Force on the particle is defined as the application of the force field of one particle on another particle. the electrical force between q₁ and q₃ will be –1. 1 × 10¹¹ N.

Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.

The electric force in the second case will be the same as in the first case. Therefore the force on the particle will be the same.

[tex]\rm F= K\frac{q_2q_3}{r^2}[/tex]

[tex]\rm F= 9\times 10^9 \times \frac{1.6 \times 10^{-13}\times 1.6\times10^{-13}}{(0.5)^2}[/tex]

[tex]\rm F= - 1. 1 \times 10^{11 }N[/tex]

Answer:

from top (youngest) to bottom (oldest) -

Conglomerate

Brecca

Shale

Dolostone

Explanation:

got it wrong from the person above and then it said this the right answer lol.

The oldest rock layer among the given options is shale then it is dolostone and then conglomerate and the youngest rock layer is Breccia.

Sedimentary rocks are formed from the sediments by river and ocean. These are developed over time by the action of wind and water. Sedimentary rocks are deposition or accumulation or minerals on the earth surface.

There are different types of rock layers based on the minerals present, age and formation.Shale rock is a clastic sedimentary rock formed flakes of clay minerals.

Conglomerate rocks is another clastic rock containing round clasts of more than two millimeters in diameter. Dolostone or dolomite is limestone and breccia is a mineral cement with fine sharp angled fragments.

The oldest among this is shale and the order for others from oldest to youngest is dolostone, conglomerate and breccia.

#SPJ2

Answer:

The answer is below

Explanation:

The question is not complete since the distance is not given. But let us assume the object moves a distance of 100 m.

From newton's law for a moving body, we get the equation:

v² = u² + 2as

Where v is the final velocity of the object, u is the initial velocity of the object, s is the distance moved by the object and a is the acceleration of the object.

Given that the object is initially at rest, hence u = 0, final speed (v) = 49 m/s, distance (s) = ?

v² = u² + 2as

Substituting:

49² = 0² + 2as

2401 = 2as

a = 2401 / 2s

Substituting s = 100 m

a = 2401 / (2*100)

a = 12 m/s²

Can you tell what the object's weight will be on another planet, such as Mars?

Answer: 34 kilograms (approximate)

==================================

Work Shown:

F = m*g

330 newtons = (m kg)*(9.8 m/s^2)

330 = m*9.8

330/9.8 = m

m = 33.673469387755

m = 34 kilograms

I'm rounding to 2 significant figures because 330 has 2 sig figs and 9.8 has 2 sig figs. When dividing we pick the smaller of the sig fig count to determine how many sig figs to round to.

We know that,

So, by using the third equation of motion, we will find out the final velocity of the ball.

[tex]\rule{200}{3}[/tex]

Therefore,

[tex] \sf \dashrightarrow {2as\ =\ v^2\ -\ u^2} \\ \\ \\ \sf \dashrightarrow {2 \times 10\ m/s^2 \times 30\ m\ =\ v^2\ -\ (0\ m/s)^2} \\ \\ \\ \sf \dashrightarrow {v^2\ =\ 600\ m^2/s^2} \\ \\ \\ \sf \dashrightarrow {v\ =\ \sqrt{600\ m^2s^{-2}}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{Final\ velocity\ (v)\ =\ 24.49\ m/s \approx 24.5\ m/s}}}}_{\sf \blue{\tiny{Required\ velocity\ of\ ball}}}} [/tex]

∴ Hence, the required final velocity of the ball with which it strikes the ground is 24.5 m/s. Since, we know that the initial velocity of the ball is 0 m/s and the acceleration of the ball is 10 m/s². So, by using the first equation of motion, we will find out the time of the ball after which it stikes the ground.

[tex]\rule{200}{3}[/tex]

Therefore,

[tex] \sf \dashrightarrow {v\ =\ u\ +\ at} \\ \\ \\ \sf \dashrightarrow {t\ =\ \dfrac{v\ -\ u}{a}} \\ \\ \\ \sf \dashrightarrow {t\ =\ \dfrac{24.5\ m/s}{10\ m/s^2}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{Time\ (t)\ =\ 2.45\ s}}}}_{\sf \blue{\tiny{Required\ time}}}} [/tex]

∴ Hence, the required time of the ball after which it strikes the ground is 2.45 seconds.

Answer:

181276.802 m

Explanation:

The computation of the horizontal range of the shell is shown below:

As we know that

range = u × usin2θ ÷ g

where,

u = 1600 m/s

θ = 68

g=9.81

Put these values to the above formula

So, the value of the horizontal range of the shell is

R = 181276.802 m

=  181276.802 m

We simply applied the above formula and the same is to be considered

Answer:

Given,

A 5 kg mass is at the origin. A 7 kg mass is located at x = 0.6 m and a 4 kg mass is at x = 0.9 m.

To find,

the net gravitational force on the 5 kg mass.

we know, from Newton's gravitational law, two massive bodies attract each other by a force , F = Gm₁m₂/r²

so, 7 kg mass attracts 5kg mass by the force, F₁ = G(7kg)(5kg)/(0.6)²

= 35G/0.36 = 97.22G

similarly, 4kg mass attracts 5kg mass by the force, F₂ = G(4kg)(5kg)/(0.9)²

= 20G/0.81 = 24.69G

net gravitational force = F₁ + F₂

= 97.22G + 24.69G

= 121.91G

we know, G = 6.67 × 10¯¹¹ Nm²/Kg²

F = 121.91 × 6.67 × 10¯¹¹

= 813.1397 × 10¯¹¹ N

= 8.131397 × 10^-9 N ≈ 8.13 × 10^-9 N

Therefore net gravitational force acting on mass 5kg is 8.13 × 10^-9 N

I believe that the correct answer is reactivity.

Ionic Compound

Explanation:

To identify the type of chemical bond in a molecule, look at the atoms that make up the compound. If there are two nonmetals, it is a covalent bond. If the two atoms are metals, it is a metallic bond. If one atom is a metal and the other is a nonmetal, it is an ionic bond. Ionic compounds are also known as salts. You can identify KBr as an ionic compound because potassium is a metal and a salt.

Hope this helps

The total surface area of the room is expressed as;

TSA = 2(LW+LH+WH)

L is the length

W is the width.

H is the height

Given

L = 4m

W = 3m

H = 2.5m

.TSA = 2{4(3)+3(2.5)+4(2.5)}

TSA = 2(12+7.5+10)

TSA = 2(29.5

TSA = 59m²

TSA (without the floor) = 2(3(2.5)+4(2.5))

TSA = 2(7.5+10)

TSA = 2(17.5)

TSA = 35m²

If a certain part covers 25 square meters per gallon, the amount of gallon needed will be 35m²/25m²

= 1.4gallons

We can confirm that the primary reason that killer whales cause deforestation of the seabed is due to a domino effect caused by one of their food sources.

Killer whales are carnivorous organisms. Among their prey are sea otters. This new source of food for killer whales began to cause a domino effect in that the decline in sea otter population caused the primary meal of the otters, that being sea urchins, to increase greatly in population. Given that the sea urchins feed on kelp, this contributes to the deforestation of the sea bed and the lack of kelp.

Therefore, we can confirm that killer whales cause deforestation of the seabed in an indirect manner by contributing to the increase in sea urchin populations that leads to deforestation of the seabed.
