Answer:

The carriage has the energy, W = 2469.6 J

Explanation:

Given data,

The height of the hill, h = 21 m

The carriage with the baby weighs, m = 12 kg

The energy possessed by the body due to its position is the potential energy,

                                      <em>W = P.E = mgh joules</em>

Substituting the values,

                                       W = 12 x 9.8 x 21

                                            = 2469.6 J

Hence, the carriage has the energy, W = 2469.6 J

What equation/formula would you use to find the distance an object traveled?
Rudik [331]

Answer:

a. distance = s x t

Explanation:

The equation we know for speed is speed = distance/time, shortened to s = d/t

If you want to find the distance, you'd rearrange the formula to make d the subject. To isolate d, multiply by t on both sides (since it's being divided on the right. This leads to

s x t = d, with d isolated on the right side.

Therefore, to find the distance an object travelled you'd use a. distance = s x t

Ket [755]
  • Height=h=21m
  • Mass=m=12kg

\\ \rm\longmapsto P.E=mgh

\\ \rm\longmapsto P.E=12(10)(21)

\\ \rm\longmapsto P.E=120(21)

\\ \rm\longmapsto P.E=2520J

What are the benefits and harms of protists? WILL GIVE BRAINLIEST FOR THE PERFECT ANSWER
alina1380 [7]

Answer:

<em>Well, Many protists are harmful to humans, other animals and plants because they cause diseases and crop failures. However, some protists are actually beneficial to other creatures and are used by humans for various purposes. Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Hope That Helps!</em>
