What is the frequency of a pendulum vibration 40 times in 20 s? 2 Hz What is the time period of one oscillation? The time for one oscillation is the period T. The number of oscillations per unit time is the frequency f. These quantities are related by f=1T f = 1 T . What […]
In which case magnification is less than 1?
In which case magnification is less than 1? In a concave mirror, when the distance of the object is less than the focal length, the magnification will be greater than one. When the distance of the object is greater than the focal length, then the magnification is less than one. Can the magnification be less […]
Do you really need anti-static wrist strap?
Do you really need anti-static wrist strap? It is not vitally important to either your safety, or the safety of your computer’s electrical components that you use an anti-static strap / mat. That being said, it does not hurt anything at all to be using one, and it will definitely help to ensure that everything […]
Does the Firefly 2 plus get you high?
What has the strongest gravitational field?
What has the strongest gravitational field? Jupiter, the fifth planet from the Sun, has the strongest gravitational pull because it’s the biggest and most massive. Massive Gravitation. Jupiter and the Asteroid Belt. Almost a Star. Jupiter and Neighboring Planets. Who found the value of G? Henry Cavendish How would the value of G and G […]
How do you know if something is moving at constant velocity?
How do you know if something is moving at constant velocity? Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. You can also obtain an object’s velocity if you know its […]
Does friction decrease inertia?
Does friction decrease inertia? Overcoming Inertia Once an object starts moving, inertia keeps it moving without any additional force being applied. Friction opposes the motion of all moving objects, so—like the skateboard—all moving objects eventually stop moving even if no other forces oppose their motion. What is the importance of friction in our daily life? […]
What are the two formulas for refractive index?
What are the two formulas for refractive index? Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v. What is the relation between refractive index and thickness? Thus there is no general relation between refractive […]
Why does the CMB appear so uniform in all directions?
Why does the CMB appear so uniform in all directions? The problem is that, when we look up at the sky, and take a look at the microwave radiation (that’s the leftover radiation from the big bang), we find that it’s the same temperature, 2.725 Kelvin, in every direction. The motion of us against the […]
Which is true of the scientific method?
Which is true of the scientific method? Explanation: The scientific method can be described as the basic procedure through which all scientific researches are organized and it determines the accuracy of all scientific theories and researches. Hence, option A is correct. The scientific method starts with a question based on which a hypothesis is derived. […]
