Answer:

  • <u>Translated from Spanish language:</u>

"As part of a vertical shooting test a rock is thrown, with an ancient Roman catapult, vertically upwards with an initial speed of 100m / s."                                                                                                                    

Explanation:

  • As, the motion can be termed as  more of a projectile form, while the initial velocity of the projectile or the body in motion is about a 100m/ s. We can easily determine the final velocity, Vf of the body by the following equation given as follows.
  • And, let say that the initial time taken is about 2 seconds.So, we can put the values of the gravity, along with the time,t in the following equation and get a valid result for all of this in a more proper way.
  • Vy= V(x)- gt, ⇒ V(y)= 100- (9.8)×(2 seconds),
  • V(y)= 80.4 m/sec.  <u>"</u><u>Answer"</u>

PLEASEE I NEED HELP FAST!!! .Study the scenario.A small container of water with a low temperature is poured into a large contain
RSB [31]

Answer:

that best describes the process is C

Explanation:

This problem is a calorimeter process where the heat given off by one body is equal to the heat absorbed by the other.

Heat absorbed by the smallest container

             Q_c = m ce (T_{f}-T₀)

Heat released by the largest container is

              Q_a = M ce (T_{i}-T_{f})

how

        Q_c = Q_a

       m (T_{f}-T₀) = M (T_{i} - T_{f})

Therefore, we see that the smaller container has less thermal energy and when placed in contact with the larger one, it absorbs part of the heat from it until the thermal energy of the two containers is the same.

Of the final statements, the one that best describes the process is C

since it talks about the thermal energy and the heat that is transferred in the process

When a boy jumps into a pool ​
melomori [17]

<u>Answer:</u>

energy only

<u>Explanation:</u>

Water waves transfer energy via oscillations of the water molecules, but the the water molecules themselves do not move along the wave.

This is why when the boy jumps into the water, his kinetic energy is transferred by the water molecules across the pool, but neither the boy nor the water particles move along with the wave.

To Which of the following represents the relative order of wavelengths from least
Alex787 [66]

Answer:

A) ultraviolet light ---> violet light ----> red light-----> infrared light

Explanation:

We know that the electromagnetic spectrum with the wavelength from least to greatest is (also refer attachment)

  • gamma ray
  • X- rays
  • Ultra-violet
  • Visible            

                  Violet

                  Indigo

                  Blue

                  Green

                  Yellow

                   Orange

                   Red

  • Infra-red
  • Microwave
  • Radio wave

Hence the relative order of wavelengths from least to greatest in the electromagnetic spectrum is

    A) ultraviolet light ---> violet light ----> red light-----> infrared light
