Calculating the acceleration of two people pulling a box with same force and angle.

Dmitriy789 [7]

Here as we can see there we be net horizontal force acting on it

$F_x = F_1cos20 + F_2cos20$

also we know that

$F_1 = F_2 = 80 N$

now we will have

$F_x = 2(80cos20)$

$F_x = 150.35 N$

now for net force of box we know

$F_x - F_f = ma$

$150.35 - 100 = ma$

$20a = 50.35$

$a = 2.52 m/s^2$

so acceleration of the box will be 2.52 m/s/s

A 15.0 m \long copper wire, 2.20 mm in diameter including insulation, is tightly wrapped in a single layer with adjacent coils t

Hoochie [10]

a) 0.5 m

b) $4.77\cdot 10^{-3} T$

Explanation:

At the beginning, the length of the copper wire is:

L = 15.0 m

and the diameter (so, the thickness of each adjacent circle) is

$t=2.20 mm = 0.0022 m$

While the diameter of one circle of the solenoid is

$d=2.10 cm = 0.021 m$

So the perimeter of one circle is

$p=\pi d=\pi (0.021)=0.0659 m$

So the number of complete circles in the solenoid is

$n=\frac{L}{p}=\frac{15.0}{0.0659}=227.6$

The tickness of one circle is $t$ , so the total length of the solenoid will be:

$L'=nt=(227.6)(0.0022)=0.5 m$

The magnetic field at the center of a solenoid is given by

$B=\mu_0 n I$

where

$\mu_0$ is the vacuum permeability

n is the number of turns of the solenoid

I is the current in the solenoid

Here we have:

$\mu_0 =4\pi \cdot 10^{-7}H/m$ is the vacuum permeability

$n=227.6$ is the number of turns in the solenoid (calculated in part a)

I = 16.7 A is the current in the solenoid

Substituting, we find:

$B=(4\pi \cdot 10^{-7})(227.6)(16.7)=4.77\cdot 10^{-3} T$

Physics Conversion help!!

stiv31 [10]

[Assuming that you've written 3.40 kg in 'a', and not 3.90 kg]

(a) 3,400 g x 0.001 = 3.40 kg [converting grams to kilograms]

(b) 220 cm x 0.01 = 2.2 m [converting centimeters to meters]

(d) 6.53 m x 100 = 653 cm [converting meters to centimeters]
