Mike has a mass of 97 kg. He jumps out of a perfectly good airplane that is 2000 m above the ground. After he falls 1000 m, when

Ne4ueva [31]

Answer:

a) fr = 224.3 N , b) fr = 224.3 N , c) v = 198.0 m/s

Explanation:

a) For this exercise let's start by calculating the acceleration in the fall

v² = v₀² - 2 a (y-y₀)

When it jumps the initial vertical speed is zero

a = -v² / 2 (y-y₀)

a = -68 2/2 (1000-2000)

a = 2,312 m / s²

Let's use the second net law to enter the average friction force

fr = m a

fr = 97 2,312

fr = 224.3 N

b) let's look for acceleration

v² = v₀² - 2 a y

a = (v² –v₀²) / 2 (y-y₀)

a = (4² - 68²) / 2 (0-1000)

a = 2,304 m / s²

fr = m a

fr = 97 2,304

fr = 223.5 N

c) the speed of the wallet is searched with kinematics

v² = v₀² - 2 g (y-y₀)

v = √ (0-2 9.8 (0-2000))

v = 198.0 m/s

Phantasy [73]

Answer:

It will cause kinetic energy to increase.

Explanation:

Given that Speed and Motion you went from the starting line to the finish line at different rates.

If you repeated the activity while carrying weights but keeping your times the same, the weight carried will add up to the mass of the body.

And since Kinetic energy K.E = 1/2mv^2

Increase in the mass of the body will definitely make the kinetic energy of the body to increase.

Since the time is the same, that means the speed V is the same.

Weight W = mg

m = W/g

The new kinetic energy will be:

K.E = 1/2(M + m)v^2

This means that there will be increase in kinetic energy.

Which one of the following statements is true concerning the magnitude of the electric field at a point in space? It is a measur

IceJOKER [234]

Answer:

It is a measure of the electric force per unit charge on a test charge.

Explanation:

The magnitude of the electric field is defined as the force per charge on the test charge.

Since we define electric field as the force per charge, it will have the units of force divided by the unit of charge. This implies that the SI unit of electric field is given as Newton/Coulomb (N/C).

Consider the following neutral electron configurations in which n has a constant value. Which configuration would belong to the

grandymaker [24]

Answer:

he configuration with the highest electronic affinity is 2s2 2p5

Explanation:

Electronic affinity is the variation of energy when we add an electron to a neutral atom to form an ion

When an electron is added, it must occupy a space is the sub-level of the atom, giving more stability when it approaches the configuration of a complete shell with eight electrons (noble gas), so the affinity must increase when moving in a period Group VIII noble gases)

Let's examine the given settings

In this case, when adding an electron, 2s2 is very far from a complete level configuration, so its affinity must be small.

2s2 2p2 when adding an electro the one has a little more affinity, but is still a long way from a full shell, it would be missing 3 electrons

2s2 2sp5 this is the atom with the highest electronic affinity, since i = that when adding an electron the ion has the configuration of a noble gas. This is the most stable on the list

2s2 2p6 already has a full shell making it very difficult to insert an electron into this atom.

In summary, the configuration with the highest electronic affinity is 2s2 2p5
