Answer: c
Explanation:
Sound waves cannot travel through a medium
Answer:
C₁ = 3 pF
C₂ = 6 pF
Explanation:
Let the capacitance be C₁ and C₂.
For parallel combination
C₁ +C₂ = 9
For series combination


C₁ X C₂ = 18
( 9-C₂ )X C₂ = 18
C₂²- 9C₂ +18 = 0
C₂ = 6 or 3.
C₁ = 3 or 6.
C₁ = 3 pF
C₂ = 6 pF
Answer:
2. A force of 50 N is applied to the object for a distance of 2.0 m. Assume that object(the mass of the object is 3kg)
was at rest at the beginning, what speed did it achieved because of the work done on it? (Hint:
Calculate the works performed by the force first.)
I figured that is 8.2m/S,I am just not sure can anyone help me i much appreciate it.
Answer:
<h2>109.52 Hz</h2>
Explanation:
The frequency of the wave when given it's velocity and wavelength only can be found by using the formula

where
c is the velocity of the wave in m/s
is the wavelength in meters
From the question we have
c = 230 m/s
= 2.1 m

We have the final answer as
<h3>109.52 Hz</h3>
Hope this helps you
<h2>
Answer:
</h2>
Momentum
<h2>
Explanation:
</h2>
The momentum of a particle is defined as the product of the particle mass and the particle velocity as follows:

On the other hand, the impulse of a constant force is defined as:

We also know that the net force acting on a particle equals the rate of change of the particle’s momentum, so:

If the force is constant, then
equals the total change in momentum over a period of time:
