What are the uses of units in our daily life? Measurement provides a standard for every day things and processes. From weight, temperature, length even time is a measurement and it does play a very important role in our lives. The money or currency we use is also a measurement. And think of the rumble […]
Has a hurricane ever hit Mississippi?
Has a hurricane ever hit Mississippi? 1969: Hurricane Camille Hurricane Camille is one of just four Category 5 storms to make landfall in the continental United States, according to the National Weather Service. The storm made landfall near Waveland, Mississippi, in August 1969. Storm surge reached almost 25 feet in parts of Mississippi. What was […]
Why are light bulbs brighter in a parallel circuit?
Why are light bulbs brighter in a parallel circuit? When the bulbs are in parallel, each bulb sees the full voltage V so P=V2R. Since a bulb glows brighter when it gets more power the ones in parallel will glow brighter. See, the parallel combination of resistors reduces the effective resistance of the circuit. Hence […]
Is any closed conducting path?
Is any closed conducting path? There must be a closed conducting loop from the positive to the negative terminal in order to establish a circuit and to have a current. When this occurs, the circuit is opened and a closed conducting loop no longer exists. Without a closed conducting loop, there can be no circuit, […]
How big of a telescope do you need to see planets?
How big of a telescope do you need to see planets? Telescopes that have 4 or 5 inch diameters are great for viewing solar system objects like the planets, our Moon, and Jupiter’s moons. Viewing Neptune and Uranus can be difficult with a scope this small but it’s not impossible. A telescope of this size […]
What is the intensity for muscular endurance?
What is the intensity for muscular endurance? For experienced lifters who want to improve their muscular strength, aim for 8–12 reps per set for 2–4 sets, with a 2- to 3-minute rest between sets. To improve your muscular endurance, do 15–20 repetitions at no more than 50% of your 1RM, with a 2- to 3-minute […]
When two waves interfere destructively what changes?
When two waves interfere destructively what changes? This is known as destructive interference. In fact, if the two waves (with the same amplitude) are shifted by exactly half a wavelength when they merge together, then the crest of one wave will match up perfectly with the trough of the other wave, and they will cancel […]
Which solid has the highest melting point?
Which solid has the highest melting point? tungsten Do impurities lower melting point? The presence of even a small amount of impurity will lower a compound’s melting point by a few degrees and broaden the melting point temperature range. Because the impurity causes defects in the crystalline lattice, it is easier to overcome the intermolecular […]
What is the force acting on the ball?
What is the force acting on the ball? The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion. What is the action force acting on? […]
What rate is the length of the shadow changing?
What rate is the length of the shadow changing? We’ve determined the instantaneous rate of change in the position of the shadow, which is -160 ft/sec, but that figure changes dramatically as the bird moves closer to the ground (and the mouse). In which case the length of the shadow of the tree will be […]
