An electric toy car with a mass of #2 kg# is powered by a motor with a voltage of #4 V# and a current supply of #1 A#. How long will it take for the toy car to accelerate from rest to #3 m/s#? …

Energy of the subshell ( orbitals) is decided by n+ l rule. Orbitals with a lower n + ℓ value are filled before those with higher n + ℓ values. In this context, n represents the principal quantum …

1 kWh is the amount of energy used by an appliance rated as 1 kW or 1000 W if it is used for 1 hour. 1 kWh = 3.6 * 10^6 J

Therefore, it would radiate energy and its final temperature would be 0K. From the gas equation PV=nRT, for T=0 we have PV=0. As the volume of the gas can't be zero,therefore, P=0. This …

As the diagram shows, 2 #CO_2# molecules are released when #isocitrate# is oxidized and subsequently decarboxylated. The first part of this 2 step process is aided by the enzyme …

Mar 1, 2016 · The negative sign indicates that the potential energy decreases by that much. The sign makes sense because in attractive interactions the potential energy decreases if the …

We use the strong nuclear foce to heat up water in a nuclear reactor, making a turbine spin that's producing energy. We also use it in nuclear weapons like atom bombs. It's also found in stars …

The Earth's magnetic field is constant however the lines of magnetism are swept back by CMEs(Coronal Mass Ejection). The figure above illustrates the Earth's magnetic field during a …

+"133 kJ/mol" The idea here is that you need to use the change in Gibbs free energy, DeltaG^@, and the change in entropy, DeltaS^@, of the reaction at 161.0^@"C" to determine the change …

How much energy, in joules, is released by an earthquake of magnitude 8? What are the 3 main types of seismic waves? How do they differ from each other? What are waves produced by …
