Answer:
Option (c) will be correct answer that is it will go 1.6 m
Explanation:
We have given that conveyor has the velocity u = 3.1 m/sec
Mass of the robot = 10 kg
static friction coefficient = 0.5 and kinetic friction coefficient = 0.3
Acceleration due to gravity g = 9.8 
Acceleration a = kinetic friction coefficient ×g = 0.3×9.8 = 2.94
Now according to third equation of motion
Finally velocity of the conveyor will be zero
So 
s = 1.6 m
So option (c) is correct option
<span>The distance covered by the tectonic plate, in meters, is
</span>
<span>
The time taken for the tectonic plate to cover this distance is equal to
</span>
<span>
Therefore, the average velocity of the tectonic plate is the ratio between the distance covered and the time taken:
</span>
<span>
</span>
Answer:
D) -Q
Explanation:
The charge inserted will induce -Q charge on the inner surface and + Q on the outer surface of the shell . This charge is called bound charge because it remained attached with opposite charge inserted inside.
Ethylene glycol is termed as the primary ingredients in antifreeze.
The ethylene glycol molecular formula is C₂H₆O₂.
Molar mass of C₂H₆O₂ is = (2×12) +(6×1) + (216) = 62g/mol
Now that antifreeze by mass is 50%, then there is 1kg of ethylene glycol which is present in 1kg of water.
ΔTf = Kf×m
ΔTf = depression in the freezing point.
= freezing point of water freezing point of the solution
= O°c - Tf
= -Tf
Kf = depression in freezing constant of water = 1.86°C/m
M is the molarity of the solution.
=(mass/molar mass) mass of solvent in kg
=1000g/62 (g/mol) /1kg
=16.13m
If we plug the value we get
-Tf = 1.86 × 16.13 = 30
Tf = -30°c
Answer
given,
height of the dam = 15 m
effective area of water = 2.3 x 10⁻³ m²
Using energy conservation
v = 17.15 m/s
discharge of water
Q = A V
Q = 2.3 x 10⁻³ x 17.15
Q = 0.039 m³/s
