A 40 N crate rests on a rough horizontal floor. A 12 N horizontal force is then applied to it. If the coecients of friction are
bixtya [17]

Answer:

Fr = 20 (N)

Explanation: See atached file ( free body diagram)

As for Newton´s low

∑ Fy  =  0

-mg + N = 0        ⇒  - 40 + N = 0       ⇒ N  = 40 [Newtons]

by definition :  Fr = μs * N        ⇒  Fr = 0,5 * 40      ⇒  Fr = 20 (N)

∑ Fx  =  0   body is at rest

Fe - Fr = 0

Fr > Fe

Fr > 12 (N)  the body is at rest

ichrome wire of cross-sectional radius 0.791 mm is to be used in winding a heating coil. If the coil must carry a current of 9.2
77julia77 [94]

Answer:

length is 23.228091 m

Explanation:

Given data

radius = 0.791 mm = 0.791 × 10^{-3} m

current =  9.25 A

voltage =  1.20 × 10² V

to find out

resistance and  length of wire

solution

we know the resistance formula that is

resistance = voltage / current

resistance = 1.20 × 10²  /9.25

resistance = 12.97

so resistance is 12.97 ohm

and length of nichrome wire formula is

length = resistance × area /  specific resistance of wire  

so specific resistance of wire  we know = 1.1 × 10^{-6}

and area = \pi × r² = \pi × (0.0791× 10^{-3})²

area = 1.97 × 10^{-6}

length =   12.97  × 1.97 × 10^{-6}  /  1.1 × 10^{-6}

so length is 23.228091 m
