Which are examples of a medium? water and air amplitude and wavelength crests and troughs compressions and rarefactions
umka21 [38]

Answer:

water and air

Explanation:

  • A wave is a transmission of a disturbance from one point or the source to another  point.
  • Transmission of a wave occurs through a material medium or a vacuum. Therefore a medium is the material through which a wave travels through.
  • The medium may be in gaseous form, slid form or liquid form. Therefore water and air are example of medium of transmission of a wave.

1 . W=mass times acceleration due to gravity
60kg times 9.8m/s2
= 588N

2. W=mg
1176N=m times 9.8
m=120kg


3. 1 hour=3600s
24 hours=?
24 times 3600
= 86400 seconds


4. 1000g=1kg
25000g=?
25000 times 1 divide by 1000
=25kg



5. 1000000mg=1kg
123000000=?
123000000 times 1 divide by 1000000

A 5.0kg toolbox is raised from the ground by a rope. If the upward acceleration of the bucket is 2.5 m/s^2, find the force exert
swat32

Answer:

62 N

Explanation:

Sum of the forces on the toolbox:

∑F = ma

T − mg = ma

T = mg + ma

T = m (g + a)

T = (5.0 kg) (9.8 m/s² + 2.5 m/s²)

T = 61.5 N

Rounded to two significant figures, the force exerted by the rope is 62 N.
