A wire carries a steady current of 2.20 A. A straight section of the wire is 0.750 m long and lies along the y axis within a uni
Akimi4 [234]

Answer:

2.805 N

Explanation:

Given,

Current, I = 2.20 A

Length of the section,L = 0.750 m

Magnetic field, B = 1.70 T

θ = 90°

Magnetic Force,F = ?

We know,

F = IBL sin θ

F = 2.20 x 1.70 x 0.750 x sin 90°

F = 2.805 N

Hence, magnetic force is equal to 2.805 N.

Kinetic energy....
saveliy_v [14]

Answer:

The ocean liner

Explanation:

Given that,

The mass of the bullet, m = 0.0014 Kg

The velocity of the bullet, v = 396 m/s

The mass of the ocean liner, M = 7.1 x 10⁷ Kg

The velocity of the ocean liner, V = 13 m/s

The kinetic energy is given by the formula,

                                 K.E = 1/2 mv²

1) The kinetic energy of the bullet,  

                                  K.E = 1/2 x 0.0014 x 396²

                                         = 109.775 J

2) The kinetic energy of the ocean liner,

                                 K.E = 1/2 x 7.1 x 10⁷ x 13²

                                        = 6 x 10⁹ J

Hence, the ocean liner has more kinetic energy.

Explain why stones are strong in compression but weak in tension ​
mafiozo [28]

Answer:

Gigantic towers, monuments and tall structures are always supported by a very thick layer of concrete that’s blended into their foundation. The purpose of this is quite straightforward: nothing provides greater support to a super heavy (and stationary) structure than a layer of concrete.  There may be other things that, in theory, could provide a stronger foundation, but they wouldn’t be nearly as cost effective as concrete.

Which statement accurately describes malleability? HELP ASAP!!!
vovangra [49]

Answer:

[]

Explanation:

Malleability is when a certain substance can be easily pressed, bent, or pulled out of shape permanently. An example of a malleable substance is gold, as it can be permanently pressed into a sheet and unable to return to its original state.
