Answer:

22.4\:\mathrm{kg\cdot m/s}

Explanation:

Momentum is given by p=mv.

Let p_1 be the initial momentum of the object:

p_1=m\cdot v=22.4

If we doubled the mass, the new mass would be 2\cdot m, and if we halved the velocity, the new velocity would be \frac{1}{2}\cdot v.

Therefore, the final momentum would be:

p_f=2\cdot m\cdot \frac{1}{2}\cdot v=m\cdot v=\fbox{$22.4\:\mathrm{kg\cdot m/s}$}..

Consider and mass of a material​
Leni [432]

Answer:Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). ... You probably have an intuitive feeling for density in the materials you use often. For example, sponges are low in density; they have a low mass per unit volume.

Use Eq. cosϕ=R/Z to show that the average power delivered by the source in an L−R−C series circuit is given by Pav = I^2rmsR .
Evgen [1.6K]

Answer:

Explanation:

In a L C R circuit, the average power is given by

P_{av}=V_{rms}I_{rms}Cos\phi

As given in the question

CosФ = R / Z

And we know that

V_{rms}=I_{rms}\times Z

So

P_{av}=I_{rms}\times Z\times I_{rms}\times \frac{R}{Z}

P_{av}=I_{rms}^{2}\times R
