A grocery cart with a mass of 15 kg is pushed at constant speed along an aisle by a force fp = 12 n which acts at an angle of 17
Korolek [52]

<span>Given:

Mass of cart: 15kg</span>

Aisle length = 14m

Angle = 17° below the horizontal

Force fp = 12 N

 

So, the solution would be like this for this specific problem:

 

<span><span>1)    </span>W(by applied force) = F(applied) x s x cosθ <span>
=>W(a) = 12 x 14 x cos17* = 160.66 J </span></span>
<span><span>
2)    </span>By F(net) = F(applied) - F(friction) <span>
=>As v = constant => a = 0 => F(net) = 0 
=>F(applied) = F(friction) 
<span>=>W(friction) = -F(friction) x s
=>W(friction) = -F(applied) x s 
=>W(f) = -12 x 14 x cos17* = -160.56 J </span></span></span>
<span><span>
3)    </span>0, as the displacement is perpendicular to Force </span>
<span><span>
4)    </span>0, as the displacement is perpendicular to Force</span>  
<span>
To add, the force that is applied<span> to an object by a person or another object is called the applied force.</span></span>

The metric system is now known as the international system of units.<br> a. T<br> b. F
inn [45]
<span>The metric system is the oldest name for the international system of units. The answer is <u>a. True. </u>SI unit or the international systems of units are based on seven basic units; the meter, kilogram, second, ampere, Kelvin, candela and mole. All of these basic units are divided into multiples by a power of ten. For example in meters, 1 meter is equal to: 1000 millimeter, 100 centimeter, 10 decimeter, 0.1 decameter, 0.01 hectometer, 0.001 kilometer and so on and so forth.</span>

A 30 cm-long wire carrying a current of 0.5 A is immersed in a uniform magnetic field of 4 T. If the magnetic field is oriented
Lera25 [3.4K]

Answer:

Magnetic force, F = 0.6 N

Explanation:

It is given that,

Length of the wire, L = 30 cm = 0.3 m

Current carrying in the wire, I = 0.5 A

Uniform magnetic field, B = 4 T

To find,

The magnetic force

Solve,

A force is exerted by the wire in the magnetic field that is given by :

F=ILB\ sin\theta

Here, \theta=90

F=ILB

F=0.5\ A\times 0.3\ m\times 4\ T

F = 0.6 N

Therefore, the magnetic force exerted by the wire in the magnetic field is 0.6 N
