If you were trying to describe the difference between power and work you could say...?
Paha777 [63]

Answer:

Look to the explanation

Explanation:

<u><em>Work done</em></u> is  is the energy transferred to or from an object by means

of a force acting on the object.

Work is positive if energy transferred to the object, and  work is

negative if energy transferred from the object.

<em>Work = Force in the direction motion of object × its displacement</em>

W=F*s

The SI unit of the work is joule (J)

<u><em>Power</em></u> is the rate of work

<em>Power = work done ÷ time taken</em>

Power = \frac{F*s}{t}

Displacement (s) ÷ time (t) = velocity (v)

<em>Power = Force × velocity</em>

P=F*v

The SI unit of the power is watt (w)

Both segments of the wire are made of the same metal. Current I1 flows into segment 1 from the left. How does current I1 in segm
Andrei [34K]

Answer:

current I1 = current I2

Explanation:

since the wire is made up of the same material, from Kirchoff's current law sum of currents entering a particular node or segment of wire is equals to the sum of currents leaving that particular node or segment of wire

Pressure is about 1000 hPa at sea level and about 500 hPa at an altitude of 5.5 km. Why doesn’t this vertical pressure gradient
saul85 [17]

Answer:

A. The upward pressure gradient force is balanced by gravity.

Explanation:

A. is correct because the pressure difference is actually generated by gravity. As in the following formula for the pressure at different points:

p = p_0 + \rho g h

where p, p_0 are the pressure at 2 points, ρ is the density of the fluid, g is the gravitational constant, and h is the height difference.

B is incorrect because friction in air is too small to make an effect.

C is incorrect because the Coriolis force is horizontal, not vertical.

D is incorrect because a difference of 500 hPa = 50000 Pa, this is half of the atmospheric pressure.

E is incorrect because temperature cannot generate force.

A pivot at the 35cm mark supports a meter stick. It is brought into a balance by a 0.85N weight suspended at the 5.5cm mark.comp
Arte-miy333 [17]

Answer:

2.52N

Explanation:

according to law of moments ,

F1L1=F2L2 ,where the forces are in equilibrium .

0.85(44.5)= 15F2

that is , taking their distances from 50cm point

37 .825=15F2

37.825÷15= F2

2.52N = F2
