Here when car in front of us applied brakes then it is slowing down due to frictional force on it
So here we can say that friction force on the car front of our car is given as
So the acceleration of car due to friction is given as
now it is given that
so here we have
so the car will accelerate due to brakes by a = - 8.52 m/s^2
Density =mass/Volume
0.8=mass/60
Mass=0.8*60
Mass=48g
Mr. Roentgen's x-rays allowed scientists to measure the size of the atom. The x-rays were small enough to discern the atomic clouds. This was done by scattering x-rays from atoms and measuring their size just as Rutherford had done earlier by hitting atoms with other nuclei starting with alpha particles.
The speed of the wave is mathematically given as
v=2266.66m/s
A long wave with a period of about 15 minutes will travel across the oceans at a speed of approximately v=2266.66m/s
<h3>
Speed of the wave</h3>
Question Parameters:
A long wave with a period of about 15 minutes
Generally the equation for the Wave velocity is mathematically given as
v=\lambda * frequency
Where
f=1/t
Therefore
v=\lambda * frequency
v=\lambda * 1/t
Therefore, with wavelenght of the ocean as 34km
v=34*1000*1/15
v=2266.66m/s
