What is latent heat ?The quantity of heat (in joules or calories) per mole or unit mass of the substance undergoing a change in state is the typical way to represent latent heat.
The latent heat involved in melting solids or freezing liquids is referred to as the "heat of fusion," while the latent heat involved in vaporizing solids or liquids or condensing vapor is referred to as the "heat of vaporization."
When water boils at 100°C and turns into steam, water vaporizes into steam by absorbing heat of vaporization. This heat energy remains in the steam as kinetic energy and makes their movement fast.
So, The molecules will have more space between them and will be moving at higher speeds as steam compare to water.

Answer:
adolescence:)
Explanation:
Adolescence is the developmental period during which a person will experience the most amount of physical change. So, the correct option is B.
What is meant by periods of development ?The periods of development of a person is defined as the period of time or the stages of life during which the person grows up from an infant to an adult.
Here,
The developmental period of humans includes the different stages of their life such as infancy, early childhood, middle childhood, adolescence, early adulthood, middle adulthood and old age.
Adolescence is an important developmental period of a person that results in the more amount of physical changes in their body.
The physical changes that are occurring inside and out of the body during the period of adolescence is known as puberty. This happens due to the release and variations of some hormones in our body.
The physical changes that happens to our body during adolescence includes the change in body structure and shape, formation of facial hair and pubic hair, change in voice, etc.
During puberty stage, a hormone called testosterone or male hormone is released in boys.
A hormone called estrogen is released during puberty in girls.
These hormonal actions causes the various physical changes in the body.
Hence,
Adolescence is the developmental period during which a person will experience the most amount of physical change.

A 21.2-kg object is being pulled in one direction by a force of 68.8 N while a force of 26.5 N pulls in the opposite direction. What is the acceleration of the object
The net force is in the direction of the larger force. If we take that direction to be positive, then the net force has a magnitude of
68.8 N - 26.5 N = 42.3 N
Use Newton's second law to solve for the acceleration:
F = m a
42.3 N = (21.2 kg) a
a = (42.3 N) / (21.2 kg)
a ≈ 2.00 m/s²
(you might also try 1.99 or 2.01 in case that doesn't get accepted)

What is a vector quantity ?
A vector quantity is defined as the physical quantity that has both directions as well as magnitude.
if object is describing direction also , then it should be a vector quantity as it can not be scaler . Position , speed , motion all are scaler quantities
Along with direction it is also showing its distance , that means it must be displacement because When a body moves from one position to another, the shortest(straight line) distance between the initial position and final position of the body is known as its displacement and it is vector quantity .

Tanya randhawa is standing on top of a train that is traveling at 7 km/sec. The train hits a cow and comes to a complete stop. There is no gravity or friction in Tanyas world. According to newton's first law what happens to tanya
Answer:
Since there is no gravity or friction in Tanya's world, according to Newton's first law she will keep moving at a constant speed.
Explanation:
Newton's First Law, or also called the Law of Inertia, postulates that every body that is not subjected to any interaction (free or isolated body) remains at rest or moves with constant speed. In other words, it is not possible for a body to change its initial state (whether of rest or motion) unless one or more forces intervene.
In this law then the net force (Σ F) applied on a body is equal to zero and explains that to modify the state of motion of a body it is necessary to act on it.

A 200kg car is coasting to the right and slowing down due to a friction force of 200N.
By Newton's second law, the net force on the car is
∑ F = m a
where m is the mass of the car and a is magnitude of the acceleration.
The car is slowing down, so the net force opposes the direction in which the car is moving. Vertically, the car is in equilibrium, the net force is entirely due to friction. Taking the direction opposite the car's motion to be negative, we have
- 200 N = (200 kg) (-a)
a = (200 kg) / (200 N)
a = 1 m/s²
If you're also supposed to find the coefficient of kinetic friction, use the fact that the car the vertical forces cancel out, namely
n + (-w) = 0
where n is the magnitude of the normal force and w is the car's weight. The friction force f is proportional to the normal force n by a factor of µ, the coefficient of kinetic friction, such that f = µ n. Then
f / µ = w
(200 N) / µ = (200 kg) (9.80 m/s²)
µ = (200 N) / ((200 kg) (9.80 m/s²))
µ ≈ 0.102

Somebody pls help me with this question!
Answer:
speed are different at different places
Explanation:
because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other

Which shows the correct angle of reflection given the incident ray shown?
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Rays of light.
Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.
Thus Option c.) is correct.
C.) is the Answer.
The angle of reflection given the incident ray from the given diagrams is option C.
What is the refraction of light?When a light ray strikes the shining surfaces, the part of the light gets refracted. The bouncing back of the light is called reflection. When the light strikes the surface is called an incident ray.
When the light ray incident on the surface, the light returns back to the same medium is called reflection. The laws of reflection are, the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal takes place in the same plane. The speed of light remains the same in the process of reflection.
The reflected light ray changes the path of direction in the same medium. When a light ray enters from one medium to another, the speed of light gets decreases.
Thus, the ideal solution is option C.
