Answer:
Virtually all the mass of an atom resides in its nucleus, according to Chemistry
Explanation:
The force applied to small piston = 2.2 x 10³ N
<h3>Further explanation</h3>
Given
a radius of 5 cm and 15 cm
weight 20000 N
Required
Force applied
Solution
Pascal Law :
F₁/A₁=F₂/A₂
A₁ = π.5²
A₂ = π.15²
F₁/ π.5² cm² = 20000/π.15² cm²
F₁ = 2222.22 N⇒2.2 x 10³ N
Answer:
Explanation:
Given that the force of the particle is,
Now it can be further written as
Now the initial conditions are v=1 at t=0.
So,
Now the velocity will become.
And,
And, another initial condition is x=0 at t=0
Now,
Answer:
For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.
Explanation:

Answer:
2 Hz.
Explanation:
Frequency is simply defined as the number of appearances of a periodic event occurring per time. It is usually measured in cycles/second.
Now, in this question, we are told that there are 2 cycles for each second.
Thus, we can say that the frequency is 2 cycles/1 s = 2 Hz.
