Answer:The sun is not a particularly large star. It appears brighter because it is only 93 to 95 million miles away or about 8 light minutes. Whereas the next closest star is 4.5 light years away.

Explanation: does this need an explanation? no, exactly.

Displacement means when you move something from its original position. Let's say you want to sit on a chair. You move the chair from where it was originally placed. That's displacement.

Explanation:

The relationship between the length of the circle and its radius allows to find the result for the revolutions turned when the distance decreases  8.60m is:

           Angle = 17.8 rev

The length of a circle is given by the expression.

         L = 2π r

Where L is the length of the circle and r is the radius of the circle.

They indicate the radius of the drum is r = 7.71 cm = 7.71 10⁻² m, let's find the length of the circle.

         Lo = 2 π 7.71 10⁻²

         Lo = 0.4844 m

Let's find the angle that the drum has rotated, using a direct proportional rule. If rotate an angle of 2π radians when you descend 0.4844 m, what angle you rotate when you descend 8.60 m.

          #_ angles =  [tex]8.6 m \ \frac{2\pi \ rev} { 0.4844 m}[/tex]  

          #_angle = 111.55 radians

Let's reduce to revolutions.

         # _angles = 111.55 radians ( [tex]\frac{1 rev }{2\pi rad}[/tex] )

         #_angulo = 17.8 rev

In conclusion, using the relationship between the length of the circle and its radius, we can find the result for the revolutions turned when the distance decreases is:

           Angle = 17.8 rev

Answer:

Explanation:

If we make a rather silly assumption that the runner does not leap upward somewhat as he leaves the edge of the first building, his initial vertical velocity is zero.

The time needed to drop 5 meters from vertical rest is

t = √(2s/g) = √(2(5)/9.8) = 1.01 s

so he needs a horizontal speed of at least

v = d/t = 8 / 1.01 = 7.91959...

v = 7.9 m/s. Better make it 8 m/s to be sure he clears the edge and lands on the roof.

The distance above the ground the rock should be raised in order to hits the ground double of initial time is 4h.

The given parameters;

The time of motion of the rock from the given height is calculated as;

[tex]h = ut + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt_0^2\\\\h = \frac{1}{2} gt_0^2\\\\t_0^2 = \frac{2h}{g} \\\\t_0 = \sqrt{\frac{2h}{g} }[/tex]

When the time of motion is doubled to 2t₀, the height above the ground should be;

[tex]2(t_0) = 2(\sqrt{\frac{2h}{g} } )\\\\2(t_0) = \sqrt{\frac{4\times 2h}{g} }[/tex]

Thus, the distance above the ground the rock should be raised in order to hits the ground double of initial time is 4h.

Explanation:

The two statements identify evidence that energy was conserved are, as the car rolls down the ramp, it speeds up because gravitational

potential energy is transformed into kinetic energy and as the car rolls across the floor, it stops because its kinetic energy is transformed into thermal energy due to friction, therefore the correct answer is option C.

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.

As given in the problem statement a  toy car is released from rest at the top of a ramp. The car speeds up as it moves down the ramp. When it reaches the bottom of the ramp, the toy car rolls across the floor and

eventually stops.

Thus, it speeds up because gravitational potential energy is transformed into kinetic energy and as the car rolls across the floor, it stops because its kinetic energy is transformed into thermal energy due to friction, therefore the correct answer is option C.

The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).

The equilibrium condition allows finding the result for the tensions of the cables that support the block are:

       T₁ = 245.1 N and T₂ = 263.1 N

Newton's second law establishes a relationship between the net force, the mass and the acceleration of the bodies, in the special case that the acceleration is zero is called the equilibrium condition.

             ∑ F = 0

Where F is the force.

A free body diagram is a diagram of the forces without the details of the bodies, in the attachment we can see a free body diagram of the system.

Let's write the equilibrium condition for each axis.

x-axis

             T₂ₓ - T₁ₓ = 0

             T₂ₓ = T₁ₓ

y-axis  

         [tex]T_{1y} + T_{2y} - W =0[/tex]  

We use trigonometry to find the components of stress.

         cos 17 = [tex]\frac{T_{1x}}{T_1}[/tex]  

         sin17 = [tex]\frac{T_{1y}}{T_1y}[/tex]

         T₁ₓ = T₁ cos 17

         [tex]T_1_y[/tex]  = T₁ sin 17

         cos 27 = [tex]\frac{T_2_x}{T_2}[/tex]  

         sin27 = [tex]\frac{T_2_y}{T_2}[/tex]

         T₂ₓ = T₂ cos 27

         [tex]T_{2y}[/tex] = T₂ sin 27

We substitute.

        T₂ cos 27 = T₁ cos 17

        T₂ sin27 + T₁ sin17 = W

We solve the system.

        [tex]T_1 \frac{cos 17 \ sin 27}{cos 27} + T_1 sin 17 = m g \\T_1 ( tan 27 cos 17 + sin 17) = 19.5 \ 9.8[/tex]

        T₁ (0.7796) = 191.1

        T₁ = 245.1 N

We look for the T₂ tension.

        T₂ =  [tex]T_1 \ \frac{cos 17 }{cos 27}[/tex]  

        T₂ = 245.1  [tex]\frac{cos 17}{ cos 27}[/tex]  

        T₂ = 263.1 N

In conclusion, using the equilibrium condition we can find the result for the tensions of the cables that the block supports are:

       T₁ = 245.1 N and T₁ = 263.1 N

Explanation:

The terminal velocity of the skydiver is when the weight of the skydiver equals its air resistance therefore, the terminal velocity of the skydiver would occur at the 4th second. Therefore, option (D) is correct.

Terminal velocity can be described as the maximum velocity acquire by an object as it falls through a fluid. It happens when the sum of the drag force and the buoyancy is equal to the downward gravity acting.

Since the net force on the object is equal to zero, the object has zero acceleration. The object would attain the terminal velocity and start to move with a steady velocity.

An object is moving with terminal velocity if its speed is constant because of the restraining force exerted by the air or fluid through which it is moving.

At the 4th second, the weight of the skydiver is 500 N and the air resistance is equal to 500N. Therefore, the air resistance will be equal to the skydiver's weight. At this point, the forces will be balanced and the terminal speed will be attained.
