Explanation:
What will be
the gravitational force between
two bodies if the mass of each is doubled and
the distance between them is
is halved?
Answer:
If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
BRAINLIEST? plz
NEED HELP ASAP!!! Please and thank you
Answer:
Always.
Unbalanced forces mean there will be an acceleration on the object, so speed will change no matter how fast its going already.

Whose atomic theory was the first to introduce the idea that all things are made from indivisible spheres called atoms and used evidence and research to back his findings? *
Answer:
Dalton's atomic theory
Explanation:
Dalton's atomic theory was the first to introduce the idea that all things are made from indivisible spheres called atoms and used evidence and research to back his findings. This theory was based on the law of constant composition and the law of conservation of mass. Also, this theory explains the matter in terms properties of atoms.

The graph shows the amplitude of a pausing wave over time in secondo (o).
What is the approximate frequency of the wave shown?
A. 0.5 Hz
B. 0.1 Hz
C. 9 Hz
D. 20Hz
Answer:
its B
Explanation:
i just took the test
0.1 Hz the approximate frequency of the wave shown.
What is Frequency?In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time.
After moving through a sequence of situations or locations and then returning to its initial position, a body in periodic motion is said to have experienced one cycle or one vibration. See also basic harmonic motion and angular velocity.
The frequency is 2 per second if the period, or time interval, needed to complete one cycle or vibration is 1/2 second; it is 100 per hour if the duration is 1/100 of an hour.
Therefore, 0.1 Hz the approximate frequency of the wave shown.

How do you calculate the magnitude of the resultant force of two
forces acting on an object in the same direction?
Answer:
Two forces that act in opposite directions produce a resultant force that is smaller than either individual force. To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force.
To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right, and a force of 3 N act to the left. Calculate the resultant force.

What is lense ?A lens is a transmissive optical device that employs refraction to concentrate or scatter a light beam. A simple lens is made up of a single piece of transparent material, whereas a compound lens is made up of numerous simple lenses organized along a common axis.
For lenses
A converging lens, also known as a convex lens, has a positive focal length (f > 0). It is a lens that, after passing through it, focuses parallel beams of light.
A diverging lens, commonly known as a concave lens, has a negative focal length (f 0). It is a lens that spreads parallel beams of light after they pass through it.
For mirrors
A concave mirror has a positive focal length (f > 0). It is a mirror that focuses parallel beams of light in front of it.
A convex mirror has a negative focal length (f 0). It's a mirror that spreads out parallel beams of light as though they're originating from a virtual focal point behind the mirror.

A dolphin can hear sounds with frequencies up to 280 kHz. What is the
speed of sound in water if a wave with this frequency has a wwavelength
of 0.51 cm?
Answer:
1428 m/s
Explanation:
Given that,
The frequency hear by a dolphin, f = 280 kHz
We need to find the speed of sound in water if a wave with this frequency has a wavelength of 0.51 cm.
The formula for the speed in terms of wavelength and frequency is given by :
[tex]v=f\lambda\\\\v=280\times 10^3\times 0.51\times 10^{-2}\\\\v=1428\ m/s[/tex]
So, the speed of sound in water is 1428 m/s.
