A light, flexible cable is wrapped around a solid cylinder with mass 3.3 kg and a radius of 0.8 meters. The cylinder rotates on

kari74 [83]

Answer:

$9.16rad/s^2$

Explanation:

We are given that

Mass, $m_1=3.3 kg$

Radius,r=0.8 m

$m_2=4.9 kg$

Height,h=2.9 m

We have to find the angular acceleration of the cylinder.

According to question

$4.9g-T=4.9a$

$Tr=I\alpha$

Where

$\alpha=\frac{a}{r}$

$Tr=\frac{1}{2}m_1ra$

$T=\frac{1}{2}m_1a=\frac{1}{2}(3.3)a$

Substitute the value

$4.9g-\frac{1}{2}(3.3a)=4.9a$

$4.9\times 9.8=4.9a+\frac{3.3a}{2}$

Where $g=9.8 m/s^2$

$48.02=a(4.9+1.65)=6.55a$

$a=\frac{48.02}{6.55}=7.33m/s^2$

Angular acceleration, $\alpha=\frac{a}{r}=\frac{7.33}{0.8}=9.16rad/s^2$

One long wire lies along an x axis and carries a current of 43 A in the positive x direction. A second long wire is perpendicula

qwelly [4]

Answer:

Bnet=1.006*10^-6T

Explanation:

One long wire lies along an x axis and carries a current of 43 A in the positive x direction. A second long wire is perpendicular to the xy plane, passes through the point (0, 5.9 m, 0), and carries a current of 41 A in the positive z direction. What is the magnitude of the resulting magnetic field at the point (0, 1.7 m, 0)?

the magnetic field Bnet= $\sqrt{b1^2+b2^2}$

the magnetic field due this long wire is given by

B1=∨I1/ $(2\pi *R1)$ ..............................1

B2=∨I2/ $(2\pi *R2)$ ............................2

Bnet= $\sqrt{(vI1/2*pi*R1)^2+(vI2/2*pi*R2)^2}$ .......................3

Bnet=v/2*pi $\sqrt{(I1/R1)^2+(i2/R2)^2}$

Bnet=4*pi*10^-7/(2 $\pi$ ) $\sqrt{(43/1.7)^2+(41/29.5)^2}$

Bnet=0.0000002*(641.72)^.5

Bnet=1.006*10^-6T

Why is venus the hottest planet in the solar system

mr Goodwill [35]

Venus is the hottest world in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth.
