What is the acceleration at the highest point of a projectile? zero How do you find the horizontal component? To find the horizontal component, we multiply the magnitude of the vector by the cosine angle referenced to the horizontal. To find the vertical component, we do the same thing, but take the sine angle. What […]
What happens if gas pressure is too low?
How does heat and pressure affect rocks?
How does heat and pressure affect rocks? Igneous rocks form when rocks are heated to the melting point which forms magma. Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. What are the […]
What is vector quantity example?
What is vector quantity example? For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination. What is vector short answer? A vector is a quantity or phenomenon […]
What is the main function of neurotransmitters?
What is the main function of neurotransmitters? Neurotransmitters are often referred to as the body’s chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles. Communication between two neurons happens in the synaptic cleft (the small gap between the synapses of neurons). What are […]
Do all countries have 4 seasons?
Do you insulate hot or cold water pipes?
Do you insulate hot or cold water pipes? When preventing freezing is the goal, insulate both the hot- and cold-water pipes. Hot water pipes can also freeze unless water is actively running through them. If the goal is to lower water-heating costs, then it’s wise to insulate hot water pipes wherever you have access to […]
Are protons positive or negative?
Are protons positive or negative? Protons and Electrons A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain. […]
How do Wedge make work easier?
How do Wedge make work easier? A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance. This gives the wedge a mechanical advantage greater than 1. What is the difference between a wedge and a screw? Wedges generally concentrate force, usually to split […]
How did Hulk get his power?
How did Hulk get his power? Dr. Bruce Banner lives a life caught between the soft-spoken scientist he’s always been and the uncontrollable green monster powered by his rage. Exposed to heavy doses of gamma radiation, scientist Bruce Banner transforms into the mean, green rage machine called the Hulk. Can science make a real spider […]
