Answer:
217.43298 m/s
Explanation:
= Mass of bullet = 19 g
= Mass of bob = 1.3 kg
L = Length of pendulum = 2.3 m
= Angle of deflection = 60°
u = Velocity of bullet
Combined velocity of bullet and bob is given by

As the momentum is conserved

The speed of the bullet is 217.43298 m/s
Answer:
d₂=232.8 m
Explanation:
We know that formula for resolution given as
θres = 1.22 λ/d
Where
λ=wavelength
d=diameter
Given that resolution should be same.So we can say that
1.22 λ₁/d₁= 1.22 λ₂/d₂
λ₁/d₁= λ₂/d₂

Given that
λ₂=582 nm
λ₁=2 cm
d₁=8000 km

d₂=232.8 m
Answer:
The series A test tube has some left amount of glucose left in it.
Explanation:
Let's assume that a fixed amount of glucose is synthesized, for the fixed quantity the bacteria produced in A and B be x and y respectively,
Therefore, the condition on x and y is, y > x as the no. of bacteria present in B is greater.
As a result B would require a greater amount of energy for its functioning, these energy would be derived from the already fixed amount of glucose present.
A test tube would also require the energy for its x number of bacteria, but it is less than that of B.
Therefore, there would be some unused glucose left in Test Tube Series A which has unused energy.
