The horizontal motion of a launched projectile affects its vertical motion.

Physics
1 answer:
Talja [164]3 years ago

The horizontal motion of a launched projectile affects its vertical motion is false

Answer: False

<u>Explanation: </u>

As the trajectory falls on a plane, all the components like displacement, velocity can be classified in two components termed as horizontal and vertical component.

In a projectile motion, the horizontal components of displacement and velocity remains constant and there is change only in the vertical component of displacement and velocity.

Both components are not dependent to each other. So, the horizontal motions of a launched projectile does not affect its vertical motion.

Which state will not change shape or volume when moved to a different container?
grandymaker [24]

Ans: C) Solid

Explanation: We will look into different states

A) Liquid : In liquid state molecules are not very tightly bound to each other. So, they have no fixed shape . They take the shape of container in which they are kept.

B) Gas : In gaseous state molecules are very loosely bound so they have very less intermolecular forces so they have much more freedom of movement.So, it will be also not correct.

D) Plasma : In Plasma state approximately equal amount of positive or negative charges are there, although its a type of hot ionized gaseous state but but due its different properties then other gases it is considered the 'fourth' state. And it also can't maintain it's definite shape and volume.So we will eliminate that also.

C) Solid : Finally we are left with solid state. Here molecules are tightly bound to each other . So, it doesn't change its shape and volume when kept in different container.

So 'Solid' state is the correct choice.

Hope it helps!!!

In cloud formation, water vapor turns into water droplets which get bigger and bigger until it rains.
Andreas93 [3]

Basically there will be an increase in the air temperature in the clouds. Internally the water vapor is condensed in a cloud to fall like rain and release all the heat that it has inside. This heat is physically known as 'latent heat'. With this release of energy released as water vapor becomes drops of water, a microphysical process will be generated in the clouds that are responsible for controlling the conversion of water vapor into cloud particles and their respective rainfall.

The correct answer is A: Get Warmer.
