Answer 1

Answer:

1. Pascal's law was that if any pressure is applied to a fluid inside a closed system, then it will transmit that pressure equally in all the directions throughout the fluid. This law may be explained with an example of how pascals law is sometimes used in hydraulic power in heavy construction machines.
2. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquid..

Answer 2

Answer:

put me as Brainlist answer

Explanation:

What is Noise?

Noise is unwanted sound. A sound which has unpleasant effects and discomfort to ears is called noise. 

We can reduce noise Pollution by following below mentioned Tips:

• Turn off Appliances at Home and offices
• Shut the Door when using noisy Machines
• Use Earplugs
• Lower the volume
• Stay away from Noisy area
• Follow the Limits of Noise level
• Control Noise level near sensitive areas
• Go Green by planning trees
• Create Healthy noise to eliminate unwanted noise
• Use Noise absorbents in noisy machineries
• Use Proper Lubrication and Better maintenance
• Regularly check noise levels
• Notify Authorities about Disobedience of Noise Rules.
