Answer:

division is (uncountable) the act or process of dividing anything while separation is the act of disuniting two or more things, or the condition of being separated.

Separation is the propagation method in which these natural structures are simply removed from the parent plant and planted to grow on their own. When one of these structures is cut into sections that will then grow into a new plant the method is referred to as division.

What is the charge on an object that has 1.09x10^13 excess electrons?

Nadya [2.5K]

Answer:

$-1.74\cdot 10^{-6} C$

Explanation:

The electron is the particle that rotates around the nucleus of the atom; it has a negative electric charge equal to :

$e=-1.6\cdot 10^{-19}C$

which is known as fundamental charge.

For an object containing N excess electrons, the total charge of the object is

$Q=Ne$

In this problem, the number of excess electrons in the object is:

$N=1.09\cdot 10^{13}$

Therefore, by plugging it the numbers, we can find the value of Q, the total charge of the object:

$Q=(1.09\cdot 10^{13})(-1.6\cdot 10^{-19})=-1.74\cdot 10^{-6} C$

Choose all of the statements that are true about electromagnets: 1. Electromagnets are permanent and always have a magnetic fiel

Nitella [24]

Answer:

2. electromagnets can be made stronger by adding more coils to the solenoid.

3. electromagnets can be made stronger by increasing the strength of the electrical source.

Explanation:

Electromagnets are not permanent, they act as magnets when current runs through its coils. They can be stronger by increase the current that goes through the coil surrounding them,. This can be done two ways: 1) increasing the actual current intensity, or 2) increasing the number of coils that wrap around them.

. A 24-V battery is attached to a 3.0-mF capacitor and a 100-ohm resistor. If the capacitor is initially uncharged, what is the

Licemer1 [7]

Answer:

The voltage is $V_c = 9.92 \ V$

Explanation:

From the question we are told that

The voltage of the battery is $V_b = 24 \ V$

The capacitance of the capacitor is $C = 3.0 mF = 3.0 *10^{-3} \ F$

The resistance of the resistor is $R = 100\ \Omega$

The time taken is $t = 0.16 \ s$

Generally the voltage of a charging charging capacitor after time t is mathematically represented as

$V_c = V_o (1 - e^{- \frac{t}{RC} })$

Here $V_o$ is the voltage of the capacitor when it is fully charged which in the case of this question is equivalent to the voltage of the battery so

$V_c = 24 (1 - e^{- \frac{0.16}{100 * 3.0 *10^{-1}} })$

$V_c = 9.92 \ V$

A 86 kg human stands on the surface of Venus. The mass of Venus is 4.9 × 1024 kg and its radius is 6.1 × 106 m. Collapse questio

iris [78.8K]

Answer:

755.37 N

Explanation:

We are given that

Mass of venus= $m_1=4.9\times 10^{24}kg$

Radius= $r=6.1\times 10^6$ m

Mass of human= $m_2=86 kg$

We know that the gravitational force between two bodies

$F=G\frac{m_1m_2}{r^2}$

Where G=Gravitational constant= $6.67\times 10^{-11}Nm^2/kg^2$

Using the formula

The magnitude of the gravitational force exerted by Venus on the human= $F=\frac{6.67\times 10^{-11}\times 86\times 4.9\times 10^{24}}{(6.1\times 10^6)^2}$

The magnitude of the gravitational force exerted by Venus on the human=F= $755.37N$

if the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspe

Mazyrski [523]

If the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspeed will Increase and true altitude will increase.

<h3>What is Altitude?</h3>

This refers to the vertical elevation of a body and is the measurement of the height above the sea or ground level. An airplane's altitude is directly proportional to the airspeed as long as the power is constant.

This means that increase in airspeed will lead to an increase in altitude and vie versa. This is the reason why as it runs fast, it can be observed that it begins to elevate.
