What else can I help you with?
The motion of giant wheel is a rotatory motion is true or false?
True. The motion of a giant wheel involves rotatory motion as the wheel spins around a central axis.
Particles that make up matter are in constant motion true or false?
True. The particles that make up matter are in constant motion due to their kinetic energy. This motion can vary in speed and direction depending on factors such as temperature and pressure.
Does Motion occurs when there is a change in speed true or false?
True. Motion occurs when an object changes its position relative to a reference point. A change in speed indicates a change in the rate of motion, which can result in the object moving at a different pace or direction.
True or false the motion of an object thrown at an angle is projectile motion?
True. Projectile motion describes the curved path an object follows when thrown or projected near the Earth's surface, under the influence of gravity, while also moving horizontally.
True or false A screw is a simple machine?
True. A screw is a simple machine that converts rotational motion into linear motion. It is typically used to hold objects together or lift loads.
Is it true that atoms in solids have motion?
Yes, atoms in solids do have motion known as vibrational motion. This motion occurs due to thermal energy, causing the atoms to vibrate in fixed positions. The extent of motion depends on factors such as temperature and the material's structure.
Why are some vibrational modes of benzene IR inactive?
Some vibrational modes of benzene involve a change in electric dipole moments. These are IR active modes. Some vibrational modes have no net change in dipole moment (which is true for most of the modes since benzene is a planar symmetrical molecule) when they stretch, so they are IR inactive. There are 30 vibrational modes for benzene altogether, 8 of which are IR active. Some vibrational modes of benzene involve a change in electric dipole moments. These are IR active modes.

Is it true Chemical properties aren't as easy to observe as physical properties?
Yes, physical are on the outside and can be observed in a matter of seconds, whereas chemical properties have to be tested, which can take as long as years
The motion of giant wheel is a rotatory motion is true or false?
True. The motion of a giant wheel involves rotatory motion as the wheel spins around a central axis.
Particles that make up matter are in constant motion true or false?
True. The particles that make up matter are in constant motion due to their kinetic energy. This motion can vary in speed and direction depending on factors such as temperature and pressure.
Is it true that the vertical motion of a projectile is uniformly accelerated motion?
Yes.
What do we say when the sun goes down over the horizon?
We say that it is 'setting,' but this is apparent motion, and not true motion. The same is true for the rising and setting of the moon and fixed stars. There is another spectacular example of apparent motion that is different from true motion. Because the moon 'rises' in the east and 'sets' in the west, it is easy to think that it is "moving" from east to west. In fact, the moon's orbit around the earth is from west to east. The slow (monthly) orbit of the moon along with the 24-hour rotation of the earth give us the impression of the moon's apparent motion.
True or false different kinds of motion can happen at different rates?
True.
Is it true that projectiles always have both horizontal and vertical motion?
true
Does Motion occurs when there is a change in speed true or false?
True. Motion occurs when an object changes its position relative to a reference point. A change in speed indicates a change in the rate of motion, which can result in the object moving at a different pace or direction.

Is true about the lithosphere plates?
They are constantly in motion.
