Answer:
Momentum of bullet
momentum of baseball
Explanation:
As we know that momentum is defined as the product of mass and velocity
here we know that
mass of the bullet = 8 gram
velocity of bullet = 340 m/s
momentum of the bullet is given as
Now we have
mass of baseball = 0.2 kg
velocity of baseball = 40 m/s[/tex]
momentum of baseball is given as
Answer: Option (c) is correct answer.
Explanation:
The given reaction equation is as follows.
The number of atoms on reactant side are as follows.
The number of atoms on product side are as follows.
Therefore, in order to balance the equation we will balance the number of atoms in both reactant and product side.
Since number of Fe atoms in reactant side is 2, therefore, multiply by 2 in the product side.
Number of O atoms in reactant side is 3, therefore, multiply by 3 in the product side.
Now, the number of H atoms on product side is 6, therefore, multiply HCl by 6 in the reactant side.
The number of chlorine atoms on both reactant and product side equals 6.
Thus, the equation will become as follows.
Hence, the equation is balanced.
Solution :
From the given data,
For the spherical shell is
where x is the radius of gyration and the acceleration of a rolling body on an inclined plane = a
Therefore,
= 0.6 x 9.81 x sin ( 29.7)
Δt = 1.411 s
