Answer:

<h2>0.2 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{100}{500}  =  \frac{1}{5}  = 0.2 \\

We have the final answer as

<h3>0.2 m/s²</h3>

Hope this helps you

ivann1987 [24]

The two components of projectile motion include the following:

  • Horizontal motion
  • Vertical motion.

<h3>What is a Projectile?</h3>

This is defined as a missile propelled by the application of an external force and allowed to move freely under the influence of gravity and air resistance.

The equation for Horizontal motion Vx = V * cos(α)

Vertical velocity component: Vy = V * sin(α)

Consider Compton Scattering with visible light.A photon with wavelength 500nm scatters backward(theta=180degree) from a free ele
JulijaS [17]

Answer: 4.86(10)^{-12}m

Explanation:

The Compton Shift \Delta \lambda in wavelength when photons are scattered is given by the following equation:

\Delta \lambda=\lambda' - \lambda_{o}=\lambda_{c}(1-cos\theta) (1)  

Where:  

\lambda'=500 nm=500(10)^{-9} m is the wavelength of the scattered photon

\lambda_{o}  is the wavelength of the incident photon

\lambda_{c}=2.43(10)^{-12} m is a constant whose value is given by \frac{h}{m_{e}.c}, being h=4.136(10)^{-15}eV.s the Planck constant, m_{e} the mass of the electron and c=3(10)^{8}m/s the speed of light in vacuum.  

\theta=180\° the angle between incident phhoton and the scatered photon.  

\Delta \lambda=2.43(10)^{-12} m (1-cos(180\°)) (2)

\Delta \lambda=4.86(10)^{-12}m (3)  This is the shift in wavelength

A water tower 30 m tall is located at the top of a hill. From a distance of D = 160 m down the hill, it is observed that the ang
professor190 [17]
For this we need to use sinus law because there is no right angle in the observed triangle to solve it in some easier way.

\frac{a}{sin( \alpha )} = \frac{b}{sin( \beta )}

where a is height of the water tower, b is length from point of view till bottom of the tower, \alpha is the angle from point of view and \beta is angle opposite from b.

We use this law to calculate beta angle.

sin( \beta ) =  \frac{b}{a} *sin( \alpha )

sin( \beta ) = 0.742
\beta = 47,924

Now we observe different angle. Bottom of the hill-top of the tower-point of view. We calculate angle at point of view (notice how it is different than previous one).

180-90-47.924 = 42.076

At last, the hill inclination is:
42.076 - 8 = 34.076 = 34.1
