Natalia lifts a bag of groceries 0.50 m by exerting a force of 36 N. How much work did she do on the bag?
Kruka [31]
<h3><u>Answer;</u></h3>

18 Joules

<h3><u>Explanation;</u></h3>
  • <em><u>Work is the measures the transfer of energy when an object moves over a given distance.</u></em>
  • Work is therefore given by; Force × distance

Force =36 Newtons

Distance = 0.5 meters

  • Hence; <em>work = 36 N × 0.5 N</em>

<em>                                = 18 Joules </em>

a radio controlled car rolls 10 m south then reverses direction and rolls 8 m north the car traveled a distance of 18 m and has
EastWind [94]

The displacement is 2 m south

Explanation:

Distance and displacement are two different quantities:

  • Distance is the total length of the path covered by an object during its motion, regardless of the direction. It is a scalar quantity
  • Displacement is a vector connecting the initial position to the final position of motion of an object. The magnitude of the displacement is the distance in a straight line between the two points

For the car in this problem, the motion is:

10 m south

8 m north

Taking north as positive direction, we can describe the two parts of the motion as

d_1 = -10 m

d_2 = +8 m

Therefore,  the final position of the car with respect to the original position is

x_f = -10 + 8 = -2 m

which means 2 m south: so, the displacement of the car is 2 m south.

A huge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. The uppe
TiliK225 [7]

Answer:

E = 6.77 *10^{3} N/C

Explanation:

THE GIVEN sheet can be taken as two horizontal force  with surface charge density is

at one surface is ∈_1 = 95*10^ {-9} C/mm2

at oher surface is ∈_2= -25*10^{-9} C/mm2

the magnitude of electric field due to surface charge is given as\frac{∈}{2∈_O}

So, electric field at P (2 CM below from surface is) = E_1 +E_2

E = \frac{∈_1}{2∈_O} +\frac{∈_2}{2∈_O}

E = \frac{95*10^{-9} +25*10^{-9}}{2*8.85*10^{-12}}

E = 6.77 *10^{3} N/C

8 A car accelerates at a rate of 10m/s
zheka24 [161]

Answer:

From the First Law of Motion

Vf = Vi + at

"It reaches a speed of 52m/s" meaning the Final speed Vf=52

a(acceleration)=10m/s²

t=4s

Applying the formula

52=Vi + 10(4)

Vi = 52-40

Vi = 12m/s
