Answer:
Solids
:A solid has a definite shape and volume because the molecules that make up the solid are packed closely together and move slowly. Solids are often crystalline; examples of crystalline solids include table salt, sugar, diamonds, and many other minerals. Solids are sometimes formed when liquids or gases are cooled; ice is an example of a cooled liquid which has become solid. Other examples of solids include wood, metal, and rock at room temperature. Liquids
: A liquid has a definite volume but takes the shape of its container. Examples of liquids include water and oil. Gases may liquefy when they cool, as is the case with water vapor. This occurs as the molecules in the gas slow down and lose energy. Solids may liquefy when they heat up; molten lava is an example of solid rock which has liquefied as a result of intense heat. Gases
: A gas has neither a definite volume nor a definite shape. Some gases can be seen and felt, while others are intangible for human beings. Examples of gases are air, oxygen, and helium. Earth's atmosphere is made up of gases including nitrogen, oxygen, and carbon dioxide. Plasma: Plasma has neither a definite volume nor a definite shape. Plasma often is seen in ionized gases, but it is distinct from a gas because it possesses unique properties. Free electrical charges (not bound to atoms or ions) cause the plasma to be electrically conductive. The plasma may be formed by heating and ionizing a gas. Examples of plasma include stars, lightning, fluorescent lights, and neon signs.
Explanation:
I think its d, it is pointing to the whole circle which prob rlly makes it a proton
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v
choice: D
Mechanical advantage may be greater than, less than, or equal to 1. Class 2: Resistance (or load) in the middle: the effort is applied on one side of the resistance and the fulcrum<span> is </span>located<span> on the other side, for example, a bottle opener or the brake pedal of a car. </span>
Power = (work done) / (time to do the work)
Work done = (force) / (distance moved in the direction of the force)
The work for the first mass is (5 kg) x (g) x (2 m) = 10g Joules.
The work for the 2nd mass is (10 kg) x (g) x (1 m) = 10g Joules.
as long as Jenna lifts both masses on the same planet, the amount of work is going to be the same in both cases. So in order to have the same power output, she would have to do both jobs in the same amount of time. If she did the first one in 3 seconds, then the second one also requires 3 seconds.
