Assuming constant acceleration, the distance travelled in the first 4.5s is:
0.5*5.0*4.5 = 11.25m
The distance travelled in the next 4.5s is:
5.0*4.5 = 22.5m
The total distance travelled is:
11.25 + 22.5 = 33.75m
Answer:
Combustibility is a measure of how easily a substance bursts into flame, through fire or combustion. This is an important property to consider when a substance is used for construction or is being stored. It is also important in processes that produce combustible substances as a by-product.
Explanation:
Answer:
h=17m
v=18.6 m/s
Explanation: The question can be solved by applying kinematic equations of motion
Data
u=0
a=g
t=1.9 secs
firstly to calculate the height
to find the final velocity
The acceleration graph is straight line of equation y=9.8 as acceleration is constant:
Velocity graph is given by y=9.8x ( y as velocity and x as time):
Displacement graph is given by y=4.9x^2 ( x as time, y as displacement):
These graphs are only applicable from x=0 to x=1.9 ... ignore the other graph sections
Answer:
Explained
Explanation:
i)Two spheres hanging from nylon threads attract each other because either the two spheres are charged with opposite sign or only one of the spheres is charge so the other would be charge by induction of the charged sphere and hence attract each other.
ii)However, when they are touched the charges will be rearranged among the two sphere such that the two sphere have exact same magnitude and sign of charge and now they will repel each other or the magnitude of charges on the two spheres become zero and they neither attract or repel each other.
The city monitors the steady rise of CO from various sources annually. In the year "C: 2019"<span> (rounded off to the nearest integer) will the CO level exceed the permissible limit.
If this isn't the answer, let me know and i'll figure out what it is. But I believe this is it. :) </span>
