Answer:10.4 times of initial velocity
Explanation:
Given
Diameter reduced by 69 %
it approaches with velocity 
suppose its velocity is v during blocked passage
suppose d is the initial diameter and
diameter is



As flow is constant



Answer:
The correct answer option is C
Explanation:
In a balanced chemical reaction mass of the reactant are always equal to mass of the products. Also known as Law of Conservation of Mass which states that " mass can nor be created nor be destroyed in a chemical reaction."
So, the mass of the reactant will be equal to the mass of products.That is 120 grams.
Hence, the correct answer option(C).
Answer:
The bird's speed immediately after swallowing is 4.98 m/s.
Explanation:
Given that,
Mass of bird = 290 g
Speed = 6.2 m/s
Mass of sees = 9.0 g
Speed = 34 m/s
We need to calculate the bird's speed immediately after swallowing
Using conservation of momentum

Put the value into the formula



Hence, The bird's speed immediately after swallowing is 4.98 m/s.
Answer:
8.37×10⁻³ C.
Explanation:
The formula of electric field is given as
E = kq/r².......................... Equation 1
Where E = electric field, q = amount of charge, k = coulomb constant, r = radius of the sphere
make q the subject of the equation
q = Er²/k .................... Equation 2
Given: E = 3.01×10⁶ N/C, r = 5.0 m, k = 8.99×10⁹ Nm²/C².
Substitute into equation 2
q = (3.01×10⁶)(5²)/(8.99×10⁹)
q = (75.25/8.99)×10⁻³
q = 8.37×10⁻³ C.
Hence the maximum amount of charge = 8.37×10⁻³ C.
