Answer:
9 kg
Explanation:
Momentum is mass times velocity.
p = mv
36 kgm/s = m (4 m/s)
m = 9 kg
An object with a greater mass will have more inertia as it takes more force to change their motion.
So, 50kg. (answer)
Hydrogen is written as H2 and oxygen is written as O2
When they bond it is a covalent bond.
Hydrogen has 1 negative electron , which would attract one from oxygen, so its outer shell would have 2 electrons.
Oxygen outer shell holds 8 electrons.
The answer is
2 and 8
Answer:
3.8 x 10^10 m/s^2
Explanation:
Charge, q = 2 e = 2 x 1.6 x 10^-19 C = 3.2 x 10^-19 C
Electric field strength, E = 790 N/C
mass of helium nucleus, m = 6.645 x 10^-27 Kg
the force due to electric filed on a charge particle is given by
F = q x E
Where, q be the charge on the charged particle and E be the strength of electric field.
By substituting the values
F = 3.2 x 10^-19 x 790
F = 2528 x 10^-19 N
According to the Newton's second law
F = m x a
Where, me be the mass and a be the acceleration
By substituting the values

a = 3.8 x 10^10 m/s^2
