Bone has a Young’s modulus of about
MArishka [77]

Answer:

Explanation:

Bone has a Young’s modulus of about

1.8 × 1010 Pa . Under compression, it can

withstand a stress of about 1.66 × 108 Pa before breaking.

Assume that a femur (thigh bone) is 0.56 m

long, and calculate the amount of compression

this bone can withstand before breakin :).

What could you do to change the volume of a gas?
denis23 [38]
There are a number of ways you can change the volume of a gas.

Temperature: if you heat the gas it rises causing a change volume because the electrons gain more thermal energy BUT if you cool the gas down it sinks decreasing the molecules (the opposite effect)

Pressure can also change a gases volume. high pressure forces the molecules together creating a solid (along with cold temperatures)

Hope this helps!

Help plz I don't understand ​

#78

Airplane start with initial speed

v_i = 0

now the takeoff velocity is given as

v_f = 300 km/h

v_f = 83.33 m/s

acceelration is given as

a = 1 m/s^2

now we have

v_f - v_i = at

from above equation we have

83.33 - 0 = 1(t)

t = 83.33 s

#79

Airplane start with initial speed

v_i = 0

now the takeoff velocity is given as

v_f = 300 km/h

v_f = 83.33 m/s

acceelration is given as

a = 2 m/s^2

now we have

v_f - v_i = at

from above equation we have

83.33 - 0 = 2(t)

t = 41.7 s

Which force makes an object free fall?
LenaWriter [7]
Gravity

Explanation: ree fall is a special type of motion in which the only force acting upon an object is gravity. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity.

From the edge of a cliff, a 0.46 kg projectile is launched with an initial kinetic energy of 1430 J. The projectile's maximum up
wel

Answer:

Explanation:

Given

mass of Projectile(m)=0.46 kg

Initial Kinetic Energy=1430 J

Maximum upward displacement from Launch point=150 m

K.E.=\frac{mv^2}{2}

1430\times 2=0.46\times v^2

v=78.85 m/s

and H_{max}=\frac{v^2\sin ^2\theta }{2g}

150=\frac{(78.85)^2\sin ^2\theta }{2\times 9.8}

\sin \theta =0.687

\theta =43.39^{\circ}

initial horizontal velocity(v_x)=v\cos \theta

v_x=78.84\times \cos (43.39)=57.29 m/s

Initial vertical velocity(v_y)=v\sin \theta

v_y=78.85\times \sin (43.39)

v_y=54.16 m/s

(c)vertical velocity at any instant=65 m/s

Since initial vertical velocity is 54.16 m/s

so 65 m/s will be acquired when projectile started falling below cliff

v^2-u^2=2 a s

65^2-54.16^2=2\times 9.8\times s

s=65.90 m
