Can the sign of the acceleration ever be positive for an object that is slowing down? According to our general principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object also has a positive acceleration. Is it true that acceleration only takes place when speeding […]
What activates and deactivates the electromagnet?
What activates and deactivates the electromagnet? Electromagnets Can Be Turned On and Off When the electrical current is active, the electromagnet produces a magnetic field. When it’s not active, the electromagnet doesn’t produce a magnetic field. After lifting the load and moving it to a different area, a worker may deactivate the electromagnet to release […]

Typical examples of pollutants included under this category are ash, smoke, fumes, dust, nitric oxide, sulphur dioxide, hydrocarbons etc. What are the major sources of pollutants? The […]
What is the strongest alloy?
What is the strongest alloy? Steel What are some examples of alloys? An alloy is a mixture or metallic-solid solution composed of two or more elements. Examples of alloys include materials such as brass, pewter, phosphor bronze, amalgam, and steel. What alloys do we use everyday? List of Alloys and Their Composition and Uses Name […]
What is a good example of instantaneous speed?
What is a good example of instantaneous speed? At a given instant time what we read from the speedometer is instantaneous speed. For example, a car moving with a constant speed travels to another city, it must stop at red lights in the traffic, or it should slow down when unwanted situations occur in the […]
How do you poop after hip surgery?
How do you poop after hip surgery? After surgery, you should also plan to take a stool softener, such as docusate (Colace). A fiber laxative, such as psyllium (Metamucil), may also be helpful. Purchase a laxative or stool softener before your surgery so that you have it available when you return home. Can you ever […]
What is the value of horizontal acceleration?
What is the value of horizontal acceleration? The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of […]
When atoms are bombarded with alpha particles only a few in million suffer deflection others pass out Undeflected This is because?
When atoms are bombarded with alpha particles only a few in million suffer deflection others pass out Undeflected This is because? When atoms are bombarded with alpha particles, only a few in millon suffer deflection, other pass out undeflected. This is because. The nucleus occupies much smaller volume compared to the volume of the atom. […]

What is a potential divider used for?
What is a potential divider used for? A potential divider is a simple circuit that uses resisters(or thermistors / LDR’s) to supply a variable potential difference. They can be used as audio volume controls, to control the temperature in a freezer or monitor changes in light in a room. Why do we need voltage? Electrical […]
