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.
He must throw the device AWAY from the ship.
Since momentum is conserved, that move will give HIM an equal amount of momentum TOWARDS the ship.
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.
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.
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.
