8 0

In the given question all the required details are given. Using these information's a person can easily find the momentum of the object. In the question it is already given that the mass of the object is 5 kg and the velocity at which it is traveling is 1.2 m/s.
We know the equation of finding momentum as
Momentum = mass * velocity
= 5 * 1.2
= 6
So the momentum of the object is 6 Newton.

Answer: P = 6 kg m/s

Explanation:

Momentum of an object is given by the product of mass and velocity. Any object in motion has momentum.

It is given by:

P = m v

where m is the mass and v is the velocity.

Here, m = 5 kg

v = 1.2 m/s

Thus, P = m v = 5 kg × 1.2 m/s² = 6 kg.m/s²

Choose the best explanation from among the following: A. It takes more energy to go from the Moon to the Earth because the Moon

nekit [7.7K]

Answer:

B. The escape speed of the Moon is less than that of the Earth; therefore, less energy is required to leave the Moon.

Explanation:

Since the speed required to escape from the gravitational attraction of the Moon is less than the speed required to escape from the gravitational attraction of the Earth, less energy is required to travel from the Moon to the Earth, than is required to travel from the Earth to the Moon. This is because the kinetic energy is directly proportional to the square of the velocity.

To sterilize a 53.0 g glass baby bottle, we must raise its temperature from 25.0°C to 92.0°C. How much heat transfer (in J) is r

Stella [2.4K]

The heat energy required is 2983 J

Explanation:

When an amount of energy Q is supplied to a certain sample of substance of mass m, the temperature of the substance increases by an amount of $\Delta T$ according to the equation :

$Q=mC_s \Delta T$

where

Q is the heat supplied

m is the mass of the object

$C_s$ is the specific heat capacity of the substance

$\Delta T$ is the change in temperature

For the glass bottle in this problem:

$m=53.0 g$

$\Delta T = 92.0 - 25.0 =67.0^{\circ}C$ is the change in temperature

$C_s = 0.84 J/g^{\circ}C$ is the specific heat of glass

Substituting into the equation, we find

$Q=(53.0)(0.84)(67)=2983 J$

A long, solid rod 5.3 cm in radius carries a uniform volume charge density. Part A If the electric field strength at the surface

Blizzard [7]

Answer:

$\rho = 7.35\times \muC/m^3$

Explanation:

given,

Radius of the solid rod, R = 5.3 cm

Electric field strength,E = 22 kN/C

Let the volume charge density be ρ

From Gauss law

$E = \dfrac{Rl}{2\epsilon_0}$

ε₀ is the permitivity of free space

R is the radius of the rod

and also,

$\rho=\dfrac{2E\epsilon_0}{R}$

ρ is the volume charge density

$\rho=\dfrac{2\times 22\times 10^{3}\times 8.854\times 10^{-12}}{0.053}$

$\rho = 7.35\times 10^{-6}\ C/m^3$

$\rho = 7.35\times \muC/m^3$

Hence, the volume charge density is equal to $\rho = 7.35\times \muC/m^3$

Which best explains why elements with a completely full outer shell of electrons do not usually bond with other elements to form

Alla [95]

The best answer is C.

The stability of atoms depends on whether or not their outermost shell is filled with electrons. If the outer shell is filled with electrons, the atom is stable and therefore they do not need to react with other elements to become stable.

On the other hand, atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability. To achieve stability, atoms will form two types of chemical bonds called ionic bonds and covalent bonds.
