Answer:
Explanation:
The formula for the single-slit diffraction is
where
y is the distance of the n-minimum from the centre of the diffraction pattern
D is the distance of the screen from the slit
d is the width of the slit
is the wavelength of the light
In this problem,
, with n=2 (this is the distance of the 2nd-order minimum from the central maximum)
Solving the formula for d, we find:
When pushing a toy truck up an inclined plane, the force that makes the truck goes up is the force that the child uses to push the truck. (The force that pushes
Therefore the correct option is C.
The shape of the continents had been observed, that they fit together like a puzzle; this is easy to see with Africa and South America. Volcanoes and earthquakes had been found to only erupt in certain places - at the plate boundaries. Also, similar fossils had been found where the continents may have been connected. When satellite was introduced, some plate boundaries could even be seen from outer space.
The acceleration of the proton that is projected in the positive x direction into a region of a uniform electric field is 5.76×〖10〗^13 m/s^2
The product of the field's strength and the charge's strength yields the magnitude of the electric force acting on a charge traveling in a magnetic field region.
The electric force magnitude acting on the charge is expressed in the equation below.
F=|→E|×|q|
F=|-6.00×〖10〗^5 N/C|×||+1.602×〖10〗^(-19) C|
F=9.612×〖10〗^(-14) N
Newton's second law of motion states that the magnitude of a force is equal to the product of a proton's mass and its acceleration. Where the magnitude of the acceleration of the proton is ;
a=F/m
Where F is the force and m is the mass;
Inserting the values into the equation,
a=(9.612×〖10〗^(-14) N)/(1.67×〖10〗^(-27) kg)
a=5.76×〖10〗^13 m/s^2
Therefore, the acceleration of proton is 5.76×〖10〗^13 m/s^2 #SPJ4
