Explanation

"6.022 × 10²³ atoms of carbon"

Correct — Each CO₂ molecule contains 1 carbon atom

So, 1 mole of CO₂ has 6.022 × 10²³ carbon atoms

Explanation

Free movements responding to external stimuli are called tactic movements (or taxis).

Tactic movements are directional responses

Where an organism moves toward or away from a stimulus, such as light (phototaxis) or chemicals (chemotaxis)

Explanation

The formula of electric field intensity is E= f/q

where F = force and q = small test charge

The electric field intensity at any point is the strength of the electric field at the point.

It is defined as the force experienced by the unit positive charge placed at that point

Explanation

"Blueshift" is a term that astronomers use to describe an object that is moving toward another object or toward us.

Someone will say, "That galaxy is blueshifted with respect to the Milky Way",

for example. It means that the galaxy is moving toward our point in space

Explanation

The SI unit of force is the newton, symbol N.

Explanation

 The endometrium is the inner lining of the uterus, and this is where a fertilized embryo implants to begin pregnancy.

Explanation

The waves in which the particles of the medium travel in the same direction as the waves, are longitudinal waves.

Longitudinal waves are waves in which the individual particles of the medium move in a direction parallel to the direction of propagation of the disturbance.

Explanation

The IUPAC name of acetone is propanone or propan-2-one.

It is also known as 2-propanone. 

Explanation

• V=f/λ is an expression that holds good for wave velocity
• ***
• The wave velocity of a wave is given by v=fλ 
• ****
• lambda = refers to the wavelength, the distance between the crests in meters (m)
• v = refers to the velocity of the speed of waves moving in a direction in meters per second (m/s)
• f = refers to the frequency, the wave crests that go through a point in certain time cycles per second or hertz (cycles/s or Hz)
