Acceleration:</h3>
This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s²
To calculate the acceleration of the wishbone, we use the formula below.
⇒ Formula:
- F' = ma........................... equation 1
⇒ Where:
- F' = Net force between Kevin and Gamal
- m = mass of the wishbone
- a = acceleration of the wishbone
⇒ make a the subject of the equation
- a = F'/m....................... Equation 2
From the question,
⇒ Given:
- F' = 0.17 N
- m = 13 g = 0.013 kg
⇒ Substitute these values into equation 2.
- a = 0.17/0.013
- a = 13.1 m/s²
Hence, The initial acceleration of the wishbone is 13.1 m/s².

Answer:
20 m/s
Explanation:
The acceleration of an object determines the increase in velocity per second.
In this case the acceleration is 20m/s^2.
That is, the increase is 20m/s each second.
I hope this is useful for you

Answer:
there is less mass to move so the 2kg ball will move faster. the kinetic energy of the 5kg ball will move slower due to the fact that it needs more energy to move if it has more mass.
Answer:
rise the air temperature is 0.179241 K
Explanation:
Given data
mass = 20000 kg
velocity = 18.5 m/s
long = 65 m
wide = 20 m
height = 12 m
density of the air = 1.20 kg/ m³
specific heat = 1020 J/(kg*K)
to find out
how much does the air temperature in the station rise
solution
we know here Energy lost by the train that is calculated by
loss in the kinetic energy that is = 1/2 m v²
loss in the kinetic energy = 0.5 × 20000 ×18.5²
loss in the kinetic energy is 3422500 J
and
this energy is used here to rise the air temperature that is KE / ( specific hat × mass )
so here
air volume = 65 ×20×12
air volume = 15600 m³
air mass = ρ × V = 1.2 × 15600
air mass = 18720 kg
so
rise the air temperature = 3422500 / ( 1020 × 18720)
rise the air temperature is 0.179241 K
I disagree that folk dance forms can be outside their original meaningful form in this scenario.
<h3>What is Folk dance?</h3>
This is the type of dance which is unique to a particular set of people and helps celebrate their culture.
This dance is a ritualistic entertainment which is done in different type of gatherings such as ceremonies etc which is why it isn't outside their original meaningful form.
