The light bends around the edges of the slit B I think
0 Newtons, since it's at a constant speed. Hope this helps, and Brainliest answer would be appreciated!
Applying the concept of scalar product. We know that vectors must be multiplied in their respective corresponding component and then add the magnitude of said multiplications. That is, those corresponding to the component are multiplied with each other, then those corresponding to the component and so on. Finally said product is added.
The scalar product between the two vectors would be:
Therefore the scalar product between this two vectors is 5.74
Solution :
The electric field between two plates is given by
where
permitivity of free space
q = charge
A = surface area
It is given that :
the radius of the circular plates , r = 30 mm
the current, I = 0.43 mA
Therefore, Magnetic field can be found by
Answer:
The final velocity is 8 m/s and its direction is along the positive x-axis
Explanation:
Given :
Mass, m₁ = 2000 g = 2 kg
Mass, m₂ = 4000 g = 4 kg
Initial velocity of mass m₁, v₁ = 24i m/s
Initial velocity of mass m₂, v₂ = 0
According to the problem, after collision the two masses are stick together and moving with same velocity, that is, .
Applying conservation of momentum,
Momentum before collision = Momentum after collision
Substitute the suitable values in the above equation.
