Explanation:
In series combination
R = R1 + R2 + R3 + ...+ Rn
In parallel combination
1/R = 1/R1 + 1/R2 + 1/R3 + ...+ 1/Rn
Answer:
The mass of the bullet is 15 g.
(b) is correct option.
Explanation:
Given that,
Momentum = 2.8 kg m/s
Speed = 187 m/s
We need to calculate the mass of the bullet
Using formula of momentum
Where, P = momentum
v = speed
Put the value into the formula
Hence, The mass of the bullet is 15 g.
Answer:
755 x 10⁻⁷ m
Explanation:
D = distance of screen
=2. m
d is width of slit = ?
wave length λ = 566 nm
Width of central maxima = 2 λD /d
= 3.00 x 10⁻² =2 λD /d
= 754.67 x 10⁻⁷ m .
= 755x 10⁻⁷ m
It is Continental polar ( only if this is for apex)
