The answer and solution to how to calculate the minimum steam force.

Answer:

[tex]resolving \: \\ (\downarrow_{ + }) \: s = ut + \frac{1}{2} g {t}^{2} \\ u = 0 ,\: g = 9.81m. {s}^{ - 2} , \: t = 5s \\ s =h= \frac{1}{2} g {t}^{2}, = \frac{1}{2} (9.81){5}^{2}\\=4.9\times25 \\ h=122.6m[/tex]

Answer:

Final velocity = 7.4m/s

Explanation:

Use the equation:

acceleration = (final velocity - initial velocity)/time

Rearrange to get:

final velocity = (acceleration * time) + initial velocity

Now just substitute with the values you already have:

Final velocity = (-9.8m/s^2 * 0.7s) + 0.5m/s

Final velocity = 7.36m/s

We are using 2 sig-figs, so:

Final Velocity = 7.4m/s

The characteristics of the ionic bonds allows to find the results for the question about which compound are ionic is:

    d) Compounds D and A.

Chemical compounds are formed by atoms linked by electrostatic forces, where one of the elements gave up some electrons and the other element acquired these electrons, the two atoms being in an ionic state, consequently the bond is strong and has several characteristics:

In these characteristics, let's analyze the compounds in the table.

Let's review the different alternatives:

a) False. Compound A and B has a low melting point.

b) False. The B and C compounds have low melting points.

c) False. Compound C has a low melting point.

d) True. The two compounds meet all the characteristics of ionic compounds.

In conclusion with the characteristics of the ionic bonds we can find the results for the question about which compound are ionic is:

       d) Compounds D and A are ionics.

Explanation:

Balanced Forces

In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force. You observed that the object did not move. When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.

Answer: Convection currents in the molten mantle cause the plates to slowly move about the Earth a few centimeters each year. Many ocean floor features are a result of the interactions that occur at the edges of these plates.

Explanation:

The convection currents can be seen in a crowd, in the ocean, and can also be felt underground.

A convection current simply means the process that has to do with the movement of energy from one particular place to another.

A convention current is also known as convection heat transfer. Convention currents are due to differential heating. This brings about the circulation patterns that are referred to as convection currents that can be found in the atmosphere, water, and the mantle.

Answer:

It should be less energy

Explanation:

The further away from the nucleus, the more it holds, correct? So those closer to the nucleus hold less electrons. So therefore, the ones that are closer must have more energy than the outer electrons.

Answer:

The gas, which is usually a hydrocarbon fuel, provides the energy. So when the fuel burns with oxygen in the air, it creates heat energy.

Explanation:

Therefore, chemical energy in carbon is released during the combustion process. Carbon dioxide is created, because the carbon-oxygen chemical bonds in the carbon dioxide form which releases heat.

Answer:

Displacement=10 meters

Explanation:

The displacement is the direct path from the first contact with the ball and the last spot it was seen in. The ball was kicked north 8 meters, meaning it was kicked vertically upward, and then it was kicked east 6 meters, or to the right. If we were to draw the displacement we would see that this is a right triangle. That means we can use the Pythagorean Theorem:

[tex]a^2+b^2=c^2\\8^2+6^2=c^2\\64+36=c^2\\c^2=100\\\sqrt{c} =\sqrt{100} \\c=10[/tex]

Boom.

The displacement is 10 m toward the northeast. The first option is correct.

The displacement is a vector quantity having both magnitude and direction. It is equal to the path length between the initial and final positions.

Given:

North displacement, y=8 m

East displacement, x= 6 m

The net displacement is calculated using Pythagoras' theorem as the displacements are perpendicular to each other.

The displacement is given by:

d=√(x²+y²)

d=√(8²+6²)

d=10 m

So, the displacement is 10 m.

Therefore, the displacement is 10 m toward the northeast. The first option is correct.

Hi there!

Because of Newton's Third Law, the force exerted by the sprinter on the track is equal and opposite to the force exerted by the track on the sprinter.

We can begin by calculating the sprinter's acceleration. Use the equation:

vf² = vi² + 2ad

Rearrange for acceleration:

(vf² - vi²)/2d = a

Plug in values:

(8² - 2²)/2(2.5) = 60/5 = 12 m/s²

Calculate the force:

∑F = ma

∑F = 60 × 12 = 720 N. This is the amount of force exerted by the track on the sprinter in causing him to accelerate forward.

Thus, the backward force exerted by the sprinter on the track is the opposite, or -720 N.
