• what happens to the energy transferred to an object if it does not change its speed

• Energy is transferred from one object to ANOTHER when a reaction takes place. Energy comes in MANY forms and can be transferred from one object to another as heat, light, or MOTION, to name a few.
• This energy would be in the FORM of motion, with the person lifting the blue ball to a higher level.

ACRYLIC fibers are produced by two basic methods of spinning (extrusion), dry and wet. In the dry spinning method, material to be spun is dissolved is a SOLVENT. After extrusion through the spinneret, the solvent is evaporated, PRODUCING CONTINUOUS filaments which LATER may be cut into staple, if desired.

rong>Question:-

A stone is thrown vertically upwards with velocity of 49 m/s calculate the total time taken by the to REACH the surface of earth.

Solution:-

Given,

• stone thrown vertically upwards with a velocity of 49 m/s.
• Then calculate the time taken by the stone to reach ground.

We have to use SECOND equation of motion to find the time:-

u = 49 m/s ; G = 9.8 m/s² ; v = 0 ; s = ?

➣ v² - u² = 2as

➣ 0 − (49)² = 2(−9.8)(s)      

➣ -2401 = -19.6 s

➣ s = 2401/19.6

➣ s = 122.5 m

➣ v = u + at

➣ 0=49 − 9.8 t      

➣ t = 5 sec

∴ Total time taken by the stone to return to the surface of the ground is T = 2T = 10s

Newton's second law states that the ACCELERATION of an object is directly related to the net force and inversely related to its MASS. ... So, the force/mass ratio (from the equation acceleration = force/mass) is the same for each.

Pressure at the same depth is equal and it transmitted in all directions. This proof is conducted after considering Pascal's law holds true i.e. pressure exerted by any point in the fluid is equal in all directions. Pressure directly depends on height and for equal height a particular fluid exerts equal pressure.

Explanation : As we know the Density = mass / volume.

Here mass of SUBSTANCE is 10 gm and volume of water displaced by the substance us 5 ml ( The density of water is 1 gm/cc).

Formula for density is =

Density = mass / volume

Density of substance = 10/ 5

HENCE density of substance is 2

4.Scalars are quantities that are fully described by a magnitude (or NUMERICAL value) alone. Vectors are quantities that are fully described by both a magnitude and a directions

5.Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and WATER waves.

Social changes in adolescence

Identity

YOUNG people are busy working out who they are and where they fit in the world. You MIGHT notice your child trying out new things like clothing styles, music, art or friendship groups. Friends, family, media, culture and more shape your child’s choices in these years.

Independence

Your child will probably want more independence about things like how he gets to places, how he spends his time, who he spends time with, and what he spends money on. As your child becomes more independent, it’ll probably mean some changes in your family routines and relationships, as well as your child’s friendships.

Responsibility

Your child might be keen to take on more responsibility both at home and at school. This could include things like cooking dinner once a week or being on the school council.

New experiences

Your child is likely to look for new experiences, including risky experiences. This is normal as your child explores her own LIMITS and abilities, as well as the boundaries you set. She also needs to express herself as an individual.

But because of how teenage brains develop, your child might sometimes STRUGGLE with thinking through consequences and risks before he tries something new.

Values

This is the time your child starts to develop a stronger individual set of values and morals. She’ll question more things, and she’s also learning that she’s responsible for her own actions, decisions and consequences. Your words and actions help shape your child’s sense of ‘right’ and ‘wrong’.

Influences

Your child’s friends and peers might influence your child, particularly his behaviour, appearance, interests, sense of self and self-esteem. You still have a big influence on long-term things like your child’s career choices, values and morals.

Sexual identity

Your child might start to have romantic relationships or go on ‘dates’. But these aren’t always intimate relationships. For some young people, intimate or sexual relationships don’t occur until later on in life.

Media

The internet, mobile phones and social media can influence how your child communicates with friends and learns about the world.

EMOTIONAL changes in adolescence

Moods and feelings

Your child might show strong feelings and intense emotions, and her moods might seem unpredictable. These emotional ups and downs can lead to increased conflict. They happen partly because your child’s brain is still learning how to control and express emotions in a grown-up way.

Sensitivity to others

As your child gets older, he’ll get better at reading and understanding other people’s emotions. But while your child is developing these skills, he can sometimes misread facial expressions or body language.

Self-consciousness

Teenage self-esteem is often affected by appearance – or by how teenagers think they look. As your child develops, she might feel self-conscious about her physical appearance. She might also compare her body with those of friends and peers.
