are clocks permanently stuck to walls?
Answer:
It depends
Explanation:
what is this question
Answer:
No...
Explanation:
I think this may be a trick question... so from my reasonable logic, I'm gonna say no because more often then not they are attached to the wall with nails/screws. Or they are hanging.
So they could come off. Also if someone was desperate, they could always grab a chainsaw and force it off of the wall. Not a great idea though, then the wall would be broken!! Most likely the clock too!
How efficent is geothermal at producing eletricity?
Answer:
The conversion efficiency of geothermal power developments is generally lower than that of conventional thermal power plants. ... The highest reported conversion efficiency is approximately 21% at the Darajat vapour-dominated system, with a worldwide efficiency average of around 12%.

Waves propagate along a stretched string at a speed of 8.0 m/s. The end of the string vibrates up and down once every 1.5 s. What is the wavelength of the waves traveling along the string?
Answer:
So we have waves F= 1/t So F= 1/1.5= 0.66V= wavelength × F 8.0m/s= x × 0.66x=12.2The wavelength of the waves traveling along the string is 12 meters.
What is a Wavelength?
The distance between adjacent successive crests or troughs of a wave is termed as its wavelength. Wavelength is calculated in the wave's direction.Given:
Waves propagate along the stretched string at speed = 8.0 m/s
The end of the string vibrates up and down once every 1.5 s.
∴ Time = 1.5 s
We have to find the wavelength of the waves.
We know,
⇒ Time = 1/frequency
⇒ 1/frequency = 1.5
Now
⇒ speed = frequency × wavelength
⇒ wavelength = speed / frequency
⇒ wavelength = 8 × 1.5
⇒ wavelength = 12 m
Therefore, the wavelength of the waves traveling along the string with given speed is 12 m.

Athlete mesert defar runs at 10m/s. how long will it take her to go 1 minute
Answer:
600 metres
Explanation:
1 minute = 60 seconds
1 second = 10 metres
60 seconds = 60 x 10 = 600
Athlete Mesert Defar runs 600 m in 1 minute. The speed of an object is equal to the distance traveled divided by time elapsed.
What is the relationship between Speed and Distance?The speed of an object is equal to the distance traveled divided by time elapsed.
[tex]s = \dfrac dt \rm \ \ \ or[/tex]
[tex]d = s \times t[/tex]
Where,
[tex]d[/tex] - distance
[tex]t[/tex] - times = 1 minute = 60 sec
[tex]s[/tex] - speed = 10 m /s
Put the values in the formula,
[tex]d = 10 \times 60 \\\\ d = 600 \rm \ m[/tex]
Therefore, Athlete Mesert Defar runs 600 m in 1 minute.

A man is attempting to push a chair across the floor exerting a force of 50 N .When will the chair exert a force of 50 N on the man?
Answer:
ALWAYS ( in all cases and at all times)
Explanation:
From Newton's 3rd Law of motion which states that every action that occurs (force) there will be equal as well as opposite reaction. Therefore as the man is pushing the chair exerting 50N force, the chair also is is exerting equal force as well as opposite force on him as he is pushing it

the gravitational force between the sun and earth is larger than sun and the moon. what do you think the reason for this is?
Answer: The greater an object's mass, the more gravitational force it exerts.
Explanation: So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. Sorry if I get this wrong. I am in 5th grade! ♥
The gravitational attraction between the Sun and Earth is stronger than the attraction between the Sun and the Moon, principally because of the Sun's greater mass and greater distance from Earth.
An object's mass affects how much gravitational pull it exerts. Both the Earth and the Moon are much less massive than the Sun. Approximately 330,000 times more massive than the Earth, and roughly 27 million times more massive than the Moon, is the Sun. Because of the Sun's greater mass, its gravitational pull is thus much stronger.
The strength of the gravitational force between two objects is greatly influenced by their distance from one another. The Sun and Earth are separated from one another by a far smaller distance than the Sun and Moon. The Sun is located roughly 150 million kilometers from Earth, while the Moon is located roughly 384,400 kilometers from the Sun on average. The inverse square law asserts that the gravitational force decreases with increasing distance, and that it is only one-fourth as strong when two objects are twice as far apart.
Hence, the gravitational force between the sun and earth is larger than the sun and the moon due the mass of the sun and earth is greater than the moon and sun. The distance between the sun and the earth is comparatively smaller than the distance between the sun and the moon.

If a car has traveled 24 km in 2 hours, what is its average speed?
Answer:
12km per hour
Explanation:
The formula is distance/time.
24km/2 hours = 12km/1 hour
Explanation:
average speed = distance / time
= 24km/ 2 hr
= 12 km/ hr

Calculate the force applied (in newtons) if a pressure of 7Pa is acting on an area of 21m?.
Answer:
147N
Explanation:
pressure = 7pa
area= 21m
force=?
now,
p = f/a
7 = f/21
f = 21×7
therefore, f = 147N.
When a warm object is heated up, the thermal radiation it emits changes. Give two ways in which the thermal radiation changes
Answer:
*The increase in thermal energy the maximum emission of radiation changes according to Wien's law
*The increase in thermal energy he intensity of the energy increases significantly, proportional to the fourth power of the temperature
Explanation:
When bodies heat up, the vibrations of their molecules and atoms increase, due to the energy, therefore the internal energy (Temperature) of the body also increases.
The increase in thermal energy relaxes in an increase in body temperature, when this happens the maximum emission of radiation changes according to Wien's law that gives a shift towards the visible as the temperature increases.
Furthermore, the intensity of the energy increases significantly, in a curve described by the Planck expression.
These increases are proportional to the fourth power of the temperature

a truck starts from rest and accelerates for 25 seconds to reach a velocity of 60m/s . calculate the rate of acceleration for the truck
Answer:
2.4m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Time 25s
Final velocity = 60m/s
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of displacement
Acceleration = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
Acceleration = [tex]\frac{60 - 0}{25}[/tex] = 2.4m/s³

Why do we see Moon phases?
Answer:
The moon its self does not generate life.
Explanation:
Moon phases are determined by the relative positions of the Moon, Earth, and Sun. Instead, the Moon's phase depends only on its position relative to Earth and the Sun. The Moon doesn't make its own light, it just reflects the Sun's light as all the planets do. The Sun always illuminates one half of the Moon.

Abdul works at the planetarium where he is responsible for creating a show on stars. His show is entitled "A Star is Bom," and it will explain the
forces that create a star.
Abdul is creating a timeline of a star's life including its beginning, middle, and end. Abdul found a picture to include of the region around a star
before its formation begins. What does it look like?
Answer:
dust cloud
Explanation:
Stars are formed from the accumulation of the dust as well gases in the solar system. The dust and the gases collapses due to the the gravity forces and the stars are formed.
They are formed within the clouds of the dust and gases and are scattered in the galaxies. The stars are formed in a million of years from the dust clouds.
In the context, Abdul have a picture of a dust cloud which looks smoky and dusty which is the initial stage of the stars formation due to the gravity. It is the region of the star that looks like a cloud of dust before the formation of the star.
