Answer:

Bouyancy

Explanation:

Bouyancy occurs when the upthrust exerted on an object is equal to the weight of object displaced. It is mostly applicable to low density objects for example balloon. When balloon is displaced in water, it floats. This is due to the effect of the upthrust acting on the balloon which allows the balloon to float and which is opposite the weight.

Note that the weight acts downwards the object while the upthrust always acts opposite (upward)

A SPARK PLUG IN AN AUTOMOBILE ENGINE CONSISTS OF TWO
kirill [66]

Answer:

Electric potential, V=3.52\times 10^{12}\ volts

Explanation:

It is given that,

The magnitude of electric field, E=4.7\times 10^7\ V/m

Distance between automobile engines that consists of metal conductors, d = 0.75\ mm = 7.5\times 10^4\ m

Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:

V=E\times d

V=4.7\times 10^7\ V/m \times 7.5\times 10^4\ m

V=3.52\times 10^{12}\ volts

So, the magnitude of the potential difference between the conductors is 3.52\times 10^{12}\ volts. Hence, this is the required solution.

The work done in holding a 30kg of bricks to a height of 20m is
ella [17]
The work done to "HOLD" a load of bricks at any height is zero.
Work is done only when force acts through a DISTANCE.

The work done to LIFT 30 kg of anything to 20m higher than
it already is, is

(force) · (vertical distance)

= (mass) · (gravity) · (vertical distance)

= (30 kg) · (9.8 m/s²) · (20 m)

= 5,880 joules
