Answer:
d = 185.26 meters
Explanation:
It is given that,
Launching angle of the projectile, 
Initial speed of the projectile, u = 48 m/s
Let at distance d the projectile hits the ground from the launch point. It is equal to range of the projectile. Its formula is given by :
Substituting all the values in above formula. So, we get :
d = 185.26 meters
So, the distance between the launch point and the point where it hits is 185.26 meters. Hence, this is the required solution.
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.
Answer:
Explanation:
tangential acceleration at = 3.1 m / s²
angular acceleration = tangential accn / radius
= 3.1 / r , r is radius of the cylinder .
IF N₁ be no of rotation in time t
θ = 1/2 α t² , α is angular acceleration , θ is angle in radian covered in time t
2π N₁ = 1/2 (3.1 / r ) x 2.9²
N₁ = 2.0757 / r
similarly we can calculate
2πN₂ = 1/2 (3.1 / r ) x 10²
N₂ = 24.68 / r
N₂ / N₁ = 11.89
The are elements on the periodic table
