Answer:

Product of masses and square of the distance them.

Explanation:

The gravitational force between two objects is given by :

[tex]F=\dfrac{km_1m_2}{r^2}[/tex]

The two characteristics that determine the strength of the gravitational force between two objects are :

1. The product of masses of two objects

2. The distance between the charges

Answer:

B) 2.45 m/s^2 ( not sure i just search it )

Explanation:

F = k |q1| |q2| / r^2

k = 9 * 10^9

q1 = - 2.5 C

q2 = 2 C

r = 100

r^2 = (10^2)^2 = 10^4

F = (9*10^9) * ( 2.5 ) ( 2) / ( 100)^2

F = 45* 10^9 / 10^4

F = 45 * 10^9 * 10 ^ -4 = 45 * 10^5 N

F = 45 * 10 ^ 5 N

Answer:

a. temperature of the substance increases.

Explanation:

Temperature is defined as a measure of the average kinetic energy of a substance, so as one rises, so will the other. They are directly proportional.

As the kinetic energy of the molecules in a substance increases, the temperature of the substance is also increases because kinetic energy and temperature is proportional to each other.

Kinetic energy is directly related to temperature which means if kinetic energy is increased, the temperature of the solution is also increased and vice versa.

So we can conclude that As the kinetic energy of the molecules in a substance increases, the temperature of the substance is also increases because kinetic energy and temperature is proportional to each other.

Answer:

D

Explanation:

speed = frequency x wavelength

speed of light in vacuum is 3.0 x 10^8

wavelength = 5.32 x10 ^-7

3.0 x 10 ^ 8 = 5.32 x 10^-7 x frequency

frequency = 5.63909 x 10^14

round it off = 5.64 x 10^14 Hz

thus the answer is D

hope this helps please mark it

Answer:

L = 6 m n = 3 f = 45/10 = 4.5 Hz → T = 1/f = 0.22 s

wavelength = 2L/n = 2×6÷3= 4 m

speed(v) = wavelength × f = 4×4.5 = 18 m/s

Explanation:

second solution for frequency:

f= speed(v) / wavelength = nv/2L = 3×18÷(2×6) = 4.5 Hz

Answer:

A. 2.5 mm

B. 0.25 cm

Explanation:

A. Determination of the thickness of the wire.

Number of turns (n) = 10 turns

Length (L) = 25 mm

Thickness (T) =?

T = L / n

T = 25 / 10

T = 2.5 mm

Thus, the thickness of the wire is 2.5 mm

B. Determination of the thinkness in centimetres (cm).

Thickness (in mm) = 2.5 mm

Thickness (in cm) =?

Recall:

10 mm = 1 cm

Therefore,

2.5 mm = 2.5 mm × 1 cm / 10 mm

2.5 mm = 0.25 m

Therefore, the thickness of the wire in centimetre (cm) is 0.25 cm

Answer:

adaptive optics.

Explanation:

Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

A lens can be defined as a transparent optical instrument that refracts rays of light to produce a real image.

A telescope can be defined as an optical instrument or device which comprises of a curved mirror and lenses used for viewing distant objects i.e objects that are very far away such as stars and other planetary bodies.

The technique called adaptive optics uses a high-speed computer to monitor atmospheric distortion and adjust the optics of a telescope to partially compensate for the seeing.

Basically, adaptive optics is used by astronomers to correct the distortions caused by the turbulence of the atmospheric conditions of the Earth in real-time, so as to have an image that is as sharp as anyone taken in space.

30 m/s

Explanation:

Vf = ?

Vi = 0 m/s

a = 20 m/s^2

Plug those values into the equation: Vf = Vi + at

Vf = 0 + (20)(1.5)

Vf = 30 m/s

Answer:

Red shift supports the big bang theory. ... The light from distant galaxies is red shifted (this tells us the galaxies are moving away from us) and the further away the galaxy the greater the red shift (this tells us that the more distant the galaxy the faster it is moving). Constellations look like they are moving because earth is rotating on it's axis.

The title is the journey of the ice cube. (change it if you want)

Main character - ice cube

There was an ice cube made by the water from the freezer in an ice shop.

The ice cube, with a bunch of other ice cubes, were taken to be packed and sold to a restaurant. The ice cube was excited to where he was going while the other ice cubes are just meh. Now that the ice cubes arrived, a restaurant worker stores the ice cubes in a cooler and later used to put ice in a lemonade. While the lemonade in a glass cup was carried outside the porch of the restaurant by the waiter, the ice cube was fascinated by the environment of the restaurant. The waiter finally serves the thirsty customer and the customer drank almost half of the lemonade but the ice cube did not get in the man's mouth. Instead the other ice cubes went. The ice cube feared the person. Shortly after checking his phone, the customer was about to reach on to the glass until the hands accidentally pushes the glass over and falls. The ice cube and the remaining ice cubes spread away with the wasted lemonade liquid. No one bothered cleaning up the ice cubes, only the glass shards because the floor is a smooth concrete. Outside was really hot from the sun anyways so it would melt the ice cube and sooner evaporate. As it was in liquid form, the "ice cube" was feeling relaxed because it was just chilling on the floor. And when it evaporates, the ice cubes becomes more fascinated since it goes up to the sky while having a sky-view from above.

That is the end.

Answer:

Pressure = 24000 N/m²

Explanation:

Given the following data;

Force = 120N

Area = 0.5cm² to meters = 0.5/100 = 0.005 m²

To find the pressure;

Pressure= force/area

Pressure= 120/0.005

Pressure = 24000 N/m²

Therefore, the pressure on the archer's fingers is 24000 Newton per meters square.

The pressure on the archer's finger will be  [tex]P=240 \ \frac{N}{cm^2}[/tex]

Pressure is defined as the normal force applied to the particular area. The formula is given as

[tex]P= \dfrac{F}{A}[/tex]

Here

F= Force applied

A= Area at which the force is applied

Now it is given that

F= 120 N

A= 0.5 [tex]cm^2[/tex]

Now by putting the values in the formula we get

[tex]P=\dfrac{120}{0.5} =240\ \frac{N}{cm^2}[/tex]

Thus the pressure on the archer's finger will be  [tex]P=240 \ \frac{N}{cm^2}[/tex]

Answer:

Force = 304.5 Newton

Explanation:

Given the following data;

Initial velocity, u = 0m/s (since it started from rest).

Final velocity, v = 42m/s

Time, t = 0.02 secs

Mass = 0.145 kg

To find the force;

First of all, we would have to determine the acceleration of the ball;

Acceleration = (v - u)/t

Acceleration = (42 - 0)/0.02

Acceleration = 42/0.02

Acceleration = 2100 m/s²

Now, we solve for the force;

Force = mass * acceleration

Force = 0.145 * 2100

Force = 304.5 Newton
