What percent of patients who have PTSD never fully recover? All told, 44 percent of the participants in all of the studies recovered from their condition and no longer qualified for a PTSD diagnosis. Can you recover from trauma without therapy? Trauma is considered to be a disconnective disorder, which means it does not typically […]

How much energy does it take to boil 100 mls of water if room temperature is 20c? From the steam tables, the heat capacity is close to 2 KJ/kg/deg C, far from 1.2 that you used, so it takes around 160 KJ to heat a kg of water to 100 C, from 20 C. This […]

What is the direction of induced current in metal rings 1 and 2 when current I in the wire is decreasing steadily? Predict the direction of induced current in metal rings 1 and 2 when current I in the wire is steadily decreasing . Solution : Metal ring 1 is clockwise. Metal ring 2 is […]

What will be energy to remove an electron from the ground state of u91 +? The energy required to remove both electrons from the Helium atom in its ground state is 79.0 eV. The energy required to remove both electrons from He in its ground state leaving behind He++ ion = 79 eV. … How […]

What is the use of geyser at home? A water geyser requires a lot of energy to heat water. This high consumption of electricity shoots up the electricity bill during winters. Therefore in order to lower the monthly electricity bills, it is very important to use water geysers in a right way. Can we drink […]

What is disadvantage of infrared thermometer? Infrared thermometers cannot take measurements of gas or liquids. The environment needs to be clean, without dust, high humidity, or similar. Depending on the model, the accuracy can be marginal. What is side effect of infrared thermometer? After testing a widely marketed forehead scanner made by Exergen, researchers at […]

How do you find a slope of a volume? To find the volume of the sloped area use the formula: the square of c = the square of a + the square of b (where c is the length of the slope, a is the depth. How do you calculate excavation volume and slope? The […]

Why does each element have a unique emission spectrum? As each element has different energy states available to it, each element releases photons of different color when its atoms return to their lower energy states. Since each atom has many excited states (high energy levels) available to it, several colors of light can be emitted […]

Is being assertive good or bad? Assertive behavior has respect at the very core of all communication – aggressive behavior has ego at the very core of well… everything. Assertive behavior is focused with a high listening acuity – aggressive behavior interrupts more than listens. What happens when you are not assertive? When people are […]

What is TCP header size? Specifies the size of the TCP header in 32-bit words. The minimum size header is 5 words and the maximum is 15 words thus giving the minimum size of 20 bytes and maximum of 60 bytes, allowing for up to 40 bytes of options in the header. What does a […]
