Answer:

Option B

Tile is a good conductor : a carpet is a good insulator

Explanation:

When the feet comes in contact with the tile, the tile conducts heat from the body making one to feel cold. However, since carpet is made of insulators such as cotton, they don't conduct heat, therefore, it slows down the flow of the heat which would make it feel warm so our feet do not feel much more colder as it does with the tiles.

Answer:

B) Tile is a good conductor : a carpet is a good insulator

Explanation:

Heat travels from hot to cold. Your feet are warmer than the tile. The tile is a conductor and when you step on it, heat from your body transfers to the tile making it feel cool.

A car has a mass of 1600 kg. It is stuck in the snow and is being pulled out by a cable that applies a force of 7560 N due north

sergiy2304 [10]

Answer:

Acceleration of the car will be $a=0.1375m/sec^2$

Explanation:

We have given mass of the ball m = 1600 kg

Force in north direction F= 7560 N

Resistance force which opposes the movement of car $F_R=7340N$

So net force on the car $F_{net}=F-F_R=7560-7340=220N$

According to second law of motion we know that F=ma

So $220=1600\times a$

$a=0.1375m/sec^2$

Atmospheric pressure varies from day to day. The level of a floating ship on a high-pressure day is (a) higher (b) lower, or (c)

frez [133]

Answer:

Explanation:

The force acting on the ship when it floats in water is the buoyant force. According to the Archimedes' principle: The magnitude of buoyant force acting on the body of the object is equal to the volume displaced by the object.

Thus, Buoyant forces are a volume phenomenon and is determined by the volume of the fluid displaced.

<u>Whether it is a high pressure day or a low pressure day, the level of the floating ship is unaffected because the increased or decreased pressure at the all the points of the water and the ship and there will be no change in the volume of the water displaced by the ship.</u>
