Answer:
oh this is tricky
Explanation:
this is false because the warmth of his body will transfer to the cool tiles
Object's centripetal acceleration is 20 m/s^2
An object moving in a circular path with a constant speed, does have an acceleration, as it changes its direction as the object rotates. This centripetal acceleration can be found using below mentioned relation:
Ac(centripetal acceleration) = (v^2)/r; where, v is the constant speed of object and r is the radius of circular motion
Therefore, Ac = 10*10/5 = 20 m/s2
Answer:
a= 4.4×10 m/s^2
Explanation:
pressure P = E/c
Where, E = 100 W/m^2 intensity of light
c= speed of light = 3×10^8 m/s
P = 1000/ 3×10^8
P = 3.33×10^(-6) Pa
Force F = P×A
- P is the pressure and c= speed of light
F = 3.33×10^{-6}×6.65×10(-29)
= 2.22×10^{-6}
acceleration a = F/m = 2.22×10^{-6}/ 5.10×10^{-27}
a= 4.4×10 m/s^2
Answer:
The final speed of the two carts stuck together after the collision is 1 m/s
Explanation:
This is an example of an inelastic collision where two separate carts each with different momentum collide and become a single object.
The conservation of momentum (p) equation is: where is the initial momentum of cart 1:
Notice that cart 2 is at rest, therefore its velocity is zero, which makes its initial momentum zero:
The final momentum () for which we don't know the velocity () is the product of the final mass (addition of the two masses) times the final velocity of this new object (two carts stuck together):
Now we re-write the conservation of momentum equation to isolate and obtain the unknown final velocity:
One of the main contributors to the timbre of a sound is harmonics.
