Answer (4)
Some of these frictions depend on the Pressure, temperature of atmosphere.
Static Friction: This is the friction force when two objects in contact are not moving relative to each other. This friction is higher than kinetic friction.
Kinetic or Dynamic friction: this the friction force opposing the motion of objects, when two objects in contact are in motion relative to each other. It is less than the static friction. The two surfaces are rubbing against each other as they move.
Rolling friction: This is the friction when two objects are in contact and one object is rolling over the other - like a wheel on a road. The point of contact appears as stationary. The rolling friction is very less compared to static friction & dynamic friction.
Lubricated friction: this is the friction between two solid surfaces in contact with a layer of lubricant fluid flowing in between them. This friction is the least.
Fluid friction - viscosity : this is friction between two adjacent layers that are moving relative to each other at different speeds in a fluid. This is not high.
Internal friction: when an object is compressed and forced to deform, like in a piece of rubber, there is friction between the layers, that opposes this deformation.
Skin friction is the friction that opposes movement of a fluid across a solid surface. This is also called drag. When a coin is dropped in water, there is a friction called drag on the coin. Same is the case when a ball is thrown, a drag is experienced by the ball due to the drag of air.
Friction is the force that opposes the relative motion or tendency of such motion of two surfaces in contact. There are four types of friction: static friction, sliding friction, rolling friction, and fluid friction. ;
Friction opposes motion between surfaces and comes in four types: static, sliding, rolling, and fluid friction. Static friction prevents motion when objects are at rest, while sliding friction occurs when objects move past each other. Rolling friction happens when an object rolls, and fluid friction occurs when an object moves through a liquid or gas.

Jawaban:Berikut adalah letak astronomis dari negara-negara yang Anda sebutkan:- *Australia*: 10°41' LS - 43°39' LS dan 113°9' BT - 153°39' BT- *Brazil*: 5°16' LU - 33°45' LS dan 46°45' BB - 74°03' BB- *Belgia*: 49°30' LU - 51°30' LU dan 2°30' BT - 6°30' BT- *Swiss*: 45°49' LU - 47°48' LU dan 5°57' BT - 10°29' BT- *Belanda*: 50°45' LU - 53°45' LU dan 3°20' BT - 7°10' BT- *Korea Utara*: 37°40' LU - 43°00' LU dan 124°10' BT - 130°40' BT- *Jepang*: 20°25' LU - 45°30' LU dan 122°56' BT - 153°59' BT- *Argentina*: 23°00' LS - 55°00' LS dan 53°00' BB - 73°00' BB- *India*: 8°4' LU - 37°6' LU dan 68°7' BT - 97°25' BT- *Portugal*: 36°57' LU - 42°10' LU dan 9°30' BB - 0°30' BTMengenai luas letak astronomis, perlu diingat bahwa letak astronomis sendiri tidak memiliki luas karena hanya berupa garis lintang dan bujur. Namun, jika Anda ingin mengetahui luas wilayah masing-masing negara, berikut adalah luas wilayahnya:- *Australia*: 7.686.850 km²- *Brazil*: 8.514.877 km²- *Belgia*: 30.528 km²- *Swiss*: 41.290 km²- *Belanda*: 41.543 km²- *Korea Utara*: 120.538 km²- *Jepang*: 377.944 km²- *Argentina*: 2.780.400 km²- *India*: 3.287.263 km²- *Portugal*: 92.390 km²Jumlah luas wilayah negara-negara tersebut adalah sekitar 22.082.142 km².
