How many seconds will it take to travel 3,600 meters if your speed is 90 meters per second?

klio [65]

40

Because if you divide 3,600 by 90 it is equivalent to 40.

Hope this helps, have a blessed day :)

A 2.3 m -long wire carries a current of 8.6 A and is immersed within a uniform magnetic field B⃗ . When this wire lies along the

Volgvan

Answer:

Explanation:

Given that :

The current I = 8.6 A

The length vector L = 2.3 m i

The force vector is = -2.0 j N

When L = 2.3 m i ; the

Force vector F = (2.0 i - 4.8 k) N

Compute the components of the magnetic field as follows:

$F = I(L*B)$

Replacing 8.6 A for I ; -2.0 j N for F & 2.3 m i for L

$-2.0 j N = (8.6 A) (2.3 m i *(B_xi + B_yj+B_zk)$

$-2.0 j N = 19.78B_z \ and \ 0 = 19.78B_y$

$B_z = -0.1011 T \ and \ B_y = 0$

However in y direction ; we have :

$(2.0 i - 4.8 k) = 8,6 A (2.3 mi*(B_xi+B_yj+B_zk)$

$- 2.0 = 19.78 B_z \ and \ -4.8 = 19.78 B_x$

$B_z = -0.1011 T \ and \ B_x = -0.2427T$

Hence, the component of magnetic field is as follows:

$B_x = -.02427T \ ; B_y = 0 T \ ; B_z = - 0.1011 T)$

The gas in a balloon has T=280K and V=0.0279m^3. If the temperature increases to 320K at constant pressure, what is the new volu

photoshop1234 [79]

Answer:

$\boxed{ V_{2}= 0.03189 m^3}$

Explanation:

According to Charles Law

=> $\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$

Where $V_{1}$ = 0.0279 m³, $T_{1}$ = 280 K and $T_{2}$ = 320 K

=> $\frac{0.0279}{280} = \frac{V_{2}}{320}$

=> $V_{2}$ = 0.03189 m³
