When an object undergoes uniform acceleration, its velocity changes by the same amount per unit of time.
For example, a person jumping off a cliff into a pool of water below undergoes a uniform acceleration of approximately 9.81m/s². This means that, for every second that passes, the person's downward velocity increases by 9.81m/s
Answer:
protons
Explanation:
protons has always positive charge
Answer:
The statement is TRUE
Explanation:
computer programs like spreadsheets can be used to help organize and analyze data. Regression Analysis can be carried out in Excel to determine the relationship between two quantitative variables.
B. A sandbar is formed by water. A sand dune is formed by wind.
Answer
given,
speed of car = 60 km/hr
= 60 x 0.278 m/s
= 16.68 m/s
radius of the tire = 25 cm = 0.25 m
time taken to stop = 6 s
average acceleration = ?
average acceleration=
=
= 11.12 rad/s²
correct answer option D
b) length of sea saw = 10 m
mass of jack = 100 Kg
mass of Jill = 60 Kg
Let y be the distance from the Jack. To balance the seesaw moment on both side should balance each other about fulcrum
now,
100 x y = 5 x 60
y = 3 m
the correct answer is option B
