecular motion? Molecules are in constant motion and so they possess kinetic energy. Molecules at a higher temperature have more kinetic energy i.e. they move faster. Heat is […]
What is a matrix material?
What is a matrix material? The matrix is basically a homogeneous and monolithic material in which a fiber system of a composite is embedded. It is completely continuous. The matrix provides a medium for binding and holding reinforcements together into a solid. What is the benefit of composite matrix? Advantages of Composite Materials Low cost […]
Does the Earth revolve around the sun once a year?
Can a translation undo a reflection?
Can a translation undo a reflection? No. The translation followed by a reflection would put a figure in a different location in the plane when compared to the same reflection followed by the same translation. Summarize, or have students summarize, the lesson. We can sequence rigid motions. What does translation do to an image? Translation […]
What will make an object move in a circular path?
What will make an object move in a circular path? A centripetal force is a net force that acts on an object to keep it moving along a circular path. The tension force in the string of a swinging tethered ball and the gravitational force keeping a satellite in orbit are both examples of centripetal […]
What are the major causes of freshwater pollution?
What are the major causes of freshwater pollution? Pollution may be caused by fecal waste, chemicals, pesticides, petroleum, sediment, or even heated discharges. Polluted rivers and lakes are unfit for swimming or fishing; polluted water is unsafe to drink. How does water use impact the environment? Less Water Affects the Environment When reservoir water levels […]
