A wire is stretched right to its breaking point by a 5000 N force. A longer wire made of the same material has the same diameter

. Is the force that will stretch it right to its breaking point larger than, smaller than, or equal to 5000 N? Explain.

Answer:

Equal to 5000N

Explanation:

The stress on the material is defined by force per unit of cross-sectional area. So it depends on the force and the diameter of the wire, which is the same for both wires. The material that defines the breaking point, is also the same. Therefore, both wires have their breaking point the same at 5000N. The wire length plays no role in here.

hram777 [196]

Answer:

option D

Explanation:

Power = work divided by time

and Work is equal to force multiplied by displacement

therefore power =\frac{35 \times 20}{10}  = 70

A trick shot archer shoots an arrow with a velocity of 30.0 m/s at an angle of 20.0 degrees with respect to the horizontal. An a
svlad2 [7]

Answer:

u'=10.259\ m.s^{-1} is the initial velocity of tossing the apple.

the apple should be tossed after \Delta t=0.0173\ s

Explanation:

Given:

  • velocity of arrow in projectile, v=30\ m.s^{-1}
  • angle of projectile from the horizontal, \theta=20^{\circ}
  • distance of the point of tossing up of an apple, d=30\ m

<u>Now the horizontal component of velocity:</u>

v_x=v\ cos\ \theta

v_x=30\times cos\ 20^{\circ}

v_x=28.191\ m.s^{-1}

<u>The vertical component of the velocity:</u>

v_y=v.sin\ \theta

v_y=30\times sin\ 20^{\circ}

v_y=10.261\ m.s^{-1}

<u>Time taken by the projectile to travel the distance of 30 m:</u>

t=\frac{d}{v_x}

t=\frac{30}{28.191}

t=1.0642\ s

<u>Vertical position of the projectile at this time:</u>

h=v_y.t-\frac{1}{2}g.t^2

h=10.261\times 1.0642-\frac{1}{2} \times 9.8\times 1.0642^2

h=5.3701\ m

<u>Now this height should be the maximum height of the tossed apple where its velocity becomes zero.</u>

v'^2=u'^2-2g.h

0^2=u'^2-2\times 9.8\times 5.3701

u'=10.259\ m.s^{-1} is the initial velocity of tossing the apple.

<u>Time taken to reach this height:</u>

v'=u'-g.t'

0=10.259-9.8\times t'

t'=1.0469\ s

<u>We observe that </u>t>t'<u> hence the time after the launch of the projectile after which the apple should be tossed is:</u>

\Delta t=t-t'

\Delta t=1.0642-1.0469

\Delta t=0.0173\ s

A young diver is practicing his skills before an important team competition. Use the diagram below in order to analyze the energ
skad [1K]
  • Mass of the diver (m) = 90 Kg.
  • Height of the board from the ground (h) = 10 m.
  • Acceleration due to gravity (g) = 9.8 m/s^2.
  • Height of the diver from the ground when he reaches point C (x) = 5m
  • Initial velocity (u) = 0 m/s
  • We know, gravitational potential energy of a body = mass × acceleration due to gravity × height.
  • Therefore, the gravitational potential energy of the diver when he reaches point C (GPE) = mg(h - x)
  • or, GPE = [90 × 9.8 × (10-5)] J
  • or, GPE = [90 × 9.8 × 5] J
  • or, GPE = 4410 J
  • For a freely falling body,
  • v^2 - u^2 = 2gh
  • or, v^2 = 2gh
  • We know, kinetic energy of a body = 1/2 mv^2
  • Therefore, kinetic energy of the diver when he reaches point C (KE) = 1/2 m(2gx)
  • Here, 2gx = (2 × 9.8 × 5) = 98 (m/s)^2
  • We have already seen v^2 = 2gh
  • or, v = √2gh
  • So, the velocity of the diver = √2gx = √98 m/s = 9.9 m/s
