Answer:

10

Explanation:

We can look at this problem as a triangle, r is the hypotenuse so if we take the square root of 6^2+8^2 we get 10

Question 10 of 10

Margaret [11]

Answer: D. $5.0(10)^{-38} J$

Explanation:

The energy $E$ of an electromagmetic wave is given by:

$E=\frac{hc}{\lambda}$

Where:

$h=6.626(10)^{-34}J.s$ is the Planck constant

$c=3(10)^{8} m/s$ is the speed of light in vacuum

Then $hc=1.99 (10)^{-25}Jm$

$\lambda=4.0(10)^{12} m$ is the wavelength

Solving:

$E=\frac{1.99 (10)^{-25}Jm}{4.0(10)^{12} m}$

$E=5.0(10)^{-38} J$

While skydiving, your parachute opens and you slow from 50.0 m/s to 8.0 m/s in 0.75 s . Determine the distance you fall while th

Anestetic [448]

Answer:

21.75 m

Explanation:

t = Time taken for the car to slow down = 0.75 s

u = Initial velocity = 50 m/s

v = Final velocity = 8 m/s

s = Displacement

a = Acceleration

Equation of motion

$v=u+at\\\Rightarrow a=\frac{v-u}{t}\\\Rightarrow a=\frac{8-50}{0.75}\\\Rightarrow a=-56\ m/s^2$

Acceleration is -56 m/s²

$v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2a}\\\Rightarrow s=\frac{8^2-50^2}{2\times -56}\\\Rightarrow s=21.75\ m$

The distance covered in the 0.75 seconds is 21.75 m
