Answer:
Y = 3.39 x 10⁶ m
Explanation:
We will use Young's Double Slit formula here:

where,
Y = Fringe spacing = ?
λ = wavelength =
= 8 x 10⁵ m
L = screend distance = 4030 nm = 4.03 x 10⁻⁶ m
d = slit separation = 950 nm = 9.5 x 10⁻⁷ m
Therefore,

<u>Y = 3.39 x 10⁶ m</u>
Answer:
Current in each branch will be 2.5 A
Explanation:
We have given that a circuit has three branch each has a resistance of 37.5 ohm
We have also given that a total current of 7.5 A is flows through the circuit
As we know that in parallel circuit total current is the sum of current flowing through each branch
As the resistances of each branch is same so current will also be same
As there is 3 branches in circuit so current in each branch will be 
2.5N
Explanation:
Given parameters:
Mass of object = 500g
Acceleration = 5m/s²
unknown:
Resultant force = ?
Solution:
According to Newton's second law "the net force on a body or the resultant force is the product of its mass and acceleration".
Resultant or net force = m x a
where m is the mass
a is the acceleration
Now we need to convert the mass to kg
1000g = 1kg
500g =
= 0.5kg
Therefore;
Input the parameters:
Force = 0.5 x 5 = 2.5N
