Explanation:

Without even needing to take the average of the heights, we can glance at the histograms and notice that the vast majority of Population A's flowers are under 30 cm.

Answer:

Masę, m = 1,02 kilograma

Explanation:

Biorąc pod uwagę następujące dane;

Wysokość = 100 m

Energia potencjalna = 1 KJ = 1000 dżuli

Wiemy, że przyspieszenie ziemskie wynosi 9,8 m/s².

Znaleźć masę obiektu;

Energię potencjalną można zdefiniować jako energię posiadaną przez obiekt lub ciało ze względu na jego położenie.

Matematycznie energia potencjalna jest określona wzorem;

[tex] P.E = mgh [/tex]

Gdzie;

P.E reprezentuje energię potencjalną mierzoną w dżulach.

m reprezentuje masę obiektu.

g reprezentuje przyspieszenie ziemskie mierzone w metrach na sekundę kwadratową.

h oznacza wysokość mierzoną w metrach.

Podstawiając do wzoru, mamy;

1000 = m * 9,8 * 100

1000 = m * 980

Masę, m = 1000/980

Masę, m = 1,02 kilograma

1. Calculate the equivalent resistance in the circuit :

In the given diagram, the resistors are in series connection,

So equivalent resistance = sum of resistance of both resistors.

[tex] \large \boxed{R_{eq} =R_1 +R_2 }[/tex]

Therefore, Equivalent resistance = 840 ohms.

2. Calculate the current through the battery :

[tex] \boxed{ \mathrm{current = \dfrac{potential \: \: difference}{resistance} }}[/tex]

Hence, current through the battery = 0.142 A

3. How much current is passing through each resistor :

Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.

Answer: what is it asking

Explanation:

Answer:

f = 12 cm

Explanation:

Center of Curvature:

The center of that hollow sphere, whose part is the spherical mirror, is known as the ‘Center of Curvature’ of  mirror.

The Radius of Curvature:

The radius of that hollow sphere, whose part is the spherical mirror, is known as the ‘Radius of Curvature’ of  mirror. It is the distance from pole to the center of curvature.

Focal Length:

The distance between principal focus and pole is called ‘Focal Length’. It is denoted by ‘F’.

The focal length of the spherical (concave) mirror is approximately equal to half of the radius of curvature:

[tex]f = \frac{R}{2}[/tex]

where,

f = focal length = ?

R = Radius of curvature = 24 cm

Therefore,

[tex]f = \frac{24\ cm}{2}[/tex]

f = 12 cm

Answer:

Weight = 966 Newton.

Explanation:

Given the following data;

Length = 1.2 m

Width = 2.3 m

Pressure = 350 Pa

To find the weight of the tank;

We know that weight is the force of gravity acting on an object multiplied by its mass.

Weight = mg = force

Hence, we would determine the force using the parameters that were given.

But we would first determine the area of the rectangular tank.

Area of rectangle, A = length * width

A = 1.2 * 2.3

A = 2.76 m²

Mathematically, pressure is given by the formula;

Pressure = force/area

Force = pressure * area

Substituting into the formula, we have;

Force = 2.76 * 350

Force = 966 Newton

Therefore, the weight of the tank is 966 Newton.

Answer:

I would like to attach options to the question above for clarity.

Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct?

A. No, a weak or a strong force applied to the ball is unable to affect the motion of the ball.

B. No, the force applied to the bowling ball should be a strong force.

C. Yes, the force applied to the bowling ball affects the motion of the ball.

D. Yes, the ball will travel a longer distance when a weak force is applied.

The correct option is C (Yes, the force applied to the bowling ball affects the motion of the ball).

Explanation:

First, a force is any effort either push or pull that causes an object to undergo a change.

A bowling ball can remain at rest or in motion except a force acts on it. This brings us to the question above, the mass which affects force is not mentioned which means it is uniform or negligible. Recall that force = mass X acceleration. So the greater the force that is applied to the bowling ball the further distance it will travel. From the question, she applied a forward force (pushing), so the more force she applies the further the bowling ball will travel.

Answer:

Work done  on the two cart system is 2 N-m

Explanation:

Work done is equal to the product of force and displacement

Work done =4N * (0.17 +0.33)

work done = 4N * 0.5

Work done = 2 N -m

Work done  on the two cart system is 2 N-m

Hi,

Persuasive writing "is a sound argument of a position backed up with facts, details, examples, and one additional element-appeal".

In the choices there are only 3 answers who appeal to this definition:

1.  Banning all video games is not the answer to reducing violence in our society. People argue that violent games harm our culture and should be banned. However, this action would go against the freedom of choice.

2. The New York Times reports that over a million students in the United States are now taking courses online. Online learning may be more convenient for students and teachers. However, it appears to be just an attempt by schools to save money.

3. We must act to preserve the rain forests of the Amazon. According to the World Wildlife Fund, 17 percent of the rain forest has been cleared in the past 50 years.

Answer:

r = 50.47 x 10³ m = 50.47 km

Explanation:

Using the formula for the acceleration due to gravity:

[tex]g = \frac{Gm}{r^2}[/tex]

where,

g = acceleration due to gravity on the surface of asteroid = 0.0288 m/s²

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²

m= mass of asteroid = 1.1 x 10¹⁸ kg

r = radius of asteroid = ?

Therefore,

[tex]0.0288\ m/s^2 = \frac{(6.67\ x\ 10^{-11}\ Nm^2/kg^2)(1.1\ x\ 10^{18}\ kg)}{r^2} \\\\r = \sqrt{\frac{(6.67\ x\ 10^{-11}\ Nm^2/kg^2)(1.1\ x\ 10^{18}\ kg)}{0.0288\ m/s^2}}[/tex]

r = 50.47 x 10³ m = 50.47 km

Answer:

5.05x10^4

Explanation:

g=(GM)/r^2, so

.0288=(6.67x10^-11*1.10x10^18)/r^2, r=5.05x10^4.

This is correct on Acellus.
