Answer:

The charge on the second particle is defined as

q_2 = 1.74 \times 10^{-18} C

Explanation:

It is known that the force existence between two charges is expressed as

F = \frac{kq_1q_2}{r^2}

It is given that

F = 7 N

r = 0.31 \mu m

q_1 = 4.3 \times 10^{-5} C

At this juncture, we find that

7 = \frac{9 \times 10^9 (4.3 \times 10^{-5}q_2}{(0.31\times 10^{-6})^2}

Now we ascertain

q_2 = 1.74 \times 10^{-18} C

Determine the mass of a ball with a velocity of 40.0 m/s and a wavelength of 8.92 Ã 10-34 m.
Sav [3153]
The wavelength can be calculated as Planck's constant divided by the momentum of the ball.
This translates to:
lambda = h / p.............> equation I
Momentum is equal to mass times velocity............> equation II

By substituting equation II into equation I, we obtain:
lambda = h / mv
Here are the values provided:
lambda = 8.92 * 10^-34 m
Planck's constant = 6.625 * 10^-34
velocity = 40 m/sec

Substituting these values into the previous equation, we calculate the mass as follows:
8.92*10^-34 = (6.625*10^-34) / (40*m)
mass = 0.0185678 kg

Calculate the minimum average power output necessary for a person to run up a 12.0 m long hillside, which is inclined at 25.0° a
Ostrovityanka [3204]

Answer:

Power output, P = 924.15 watts

Explanation:

We have the following parameters:

Length of the ramp, l = 12 m

Weight of the individual, m = 55.8 kg

Incline angle with respect to the horizontal, \theta=25^{\circ}

Elapsed time, t = 3 s

Let h represent the vertical height of the hill:

h=l\ sin\theta

h=12\times \ sin(25)

h = 5.07 m

Power P required for a person to ascend the hill can be expressed as:

P=\dfrac{E}{t}

P=\dfrac{mgh}{t}

P=\dfrac{55.8\times 9.8\times 5.07}{3}

P = 924.15 watts

This indicates that a minimum average power output of 924.15 watts is essential for an individual to ascend this elevation. Thus, this is the answer sought.

Jay collects eggs in a basket and weighs the basket. He graphed the relationship between the number of eggs
serg [3582]

Answer:

I'm having difficulty comprehending the figures you've presented, but I will attempt to address the inquiry.

Jay is gathering data on the weight of a basket in correlation to the number of eggs it holds.

For a single egg, he notes that the basket weighs w1

for two eggs, the basket weighs w2

and continues similarly.

In this context, a linear relationship can be established as:

Weight = number of eggs*k + b

Where k denotes the slope and b refers to the y-intercept.

k signifies the average weight of each egg, while b marks the initial weight of the basket.

Sully is riding a snowmobile on a flat, snow-covered surface with a constant velocity of 10 meters/second. The total mass of the
inna [3103]
Result: 168N

The calculation shows 16 - 10 equals 6
and 6 divided by 10 equals 0.6
. Therefore, F equals 280 multiplied by 0.6 equals 168.

The image illustrates that as the distance between two objects increases, the force of gravity ____________. A) decreases. B) in
Sav [3153]
The image is absent (but it's not essential to resolve the issue).

The right response is A) decreases, as gravitational force is inversely related to the square of the distance. The magnitude of the gravitational force between two masses M and m, separated by a distance d, is expressed as
F=G \frac{Mm}{d^2}
where G is the gravitational constant. The formula demonstrates that as the distance d between the two masses increases, the force magnitude diminishes.
