Tas watches as his uncle changes a flat tire on a car. his uncle raises the car using a machine called a jack. each time his uncle pushes down on the jack handle, the car rises up. tas sketches the jack and labels it using the symbols f, to represent force, and d, to represent distance. he uses large and small letters to compare the sizes of the forces and distances.

which set of labels is correct for the side of the jack that tas’s uncle pushes on?

a-a large f and a small d
b-a small f and a small d
c-a large f and a large d
d-a small f and a large d

D) -a small F and a large d

Explanation:

As per Pascal's law we know that the pressure applied to any point of the fluid is equally transmitted to all points of the fluid.

So here we can say that when we apply some pressure at the input point then that pressure will be equally transmitted to all points

So here we have

so here in order to have large output force we can say

so we need to apply smaller force so that we will get bigger value of the distance that the jack will move upwards.

so correct answer will be

D)-a small F and a large d

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
