Answer:
W=1.5×10⁸J
Explanation:
first change the km to m then you get 10000m
- W=Fd
- W=15000*10000
- W=1.5×10⁸J
Answer:
Transverse waves oscillate perpendicular to the direction of the wave (e.g. any electromagnetic wave like radiowaves, x-rays...) whilst compressional waves oscillate in the same direction of the wave (e.g. sound waves)
Explanation:
The position of the car at t=3.0s is 18m from the origin.
the starting point of a quantity at a certain time, let's say t = 0. This is referred to as receiving an "initial condition",
For a car on an amusement park ride, the velocity as a function of time is given by v=at² + bt with constants.
According to the equation above,
- A function of time's derivative is a constant.
- Time affects the velocity.
v = t² + 2t
Since v = dx/dt
dx/dt = t² + 2t
dx = t²dt + 2tdt
Integrating both sides [ integration{ a^nda } = a^(n+1) / (n+1) ]
So , int [ x⁰dx ] = int [ t²dt ] + 2 int [ t¹dt ] ,
Now,
x¹/1 = t³/3 + 2*( t²/2 )
x = t³/3 + t²
For t = s,
x = 3³/3 + 3²
x= 27/3 + 9 = 18 m .

Momentum = mass*velocity
In variable form, this is the same as p=mv.
Therefore:
22,000=1,100v
v = 20 m/s
The Jovian planets contain large percentage of Gases its because they are formed outside of what they called as frost line where temperature is low enough for ice condensation unlike terrestrial planets formed close to the sun where the temperature is very appropriate for metal and rock to condense.
