Answer:

-2

Explanation:

The points are (0, 3) and (3, -3)

If you subtract 3-(-3) you get 6

If you subtract 0-3 you get -3

6/-3 is equal to -2

a wrench weighs 5.24 newtons on earth. when it is taken to the Moon, where g =1.16 m/s2 how much does it weigh?

Andrew [12]

“Weight of the wrench” on “the moon” is “6.07 kg”.

Explanation:

Weight of the wrench is 5.24 N

Weight of the wrench in kilograms = W × g

Taken “g” on the moon is $1.16 \mathrm{m} / \mathrm{s}^{2}$

$=5.24 \mathrm{N} \times 9.81 \mathrm{m} / \mathrm{s}^{2}=51.352 \mathrm{kg}$

Weight of the wrench in kilograms is 51.352 kg.

Formula to calculate weight of the object on the moon is

$\frac{\text {weight of the object on earth}}{9.81 \mathrm{m} / \mathrm{s}^{2}} \times 1.16 \mathrm{m} / \mathrm{s}^{2}$

Substitute the values given,

$=\frac{51.352 \mathrm{kg}}{9.81 \mathrm{m} / \mathrm{s}^{2}} \times 1.16 \mathrm{m} / \mathrm{s}^{2}$

$=5.234 \times 1.16$

= 6.07 kg

Therefore, weight of the wrench on the moon is 6.07 kg.

Two solid spheres are made from the same material, but one has twice the diameter of the other. Which sphere will have the great

aivan3 [116]

Answer:

It will be the same for both

Explanation:

from this question we have one similarity between these two spheres.

- they are both made from the same material,

The difference between both spheres is that:

- one of the spheres has its diameter to be twice as large as that of the other one.

We are to say the sphere with the greater bulk modulus.

If the material is the same thenthe Bulk modulus is also the same. It is not dependent on the material since it is a constant for that materia

Therefore the correct answer is:

It will be the same for both spheres.

It is desired to create a particle of mass 7920 MeV/c^2 in a head-on collision between a proton and an antiproton (each having a

Olegator [25]

Answer:

$v=0.9714c$

Explanation:

The kinetic energy possessed by particles will be

$K.E=\frac{1}{2}Mc^2$

where,

M is the mass of the particle (7920938.3 MeV/c²)

c is the speed of the light

Also,

energy of the proton particle = $\frac{m_pc^2}{\sqrt{1-\frac{v^2}{c^2}}}$

where,

v is the velocity

m_p is the mass of the proton (938.3 MeV/c²)

since the energy is equal

thus,

$\frac{m_pc^2}{\sqrt{1-\frac{v^2}{c^2}}}=\frac{1}{2}Mc^2$

$1-\frac{v^2}{c^2}=[\frac{2m_p}{M}]^2$

substituting the values in the above equation, we get

$1-\frac{v^2}{c^2}=[\frac{2\times 938.3 }{7920}]^2$

$v=0.9714c$

Hence, the speed necessary for the specified condition to occur is 0.9714 times the speed of the light

What region of the atom determines the volume of the atom

NeX [460]

Hello kiddio!

Most of the mass of atom is in a dense positively charged nucleus. Most of the volume of an atom is in an empty space in which negatively charged electrons move around the nucleus.

A standing wave of 603 Hz is produced on a string that is 1.33 m long and fixed on both ends. If the speed of the waves on this

kondaur [170]

Answer:

Explanation:

Given,

frequency of standing wave = 603 Hz

length of string,L = 1.33 m

speed of the wave, v = 402 m/s

number of antinodes = ?

Wavelength of the standing wave

$\lambda = \dfrac{v}{f}$

$\lambda = \dfrac{402}{603}$

$\lambda = 0.67\ m$

Number of anti nodes in the standing wave

$n=\dfrac{l}{\frac{\lambda}{2}}$

$n=\dfrac{2l}{\lambda}$

$n=\dfrac{2\times 1.33}{0.67}$

n =3.97= 4.

Number of antinodes is equal to 4.
