Given parameters:
Acceleration of the car = 1.6m/s
Initial speed = 80km/hr
Final speed = 110km/hr
Solution:
Time taken to achieve this speed = ?
Solution:
Acceleration is the rate of change of velocity with the time taken.
Mathematically;
a = 
where a is the acceleration
V is the final velocity
U is the initial velocity
T is the time taken
Now make the unknown time the subject of the expression;
aT = V - U
T = 
Convert the given acceleration to km/hr;
1.6m/s = 1.6 x 
x 
x 
= 5.76km/hr
Input the parameters and solve;
T = 
= 5.2hrs
The time taken is 5.2hrs
Answer:
2.11 %
Explanation:
In acidic medium iron is in Fe ⁺³ oxidation state .
Equivalent weight = 56 / 3
= 18.33 gm
acid used in titration
= 16.37 mL of .0233 M
= 16.37 x .0233 mL of M soln
= .38 mL of M soln
.38 mL of M soln reacts with .3298 gm of ore
1000 mL of M soln = (.3298 / .38) x 1000 gm of iron ore
867.89 gm
This must contain one gm equivalent of iron
or 18.33 gm
867.89 gm of ore contains 18.33 gm of iron
mass % of iron in the given ore
= (18.33 / 867.89) x 100
= 2.11 %
Answer:1.04 N
Explanation:
Given
Gravitational Force on the Platter is 
Tray makes an angle of 
This gravitational Force has components along and Perpendicular to Platter
Perpendicular Force 
Along the Tray
Thus 1.04 N is the magnitude of force that will cause Platter to slide down
The collision of the two waves would bring force and that would make the new wave smaller
