Answer:
J
Explanation:
= length of the rope connected = 13.4 m
= Angle made by the rope with the vertical = 72.4°
= height gained by the batman above the reference point
Height gained by the batman above the reference point is given as

= mass of batman = 89.5 kg
= acceleration due to gravity = 9.8 ms⁻²
Work done against gravity is same as the gravitational potential energy gained by batman and is given as


Inserting the above values

J
You really can't tell.
Power = I^2 × R = V^2 / R ( unit in Watt)
For P = I^2 × R
Where we have P directly proportional to R, increase in Power leads to increase in R
So if we have 100 will have higher resistance
For P = V^2/R
Power is inversely proportional to resistance.
So increase in Power leads to decrease in resistance.
60 watt will have a higher resistance.
Answer:


Explanation:
As we know that the force between two small spheres is given as

here we know that
= charges on two small spheres
r = distance between two spheres = 0.15 m
now the force between them is given as


now when two spheres are connected together then the charge on them is equally divided

now the force between them is given as



so here we have


Calculate the pressure due to sea water as density*depth.
That is,
pressure = (1025 kg/m^3)*((9400 m)*(9.8 m/s^2) = 94423000 Pa = 94423 kPa
Atmospheric pressure is 101.3 kPa
Total pressure is 94423 + 101.3 = 94524 kPa (approx)
The area of the window is π(0.44 m)^2 = 0.6082 m^2
The force on the window is
(94524 kPa)*(0.6082 m^2) = 57489.7 kN = 57.5 MN approx
Answer:the first one was x
