Answer:
Magnitude of the acceleration(g) = 9.7 meters/second²
Explanation:
Given:
Height of tower = 56 meter
Time taken = 3.4 second
Final velocity (v) = 33 meters/second
Initial velocity (u) = 0 meters/second
Find:
Magnitude of the acceleration(g)
Computation:
Using first equation of motion:
v = u + at
Magnitude of the acceleration(g)
v = u + gt
33 = 0 + g(3.4)
g = 33 / 3.4
g = 9.7 meters/second²
Magnitude of the acceleration(g) = 9.7 meters/second²
Answer:
The charge is
Explanation:
From the question we are told that
The mass of each ball is
The distance of separation is
Generally the weight of the each ball is mathematically represented as
where g is the acceleration due to gravity with a value
substituting values
Generally the electrostatic force between this balls is mathematically represented as
given that the the charges are equal we have
So
Now from the question we are told to find the charge when the weight of one ball is equal to the electrostatic force
So we have
=>
The rock will sink.
The density of water is 1.0g/cm^3
The density of the rock is 1.73g/cm^3
a.) Relative velocity = velocity of car B - velocity of car A
= 19 - 14
= 5 m/s
Hope this cleared your doubt, feel free to ask any question regarding this and have a nice day ahead! :)
