What is required is force on the inside of the lid of the box that is greater than the force of air pressure on the outside of the lid.

What is inside an empty box?

Air, unless it is an airtight box.


Does the box slide if the coefficient of friction of the box on the table is 0.4 with a horizontal force of100N acting on a 20kg box?

F=0.4(n) where f is force required to move box form resting (static) position and n is the normal force applied by the surface of the table. So F=.4x20kg=8kg. 8kg are required to overcome resisting force due to friction. 8kg=Appox. 78N. 78N of force is required to overcome resisting force due to friction.


If a force is required to pull a 20 kg box across a carpeted floor what is typically true about another force required to pull the box across the ice at a rink?

Pulling a box across ice requires less force than pushing the same box across carpet. This is due to the amount of friction between the carpet and box and the lack of friction between the ice and the box.


Why force required to move box of same weight changes in case of different surfaces in contact?

Force required to move a box of the same weight changes in the case of different surfaces in contact due to friction.


How much force is required to hold a 12 kg box off the ground?

The force required to hold a 12 kg box off the ground would be equal to the weight of the box, which is calculated by multiplying the mass by the acceleration due to gravity (9.8 m/s^2). Therefore, the force required would be approximately 117.6 newtons.


What force is needed to accelerate a box with a mass of 5 kg to an acceleration of 3 ms2?

The force required is 15 Newtons.


A force of 320 N is required to pull a box across the floor at a constant velocity What is the force of friction between the floor and the box?

It's 320 N. Since the friction force is in the direction opposite to the motion, thepulling force and the friction force balance, the net horizontal force on the box iszero, and its speed is therefore constant.


How many joules are required to push a box 10 meters with a force of 5 N?

A joule is a neuton metre. i.e. 10*5 = 50 joules are required.


A force of 20 N is required to lift a box the box is lifted from the floor to a shelf that is 2 m high the amount of work done is?

Work Done= Force applied x distance moved in direction of the force. so the work done should in this case be 40J


How do you make a sound proof box?

you could make it airtight or put lots of matresses on the walls


What is the work being done to slide the box if a box is weighing 345N and is being pushed up an inclined plane that is 3m long A force of 275 is required including friction?

Please use the formula: work = force x distance


How do you remove air filter box Volvo s60?

To remove the top cover you need to losen the clips around the box. there are 5 or 6 clips. push them in the middle with force, then they will come off. and the bottom part of the box you must take off the fresh air intake that comes from the radiator. just pull it out. And the bottom box itself sits in 3 rubber parts. pull the box agaist the engine. to the right of the car. must use force here as well.
