A. True
Solid substances can indeed exist in more than one form, a phenomenon known as "allotropy" or "polymorphism." In allotropy, the same element or compound can have different crystal structures or arrangements of atoms in the solid state, resulting in distinct physical properties.
Common examples include carbon, which can exist as both diamond and graphite, and sulfur, which has multiple crystalline forms. These different forms of solids can have different properties, such as hardness, density, and electrical conductivity, even though they are made up of the same chemical elements.
A. thumb in the direction of the electromagnetic force.
B. forefinger in the direction of the motion.
C. forefinger in the direction of the lines of force.
D. thumb in the direction of the magnetic flux.
Correct answer choice is:
C. forefinger in the direction of the lines of force.
Explanation:
The direction of the force - and consequently the transfer of the wire - can be defined by applying Fleming’s left-hand rule.
The forefinger tends to the direction of the magnetic field. The middle finger points in the course of the current. The thumb supplies the direction of force or movement working on the conductor. Fleming's Left Hand Rule is applied in electronic engines which are utilized in coolers, appliances, printers, etc.
Answer: If one billiard ball hits another, the second will move with the same force as the first.
A child wants to jump to climb a tree (reaction), he must push the ground to propel himself (action).
A man deflates a balloon; the force with which the air comes out causes the balloon to move from one side to the other.
Explanation:
-Hitting A Wall
-Rowing a boat
-Walking
Explanation:
1.If you hit a Wall with your hands or legs, you get hurt. Why?
Because of Newton's Third Law. You hit the wall with a force and that exact same amount of force is returned by the wall.
2. While Rowing a boat, when you want to move forward on a boat, you paddle by pushing the water backwards, causing you to move forward.
3.While Walking, You push the floor or the surface you are walking on with your toes, And the surface pushes your legs up, helping you to lift your legs up.
the other answer is wrong, the answer is A. 0 joules for plato users, i got 100 on the test
B. less energy
C. more mass
D. more speed
Answer:
less energy
Explanation:
an electron near the nucleus has less energy than an electron farther away because the closer the electron orbit is to the nucleus, the lower the energy level and therefore the lower the potential energy it possesses . when electrons move farther away, they move unto higher energy orbitals and therefore gain more energy.
