When skier is moving along the hill we can say that he had some speed by which he is moving down

so his kinetic energy is given as

KE = \frac{1}{2}mv^2

also the height of the person is also there from ground level

so his potential energy is given as

PE = mgh

so here the correct answer would be

<em>The skier has potential and kinetic energy. </em>

Above the ground, a 1 m long wire is suspended horizontally perpendicular to a line running from its center to a nearby observer
Anit [1.1K]

Answer:

a) 0.09N b) positive x direction

Explanation:

Force on a conductor carrying current in a magnetic field can be expressed as;

F = BILsin(theta) where

F is the force on the conductor (wire)

B is the uniform magnetic field I'm Tesla = 1.8Tesla

I is the current in the wire = 5×10^-2A

L is the length of the wire = 1m

theta is the angle that the conductor make with the magnetic field = 90° (since the wire in the horizontal direction is perpendicular to the field acting upwards)

Substituting this value in the formula to get F we have;

F = 1.8×5×10^-2×1 × sin90°

F = 0.09N

The force on the wire is 0.09N

b) The direction of the force is in the positive x direction since the wire acts horizontally to the magnetic field.

7 One lb of Refrigerant 134a contained within a piston–cylinder assembly undergoes a process from a state where the temperature
julsineya [31]

Answer:

\Delta S = S_2-S_1 = 0.08835 \frac {BTU} {Lb ^ {\circ} R}

Explanation:

A) In order to solve the table it is necessary to consult tables A11-E and A10E for refrigerant R134-a

In this way we obtain that:

S_1 = S_f = 0.0648 \frac {BTU} {Lb. ^ {\circ} R}

In this way,

S_2 = S_f + x_2 (S_g-S_f) = 0.0902 + 0.5 (0.2161-0.0902)

S_2 = 0.15315 \frac {BTU} {Lb ^ {\circ} R}

In this way the entropy change is,

\Delta S = S_2-S_1 = 0.08835 \frac {BTU} {Lb. ^ {\°} R}

B) Whenever entropy yields a positive result, the process can be carried out adiabatically.

A small planet having a radius of 1000 km exerts a gravitational force of 100 N on an object that is 500 km above its surface. I
Mars2501 [29]
<h2>Option C is the correct answer.</h2>

Explanation:

Gravitational force is given by

                  F=\frac{GMm}{r^2}

         G=6.674×10⁻¹¹ m³⋅kg⁻¹⋅s⁻²

         M = Mass of object 1

          m = mass of object 2

          r = Distance between objects.

Here only variable is r value.

In case 1

             100=\frac{GMm}{(1000+500)^2}\\\\GMm=100\times 1500^2

In case 2

            F=\frac{GMm}{(1000+500+500)^2}\\\\F=\frac{GMm}{2000^2}\\\\F=\frac{100\times 1500^2}{2000^2}\\\\F=56.25N

Option C is the correct answer.

A body moves in a straight line. At time, it's acceleration is given by a = 12t + 1. When t =0, the velocity of the body v is 2
madreJ [45]

Answer:

v = 6t² + t + 2, s = 2t³ + ½ t² + 2t

59 m/s, 64.5 m

Explanation:

a = 12t + 1

v = ∫ a dt

v = 6t² + t + C

At t = 0, v = 2.

2 = 6(0)² + (0) + C

2 = C

Therefore, v = 6t² + t + 2.

s = ∫ v dt

s = 2t³ + ½ t² + 2t + C

At t = 0, s = 0.

0 = 2(0)³ + ½ (0)² + 2(0) + C

0 = C

Therefore, s = 2t³ + ½ t² + 2t.

At t = 3:

v = 6(3)² + (3) + 2 = 59

s = 2(3)³ + ½ (3)² + 2(3) = 64.5
