Answer:
The mass=0.169
The height=57.8
The power=1.63 watts
Explanation:
The formula for mass is 2KE/v^2
v=34×34 KE=98 therefore 2*98/34^2=0.169
The formula for height is v^2/2g
v=34*34 therefore 34^2/2*10=57.8
The formula for power is work/time
in which the work is the kinetic energy =98
and time 1*60secs =60 therefore 98/60=1.63watts

If the distance to the water level in the well is doubled, is the time until you hear the splash twice what it was before, more than twice, or less than twice?
Echo is a reflection of sound waves. If the distance is increased, we hear the sound in more than twice the former time.
What is echo?The term echo has to do with the reflection of sound waves. We know that when sound waves are reflected, we hear the sound as the echo.
Now, the time that it takes us to hear the echo depends on the distance between the observer and the depth of the well. If the distance is increased, we hear the sound in more than twice the former time.

hears a 1920
1920 Hz sound when it drives
away from the stationary police car.
How fast is the second car driving?
Answer: 15.35 m/s
Explanation: 15.35 m/s
[tex]$$From the Doppler effect$$f^{\prime}=\left(\frac{v \pm v_{0}}{v \pm v_{s}}\right) f_{s}$$[/tex]
[tex]\begin{aligned}&f^{\prime}=1920 \mathrm{~Hz} ; \ \ V=343 \mathrm{~m} / \mathrm{s} \\&f=2010 \mathrm \ \text{{H}z} \\&V_S=0 \text { As police car is stationary }\end{aligned}[/tex]
[tex]\begin{aligned}1920 &=\left(\frac{343 \pm v_{0}}{343}\right) \times 2010 \\1920 &=\left(\frac{343-v_{0}}{343}\right) \times 2010 \\ -v_{0} &=-15.35 \mathrm{~m/s} \\v_{0} &=15.35 \mathrm{~m} / \mathrm{s}\end{aligned}[/tex]

A loaded spring undergoes simple harmonic motion whose period is proportional to the mass and inversely proportional to the spring constant.
What is simple harmonic motion?Simple harmonic motion is the periodic motion of an object along a straight line, such that the acceleration of the object is directed towards a fixed point on that line and is proportional to its distance from that point.
Example of a simple harmonic motion is the motion of a loaded spiral spring.
The restoring force on the spring is directly proportional to the extension of the spring and the spring constant.
The period of motion, T when a mass, m is attached to a spring with spring constant k,is given as:
T = 2π√(m/k)Therefore, a loaded spring undergoes simple harmonic motion whose period is proportional to the mass and inversely proportional to the spring constant.

An object is at rest on a tabletop. Earth pulls downward on this object with a force equal in magnitude to mg. What is the interaction pair to this force
Answer:
normal contact force
Explanation:
that is the equal and opposite force (as to weight) applied by the table on to the object.
The gravitational force of the earth on the object and the reaction force of the table on the object interact as a pair of forces.
What does gravity mean?The gravitational force is what pulls things with mass in the same direction. People commonly think about the Earth's gravitational pull. Your body is kept on the ground by this force. Yet, gravity pulls all objects with mass in the same direction.
The gravitational force, or g, is the force that the earth exerts on an object, with g equal to 9.8 m/s2.
The information is ,
Place something on the table.
Now that the item is at rest, a force known as gravitational force pushes it downward from the Earth.
The formula for gravitational force is F = mg, where m is the object's mass.
Moreover, Newton's third law states that every action will always have a corresponding and opposing reaction. When the gravitational force acting between two masses is equal in strength and conducted in the opposite direction, an action and reaction pair is produced.
The reaction force is then given by R = -mg, where m is the object's mass and the negative sign denotes that the force is acting in the opposite direction to that of gravity by earth.
Hence , the interaction pair for gravitational is the reaction force

Sample Response: When there is less rainfall, land, which is part of the geosphere, becomes dry. When there is not enough water, plants will not get the nutrients they need from the soil and animals will not get enough water, and they will die. Both plants and animals are part of the biosphere. Less precipitation would also mean less water in lakes and groundwater, parts of the hydrosphere, and less evaporation.

On top a coiled spring labeled wave a with coils, which are widely spaced then tightly spaced then widely space. on bottom a coiled spring labeled wave b with coils, which are widely spaced then very tightly spaced then widely space. which statement can be made about waves a and b? wave a has a lower amplitude than wave b. wave a has a higher amplitude than wave b. wave a has a lower frequency than wave b. wave a has a higher frequency than wave b.
Answer:
Wave A has a lower frequency than Wave B.
Explanation:
Frequency is the number of waves passing through the unit time.
As the statement of the question says that the coils in wave A are widely and tightly spaced.
While in wave B the coils are widely and very tightly spaced which means the number of coils is more and the frequency of wave B is more than wave A.
Therefore more coils will pass through a fixed point in unite time and more will be the frequency.
Answer:Wave A has a lower frequency than Wave B.

What is the function (job) of the genes in protein synthesis (how proteins are made in the cell)?
Answer:
Most genes contain the information needed to make functional molecules called proteins. A few genes produce regulatory molecules that help the cell assemble proteins.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
