Average speed :
The horizontal (flat) line on a Distance - time graph shows that the body is at rest because the value of Distance (on y - axis ) is same for increasing time ( on x - axis ), it basically shows that the object is at the same position with the change in time.
therefore, correct option is :
The tailwind speed would actually add up to the speed of the plane.
It would blow from behind the tail of the plane.
Resultant Velocity = 20 km/h + 150 km/h = 170 km/h
Answer:
d. 60
Explanation:
If a body of mass 2 kg is moving with a velocity of 30 m/s, then
on doubling its velocity the momentum becomes
a 30 kgm/s
b 90 kgm/s
C 120 kgm/s
d 60 kgm/s

Answer:
Bronsted Lowry
Explanation:
Acid is defined as a proton donor.
While base is a proton acceptor
What is an acid An acid
An acid is a substance that donates protons or accepts a pair of valence electrons to form a bond
What is a base?
A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.
