Why does a spoon in a glass of water look bent? A spoon half-immersed in a glass of water appears bent at the surface of the water. We know that this is due to refraction of light, which bends the rays of light at the surface, so that the retinal image of the spoon is […]

When a force is applied on a body it may change its? A force applied on an object can change its state of rest or motion and its shape or size. What are the three laws of motion class 9? In the first law, we come to understand that an object will not change its […]

What is temperature really a measure of? Temperature is a measure of the average kinetic energy of the particles in an object. When temperature increases, the motion of these particles also increases. It’s not a terrible definition, but it’s not the best either. What is the difference between temperature and energy? Thinking about the learning […]

How strong is tuff rock? Tuff rock has geotechnical properties such as 18-25 kN/m3 of unit weight, 1.5 – 2.4 gr/cm3 of bulk density, 2.29 – 2.64 gr/cm3 of particle density, highly varied compressive strength depending on the degree of weathering, 0 – 1.45 MPa of cohesion, friction angle = 24° – 45° of friction […]

How long does aspirin take to dissolve in water? After the Alka-Seltzer tablet was added to the hot water the tablet should have quickly dissolved, taking some 20 to 30 seconds to do so, depending on the exact temperature. Does aspirin dissolve water? Solubility. Aspirin is only slightly soluble in water and acidic solutions such […]
