The momentum of an object is determined to be 7.2 × 10-3 kg⋅m/s. Express this quantity as provided or use any equivalent unit. (

slavikrds [6]

Answer:

Momentum, p = 7.2 g-m/s

Explanation:

It is given that,

The momentum of an object is $p=7.2\times 10^{-3}\ kg-m/s$

We need to express momentum in any equivalent units. There can be many solutions of this problem. Some of the units of mass are gram, milligram etc. units of length are meters, mm etc.

Since, 1 kg = 1000 gram

So, $p=7.2\times 10^{-3}\times 10^3\ g-m/s$

Therefore, the momentum of the object is 7.2 g-m/s. Hence, this is the required solution.

A water tank has a square base of area 8 square meters. Initially the tank contains 70 cubic meters. Water leaves the tank, star

OLEGan [10]

Answer:

Explanation:

Given

base of water tank $A=8\ m^2$

Initial volume of water $V=70\ m^3$

Water leaves the tank at the rate of

$\frac{\mathrm{d} V}{\mathrm{d} t}=-(2+4t^3)$

Integrating rate to get desired volume

at $t=0,V=70\ m^3$

at $t=3\ hr,V=V$

therefore

$\int_{70}^{V}dV=\int_{0}^{3}-\left ( 2+4t\right )dt$

$V-70=2t+2t^2|_0^3$

$V-70=-24$

$V=46\ m^3$

and $volume=Area\times h$

$h=\frac{V}{A}$

$h=\frac{46}{8}$

$h=5.75\ m$

Thus height of water remaining is $5.75\ m$

Se tiene un objeto a una altura de 8 m generando 450 J de energía potencial cuál es la masa de dicho objeto

fgiga [73]

Answer:

5.73kg

Explanation:

Given data

Height = 8m

Potential Energy = 450J

Required

The mass of the object

From the following expression

PE=mgh

we can substitute g= 9.81m/s^2 and the other parameters to get mass m

450= m*9.81*8

450= m* 78.48

m= 450/78.48

m= 5.73kg

Hence the mass is 5.73kg
