a crowbar having the lenght of 1.75 is used to balance a load of 500N if the distance between the fulcrum and the load is 0.5m f

Lemur [1.5K]

The effort applied = 200 N

<h3>Further explanation</h3>

Equilibrium :

$\tt F_1.d_1=F_2.d_2$

Total length = 1.75

The distance between the fulcrum and the load is 0.5 m ⇒ d₁=0.5 m

The distance between the fulcrum and the force applied :

$\tt 1.75-0.5=1.25~m\rightarrow d_2=1.25~m$

A load of 500N ⇒ F₁=500 N

The force applied :

$\tt 500\times 0.5=F_2\times 1.25\\\\F_2=\dfrac{500\times 0.5}{1.25}=200~N$

A long solenoid that has 1,140 turns uniformly distributed over a length of 0.350 m produces a magnetic field of magnitude 1.00

Troyanec [42]

Answer:

$I = 2.4 *10^{-2} A = 2.4 mA$

Explanation:

The magnetic field B inside long solenoid with current I is given as

$B = \frac{N \mu_o I}{L}$

where

N is number of turn of solenoids = 1140 turns

$\mu_0 = 4*\pi *10^{-7} T.m$

I is current that passes through solenoid

L is length along which current pass = 0.350 m

plugging value to get required value of current

$1.00*10^{-4} = \frac{1140*4*\pi *10^{-7} I}{0.350}$

$I = 2.4 *10^{-2} A = 2.4 mA$

Why does the mass of a candle decrease after burning?

34kurt

Because when a candle burns the wax is burning off so as its heated more and more wax is lost and if more wax is lost... Obviously it means that the candles mass will be lower :)
