A plane flying against a jet stream will travel faster than a plane traveling with a jet stream.

Answers

Answer 1
Answer:
Their "airspeeds" (speed through the air) are equal, but the one traveling in the
same direction as the jet-stream appears to move along the ground faster.

Answer 2
Answer:

FALSE, THE PLANE HAS MORE RESISTANCE THAN THE PLANE TRAVELING WITH THE JET STREAM

Answers


-- 'Ca' (Calcium) is an element.
-- The proton has a positive charge.
-- Nuclear fusion results in the synthesis of atoms of new elements.
-- H₂O (water) is a chemical compound.
-- Nuclear fission is a decay of the nucleus.
-- The atomic number of an element is the number of protons
      in each atom of it.
-- I suppose you're using the Greek letter  η  ('eta', not 'nu')
      to represent the neutron.
-- I suppose you're using ' e ' to represent the electron.

A wave has a speed of 23 m/s and a frequency of 13 Hz. What is the wavelength?

Answers

Answer:

1.76923077 meters

Explanation:

wavelength is denoted by the letter lambda it is equal to the speed (v) of a wave in a medium (air , water, light) divided by frequency , equals wavelength . so wavelength = v/f or = 23m/s ÷13hz

If you know the distance an object has traveled in a certain amount of time you can determine

Answers

With that information, you can determine the object's speed.
Just divide the distance covered by the time to cover the distance.

If you also know the direction the object moved, then you can
determine its velocity.  If you don't, then you can't.
You can determine the velocity it is moving at. 

When is acceleration the greatest on a graph

Answers

Depends on the graph, but the answer is likely the slope. The greater the slope, the greater the change in whatever is being graphed. In this case velocity vs time.

An object traveling in a straight line accelerates. What will definitely happen due to the acceleration?

Answers

"Acceleration" means any change in speed or direction of motion. 
If the object is known to be accelerating even though it's traveling
in a straight line, then we know that its speed must be changing.
