What do we call a ramp and ladder combined? A wedge is a simple machine that is made of two inclined planes together. Inclined planes don’t move, but wedges do. An axe is an example of a wedge. Inclined planes are simple machines used to make work easier. Ramps, ladders, and staircases are all inclined […]
What is the main cause of ozone depletion?
What is the main cause of ozone depletion? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity. Is inhaling ozone bad? Whether in its pure […]
What is CP and CV for water?
What is CP and CV for water? Specific heat is the energy required to raise the temperature of a unit mass of a substance by one degree. In thermodynamics, there are two kinds of specific heats: Cv (specific heat at constant volume) and Cp (specific heat at constant pressure). What is CP and CV? The […]
Why is gravity a non-contact force?
Why is gravity a non-contact force? Magnetism is an example of a non-contact or action-at-a-distance force. These are forces which can act on an object without being in physical contact with it. The force of gravity is another example. Thus, gravity will pull a raindrop down to Earth without any tangible physical link between the […]
When a device is used in a circuit in which the voltage is 81V?
What are the six main structures of the central nervous system?
What are the six main structures of the central nervous system? These include structures such as the frontal and temporal lobes, the thalamus, the cerebellum, the putamen, mamillary bodies and fornix, and a convolution above the corpus callosum known as the cingulate gyrus. What are the different types of neurons of the central nervous system? […]
What is chemical energy for kid?
What is chemical energy for kid? Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place. What is chemical energy 7th grade? chemical energy: Energy that is stored in the chemical bonds of molecules. This energy is released during chemical […]
What are the possible values of n and ML for an electron in a 4 d orbital?
What are three factors that affect the flow of current in a circuit?
What are three factors that affect the flow of current in a circuit? Answer. Answer: Voltage, resistance, and whether the circuit is wired in series or parallel. The current in a circuit depends on the applied voltage and the resistance of the circuit. Why do we say current flows from positive to negative? The direction […]
